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 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 general equilibrium monopolistic competition model in which wages, productivity, consumption diversity, and markups respond to trade integration. We structurally estimate the model and simulate the impacts of removing all trade barriers generated by the Canada–U.S. border. Firm...

We develop a new general equilibrium model of monopolistic competition with heterogeneous firms, variable demand elasticity and multiple asymmetric regions, in which trade integration induces wage and productivity changes. Using Canada-US interregional trade data, we structurally estimate a...

This paper offers a new mechanism to explain de-industrialisation in response to a price increase of the manufactured good. In our trade model, one sector (agriculture) is perfectly competitive while the other (manufacturing) is monopolistically competitive. Both industries use skilled and...

We analyze the effects of the unprecedented rise in trade between Germany and the East - China and Eastern Europe - in the period 1988 - 2008 on German local labor markets. Using detailed administrative data, we exploit the cross-regional variation in initial industry structures and use trade...

We investigate the causal impact of equity market liberalizations on sectoral export performance across 91 countries (1980 - 1997). The increased availability of external finance has boosted trade of industries that intensively use relationship-specific inputs, and lowered exports of industries...

We develop a theory of a firm in an incomplete contracts environment which decides on the complexity, the organization, and the global scale of its production process. Specifically, the firm decides i) how many intermediate inputs are simultaneously combined to a final product, ii) if the...
