|November 2019||A Theory of Economic Unions|
with Giacomo A. M. Ponzetto, Jaume Ventura: w26473
After decades of successful growth, economic unions have recently become the focus of heightened political controversy. We argue that this is partly due to the growth of trade between countries that are increasingly dissimilar. We develop a theoretical framework to study the effects on trade, income distribution and welfare of economic unions that differ in size and scope. Our model shows that political support for international unions can grow with their breadth and depth as long as member countries are sufficiently similar. However, differences in economic size and factor endowments can trigger disagreement over the value of unions between and within countries. The model is consistent with some salient features of the process of European integration and statistical evidence from survey d...

|February 2016||Globalization and Political Structure|
with Giacomo A.M. Ponzetto, Jaume Ventura: w22046
This paper develops a theoretical framework to study the interaction between globalization and political structure. We show that political structure adapts to expanding trade opportunities in a non-monotonic way. Borders hamper trade. In its early stages, the political response to globalization consists of removing borders by increasing country size. In its later stages, however, the political response to globalization is to remove borders by creating international unions, and this leads to a reduction in country size. Moreover, negotiation replaces war as a tool to ensure market access. These predictions are consistent with historical evidence on trade, territorial expansion and war.
|December 2012||Offshoring and Directed Technical Change|
with Daron Acemoglu, Fabrizio Zilibotti: w18595
To study the short-run and long-run implications on wage inequality, we introduce directed technical change into a Ricardian model of offshoring. A unique final good is produced by combining a skilled and an unskilled product, each produced from a continuum of intermediates (tasks). Some of these tasks can be transferred from a skill-abundant West to a skill-scarce East. Profit maximization determines both the extent of offshoring and technological progress. Offshoring induces skill-biased technical change because it increases the relative price of skill intensive products and induces technical change favoring unskilled workers because it expands the market size for technologies complementing unskilled labor. In the empirically more relevant case, starting from low levels, an increase in o...

|April 2010||Competing Engines of Growth: Innovation and Standardization|
with Daron Acemoglu, Fabrizio Zilibotti: w15958
We study a dynamic general equilibrium model where innovation takes the form of the introduction new goods, whose production requires skilled workers. Innovation is followed by a costly process of standardization, whereby these new goods are adapted to be produced using unskilled labor. Our framework highlights a number of novel results. First, standardization is both an engine of growth and a potential barrier to it. As a result, growth in an inverse U-shaped function of the standardization rate (and of competition). Second, we characterize the growth and welfare maximizing speed of standardization. We show how optimal IPR policies affecting the cost of standardization vary with the skill-endowment, the elasticity of substitution between goods and other parameters. Third, we show that the...
