The paper applies an equilibrium correction model to discuss impacts of monetary, labour and external factors on the German inflation. The approach presented is of eclectic character and allows for examination which variables representative for various inflation theories matter empirically when...

Specific ideas about the Fisher relation between real and nominal interest rates and more general ideas about the nature of the central bank's duty to support the financial system in times of crisis were important to the Monetarist re-assessment of the causes of the Great Depression and what...

Assessing the effects of monetary policy and wage bargaining on employment and inflation in the European Monetary Union (EMU), in the first step a Post-Keynesian competitive claims model of inflation with endogenous money is developed. In this model the NAIRU is considered to be a short-run...

This paper adopts the Impulse-Response methodology to understand inflation persistence. It has often been argued that existing models of pricing fail to explain the persistence that we observe. We adopt a common general framework which allows for an explicit modelling of the distribution of...

Macroeconomic data suggest that the New Keynesian Phillips curve is quite flat - despite microeconomic evidence implying frequent price adjustments. While real rigidities may help to account for the conflicting evidence, we propose an alternative explanation: if price markup/cost-push shocks are...

The present paper offers a careful description of empirical identification of possible multiple changes in regime. We apply recently developed tools designed to select between regime-switching models among a broad class of linear and nonlinear regression models and provide a discussion of the...

I summarize recent progress made in the literature on inflation dynamics. This has been a very productive area of research due to the development of the so-called New Keynesian model and the availability of new macroeconomic and microeconomic evidence. Nevertheless, a number of problems still...

Inflation and unemployment are central issues in macroeconomics. While progress has been made on these issues recently using models that explicitly incorporate search-type frictions, existing models analyze either unemployment or inflation in isolation. We develop a framework to analyze...

While risk selection within the German public health insurance system has received considerable attention, risk selection between public and private health insurers has largely been ignored. This is surprising since - given the institutional structure - risk selection between systems is likely...

This paper explores the relationship between risk attitude and asset diversification in household portfolios. We first examine the impact of manifested risk aversion on the total number of distinct assets held in a portfolio (naive diversification). The second part of the paper focuses on a more...
