This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

We study a segmented-markets setting in which self-fulfilling volatility can arise. The only requirements are (i) asset price movements redistribute wealth across markets (e.g., equities rise as bonds fall) and (ii) some stabilizing force keeps valuation ratios stationary (e.g., cash flow growth...

Under conditions of risk it makes a difference whether the discount rate is determined as an expected present or as an expected future value. This difference which is dubbed as the Weitzman-Gollier puzzle has stimulated an intensive discussion which, however, is somewhat confusing. In this paper...

This paper challenges the common assumption of market segmentation in international trade. To analyze export entry and pricing decisions of firms in integrated vs. segmented markets, we develop a novel tractable approach based on stochastic export costs that allows us to compare firm-level and...

We study cross-country price differences in the European market for new passenger cars based on detailed pricing and technical data. Car prices in Europe converged until the year 2003, but not thereafter. Within the EU 15 countries the price range of the median model in 2004 was close to 20...

We consider a multi-service transportation system in which passengers are heterogeneous along two dimensions, namely ideal departure time and value of time, leading to both horizontal and vertical differentiation. We investigate the behavior of passengers, and assess how service pricing and...
