Ölpreiskanäle in DSGE-Modellen -- Ölpreis, Arbeitslosigkeit und optimale Geldpolitik.-Ölpreisschocks und optimale Geldpolitik in kleinen Volkswirtschaften -- Endogener Ölpreis und Zentralbankkooperation in großen Volkswirtschaften. .

This study addresses the potential trade-off between inflation and exchange rate targeting in former transition countries, which now may be labeled emerging market economies and which prepare for entry into the Economic and Monetary Union (EMU). Among this group of countries, some implemented...

We present a comprehensive framework for Bayesian estimation of structural nonlinear dynamic economic models on sparse grids. The Smolyak operator underlying the sparse grids approach frees global approximation from the curse of dimensionality and we apply it to a Chebyshev approximation of the...

We present an object-oriented software framework allowing to specify, solve, and estimate nonlinear dynamic general equilibrium (DSGE) models. The implemented solution methods for finding the unknown policy function are the standard linearization around the deterministic steady state, and a...

This dissertation consists of three essays studying various issuesin international macroeconomics and macroeconomics.The first essay investigates the dynamics of the relative price ofnontradable to tradable goods at business cycle frequencies andfinds that it displays an emph{S}-shaped cross...

This paper examines how cooperation in an insurance game depends on risk preferences and the riskiness of income. It considers a dynamic game where commitment is limited, and characterizes the level of cooperation as measured by the reciprocal of the discount factor above which perfect risk...

Suppose we wish to carry out likelihood based inference but we solely have an unbiased simulation based estimator of the likelihood.  We note that unbiasedness is enough when the estimated likelihood is used inside a Metropolis-Hastings algorithm.  This result has recently been introduced in...
