"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.

A currency devaluation hurts domestic firms balance sheets, and may hurt aggregate exports despite its pro-competitive effect.

The economy may overheat for a while.
