We analyze optimal social discount rates when people derive utility from relative consumption. We compare the social, private, and conventional Ramsey rates. Assuming a positive growth rate, we find that 1) the social discount rate exceeds the private discount rate if the importance of relative...

This paper analyzes optimal social discount rates where people derive utility from relative consumption. We identify and compare three separate discount rates: the social rate (taking positional externalities into account), the private rate, and the conventional Ramsey rate. Two main findings...
