Interest rates at the speed of light

Abstract: This paper extends interplanetary trade theory to an interstellar setting. It is chiefly concerned with the following question: how should interest rates 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...

An economist with a sense of humour! Now I've seen everything. ;)

"All you have to do to pay for a visit to The Restaurant at The End of the Universe is deposit one penny in a savings account in your own era, and when you arrive at the End of Time the operation of compound interest means that the fabulous cost of your meal has been paid for.

This, many claim, is not merely impossible but clearly insane, which is why the advertising executives of the star system of Bastablon came up with this slogan: "If you've done six impossible things this morning, why not round it off with breakfast at Milliways, the Restaurant at the End of the Universe?"

Instructions for manufacturing most items will probably be sent instead of the items themselves. If they can't replicate living things then tissue samples can be sent for cloning purposes. The only costs will be shipping or transmission of information. The products will cost nearly nothing. I don't foresee cargo ships flying from star to star, although I suppose the extremely rich might want rare imported items to show to their friends.

...I didn't even know there was an interplanetary trade theory. You learn something new every day here!
