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...

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...

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...

Response time has been regarded as an important source for investigating the relationship between human performance and response speed. It is important to examine the relationship between response time and item characteristics, especially in the perspective of the relationship between response...

In many studies, lattice or area data are observed and spatial analysis is performed. A spatial process observed over a lattice or a set of irregular regions is usually modeled using a conditionally autoregressive (CAR) model. The neighborhoods within a CAR model are generally formed using only...
