|February 2016||Globalization and Political Structure|
with Giacomo A.M. Ponzetto, Jaume Ventura: w22046
The first wave of globalization (1830-1914) witnessed a decline in the number of countries from 125 to 54. Political consolidation was often achieved through war and conquest. The second wave of globalization (1950-present) has led instead to an increase in the number of countries to a record high of more than 190. Political fragmentation has been accompanied by the creation of peaceful structures of supranational governance. This paper develops a theoretical model of the interaction between globalization and political structure that accounts for these trends and their reversal. We show that political structure adapts to steadily expanding trade opportunities in a non-monotonic way. Borders hamper trade. In its early stages, the political response to globalization consists of removing bord...
|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...
