We examine whether and how rainfall shocks affect tariff setting in the agricultural sector. In a model of international oligopoly, we show that the impact of a negative rainfall shock on optimal import tariffs is generally ambiguous, depending on the weight placed by the domestic policy maker...

This paper develops a two-country, general equilibrium model of oligopoly in which the degree of horizontal product differentiation is endogenously determined by firms' strategic investments in product innovation. Consumers seek variety and product innovation is more skill intensive than...

We examine whether and how rainfall shocks affect tariff setting in the agricultural sector. In a model of strategic trade policy, we show that the impact of a negative rainfall shock on optimal import tariffs is generally ambiguous, depending on the weight placed by the domestic policy maker on...

We analyse - theoretically and empirically - how private versus public ownership of firms affects the degree of rent sharing between firms and their workers. Using a particularly rich linked employer-employee dataset from Portugal, covering a large number of corporate ownership changes across a...

In a spatial competition setting there is usually a non-negative relationship between competition and quality. In this paper we offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key assumptions, namely that the providers are motivated and...

We study the effect of competition on quality in markets such as health care, long-term care and education, when providers choose both prices and quality in a setting of spatial competition. We offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key...

We analyse the dynamics and evolution of the corporate restructuring process in the Portuguese banking sector, where 10 banks were privatised during the period 1989–1996. We apply a novel methodological approach in this context, using a multidimensional measure of restructuring that links...

We study the relationship between competition and quality within a spatial competition framework where firms compete in prices and quality. We generalise existing literature on spatial price-quality competition along several dimensions, including utility functions that are non-linear in income...
