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...

This paper explains a currency crisis as an outcome of a switch in how monetarypolicy 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...

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...

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

We give an explicit PDE characterization for the solution of the problemof maximizing the utility of both terminal wealth and intertemporal consumption under model uncertainty. The underlying market model consists of a risky asset, whose volatility and long-term trend are driven by an external...

This paper explores implications of nominal rigidity characterized by a non-constanthazard function for aggregate dynamics. I derive the NKPC under an arbitrary hazardfunction and parameterize it with the Weibull duration model. The resulting Phillips curveinvolves lagged inflation and lagged...

In semiparametric models it is a common approach to under-smooth the nonparametric functions inorder that estimators of the finite dimensional parameters can achieve root-n consistency. The requirementof under-smoothing may result as we show from inefficient estimation methods or technical...

This paper studies how dierent unionisation structures aect rm productivity, rmperformance, and consumer welfare in a monopolistic competition model with heterogeneousrms and free entry. While centralised bargaining induces tougher selection among hetero-geneous producers and thus increases...

In this paper we develop several regression algorithms for solvinggeneral stochastic optimal control problems via Monte Carlo. Thistype of algorithms is particularly useful for problems with a highdimensionalstate space and complex dependence structure of the underlyingMarkov process with...

Recent studies suggest that the correlation of stock returnsincreases with decreasing geographical distance. However, there is some debateon the appropriate methodology for measuring the effects of distanceon correlation. We modify a regression approach suggested in the literatureand complement...
