We analyze the equilibrium and the optimal resource allocations in a monocentric city undermonopolistic competition. Unlike the constant elasticity of substitution (CES) case, wherethe equilibrium markups are independent of the city size, we present a variable elasticity ofsubstitution (VES)...

We develop a model of commodity tax competition with monopolistically competitive internationallymobile firms, transport costs, and asymmetric country sizes. We investigate the impacts of noncooperativetax setting, as well as of tax harmonization and changes in the tax principle, in both...

We distill the main insights from recent trade models on firms' responses toglobalization. Our primary aim is to assess the economic impact and the welfareimplications of the resulting reallocation of resources across frims and countries. In sodoing, we bring theory into life through the...

We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...
