Page 4: House Price Cycles and  the Real Economy

Research Questions

How similar are the cycles: in duration, amplitude, etc.?

How do the cycles relate to the interest rate changes?

Are the cycles synchronized, or does one lead the others?

How important are global versus local factors?

What are the policy implications?

Page 5: House Price Cycles and  the Real Economy

Literature—Domestic Context

Bank credit, house prices and aggregate demand tend to move in tandem

Financial accelerator effects through external finance premium and collateral prices result in procyclicality of bank credit Bernanke and Gertler, 1989; Kiyotaki and Moore, 1997

Liquidity and leverage of banks also contribute Adrian and Shin (2008), Berger and Bouwman (2008)

Liquidity of housing wealth and availability of housing financing can also alter the relationship through consumption and investment

Page 6: House Price Cycles and  the Real Economy

Literature—International Context

The degree of synchronization in real and financial cycles increased Kose, Prasad and Terrones, 2003; Imbs, 2004; Otrok and

Terrones, 2005

International comovement in house prices may reflect comovement of interest rates Especially with debt-financed ownership and

adjustable-rate mortgages

Global liquidity may have also contributed Belke and Orth, 2008

Page 7: House Price Cycles and  the Real Economy

Literature—Monetary Policy

Transmission through the credit channel and the housing market

Monetary policy, credit and asset prices Benign neglect: Monetary policy is not an effective

tool for targeting asset prices, so better not to prick the bubble but mop up afterwards (Bernanke, Gertler, and Gilchrist, 1999)

Leaning against the wind: Monetary policy needs to play a more proactive role to prevent financial bubbles (Borio and Lowe, 2002, and Borio, 2006)

Contribution of This Paper

Multidirectional links Goodhart and Hofman (2008)

Focus on output, bank credit, house prices (as well as residential investment) and interest rates

Descriptive approach GDFM as opposed to VAR

Data properties Unit root tests Filtering as opposed to differencing

Different horizons Short to medium term (6 to 16 quarters) Long term (16 to 32 quarters)

Page 9: House Price Cycles and  the Real Economy

Preview of Results

House price cycles lead credit and business cycles over the long run

Interest rates tend to lag other cycles at all horizons

Country cycles are largely driven by global factors the role of which has increased over time,

especially for credit and business cyclesU.S. cycles tend to lead other countries’

respective cycles

Generalized Dynamic Factor Model

Identifies a common component using a large number of series

Builds on the traditional factor models Sargent and Sims (1977) and Geweke (1977)

By allowing for serial correlation and weakly cross-sectional correlation of idiosyncratic components Chamberlain (1983) and Chamberlain and Rothschild

(1983)Recent examples

(Approximate) GDFM

where Yt is a (N x T) vector stochastic stationary process with zero mean and

unit variance and Xt and Ξt are (N x T) vectors of common and idiosyncratic

components, respectively. Xt can be written as:

where Ft is a (r x T) vector of common factors and C is a (N x r) matrix of factor

loadings.The model has N>>T and r<<N.The common factors assumed to follow an AR(1) process:

with B and (r x r) matrix and ut a (r x T) vector of residuals.

Measures of Comovement

The dynamic correlation varies between -1 and 1. Formally,

where the numerator is the cospectrum between y1 and y2 processes at frequency

λ and S (y1) and S (y2) are the spectral density functions of the processes at

frequency λ defined over –π and π.

Coherence is intrinsically related to dynamic correlation given by:

Coherence is symmetric and a real number between 0 and 1.

Page 13: House Price Cycles and  the Real Economy

The phase angle between processes helps identify the lead-lag relationship

where q (y1 y2) is the quadrature spectrum. Only when K (y1y2) ≠0, the phase angle converges in distribution to a normal random variable.

4. The KPSS test barely passes the confidence level. In addition, observation of the series suggests that it contains a unit root.5. When the ERS test on first differences does reject the I(1) null, a relatively higher error of type I is assumed for KPSS test (1 percent).

Table 1. Unit Root Tests

Notes: The table reports the results of two unit root tests: ERS (Elliott, Rothenberg, and Stock, 1996) and KPSS (Kwiatkowski, Phillips, Schmidt, and Shin, 1992). All tests were done including a constant and a trend. The number of lags was chosen using the Schwarz criterion and ensuring that no serial correlation is left in the residuals. Highlighting in the table identifies the cases where the two tests rendered conflticting results. In such cases, unit root tests were also done excluding a constant and trend, and graphical evidence was examined particularly closely. Output is the real GDP as calculated by the IMF's International Financial Statistics , house prices are expressed in real terms by deflating the nominal house price indices by CPI, credit is bank credit to the private sector deflated by CPI.1. The charts do suggest that stationarity is only achieved at the specified differenced series.2. The ERS test barely passes the confidence level. 3. Schwarz criterion suggests taking 3 lags and there is no SC either with 1 or 2 lags. Three lags suggest I(1).

Table 2. Variance Shares

Notes: The table reports the variance shares of common components for two alternative ways of data treatment - first differencing and filtering using the ideal band pass filter. The series included in this illustrative exercise are output, house prices, credit, short- and long-term interest rates. The last row shows the number of series, in percent of the total number of series, for which the variance share explained by the common components of the included series exceeds 20 percent.

Page 21: House Price Cycles and  the Real Economy

Credit and house price cycles tend to be slightly more protracted on average than business cycles... but peaks and troughs generally are not too far.

Credit and house price cycles have larger swings than real activity cycles).

In some countries, there are significant differences across these characteristics… Countries that allow MEW and refinancing tend to

have larger amplitude and longer duration in house price cycles relative to the business cycle if the share of variable rate mortgages is large (e.g., New Zealand versus Germany).

Characteristics of Cycles

Page 22: House Price Cycles and  the Real Economy

Characteristics of Cycles

Page 23: House Price Cycles and  the Real Economy

Financial accelerator model is not empirically supported in all countries—correlations vary in significance and sign.

Collateral is a driver of procyclicality more than lending is—stronger correlation between output and house prices than between output and bank credit.

Table 5. Correlation Coefficients for Total Cyclical Components

Notes: The table reports the correlation coefficients for the total cyclical component of output (real GDP), house prices, residential investment, and credit series, over the entire sample period. For each pair listed in the column title, entries in the table show the correlation between the series over the whole sample period. Correlation coefficients larger than 0.40 are deemed to be significant and are highlighted.

Page 25: House Price Cycles and  the Real Economy

A large share of common components drive the three cycles.

The share of the common component in GDP and in credit has increased over time.

The importance of common shocks and/or the speed of transmission of shocks has increased over time.

Table 7. Evolution of Cyclical Movements Driven by Common Components

Notes: The table reports the correlation coefficients for the total cyclical components (including the common and idiosyncratic component, as shown in Figure 2) and the common components (shown in Figure 4).

Output House Prices CreditResidential Investment

Page 30: House Price Cycles and  the Real Economy

During the minor cycle, house prices lead output and credit only in a few cases.

In the long run, there is some support for financial accelerator mechanism, but which channel? balance sheet improvements -> credit -> house prices or house prices -> creditworthiness -> credit

Short-term interest rates never lead house prices. House prices lead output, which in turn leads

credit.U.S. cycles lead the corresponding cycles in the

long run in most cases, and U.S. credit cycles lead only in the short run.

Table 6. Leads and Lags between Cycles within Countries

Source: Authors' estimates.Notes: The table reports the lead-lag relationship between pairs of series that are the focus of the analysis. Interest rates are nominal short-term rates. For each pair listed in the column title, entries in the table indicate whether the first variable leads or lags the second variable, or whether the relationship is contemporaneous, on average, over the frequency band. The numbers in the bottom indicate the percentage of countries with a given type of relation. Leads and lags are calculated using the approach suggested by Croux, Forni and Reichlin (2001).

Source: Authors' estimates.Notes: For each pair of countries and the variable, entries in the table indicate whether the cyclical component in the United States leads or lags the cyclical component in the respective country listed in the first column, or whether the relationship is contemporaneous, on average, over the frequency band. The numbers in the bottom indicate the percentage of countries with a given type of relation. Leads and lags are calculated using the approach suggested by Croux, Forni and Reichlin (2001).

Conclusions

House price cycles lead other cycles in the long run

Interest rates tend to lag other cycles at all horizons

Global factors are important for all cycles, especially for credit and real activity in the latter part of the sample period

U.S. leads other countries in all cycles

Similar conclusions from other research

A six-variable VAR: real GDP, private consumption, residential investment, CPI inflation, the nominal (short term) interest rate and real house prices. 20 countries, sample from 1986-2009.

House price shocks are identified with a Cholesky decomposition. In practice they look like “housing demand shocks” because they lead to a strong comovement between real house prices and residential investment. Alternative identification through sign restrictions.

VAR delivers average responses, but there could be asymmetries between house price booms and busts.

Policy Implications

Can a uniform policy prescription of taking into account asset prices in monetary policy making be made? It seems not, statistical properties of house prices vary across countries. In addition, some shocks to house price inflation are persistent.

The U.S. business, house price, and interest rate cycles tend to lead the respective cycles in other countries over all horizons and more so recently. Questions domestically-focused economic policies.
