This paper investigates the relationship between various market imperfections and the skill premium. The model in this paper assumes perfectly competitive labor markets but distorted product and financial markets. The model predicts that the skill premium is positively correlated with market...

This paper lays out and elaborates upon the properties of an extended Chamberlinian model with applications both in Industrial Organization and Economic Geography/ Urban Economics. The framework is used to explain the impact of some major changes over the last two centuries: reductions in...

Real-world industries are composed from heterogeneous firms and substantial intra-industry reallocations take place, i.e. high productivity firms squeeze out low productivity firms. Previous tax-tool comparisons have not included these central forces of industry structure. This paper examines a...

This paper is motivated by the empirical regularity that industries differ greatly in the level of firm turnover, and that entry and exit rates are positively correlated across industries. Our objective is to investigate the effect of sunk costs and, in particular, market size on entry and exit...

We introduce a framework that has known models of oligopolistic competition with differentiated products (the circle and the constant elasticity of substitution (CES)) as limit cases. This integrative approach incorporates both localized and global competition, as well as price-sensitive...

We study when a monopolistically-competitive firm may optimally choose to limit the size of its market. This may be the case when the cost of serving the market with geographically dispersed customers is increasing in size. We also investigate the incentives faced by a firm to limit the reach of...

A two sectors, two regions economy, where one sector is perfectly competitive and the other is monopolistically competitive, is considered. The region hosting more firms in the monopolistic sector produces at alower marginal cost (or equivalently produces varieties more intensely demanded by...

We develop a model of monopolistic competition that accounts for consumers’ heterogeneity in both incomes and preferences. This model makes it possible to study the implications of income redistribution on the toughness of competition. We show how the market outcome depends on the joint...
