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 distance.

When the value of a firm's real estate appreciates, the firm invests and hires new workers.
This real estate collateral channel can explain 10% of the aggregate investment and employment growth in France over 2002-2006.
Lifting the collateral constraint for all firms would increase aggregate welfare by 4% and the total wage bill by 2%.

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:

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.
