We develop a general equilibrium model of vertical innovation in which multiple firms compete monopolistically in the quality space. The model features many firms, each of which holds the monopoly to produce a unique quality level of an otherwise homogenous good, and consumers who are...

With the help of a simple Ricardian model, this paper explores the role of industrial policy in self-enforcing trade agreements. A first part shows that the optimal self-enforcing trade agreement includes subsidies to inefficient, import-competing sectors. Second, when by some exogenous or...

Exporting firms do not only decide how much of their products they ship abroad but also at which frequency. Doing so, they face a trade-off between saving on fixed costs per shipments (by shipping large amounts infrequently) and saving on storage costs (by delivering just in time with small and...

We document that in the European car industry, exchange rate pass-through is larger for low than for high quality cars. To rationalize this pattern, we develop a model of quality pricing and international trade based on the preferences of Musa and Rosen (1978). Firms sell goods of heterogeneous...

The Euro Crisis has stopped the process of the European financial integration and triggered a strong repatriation of debt from foreign to domestic investors. We investigate this empirical pattern in light of competing theories of cross-border portfolio allocation. Three empirical regularities...

Cross-country variation in average retirement age is usually attributed to institutional differences that affect individuals' incentives to retire. We suggest a different approach. Since workers in different occupations naturally retire at different ages, the composition of occupations within an...
