Ø Quantitative Easing (QE) in developed countries (after GFC)
ü United States, United Kingdom, European Central Bank, Japan
ü Mixed results
• United States has ended QE program with improved economic
conditions.
• EU and Japan have been implementing QE program, but didn’t
achieve economic recovery yet.

u Japan’s Lost Decades
Ø Evaluation of the monetary policy of Bank of Japan
ü Zero interest rate policy from 1999 to 2000 failed to obtain market
confidence (Ugai, 2007).
ü Expansionary monetary policy had been effective, but limited due to
near-zero policy rate and deflationary pressure (Bayoumi, 2001).
ü QE had certain effect on the financial sector (for example, on long-term
yields), but its impact on real sector was quite limited (see, for example,
Schenkelberg and Watzka, 2013; Berkmen, 2012).
ü QE had positive effect on CPI, but the impact was small (Schenkelberg
and Watzka, 2013).

Ø Evaluation of the monetary policy of Bank of Japan (continued)
ü BOJ would have improved economic performance if it had targeted
higher inflation rate and reacted more aggressively to output (Leigh,
2010).
ü BOJ should make a credible commitment to fight deflation and escape
from liquidity trap (Krugman, 1998; Eggertsson and Woodford, 2003;
Svensson, 2003).
ü The effect of QE mainly came from expectations on interest rates, while it
was not sufficient to revive economy (Ugai, 2007).

Ø Forward guidance (Krugman, 1998; Eggertsson and Woodford; 2003,
Svensson, 2003; Woodford, 2012)
ü Forming expectations about future monetary policy is important.
ü Expectations affect economic decisions such as consumption and
investment through long-term interest rate even when the short-term
interest rate (such as policy rate) hits zero.
ü Simply lowering policy rates and increasing monetary base won’t alter
economic decisions unless people believe that the policy rate will be kept
low in the future (and long-run interest rates will fall).
ü Establishing confidence in private sector is important.

Ø Issue 1: QE really needed? (Sung, 2016)
ü Policy rate is 1.5% at the moment, hence there’s still room for traditional
monetary policy measure to boost economy.
ü More traditional policy tools including interest rate policies and
restructuring industries could be still the better solution.
ü Later, QE could be effective in resolving household debt problem as well
as corporate debt problem in Korea, both of which are considered as
huge challenges for Korean economy.

Ø Issue 2: QE Insufficient to fight deflation and achieve economic recovery
(Sung, 2016)
ü Credit rationing rather than QE:
• Advocates argue that the Bank of Korea (BOK) should direct money
into companies in financial distress through KDB.
• But, if BOK purchases bonds issued by KDB and MBS, then it will
lead to downward pressure on the interest rates.
• Then, BOK should absorb liquidity later to maintain policy rate at
1.5%. (Recall that federal funds rate was near zero, when Fed
purchased a large amount of long-term securities and MBS.)

(Sung, 2016) (continued)
ü As a result, BOK cannot change private sector’s expectations about future
monetary policy as Fed did (since it’s not accompanied by a credible
commitment), and hence cannot fight deflation and achieve economic
recovery.

Ø Policy suggestion (Sung , 2016)
1. Further lower policy rate.
2. Inject liquidity into the economy, not a specific sector or companies.
3. Stimulate consumption and investment by lowering long-term interest
rates.
4. Use forward guidance to fight deflation and achieve economic recovery.
