Economists Paul Krugman published a theoretical paper examining how interstellar trade would function under relativistic physics constraints. Krugman applies classical economic models to scenarios where time dilation affects commerce between planets at different velocities.

The paper explores how special relativity impacts economic calculations for trade routes spanning light-years. Krugman demonstrates that traditional economic principles require modification when accounting for time perception differences between trading partners traveling at relativistic speeds.

This academic work bridges theoretical physics and economics, providing a framework for considering commerce in potential future interstellar civilizations. The paper highlights how fundamental economic concepts must adapt to operate within the constraints of our universe's physical laws.
