This Paper considers monetary and exchange rate policy in Korea since the financial crisis of 1997-98. The Bank of Korea has adopted much of the apparatus of inflation targeting, with a band for target inflation and a Monetary Policy Report to the National Assembly. This regime has served the...

We consider a dynamic stochastic model of currency attacks, characterised by imperfect information about the fundamental. Agents, who imperfectly know the state of the economy, not only decide whether to attack the peg, but also formulate expectations concerning the probability of future...

The assertion that a flexible exchange rate regime would facilitate current account adjustment is often repeated in policy circles. In this paper, we compile a data set encompassing data for over 170 countries over the 1971-2005 period, and examine whether the rate of current account reversion...

The discomfort a government suffers from speculation against its currency determines the strategic incentives of speculators and the scope for multiple currency-market equilibria. After describing an illustrative model in which high unemployment may cause an exchange rate crisis with...

This paper surveys the evidence on the effectiveness of monetary transmission in developing countries. We summarize the arguments for expecting the bank lending channel to be the dominant means of monetary transmission in such countries, and present a simple model that suggests why this channel...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

This Paper explores the quantitative implications of an approach to monetary policy that gained prominence in the United States during the 1990s. Proponents of this approach recommend that, when inflation is moderate but still above the long-run objective, the central bank should not move...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...

Inflation-targeting central banks have only imperfect knowledge about the effect of policy decisions on inflation. An important source of uncertainty is the relationship between inflation and unemployment. This Paper studies the optimal monetary policy in the presence of uncertainty about the...

Most central banks perceive a trade-off between stabilizing inflation and stabilizing the gap between output and desired output. However, the standard new Keynesian framework implies no such trade-off. In that framework, stabilizing inflation is equivalent to stabilizing the welfare-relevant...
