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...

The dissertation studies the relationship among durable goods, price indexes andmonetary policy in two sticky-price models with durable goods. One is a one-sectormodel with only durable goods and the other is a two-sector model with durable andnon-durable goods.In the models with durable goods,...

Wie sollten Zentralbanken Geldpolitik gestalten und der Öffentlichkeit kommunizieren, um die Ökonomie bestmöglich zu stabilisieren? Diese Dissertation, bestehend aus drei selbständigen Essays in dynamischer Makroökonomik, widmet sich in erster Linie dem normativen Aspekt von Geldpolitik....

Diese Doktorarbeit untersucht drei Fragestellungen. Erstens, wie die Wirkung von plötzlichen Änderungen exogener Faktoren auf endogene Variablen empirisch im Allgemeinen zu bestimmen ist. Zweitens, welche Effekte eine Erhöhung der Staatsausgaben im Speziellen hat. Drittens, wie optimale...

Chapter 1: Optimal Long-Run Inflation with Occasionally-Binding Financial Constraints.This paper studies the optimal inflation rate in a simple New Keynesian model with occasionally-binding collateral constraints that intermediate-good firms face on hiring labor. For empirically-relevant degrees...

Incluye un apéndice en línea ; Los modelos de mercados incompletos con agentes heterogéneos están cobrando especial relevancia en los análisis de políticas económicas. En este documento proponemos una nueva metodología para resolver problemas de políticas dinámicas óptimas, tanto...

La investigación empírica sugiere que los tipos de interés más bajos inducen a los bancos a asumir mayores riesgos. Analizamos lo que este canal de toma de riesgos implica para la política monetaria óptima en un modelo neokeynesiano manejable. Mostramos que este canal crea un motivo para...

Intertemporal general-equilibrium models with Keynesian features such as imperfect competition and imperfectly flexible prices which give rise to a (at least) short-run non-neutrality of monetary policy have become the workhorse model for monetary macroeconomics. This thesis now makes four...

In this paper, I develop and estimate a dynamic model of strategicnetwork formation with heterogeneous agents. The main theoretical resultis the existence of a unique stationary equilibrium, which characterizesthe probability of observing a specific network in the data. As aconsequence, the...

Dynamic factor models (DFM) and dynamic stochastic general equilibrium (DSGE) models are widely used for empirical research in macroeconomics. The empirical factor literature argues that the co-movement of large panels of macroeconomic and financial data can be captured by relatively few common...
