Interstellar Economics
For those of you not subscribed to my Shared Items, here is some silly research on the economics of interstellar travel.
First Fundamental Theorem of Interstellar Trade: When trade takes plaec between two planets in a common inertial frame, the interest costs on goods in transit should be calculated using time measured by clocks in the common frame, and not by clocks in the frame of trading spacecraft.
Second Fundamental Theorem of Interstellar Trade: If sentient beings may hold assets on two plaents in the same inertial frame, competition will equalize the interest rates on the two planets.
