This paper first presents stylized evidence showing how the date of the adoption of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We then present a theoretical model with countries of different size, trade costs, and firms competing...

This paper analyzes whether complexity, measured by the number of skilled tasks that are performed in production, explains countries commodity trade structure. We modify the Romalis (<link/>) model to incorporate advantage differences in complexity across commodities together with differences in the...

Contrary to the prevailing interpretation, this paper shows that the central models of trade with heterogeneous firms (<link>Melitz 2003</link>; <link>Bernard et al. 2003</link>) exhibit ambiguous predictions for the exporter productivity premium. This prospect arises because of differences between theoretical and...

In this paper, we offer an explanation why globalization (falling trade costs) may increase the government incentive to block foreign takeover of domestic firms and increase its incentive to allow mergers among national firms. This creation of `national champions' occurs not only because the...

This study analyzes the impact of opening up markets on the diffusion of flexible manufacturing in a general equilibrium framework. With flexible manufacturing, suppliers can service a range of downstream industries and do not have to be concerned about being held up. Instead, the vertical...

Large distance and border effects on trade flows in some industries may result from the collusive division of geographic markets. In the Brazilian cement industry, traditional gravity equations fit the data well, yet limited regional flows are due to firms' strategic behaviour. Thanks to a...

Some cultural goods are consumed socially and are characterized by the same consumption network externalities as languages. Also, producers of new cultural goods in any one country draw on the stock of ideas generated by previous cultural production in all countries. For such goods, costless...

Recent trade models with heterogeneous firms have changed the interpretation of gravity equations. Chaney (2008) shows that the effect of distance on the number of exporters and average exports depends on key parameters characterizing the elements of market structure. We use firm-level export...
