The Theory of Interstellar Trade · 2008-03-17

Paul Krugman, author of well known works on trade theory, wrote quite cheerful stuff in his early days: Theory of Interstellar Trade. Here is the abstract:

This paper 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 travelling with the good than to a stationary observer. A solution is derived from economic theory, and two useless but true theorems are proved.

Great ... Economics, is there more science we possibly need?
