This paper studies the co-movements of unemployment and labor productivity growth for the U.S. economy. Measures of co-movements in the frequency domain indicate that co-movements between variables differ strongly according to the frequency. First, long-term and business cycle co-movements are...

This paper considers a two-period optimal contracting model in which firms make new hires in the second period subject to the constraint that they cannot pay discriminate either against or in favor of the new hires. Under an assumption on the information available to workers, it is shown that...

This paper develops a dynamic monopolistic competition model with heterogenous firms to analyze the effects of uncertainty on international trade. We characterize a stationary equilibrium, with N symmetric countries, where firms’ productivities evolve stochastically over time. Our model...

This paper presents the first empirical test with German establishment level data of a hypothesis derived by Helpman, Melitz and Yeaple in a model that explains the decision of heterogeneous firms to serve foreign markets either trough exports or foreign direct investment: only the more...

This paper analyses the relationship between firm productivity and export behavior in German manufacturing firms. We examine whether productivity increases the probability of exporting, and assert that there is a causal relationship from high productivity to entering foreign markets, as...

This paper investigates one reason why some countries have experienced a strong increase in wage inequality over the last decades while others have not. The explanation is based on the link between the quality of education and induced technological change. A country with qualitatively...

We develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts. We show that an improvement in the employment status of either an agent's direct or indirect contacts leads to an increase in the agent's employment probability...

Removal of tariff restrictions from the relatively low-skill sectors; growth in foreign direct investment; and, decline of trade union strength of the unskilled workers are cited in the empirical literature as the prime factors responsible for the growing incidence of wage inequality in many of...

The paper is purported to analyze the impact of skill formation on the skilled-unskilled wage inequality using a few variants of the HOS-type framework. It shows that the effect of skill formation on the wage inequality depends crucially upon the technologies of production of the economy and...
