Abstract

We document a negative relation between inflation and aggregate equity mutual fund flows and

hypothesize that this relation is partly due to inflation illusion on the part of investors. Inflation

illusion occurs when investors assign lower equity valuations because they fail to incorporate the

effect of inflation into their estimates of nominal growth rates. Our results are robust to controls

for alternative explanations such as the proxy hypothesis which states that inflation proxies for

poorer future real cash flow growth and the risk hypothesis which states that periods of higher

inflation are associated with higher equity risk premia.

Page 2: Inflation and Equity Mutual Fund Flows

The mutual fund industry in the United States is large, with assets under management in 2013

amounting to over $10 trillion.1 A large literature has examined various aspects of equity mutual fund

performance such as the level and persistence of their performance, and whether certain fund/manager

characteristics are associated with superior performance.2 In addition researchers have studied the

determinants of the size of the mutual fund industry across the world and conclude that it is affected by

a country’s regulatory framework and other market characteristics.3 Researchers have also examined

the factors that affect the inflow of new money into individual funds and the impact of fund flows on

fund performance.4

While there is much work examining flows at the individual fund level, research examining the

aggregate flow of money into (and out of) equity mutual funds as a group is sparse. Factors affecting

flows into individual funds need not necessarily translate into a similar effect on aggregate fund flows.

For example, if an individual mutual fund decreases the amount of fees charged to investors, it could

experience an increase in fund inflows. However, if such flows are mainly due to investors moving their

investments from more expensive funds to this lower cost fund, such an exchange would not affect

fund flows at the aggregate level. We also know little about how macroeconomic factors influence

aggregate asset allocation decisions. This lack of knowledge exists despite the popular press frequently

commenting on such aggregate flows.5 In this paper, we address these questions by examining the

role that one macroeconomic variable – inflation – plays in determining the flow of money into equity

mutual funds at the aggregate, economy-wide level.

We focus on the effect of inflation on equity fund flows for several reasons. First, compared to

many other macroeconomic variables such as the default premium, the concept of inflation is relatively

easy for investors to comprehend since they regularly deal with the effects of inflation in other areas

of their day to day life. Second, news about inflation is frequently discussed in the media, suggesting

that investors have access to ample information about inflation. For example, a casual search for

the appearance of the term “inflation” in articles published in the New York Times during January

1Flow of funds accounts of the United States, Board of Governors of the Federal Reserve System.2Researchers have studied whether fund performance is related to the level of the fund’s industry concentration

(Kacperczyk, Sialm, and Zheng (2005)), the extent to which the portfolio holdings deviate from a passive index (Cre-mers and Petajisto (2009)), board connections (Cohen, Frazzini, and Malloy (2008)), the fund manager’s educationalbackground and age (Chevalier and Ellison (1999)), etc.

2009-December 2013 resulted in more than 2,500 hits, or about eleven articles per week. There were

only three articles that mentioned the phrase “default premium” during the same time period. While

some articles may pertain to other uses of the term “inflation” (e.g., grade inflation), a casual perusal

of the title of the first several articles suggested that they are primarily about price inflation in the

economy.6 More importantly, prior literature (discussed in more detail later) has documented an

important role for inflation in affecting stock prices. Researchers have documented a negative link

between inflation and stock returns (e.g., Bodie (1976), Fama and Schwert (1977)). Hence, if investors’

expectations of future stock returns are affected by inflation (whether in a rational manner or not),

then inflation could have a first-order effect on their asset allocation decision, i.e., their decision to

invest in equities.

It is not clear a priori that inflation should have an effect on the asset allocation decision of

investors. Standard portfolio theory suggests that if the mutual fund separation theorem holds,

then all investors will hold portfolios consisting of the risk-free asset and a portfolio of risky assets,

the relative weights depending on the investors’ risk aversion. Investors would achieve their preferred

asset allocation by varying the weights invested in the risk-free asset and the risky portfolio. However,

the composition of the risky portfolio itself (i.e., the mix of risky assets such as stocks and bonds)

would be identical across all investors. Further, given a vector of expected returns and the associated

covariances, the mix of stocks and bonds should not change. However, if news about inflation causes

investors to reassess their estimates of expected returns, then they could change the mix of risky

assets in their portfolio. In particular, if inflation news causes them to perceive particular assets

as overpriced (i.e., they expect negative risk-adjusted returns or “alpha” in the future), it may be

optimal to reduce the weight on such assets in their portfolio.7

The primary hypotheses that we test are (a) does inflation, in the aggregate affect investment in

equity mutual funds, and (b) is this relation primarily the outcome of inflation illusion on the part of

mutual fund investors? If, as prior research finds (e.g., Bodie (1976), Fama and Schwert (1977)), high

inflation is associated with lower stock returns, then we expect investors to respond by moving their

assets away from equities, leading to an outflow of funds from equity mutual funds. One possible

6A similar search during 1989-1993 resulted in over 1,000 articles that mention inflation and zero articles that mentionthe phrase “default premium”.

7Pastor (2000) (page 181) states that when investors have prior beliefs that some assets have a mispricing alphawithin the CAPM, “... one should invest (disinvest) in any asset whose α is positive (negative), since combining theasset with the market portfolio increases the portfolio’s Sharpe ratio.” See also Ferson and Lin (2014).

reason for such an effect could be inflation illusion on the part of investors.

Inflation illusion (also called money illusion) occurs when investors confuse nominal and real

growth rates. Under the inflation illusion hypothesis, Modigliani and Cohn (1979) argue that investors

in the stock market incorporate the effect of inflation into their estimates of discount rates but not

into their estimates of long-term cash flows. Hence, during times of high inflation, investors discount

unchanged real cash flows at the higher nominal discount rate, leading them to assign lower intrinsic

value to stocks. Ritter and Warr (2002) and Cohen, Polk and Vuolteenaho (2005) empirically show

that inflation illusion significantly affects stock returns. The expectation of lower stock returns (or

a negative perceived alpha) would lead investors to reallocate assets away from equities and into

other assets such as money market securities and bonds. Our investigation seeks to tie together the

recent work that has examined the impact of inflation illusion in the stock market with the fund flow

literature to examine the impact of inflation on aggregate flows into equity mutual funds.

In addition to the inflation illusion explanation, we consider two other competing explanations

for why investors may shun stocks during periods of higher inflation. First, Fama’s (1981) proxy hy-

pothesis argues that the negative link between inflation and stock returns is a proxy for the positive

association between stock returns and real economic activity. He argues that the more fundamental

negative relation between inflation and real activity results in an observed negative association be-

tween inflation and stock returns. All else equal, stock market investors would respond to the lower

stock returns by reallocating their assets away from stocks and into other assets such as bonds and

cash (risk-free investments). Second, the risk hypothesis (see for example Brandt and Wang (2003)

and Bekaert and Engstrom (2010)) suggests that periods of high inflation coincide with high levels of

economic uncertainty and/or high levels of risk aversion. Higher risk aversion on the part of investors

would lead to a reallocation of assets away from more risky securities (i.e., equities) and into less

risky securities (bonds and money-market instruments). We do not consider a third explanation that

argues that the adverse effect of inflation on share prices is due to taxes (e.g., Feldstein (1980)).

Rydqvist, Spizman, and Strebulaev (2013) argue that tax incentives are the primary factor that has

affected the holdings of stocks in retirement plans, including mutual funds and pension funds. But

Thaler (1999) and Agnew, Balduzzi, and Sunden (2003) suggest that investors rarely trade or actively

rebalance their pension portfolios, suggesting that the tax-sensitive component of mutual fund assets

(that is invested in mutual funds via retirement plans) is less likely to be adjusted in response to

3

Page 5: Inflation and Equity Mutual Fund Flows

inflation. Hence we do not consider the tax explanation in our analysis.

We use data on mutual fund flows from the Flow of Funds Accounts of the United States issued

by the Board of Governors of the Federal Reserve System over the years 1976 to 2013 (flow of funds

data, hereafter) to conduct our analysis. Specifically we test whether inflation and empirical proxies

for inflation illusion have a first order effect on aggregate equity mutual fund flows after controlling for

other factors (e.g., level of economic activity, risk aversion, prior stock market performance, etc.) that

may affect such fund flows. We caution that we are not postulating that every investor behaves in

such a manner. Rather, our hypothesis asserts that if a sufficiently large number of investors behave

as predicted, then we should observe a measurably large effect of inflation (or inflation illusion) on

equity fund flows. We also note that since we are examining aggregate fund flows, variables that

characterize individual mutual funds such as their performance, fees and expenses and fund family

association are not viable explanatory factors.

We first investigate whether inflation has an effect on the flow of funds into equity funds. We

find that the level of inflation is negatively correlated with aggregate flow to equity mutual funds.

This result is both statistically and economically significant. Our point estimates suggest that a one

standard deviation increase in inflation is associated with a 0.45% decrease in the rate of equity mutual

fund flows in the next quarter (deflated by the US GDP). In dollar terms, this decrease translates to

roughly $27 billion fewer dollars flowing to equity funds.8

Second, we test whether the effect of inflation on equity fund flows is due to the inflation illusion

hypothesis, after including controls for two other potential explanations for the inflation - asset

flows relation (the proxy and the risk explanations). We consistently find that proxies for inflation

illusion are negatively related to aggregate inflows into equity mutual funds in the subsequent quarter.

Our results are not artificially driven by prior stock market returns driving the subsequent asset

reallocation since we explicitly control for prior returns in our analysis. Our results continue to hold

even after we include controls for the proxy and the risk explanations.

We extend our analysis to examine the impact of inflation illusion on flows into other asset classes -

bond mutual funds, money market funds, and bank deposits. We expect the impact of inflation illusion

on flows into these other asset classes to be weaker since the nominal cash flows received by investors

in these securities are fixed and unlike equity cash flows, do not need adjustment for the effects of

8The mean quarterly flow into equity funds is about $60 billion.

Page 6: Inflation and Equity Mutual Fund Flows

inflation. Further, investors may view them as substitute investments and respond to inflation by

moving money away from equity mutual funds and into bond/money market mutual funds and/or

deposits. We find a negative or no link (depending upon the specification) between inflation illusion

and flows to bond funds and money market funds. However, we find that flows into bank deposits

is positively associated with inflation illusion. This finding suggests that when investors respond to

inflation illusion by reducing flows to equity mutual funds, the money is reallocated primarily into

relatively safe bank deposits. The impact on flows into bond and money market funds is negligible.

We believe that to the best of our knowledge these results are new to the literature. We are aware

of two other papers that examine aggregate fund flows into mutual funds. Kamstra, Kramer, Levin,

and Wermers (2012) find that there is a seasonal effect in mutual fund flows. Specifically, they find

that funds flow away from equities and into money market and government bond funds in the Fall, and

back to equities in the Spring. They argue that such behavior is consistent with a seasonal pattern

in investor’s appetite for risk, with investors being more averse to financial risk in fall/winter rather

than in the summer. Chalmers, Kaul, and Phillips (2011) examine whether economic conditions affect

the aggregate asset allocations of U.S. mutual fund investors and find that they do. However, neither

of these papers examines whether inflation and inflation illusion affects how investors allocate their

wealth to equities, which is the main issue tackled in this paper.

To summarize, our results suggest that the inflation illusion hypothesis has a first order effect on

aggregate flows into equity mutual funds and is able to explain why high inflation induces mutual

fund investors to reduce flows to equity mutual funds and into safer assets such as bank deposits. At

a broader level, our results may at least partially explain the finding that periods of high inflation

depress stock prices and hence are followed by higher returns (as documented in, for example Campbell

and Vuolteenaho (2004)). The selling pressure arising from reallocations away from equity mutual

funds could temporarily depress equity prices to below fundamental value, leading to superior future

returns. While suggestive, we leave a more complete examination of this effect to future research.9

The rest of the paper is organized as follows. Section 1 provides a brief overview of the related

literature and develops the specific hypotheses that we test in the paper. Section 2 discusses the data

and methodology and Section 3 presents the results in the paper. Section 4 concludes the paper.

9Prior research (e.g., Warther (1995), Edelen and Warner (2001)) finds that aggregate fund flows affect returns, butdoes not examine whether fund flows arising due to the effects of inflation illusion are the main driving force for suchan effect.

1 Literature review and hypotheses

In this section we discuss the relevant literature and develop our hypotheses. First, we provide a brief

overview of the literature that examines the effect of inflation on equity values and its expected effect

on the investors’ aggregate equity market investments. We then discuss inflation illusion as a possible

explanation for investors’ reaction to inflation. We also briefly review two other possible explanations

– Fama’s (1981) proxy hypothesis and the risk hypothesis – that could explain why investors may

alter their asset allocations in response to inflation. Finally, we also briefly review the literature that

examines inflows into mutual funds, both at the individual fund level and at the aggregate level.

1.1 Inflation and equity values

The negative relation between inflation and equity values has been well-documented. For example,

Fama and Schwert (1977) find that common stock returns are negatively related to expected inflation.

The negative relation is also observed in the Fed Model (not endorsed by the Fed) that is commonly

used by practitioners. The Fed model postulates a positive relation between the earnings yield on

stocks and the yield on long term government bonds, even though such a relation is troubling from a

theoretical viewpoint because stocks are claims on real cash flows and their values should be immune

to changes in the level of inflation. In any case, if stock returns are negatively associated with

inflation, we would expect investors to react by moving their assets away from equity mutual funds

when inflation levels are high.

Our first hypothesis tests this relation. Specifically, we test whether the aggregate flows into stock

mutual funds are correlated with inflation. If high inflation levels indicate lower stock returns, we

expect equity mutual funds to experience fund outflows as investors reallocate their assets away from

stocks, leading to a negative link between inflation and equity fund flows.

Hypothesis H1: When the level of inflation is high, investors will reduce their investment in

equities, resulting in a negative correlation between inflation and equity fund flows.

In the following two subsections, we discuss possible reasons for the relation between inflation

and equity returns - the inflation illusion hypothesis, and two alternative explanations, the proxy

hypothesis and the risk hypothesis.

6

Page 8: Inflation and Equity Mutual Fund Flows

1.2 The inflation illusion hypothesis

Inflation illusion arises when investors confuse nominal and real returns when valuing economic op-

portunities. In one of the earliest works on inflation illusion and stock prices, Modigliani and Cohn

(1979) argue that inflation illusion results in misvaluation of stock prices. They specifically argue that

investors make mistakes when valuing stocks in the presence of inflation, confusing nominal and real

growth rates. They correctly interpret higher inflation as indicating a higher discount rate in their

valuations, but do not incorporate the higher inflation rate into their estimates of (higher) nominal

growth. This capitalization rate error is, in effect, the act of valuing a real cash flow using a nominal

discount rate. Equivalently, investors may correctly use nominal discount rates to discount nominal

cash flows, but fail to adjust the nominal cash flows upwards to reflect the higher inflation.10

Following Modigliani and Cohn (1979), several authors have found support for the basic hypothesis

that investors suffer from inflation illusion and undervalue stocks during periods of high inflation (e.g.,

Cagan (1982) and Cohn and Lessard (1981)). Ritter and Warr (2002) undertake a comprehensive

study of the Modigliani and Cohn (1979) hypothesis and examine the impact of inflation on the Dow

30 stocks over a twenty-year time period. They find that stocks are undervalued during periods of

higher expected inflation and that this undervaluation is correlated with future returns. Campbell

and Vuolteenaho (2004) use the Campbell and Shiller (1988) model to decompose the D/P yield into

its underlying discount rate and dividend growth components to examine the effect of inflation on

stock prices. They show that high inflation leads to stock market underpricing and low or negative

inflation leads to overpricing.

Researchers have examined whether such an inflation illusion also exists in other related areas.

Cohen, Polk and Vuolteenaho (2005) examine the effect of inflation illusion on the ability of the

CAPM to predict returns. They find that inflation illusion causes the market’s subjective expectation

of the equity premium to deviate systematically from the rational expectation. They document that

stock market investors suffer from inflation illusion, and conclude that “...to the extent that investors

perceive a benefit from valuing stocks using nominal quantities, they should pay more attention to

expected inflation when forecasting future nominal cash flows.” Chordia and Shivakumar (2005) find

that inflation illusion causes firms whose earnings are positively related to inflation to be undervalued

because investors don’t incorporate the effect of inflation when estimating future earnings. Focusing

10Chordia and Shivakumar (2005) find that lagged inflation significantly predicts subsequent corporate earnings.

7

Page 9: Inflation and Equity Mutual Fund Flows

on asset bubbles, Chen, Lung, and Wang (2009) find that while inflation illusion can explain the level

of mispricing, it does not explain the volatility of mispricing. Finally, Brunnermeier and Julliard

(2008) test the effect of the Modigliani and Cohn hypothesis on house prices and conclude that home

buyers suffer from inflation illusion.

If investors in general suffer from inflation illusion and are unable to accurately incorporate the

effects of inflation into their cash flow estimates and valuation, could sophisticated intermediaries not

resolve the problem by providing accurate forecasts that take the impact of inflation into account?

For example, equity research analysts provide earnings forecasts to stock market investors. If they

are sophisticated intermediaries, they could correctly incorporate inflation into their cash flow and

earnings forecasts and thus counteract an investor’s bias. The evidence however, does not support

this conjecture, as Sharpe (2002) finds that analysts suffer from inflation illusion in their forecasts and

that these errors are impounded into the P/E ratio. Furthermore, Basu, Markov, and Shivakumar

(2010) examine financial analysts’ forecasts for individual stocks and conclude that their evidence is

consistent with analysts not fully incorporating inflation-related information into their forecasts.

In summary, the inflation illusion hypothesis predicts that high inflation will result in the under-

valuation of equities. The lower estimate of value would lead investors to move their assets away from

equities, resulting in an outflow from equity mutual funds.

Hypothesis H2: Under the inflation illusion hypothesis (as in Modigliani and Cohn (1979)), there

will be a negative relation between equity fund flows and measures of irrational mispricing by investors

(mispricing induced as a result of inflation illusion).

1.3 Other explanations for the inflation - equity value relation

Several other mechanisms have been suggested that could explain how inflation affects stock prices

and hence, affects flows into equity funds. While the inflation illusion hypothesis assumes investor

irrationality, we consider two alternative explanations that are grounded in rational investor behavior.

The first explanation is the so-called proxy (or growth) hypothesis articulated by Fama (1981).

Fama argues that high inflation does not have a direct effect on equities, but works through an indirect

mechanism as a proxy for slower real economic growth. Briefly, a decline in expected real activity

would lower the demand for money, in real terms. Holding the nominal money and the interest rate

8

Page 10: Inflation and Equity Mutual Fund Flows

constant, this decline in demand for money would result in an increase in prices, i.e., higher inflation.

If inflation serves as a proxy for weaker future economic conditions and there is a positive association

between real activity and stock prices (i.e., the stock market rationally capitalizes real economic

activity), then we would expect higher inflation to be associated with lower stock returns. However,

this relation does not imply that higher inflation causes lower stock returns. Rather, the fundamental

negative link between inflation and real activity results in a negative link between inflation and stock

returns since the stock market rationally capitalizes the expected (lower) future real activity. In such

a case, investors may rationally reduce their exposure to equities during periods of high inflation.11

A link between inflation and equity values could also exist if periods of higher inflation are associ-

ated with greater economic uncertainty and high levels of risk aversion (the risk hypothesis). Brandt

and Wang (2003) formulate a model in which aggregate risk aversion is affected by inflation news, and

present empirical evidence to support their argument. They suggest that a possible behavioral reason

could be “...the anxiety consumers expressed about inflation in the recent survey of Shiller (1996).”

If consumers (who could also be investors) fear rigid nominal wages in the face of higher inflation,

they could become more risk averse during inflationary periods. Bekaert and Engstrom (2010) also

argue that risk aversion could increase during inflationary periods. During recessionary periods, the

economic uncertainty may induce high risk aversion on the part of investors. Further, if inflation

is also high when the economy is weak, we would observe a positive link between inflation and risk

aversion. As a result, investment classes which derive much of their value from future (uncertain)

cash flows are likely to be significantly impacted by this uncertainty. From an equity valuation point

of view, the higher risk aversion associated with high inflation periods would manifest itself in the

form of higher equity risk premiums and lower equity values. Again, we would expect mutual fund

investors to reduce their allocations to equity mutual funds in the face of lower (expected) equity

values, until the equity values adjust to provide an expected return consistent with these new risk

tolerances.

In our empirical tests of Hypothesis H2, we include control variables as proxies for these two

explanations for the inflation – equity fund flows relation.

11A related explanation is the so-called “policy anticipation effect” in which investors anticipate the central bank’saction of raising interest rates when inflation exceeds a target rate. Thus an increase in inflation would signal a tighteningof monetary policy, which is likely to have a negative effect on stock prices.

1.4 Mutual fund flows

Our main objective is to examine whether inflation and inflation illusion affects aggregate equity fund

flows. Hence, factors that may lead investors to choose to redirect their investments from one equity

fund to another (maybe in response to lower performance or higher fees etc.) are not relevant when

we examine aggregate flows into equity funds since reallocating money among equity funds will net

out at the aggregate level. However, for completeness, we summarize a few representative papers in

the mutual fund flow literature that examine factors affecting fund flows and caution that this is by

no means a comprehensive summary of this vast body of research.

In an important early paper in this area, Sirri and Tufano (1998) find that mutual fund investors

exhibit return chasing behavior and invest their funds disproportionately into funds that did well in

the prior period. Sirri and Tufano (1998) and Jain and Wu (2002) find evidence consistent with the

existence of search costs and show that when the fund is well known (e.g., via advertising the fund),

the impact of prior performance on fund flows is significant. Massa (2003) examines the impact of

load fees and fund family affiliation (number of different funds offered by the fund family) on the

stability of the fund flows. Nanda, Wang and Zheng (2004) examine the flow of funds into a fund

family and show that there is a positive spillover effect of “star performance” on the fund flows both

into the fund and into other funds in the same family.

Several authors have also examined the link between mutual fund flows and fund performance.

Zheng (1999) finds that funds that receive more inflows perform better subsequently. However,

Frazzini and Lamont (2008) examine flows within the mutual fund sector and test whether investor

sentiment is related to these flows. They find support for the “dumb money” explanation in which

retail investors move money to funds that invest in stocks in which there is high investor sentiment,

which perform poorly subsequently.

The extant studies, such as the ones discussed above, primarily focus on the causes and effects

of flows into individual funds or into funds aggregated at the family level. They do not focus on the

determinants of fund flows at the aggregate, economy-wide, level. In an early study, Warther (1995)

finds that mutual fund flows are correlated with concurrent stock returns and that an inflow of funds

into stock mutual funds results in positive stock returns. However, he does not examine the impact

of inflation on aggregate fund flows. We are aware of two recent studies that are closer in spirit to

our study. Kamstra, Kramer, Levin, and Wermers (2012) document a seasonal effect in mutual fund

10

Page 12: Inflation and Equity Mutual Fund Flows

flows. Specifically, they show that investors move their funds away from equities and into money

market and government bond funds in the Fall, and back to equities in the Spring. They suggest that

such investor behavior is the outcome of seasonality in investors’ risk preferences, being more averse

to financial risk in the fall/winter season and being more receptive to taking on risk in the summer.

More closely related to our paper, Chalmers, Kaul, and Phillips (2011) examine whether economic

variables such as the level of economic activity in the economy, the term and default spread, stock

and bond market volatility etc., affect the aggregate asset allocations of U.S. and Canadian mutual

fund investors. They conclude that when the economy is expected to perform well, investors direct

more of their investments towards equity funds. However, neither of these papers address the main

issues that are examined in our study: (a) whether inflation affects how mutual fund investors allocate

their wealth across different asset classes, and (b) the proposed mechanism - inflation illusion, Fama’s

(1981) proxy for growth, or risk - by which such an inflation effect might work.

2 Data and method

2.1 Data

We use the Federal Reserve Flow of Funds data to measure aggregate mutual fund flows at the

quarterly level from 1977 to 2013. The Flow of Funds tables that we rely on are F.120 - Money

Market Funds (mm), F.121 - Mutual Funds (mf), and F.122 Closed End (cef) and Exchange Traded

Funds (etf). We also gather data from F.204 - Checking Deposits (check) and F.205 - savings deposits

(save). All data is seasonally adjusted. From these data, we create four broad categories of flows –

Flows to Equity Funds, Bond Funds, Cash/Money Market Funds and Bank Deposits – as follows.

To create our flow measures, we combine specific line items from several flow of funds tables. For

example, flows into bond funds appear in Closed End Funds (cef), Exchange Traded Funds (etf),

Mutual Funds (mf) and Money Market Funds (mm). The definitions of each of our four fund flows

categories are as follows:

EquityF lows = equitiescef + equitiesetf + equitiesmf

11

Page 13: Inflation and Equity Mutual Fund Flows

BondF lows = treasuriescef +muniscef + corporatescef + treasuriesetf +munisetf

+ corporatesetf + treasuriesmf + agenciesmf +munismf + corporatesmf

+ corporatesmm +miscmm

MoneyMarketF lows = fedfundsmf + commercialpapermf + checkingmm

+ timesavingsmm + fedfundsmm + openmarketmm

Deposits = checkingdepositschec + savingsdepositssave

We deflate the fund flow to each specific category by the nominal U.S. GDP. The resulting variable

that we use in our main empirical analyses is the quarterly flow to equity funds as a percentage of

GDP. We use flows into bond funds, money market funds and deposit accounts in our supplementary

analyses.12

Since the fund flows data is quarterly, we measure all other variables on a quarterly basis. To

control for potential return chasing behavior, we use the stock market return as a control variable,

measured as the quarterly return on the value-weighted market index, with distributions, from CRSP.

We obtain inflation data from the Fred database maintained by the St. Louis Federal Reserve Bank.

The appendix contains a list of all our explanatory variables, their definitions and data sources.

2.2 Measuring mispricing associated with inflation illusion

We measure the extent of mispricing induced by inflation illusion using the method of Campbell

and Vuolteenaho (2004), Campbell and Shiller (1988), and Campbell (1991). This approach has

been widely utilized in the literature to examine the effect of inflation illusion (e.g., Brunnermeier

and Julliard (2008), Chen, Lung, and Wang (2009)). Campbell and Vuolteenaho (2004) model

the mispricing caused by inflation illusion by considering objective versus subjective opinions about

returns and growth rates. Objective opinions are those that are free from bias, whereas the subjective

12As a robustness check, we also deflate fund flows by the aggregate total assets in that category (equity funds, bondfunds, money market funds, or bank deposits), in that quarter, and obtain qualitatively similar results.

12

Page 14: Inflation and Equity Mutual Fund Flows

opinions contain the potential for inflation illusion. From the Gordon growth model of stock valuation

and assuming constant dividend growth, we can express the dividend yield as:

Dt+1

Pt= R−G, (1)

where D is dividends, P is the price, R is the nominal cost of equity and G is the nominal expected

growth rate of dividends. Campbell and Vuolteenaho (2004) argue that there can be two sets of R and

G at any given time – an objective set (denoted with superscript O), and a subjective set (denoted

with superscript S). However, since there is only one observed dividend yield at any point in time,

the difference between the objective R and the objective G must equal the difference between the

subjective variables:

Dt+1

Pt= RO −GO = RS −GS . (2)

With a little algebraic manipulation, we can derive the following:

Dt+1

Pt= RS −GO + (GO −GS). (3)

The term in parentheses, the difference between the objective and subjective estimates of growth,

is the measure of mispricing due to inflation illusion. This mispricing occurs when investors do not

include inflation in their subjective estimate of G. Note that by construction, this mispricing could

equivalently be expressed as the difference between the objective and subjective costs of equity, R.

To estimate the mispricing component, Campbell and Vuolteenaho (2004) use the log-linear val-

uation model of Campbell and Shiller (1988). In the Campbell-Shiller model, the log dividend yield

is approximated (using a Taylor series expansion) as a function of the discounted future expected

returns and future dividend growth rates, where lower case variables indicate logged values:

dt−1 − pt−1 ≈k

ρ− 1+∞∑j=0

ρjEt−1ret+j −

∞∑j=0

ρjEt−1∆det+j . (4)

Returns and dividends (re and de) are defined as returns in excess of the log risk free rate. ∆de is

therefore the dividend growth in excess of the risk free rate. ρ and k are constants. In equation 4,

the second term on the right hand side is basically R and the third term on the right hand side is G.

13

Page 15: Inflation and Equity Mutual Fund Flows

These are either objective or subjective values, depending on how the expectations are taken.

We take equation 4 and apply the Campbell and Vuolteenaho (2004) VAR method to estimate

RO and the mispricing. Specifically we take a first-order VAR that includes the log return on the

S&P 500 index over the three-month Treasury bill (ret ), a risk premium measure (λt), measured as

the volatility of stock returns divided by the volatility of bond returns, the log dividend-price ratio

(dyt), and the exponentially smoothed moving average of inflation (πt). The VAR is re-estimated

every quarter, always using observations starting in the first quarter of 1962, to avoid any look-ahead

bias.

From the VAR, we first estimate the term∑∞

j=0 ρjEO

t−1ret+j under objective expectations. This

gives us ROt . The next step is to estimate mispricing by running a regression of RO

t on an intercept

and the risk-premium proxy λt. The mispricing is taken as the residual from the regression of∑∞j=0 ρ

jEOt−1r

et+j on an intercept and the risk-premium proxy λt:

ROt = α0 + α1λt + εt. (5)

The intuition for estimating the mispricing as the residual of this regression is as follows. If investors

do not suffer from inflation illusion, then a regression of excess stock returns on inflation should result

in no loading on the inflation variable. However, to the extent that investors do alter their estimates

of the excess expected return on stocks as a result of inflation, the objective R predicted by the VAR

will incorporate these errors. To extract these errors, equation 5 only relates returns to risk (and not

to inflation). Thus the residuals from this regression would be due to inflation induced mispricing.

We note that mispricing can be negative or positive, since it is clear from equation 5 that the

mispricing is defined as the residual. Both Chen, Lung, and Wang (2009) and Brunnermeier and

Julliard (2008) note that if investors have a reference level of inflation, then deviations from this

reference level will result in either a positive or negative pricing error.

2.3 Control variables for the proxy and risk hypotheses

The proxy or growth effect of inflation on stock prices can be seen by referencing our earlier equation

1:

Dt+1

Pt= R−G. (6)

14

Page 16: Inflation and Equity Mutual Fund Flows

If inflation has a negative effect on economic activity, then periods of higher inflation will result

in lower G and consequently a higher dividend yield (i.e., stocks are undervalued). We use two

variables to measure this “proxy” or growth effect. The first is the term premium since Fama and

French (1989) show that the term premium captures short-term business cycle conditions (low near

business cycle peaks, and high near troughs) and is related to returns on stock and long term bonds.

Estrella and Hardouvelis (1991) also show that high term premiums predict an increase in future real

economic activity. We compute the term premium as the difference between the yield on 30-year

bonds and 3-month T-bills. The second variable used is the forecast of real growth in corporate

profits four quarters ahead, and is obtained from the Survey of Professional Forecasters, available at

the Philadelphia Federal Reserve Bank website.

If inflation is correlated with greater market risk, then this would result in a higher R in equation

6, which will result in a higher dividend yield. The risk effect is measured with the default premium

and stock market volatility. We expect high default premiums and high stock market volatility to

be associated with higher levels of risk aversion on the part of investors. We estimate the default

premium as the difference between the yield on BAA bonds and AAA bonds (obtained from the

FRED database at the St. Louis Federal Reserve Bank), which captures the risk premium associated

with investing in risky securities. The stock market volatility is measured as the rolling 60-month

standard deviation of the monthly return (with distributions) on the CRSP value weighted market

index.

3 Results

3.1 Summary statistics

Table 1 presents summary statistics for the sample. We have 149 quarterly observations spanning the

years 1976:Q4 to 2013:Q4. The first four variables in Table 1 pertain to the net flows to the various

asset classes, deflated by the U.S. GDP. The average flow to equity funds is 0.5% per quarter. The

average flow to bond funds is 1.5% per quarter and that into money market funds averages 0.56% per

quarter. The amount of bank deposits increases every quarter on average by 3.8%. The term premium

and default premium are, on average, positive as one would expect. During our sample period, both

inflation and estimates of inflation illusion exhibit significant variation. Inflation averaged about

15

Page 17: Inflation and Equity Mutual Fund Flows

4% but ranged as high as nearly 15% in the early 1980s and near zero in the late 2000s. Average

mispricing is zero by construction (as discussed earlier), but there is significant variation with periods

of both positive and negative mispricing. Positive mispricing implies that the inflation illusion effect

is high and stocks are underpriced, while negative mispricing implies that inflation is below investor’s

reference rate and stocks may be overvalued.

In Table 2, we present correlations between the variables used in our study. There is a positive

correlation between flows into equity mutual funds and flows into bond funds and money market

funds, even though the estimates are not statistically significant. However, there is a strong negative

correlation between equity fund flows and flows into bank deposits. Of particular note is the significant

negative correlation between equity flows and inflation (-0.50), depicted visually in Figure 1. The

correlation of inflation with bond fund flows is also negative but the magnitude is smaller (-0.265),

whereas flows into money market funds are not associated with inflation. In sharp contrast, bank

deposits are significantly positively associated with inflation (0.21).

Turning to each of our hypotheses for the effect of inflation on equity fund flows, we find that the

two growth variables – term premium and expected growth in corporate profit – are not significantly

correlated with equity flows. Of the two risk explanatory variables, default premium is negatively

correlated with equity fund flows, a result consistent with its hypothesized effect. But, the correlation

with stock market volatility is significantly positive, opposite of the prediction of the risk hypoth-

esis. Finally, there is a significantly negative correlation (-0.36) between equity fund flows and the

mispricing variable, consistent with the inflation illusion hypothesis, depicted visually in Figure 2.

Both bond flows and money market flows are negatively correlated with the mispricing measure, but

deposit flows are significantly positively correlated (0.29) with the mispricing measure.

We also note that mispricing and inflation are not correlated in a significant manner. This result

indicates that the mispricing variable is not merely a noisy transformation of inflation. Figure 3

presents the time series of mispricing and inflation over our sample period. However, mispricing is

positively correlated with expected inflation (from the Survey of Professional Forecasters). Hence, we

conduct additional tests, both with and without controls for inflation, in order to more clearly isolate

the effect of inflation illusion on aggregate equity fund flows.

16

3.2 Inflation and equity prices

The underlying premise of our paper is that inflation depresses stock prices. To examine whether

this relation holds in our data set, we replicate a simple test that is presented in Campbell and

Vuolteenaho (2004) and examine the relation between inflation and the dividend to price ratio (or

dividend yield) for the S&P 500 Index. The basic model is as follows:

D

P t= α0 + α1λt + α2πt + εt, (7)

where DP t

is the dividend to price ratio, λt is a risk premium measure estimated as the volatility of

stocks divided by the volatility of bonds and πt is exponentially smoothed inflation. We estimate

equation 7 (using Newey-West corrected standard errors) and report the results in Table 3.

We find a strong positive relation between smoothed inflation, π and the dividend to price ratio,

indicating that during periods of higher inflation, the dividend yield on stocks is higher, indicative

of lower stock prices. This finding is similar to that reported by Campbell and Vuolteenaho (2004),

who also find a positive relation between inflation and the dividend yield. We note that the R2 of

56.2% is also in line with that reported in the earlier study.

3.3 Inflation and fund flows

Given the positive relation between inflation and the dividend yield, indicating that stocks prices

are relatively lower during inflationary periods, we now turn our attention to investigating whether

investors respond via their asset allocation decisions. We report the results of multivariate analyses

that test hypothesis H1, which postulates a negative relation between inflation and inflows into equity

mutual funds. As discussed above (Table 2), there is a strong negative correlation between inflation

and equity fund flows at the univariate level.

Table 4 presents the results of baseline regressions where the dependent variable is the quarterly

inflow into equity mutual funds and main explanatory variable of interest is the level of inflation.13

We include the lagged quarterly market return as a control variable to account for the possibility of

investors’ return chasing behavior. In model 1, we find some evidence of return chasing behavior,

since the coefficient on lagged market return is significantly positive (t=2.4). Importantly, we find

13In these and all subsequent regressions, we use the Newey-West corrections to control for autocorrelation.

17

Page 19: Inflation and Equity Mutual Fund Flows

that the level of inflation is significantly negatively related to subsequent equity fund flows (t = -

7.7). This result is consistent with our hypothesis H1 that during periods of high inflation, investors

will move their assets away from equities. The results are also economically significant. Our point

estimates suggest that a one standard deviation increase in inflation will result in a decline of 0.45%

in quarterly equity fund flows, which represents about $27 billion per quarter. In model 2, we use

contemporaneous explanatory variables instead of lagged values and find substantially similar results.

Again, we find that equity flows are significantly negatively related to the level of inflation. We

present these results graphically in Figure 1, which shows equity flows plotted against inflation.

3.4 The impact of inflation illusion on the equity fund flow relation

We now turn our attention to testing hypothesis H2, which states that the link between inflation and

equity fund flows is the outcome of inflation illusion on the part of investors. The dependent variable

in these models is the equity fund flow. The main explanatory variable of interest is mispricing,

which is our measure of inflation illusion (as defined earlier). Also included in the regressions are

controls for market returns and the proxy and risk explanations. We also present the results of several

alternative specifications that we used to test the robustness of our results. All our regressions present

Newey-West corrected t-statistics.

In model 1 in Table 5, we include the lagged term spread (to control for the proxy explanation),

the lagged default premium (to control for the risk explanation), and lagged market returns as control

variables. We find that the coefficient on mispricing is negative and significant (t=-3.0), consistent

with the inflation illusion explanation (hypothesis H2). In other words, as mispricing induced by

inflation illusion increases, the net flow of funds into equity funds decreases. We find that the term

spread is positively related to equity flows (as predicted by the proxy hypothesis). The coefficient on

default premium is negative and significant (t=-3.2), suggesting that investors move their assets away

from equities during periods when the investors are more concerned about risk, i.e., default premium

is high.

Models 2-4 are similar, except that we replace our proxy and risk explanatory variables one at a

time and examine the effects of alternative measures of these important control variables. In Model

2, we use the stock market volatility instead of default premium to measure risk. We find that the

coefficient on market volatility is negative and significant, consistent with the predictions of the risk

18

Page 20: Inflation and Equity Mutual Fund Flows

explanation. We continue to find that the coefficient on the inflation illusion variable is negative and

significant (t = -3.05) and that on the term spread is positive and significant. Models 3 and 4 replicate

models 1 and 2, except that we use the forecasted corporate profit growth instead of the term spread

to capture the proxy effect. Our main result continues to hold. In both specifications, the coefficient

on the inflation illusion variable is negative and significant (t = -3.09 and t = -3.08, respectively).

We continue to find mixed results for the risk explanation, with the coefficient on default premium

being negative as predicted, but that on market volatility being significantly positive, the opposite of

our expectation under the risk hypothesis. The coefficient on forecasted profit growth is positive and

significant in both models, consistent with the proxy hypothesis.

To summarize, in all four models, we find a statistically significant negative relation between

mispricing induced by inflation illusion and equity flows, suggesting that when investors are subject

to inflation illusion, they move their assets away from equities. This result provides strong support

for our hypothesis H2. Our results are also supportive of the proxy explanation, but the results are

mixed for the risk explanation.

3.5 Additional results

It is possible that aggregate equity flows shows some persistence. For example, Gallaher, Kaniel,

and Starks (2006) find evidence of persistence of flows into individual mutual funds. The persistence

may be the outcome of investors regularly investing in mutual funds via their retirement accounts.

Alternatively, if retail investors rely on media advertising or broker recommendations in making their

investment decisions and these effects persist for a period of time (e.g., a mutual fund advertising

campaign can cover several quarters where they market funds that have performed well in the recent

past, see Jain and Wu (2002)), we could observe persistence in fund flows. In any case, if there is

persistence in flows at the individual fund level, there may be persistence in flows at the aggregate

level also. Therefore, we replicate the analysis in models 1-4 in Table 5 but include lagged equity

flows as an additional control variable. The results are tabulated in Table 6.14 We find that the

coefficient on the mispricing measure remains negative and statistically significant in all models.

In Table 2, we reported a small (and statistically insignificant) positive correlation between in-

flation and mispricing. Therefore, it is unlikely that mispricing may simply be capturing the effect

14For brevity, in Table 6, we only tabulate the results from model 1 in Table 5. Detailed results for the other models2-4 are available from the authors upon request.

19

Page 21: Inflation and Equity Mutual Fund Flows

of inflation on equity fund flows. In any case, we repeat the analysis in Table 5 and add lagged

inflation as an additional control variable. We first include lagged inflation as an additional control

variable. Our results continue to hold. The results of replicating model 1 in Table 5 are reported

as model 2 in Table 6. We find that the negative effect of mispricing on equity fund flows persists,

even after controlling for lagged inflation. Furthermore, the coefficient on lagged inflation is negative

and statistically significant, suggestive of the positive effect of inflation on the dividend yield that

we reported in Table 3. We find (results not separately tabulated) similar results when we replicate

models 2-4 in Table 5, the coefficient on the mispricing remains negative and statistically significant

at the one-percent level. Second, we replace lagged realized inflation with forecasted inflation, using

the forecasts of the change in the GDP deflator (data from the Survey of Professional Forecasters,

available at the Federal Reserve Bank of Philadelphia). The results of replicating model 1 in Table 5

are reported as model 3 in Table 6.The coefficient on this measure of expected inflation is consistently

negative. Importantly, the coefficient on the mispricing variable remains negative and significant. We

find a similar result (not separately tabulated) when we replicate models 2-4 in Table 5.

Overall, our results offer consistent support for hypothesis H2, which argues that the mispricing

associated with inflation illusion (of the Modigliani and Cohn (1979) type) induces investors to move

away from equities during times when the mispricing effect is large. Our results are less supportive

of the proxy or the risk explanations.

3.6 The effect of inflation illusion on flows to other asset classes

Our results are supportive of the hypothesis that inflation induced valuation errors leads to a net

decrease in flows to equity funds. We now examine whether a similar negative relation also exists

between inflation illusion measures and flows into three other asset classes – bonds, money market

securities, and bank deposits. While theory predicts a negative impact of inflation illusion on equities,

the effect of inflation illusion on these fixed income assets classes is unclear.

First, there it could be argued that there should be no relation between fixed income flows and

inflation illusion because these assets have fixed nominal cash flows and are therefore not subject to

valuation errors based on differences in objective and subjective growth rates. However, if investors

are diverting funds away from equities during inflationary periods, then some other asset class must

be receiving these flows. If so, we could observe a positive link between measures of inflation illusion

20

Page 22: Inflation and Equity Mutual Fund Flows

and flows into non-equity asset classes. A third possibility also exists. If the fixed income asset class

is comprised heavily of corporate bonds, the value depressing effect of inflation illusion on firm value

may negatively impact the debt securities of those companies.15 This effect would result in a negative

relation between inflation illusion and flows to bond funds, but should not have an impact on flows

to other asset classes such as bank deposits. Clearly, the effect of inflation illusion on flows to debt

funds is an empirical question.

As documented earlier in Table 2, equity flows are not significantly correlated with flows into bonds

or money market assets, but are significantly negatively correlated with flows into bank deposits. This

suggests that investors park their assets in bank deposits during inflationary periods. In Table 7, we

replicate the analysis in Table 5 for the three asset classes separately - flows into bond funds, money

market funds, and bank deposits - and test our assertion more formally.16

The results indicate that investors move their assets away from bond funds when the level of

inflation illusion is high, similar to equities. In model 1 in Table 7, the coefficient on mispricing is

negative and weakly significant (t = -1.845). However, the significance levels are higher when we

replicate models 2-4 in Table 5, and all three coefficients are negative and statistically significant

at the ten-percent level or better. When we include lagged bond flows, then the coefficient on

mispricing becomes statistically insignificant in all four models (not separately tabulated). There

is little support for the proxy and the risk explanations since the coefficients on those variables are

generally not statistically significant.

The results in model 2 in Table 7 suggest that inflation illusion has a negligible effect on inflows

into money market funds. The coefficient on mispricing is negative, but is not statistically significant.

When we replicate models 2-4 in Table 5, the coefficient on mispricing is negative and significant in

two out of three models. When we include lagged bond flows, the coefficient on mispricing becomes

statistically insignificant in all four models (not separately tabulated). The risk explanation again

finds little empirical support since none of the coefficients are significant at the usual levels. However,

the proxy explanation now finds support, with investors moving their assets away from money market

funds when they expect future economic activity to be high.17

15This could occur, if, as a result of inflation illusion, investors believe that the firm will earn lower cash flows,negatively affecting bond values.

16Again, in Table 7, we only tabulate the specification from model 1 in Table 5 for brevity. Detailed results ofreplicating models 2-4 are not tabulated but are available upon request.

17This may be a mechanical association if it is corporations (rather than individual investors) who use their cash onhand (invested in money market accounts) to fund their investments in real assets, in anticipation of future growth.

21

Page 23: Inflation and Equity Mutual Fund Flows

Finally, we examine the flows to bank deposits, including checking accounts and CDs. The results

in model 3 in Table 7 indicate that inflation illusion has a significantly positive effect on inflows into

bank deposits. When we replicate models 2-4 in Table 5, the coefficient on mispricing is positive and

significant in all three models. When we include lagged flows into bank deposits, the coefficient on

mispricing remains statistically significant in all four models (not separately tabulated). This result

offers further support for the inflation illusion hypothesis. When inflation illusion is high, investors

reallocate their assets away from equities and invest in secure deposits with a guaranteed nominal

return. Bank accounts have the additional benefit that they are FDIC insured and are very liquid.

Further, retail investors, who are more likely to be subject to inflation illusion, are more likely to be

aware of bank deposits as a safe and liquid alternative asset class.

As an additional robustness check, we repeat the tests in Table 7 and control for lagged inflation or

expected inflation, as before. The results (not tabulated separately to conserve space) are qualitatively

the same as those reported above.

3.7 Impact on equity prices

The results presented above show that investors are subject to inflation illusion and move their assets

away from equities and primarily into bank deposits during inflationary periods. Relatedly, Campbell

and Vuolteenaho (2004) find that inflation illusion has a real and significant effect on dividend yields.

In particular, they find that dividend yield is positively related to the level of mispricing, indicating

that high inflation illusion is associated with depressed equity prices. We conjecture that the outflows

from equity funds due to inflation illusion could have a measurable, downward price pressure on

stock prices. In this scenario, the decrease in stock prices when inflation illusion is high would be

concentrated in periods when investors react to high inflation illusion by moving their assets away

from equities.

To test if a similar result exists in our data, we divide our sample based on whether the equity flows

are above or below median equity flows and whether the mispricing measure is positive or negative.

For each of the resulting four groups, we measure the dividend to price ratio for the aggregate stock

market and compare them across the groups.

We present the results of this analysis in Table 8. Of particular interest are the top right and

bottom left cells, which represent low levels of mispricing/high equity flows and high inflation illusion

22

Page 24: Inflation and Equity Mutual Fund Flows

and low equity flows. The average DP ratio for the low mispricing/high equity flows periods is 2.01%.

The average DP ratio for the high mispricing/low equity flows group is more than twice as large:

4.30%. The difference between these two values is highly significant (t = 13.41). In contrast, the

equity prices are not as depressed (mean DP ratio is 2.66%) when the mispricing is high but the equity

flows are also high and investors do not move their assets away from equities. At a broader level,

this result provides initial evidence that the investors’ asset allocation behavior documented here

(i.e., their tendency to move assets away from equities when they are subject to inflation illusion,

leading to downward pressure on equity prices) may have an important role to play in explaining

the link between inflation illusion and stock prices documented in Campbell and Vuolteenaho (2004).

However, we leave a detailed examination of this effect to future research.

4 Conclusion

In this paper we examine whether inflation affects flows into equity mutual funds at the economy-

wide level, and find that a high level of inflation consistently leads investors to reduce fund flows to

equities. One possible explanation for the link between inflation and equity fund flows is the inflation

illusion hypothesis, initially put forth by Modigliani and Cohn (1979). Under the inflation illusion

explanation, investors increase the discount rate used to value stocks when inflation increases, but

they fail to incorporate the effect of inflation into their estimates of nominal growth rate of cash flows.

The outcome is that investors will tend to undervalue stocks in the presence of inflation, leading them

to move their assets away from equities. Our tests reveal strong support for the inflation illusion

hypothesis.

In our analysis we control for two other explanations for the observed link between inflation and

equity fund flows - the proxy effect and the risk effect. The proxy effect states that inflation acts as

a proxy for poorer economic conditions, leading investors to rationally infer lower stock valuations.

The risk effect argues that investors will reduce their valuations of risky equity assets during periods

of high inflation either because inflation creates greater uncertainty in the macro economy or because

it increases investors’ risk aversion. Under both explanations, the lower stock valuation would lead

investors to move their assets away from equities and into other asset classes. Our tests offer little to

no support for these two explanations.

23

Page 25: Inflation and Equity Mutual Fund Flows

We also find that inflation illusion has explanatory power over the flows into deposit accounts.

We interpret this finding as being consistent with inflation illusion leading investors to reduce their

flows to equity and instead invest their money in deposits which are lower risk and have potentially

high nominal returns (due to inflation).
