Sharing the burden: monetary and fiscal responses to a world liquidity trap
Devereux, Michael B.; Cook, David (2011)
With integrated trade and financial markets, a collapse in aggregate demand in a large country can cause "natural real interest rates" to fall below zero in all countries, giving rise to a global "liquidity trap." This paper explores the optimal policy response to this type of shock, when governments cooperate on both fiscal and monetary policy. Adjusting to a large negative demand shock requires raising world aggregate demand, as well as redirecting demand towards the source (home) country. ; The key feature of demand shocks in a liquidity trap is that relative prices respond perversely. ...

Exchange rate flexibility under the zero lower bound
Devereux, Michael B.; Cook, David (2014-09-01)
An independent currency and a flexible exchange rate generally helps a country in adjusting to macroeconomic shocks. But recently in many countries, interest rates have been pushed down close to the lower bound, limiting the ability of policy-makers to accommodate shocks, even in countries with flexible exchange rates. This paper argues that if the zero bound constraint is binding and policy lacks an effective ?forward guidance? mechanism, a flexible exchange rate system may be inferior to a single currency area. With monetary policy constrained by the zero bound, under flexible exchange ...

Dollar bloc or dollar block: external currency pricing and the East Asian crisis
Devereux, Michael B.; Cook, David (2004)
This paper provides a quantitative investigation of the East Asian crisis of 1997-99. The two essential features of the crisis that we focus on are a) the crisis was a regional phenomenon; the depth and severity of the crisis was exacerbated by a large decline in regional demand, and b) the practice of setting export goods prices in dollars (which we document empirically) led to a powerful internal propagation effect of the crisis within the region, contributing greatly to the decline in regional trade flows. We construct a model with these two features, and show that it can do a reasonable ...

Dual labor markets and business cycles
Nosaka, Hiromi; Cook, David (2006-06)
In this paper, we model a dynamic general equilibrium model of a small open developing economy. We model labor markets as including both formal and informal urban employment as well as rural employment. We find that modelling dual labor markets helps explain why output in developing economies may fall even as labor inputs remain constant during financial crises. An external financial shock may lead to a reallocation of labor from productive formal sectors of the economy to less productive informal sectors.

Dual labor markets and business cycles
