Paul Krugmans teori om interstellär handel



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 goods than to a stationary observer. A solution is derived from economic theory, and two useless but true theorems are proved."




1. Introduction


"...the assumtions underling neoclassic theory bear little resemblance to the world we know. These critics have however, been too quick to assert that this shows that mainstreams economics can never be of any use. (....) doubtful (...) we may eventually discover or construct a world to wich orthodox economic theory applies."


2.

(...) "It should be noted that, while the subject of this paper is silly, the analysis actually makes sense. This paper, then, is a serious analysis of a ridiculous subject, wich is of course the opposite of what is usual in economics. " (...)

Björn Nilsson sa...

Var det inte Sven Grassman som någon gång räknade ut att summan av Jordens alla länders samlade utlandsskulder inte blev noll som man skulle kunna tro, utan att det faktiskt var en nettoskuld? Den måste ju då vara till någon annan planet. Undrar hur den skulle reagera på hot om skuldnedskrivning eller till och med konkurs från Jorden - skulle det komma en massa arga tefats-gubbar och vifta med strålpistolerna?
