But t

34、rade surpluses continued to cumulate. Reason: Exchange rate changes only determine domestic inflation or deflation, not trade balance. The simple-minded elasticities approach (Marshall-Lerner condition) to determining the trade balance is invalid in financially open economies. McKinnon and Ohno 1997

35、 The story of Japan (II) Negative risk premium Goyal and McKinnon 2003 To maintain portfolio balance, Japanese financial institutions demand a higher return on dollars (which is riskier given the volatility in exchange rate). But the interest rate on dollar assets is determined internationally. Thus

36、 the interest rate on yen assets was forced down leading to a zero interest liquidity trap by the end of 1996. Is China like Japan? China has a big advantage over Japan: The RMB exchange rate has been, and can be, more credibly maintained at the current level without disturbing domestic price level.

37、 And a disadvantage: Chinas net FDI inflows are much larger than Japans. FDI can be seen as illiquid liabilities but adds to liquid dollar claims.
