Working Papers

"The Gravity Equation in International Trade: an Explanation"
Big firms export faraway. 
Whether distance affects aggregate trade or not depends on whether there are many big firms or not. 
If the distribution of firm sizes is approximately Zipf, then aggregate trade is inversely proportional to geographic distance.

"Liquidity Constrained Exporters"
July 2005 | [PDF] | [NBER WP19170]
If firms face fixed export costs, then liquidity constraints may prevent a firm from exporting: the health of its balance sheet matters for exporting. 
A currency devaluation hurts domestic firms balance sheets, and may hurt aggregate exports despite its pro-competitive effect.

"Productivity Overshooting:
The Dynamic Impact of Trade Opening with Heterogeneous Firms"
June 2005 [PDF]
When trade barriers are high, (too) many firms can survive, sheltered from foreign competition. 
After a trade liberalization, it takes a long time for those firms to exit. 
The economy may overheat for a while.

"Technological Mismatch: a Model of International Trade in Goods and Ideas"
May 2008 | [PDF]
Some people are good at inventing new technologies, and some at implementing them. Both don't always live in the same country.
When international trade in ideas is allowed, talented inventors team up with talented craftsmen, world production and world trade go up.
