In recent years, New Keynesian dynamic stochastic general equilibrium (NK DSGE) models have become increasingly popular in the academic literature and in policy analysis. However, the success of these models in reproducing the dynamic behavior of an economy following structural shocks is still...

Recent research has found that the dynamic properties of the New Keynesian model can be very different when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity, and the size of the government purchase output multiplier can be...

Recent research has found that the dynamics of the New Keynesian model are very different when the nominal interest rate is zero. Improvements in technology shocks and reductions in the labor tax rate lower economic activity and the size of the government purchase multiplier can be as large as...

We study how real exchange rate dynamics are affected by monetary policy in dynamic, stochastic, general equilibrium, sticky-price models. Our analytical and quantitative results show that the source of interest rate persistence - policy inertia or persistent policy shocks - is key. When the...

According to the two-country full information New Keynesian model with flexible exchange rates, the real exchange rate appreciates in response to an asymmetric negative demand shock at the zero lower bound (ZLB) and exacerbates the adverse macroeconomic effects. This finding requires inflation...

This paper addresses analytical aspects of exchange rate policy and emphasizes the relationship among exchange rate flexibility, financial discipline, and international competitiveness.

Upon entry into the European Union, countries become members of the Economic and Monetary Union (EMU), with a derogation from adopting the euro as their currency (that is, each country joining the EU commits to replace its national currency with the euro, but can choose when to request...

This study analyzes key issues associated with large increases in aid, including absorptive capacity, Dutch disease, and inflation. The authors develop a framework that emphasizes the different roles of monetary and fiscal policy and apply it to the recent experience of five countries: Ethiopia,...

Since the turn of the century, aid flows to Africa have increased on average and become more volatile. As a result, policymakers, particularly in post-stabilization countries where inflation has only recently been brought under control, have been increasingly preoccupied with how best to deploy...

This paper documents the specification of a model that was constructed to assess debt sustainability in emerging market economies. Key features of the model include external and fiscal sectors, which allow assessment of external and public debt in a unified framework; public and external debt,...
