Paul Krugmans Theory of Interstellar Trade

Ich hatte grade meinen Spaß mit Paul Krugmans Wirtschaftstheorie vom interstellaren Handel bei Lichtgeschwindigkeit: The Theory of Interstellar Trade (PDF). Das Teil ist von vorne bis hinten mit SciFi-Anspielungen gespickt – Krugman hat das Vorwort der Neuauflage von Asimovs Foundation geschrieben – und schließt mit den Worten: „Those of us working in this field are still a small band, but we know that the Force is with us.“ Hell, yeah!

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 goods than to a stationary observer.
