We consider a dynamic three-stage game played by two regulator-firm hierarchies to capture the scale and technological effects of opening markets to international trade. Each firm produces one good sold on the market. Firms can invest in R&D in order to lower their fixed emission/output ratio...

This paper investigates the interplay of trade and terrorism externalities under free trade between a developed nation that exports a manufactured good to and imports a primary product from a developing nation. A terrorist organization targets both nations and reduces its attacks in response to...

The Great Recession, which was preceded by the financial crisis, resulted in higher unemployment and inequality. We propose a simple model where firms producing varieties face labor-market frictions and credit constraints. In the model, tighter credit leads to lower output, lower number of...

This paper studies the effect of capital controls on misallocation and welfare in an economy with financial constraints. We build a general equilibrium model with heterogeneous firms, financial constraints and international trade and calibrate it to the Chilean economy. Since high-productivity...

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...

This paper analyzes the effect of trade liberalization on government spending in a general equilibrium model with a continuum of industries supplying tradable and nontradable goods under monopolistic competition. Trade liberalization is modeled as the opening up of product markets between two...

This paper investigates empirically the effect of import diversity on government size and provides evidence for the love of variety effect on government spending described in Hanslin (2008). I argue that crowding out of firms is an important cost of public good provision. However, due to the...
