We study the implications of increased price flexibility on output volatility. In a simple DSGE model, we show analytically that more flexible prices always amplify output volatility for supply shocks and also amplify output volatility for demand shocks if monetary policy does not respond...

This paper studies optimal monetary policy under dynamic debt deleveraging once the zero bound is binding. Unlike the existing literature, the natural rate of interest is endogenous and depends on macroeconomic policy. Optimal monetary policy successfully raises the natural rate of interest by...

We propose an overlapping generations New Keynesian model in which a permanent (or very persistent) slump is possible without any self-correcting force to full employment. The trigger for the slump is a deleveraging shock, which creates an oversupply of savings. Other forces that work in the...

We consider the consequences for monetary policy of the zero floor for nominal interest rates. The zero bound can be a significant constraint on the ability of a central bank to combat deflation. We show, in the context of an intertemporal equilibrium model, that open-market operations, even of...

In previous work (Eggertsson and Woodford, 2003), we characterized the optimal conduct of monetary policy when a real disturbance causes the natural rate of interest to be temporarily negative, so that the zero lower bound on nominal interest rates binds, and showed that commitment to a...

This paper develops a model in which the rivalry of oligopolistic firms serves as an independent cause of international trade. The model shows how such rivalry naturally gives rise to "dumping" of output in foreign markets, and shows that such dumping can be "reciprocal" -- that is, there may be...

This paper argues that Japan's export growth is likely to slow sharply over the next few years, perhaps to zero. For the past dozen years Japan's export volume has gown much more rapidly than her domestic production. This divergence was made necessary primarily by rising oil prices, and...

The actual value added tax systems used in many countries differ significantly from the completely general VAT that has been the focus of most economic analyses. In practice, VAT systems exempt broad classes of consumer goods and services. This has important implications for the effect of the...

This paper reviews recent work on the relationship between industrial organization and international trade. Five strands in the theoretical literature are discussed. First is the role of economies of scale as a cause of intra-industry trade, modelled using monopolistic competition. Second is the...

This paper presents evidence strongly suggesting that the current strength of the dollar reflects myopic behavior by international investors; that is, that part of the dollar's strength can be viewed as a speculative bubble. At some point this bubble will burst, leading to a sharp fall in the...
