"The Theory of Interstellar Trade"

This article extends interplanetary trade theory to an interstellar setting. It is chiefly concerned with the following question: how should interest charges on goods in transit be computed when the goods travel at close to the speed of light? This is a problem because the time taken in transit will appear less to an observer traveling with the goods than to a stationary observer. A solution is derived from economic theory, and two useless but true theorems are proved.
And I'd like to think that most of p-kroog's columns for the NYTimes were likewise satirical. That would explain a great deal.
