This paper investigates the effects of fixed versus flexible exchange rate regimes on location choices of firms and on the degree of specialization of countries. In a two-country two-differentiated-good monetary model, demand, supply, and monetary shocks arise after wages are set and prices are...

There are various parametric models to analyse the volatility in time series of financial market data. For maximum likelihood estimation these parametric methods require the assumption of a known conditional distribution. In this paper we examine the conditional distribution of daily DAX returns...

In a recent paper, Homburg and Richter have argued that with free mobility of labor within a common labor market there is a need to harmonize and even consolidate pay-as-you-go financed national public pension systems to reach an efficient allocation of labor. We show that with free and...

This paper reexamines the Equity Premium Puzzle for the German stock market with control for inflation and taxation. Two methods for relaxing the assumption of aggregate consumption being equal to aggregate dividends are compared: the leverage approach and the usage of a bivariate stochastic...

A widely used method in the analysis of complex econometric models is to replace the "true model" by a highly simplified aggregative one in which the variables are grouped and replaced by sums or weighted averages of the variables in each group. The analysis of the problem of choosing an...

In a framework for risk management a model of an international firm under exchange rate uncertainty is discussed. The firm can cross-hedge the exchange rate risk by using forwards of other country's currencies correlated to the spot exchange rate in question. The study investigates the...

This paper constructs an intertemporal model of the spot and forward markets for foreign exchange and shows that in equilibrium the forward market is unbiased, i.e., the forward rate is equal to the expected spot rate which will prevail in the market next period. This holds true as long as the...
