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.
Liquidity Constrained Exporters
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%.
Productivity Overshooting:The Dynamic Impact of Trade Opening with Heterogeneous Firms
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.
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.
