In the data, individual prices change frequently and by large amounts. In standard sticky price models, frequent and large price changes imply a fast response of the aggregate price level to nominal shocks. This paper presents a model in which price setting firms optimally decide what to...

In recent policy debates some have argued that expansionary monetary policy in Japan can increase real output in Japan and in Japan's neighbors, while others have warned that it is a beggar-thy-neighbor policy. In this paper we estimate structural vector autoregressions to assess the effects of...

We decompose by origin the sources of the variation in real aggregate output and aggregate price level in the Czech Republic, Hungary and Poland. We find that a sizable fraction of the variation is attributable to external shocks, especially so for aggregate price level. We show that euroarea...

This paper explains a currency crisis as an outcome of a switch in how monetary policy and fiscal policy are coordinated. The paper develops a model of an open economy in which monetary policy starts active, fiscal policy starts passive and, in a particular state of nature, monetary policy...

Using structural VARs, I find that external shocks are an important source of macroeconomic fluctuations in emerging markets. Furthermore, U.S. monetary policy shocks affect quickly and strongly interest rates and the exchange rate in a typical emerging market. The price level and real output in...

Micro data on inflation expectations has two important properties: (i) there is substantial heterogeneity in inflation expectations across households, and (ii) the average inflation expectation responds slowly to shocks to actual inflation. This paper studies the effect of dispersed inflation...

Decision-makers often face limited liability and thus know that their loss will be bounded. We study how limited liability affects the behavior of an agent who chooses how much information to acquire and process in order to take a good decision. We find that an agent facing limited liability...

In this paper, we provide an outlook for further research on the topic of governance. We review four different approaches on the theory of the firm and discuss implications for governance, namely; nexus of contracts / agency theory, property rights /incomplete contracts, adaptation, and nexus of...

Recently, Diebold and Li (2003) obtained good forecasting results foryield curves in a reparametrized Nelson-Siegel framework. We analyze similarmodeling approaches for price curves of variance swaps that serve nowadaysas hedging instruments for options on realized variance. We consider the...

Here we develop methods for e±cient pricing multidimensional discrete-time American and Bermudan options by using regression based algorithms together with a new approach towards constructing upper bounds for the price of the option...
