The standard two-country model of international trade with monopolistic competition predicts a more-than-proportional relationship between a country's share of world production of a good and its share of world demand for that same good, a result known as the home market effect. We first show...

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a novel framework to address this question at three...

We develop a general equilibrium model of monopolistic competition with a traded and a non-traded sector. Using a broad class of homothetic preferences—that generate variable markups, display a simple behavior of their elasticity of substitution, and nest the ces as a limiting case—we show...

We develop a new general equilibrium monopolistic competition model with variable demand elasticity, heterogeneous firms, and multiple asymmetric regions. Wages, productivity, consumption diversity, and markups across firms and markets are all endogenously determined and respond to trade...

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

We study the impact of transfer pricing rules on sales prices, firms’ organizational structure, andconsumers’ utility within a two-country monopolistic competition model featuring source-basedprofit taxes that differ across countries. Firms can either become multinationals, i.e., they serve...

We investigate the role of the transport sector in structuring the location of economic activitywithin two-region economic geography models of the footloose capital and core-peripherytypes. In our setting, competitive carriers offer transport services for shipping manufacturedgoods across...

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...
