> The theory of interstellar trade is a well-understood topic, with an extensive literature consisting of one paper (pdf) I wrote in 1978. Interstellar finance, however, is less well covered.
> That’s all about to change, however. I’m reading an advance copy of Charlie Stross’s Neptune’s Brood. (Hey, I have connections!) And it is the best thing by far written on the subject to date, partly because it is, as far as I know, the only thing written on the subject to date.
> 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. A solution is derived from economic theory, and two useless but true theorems are derived.
