가격상한제에 따른 초과수요와 후생손실에 대한 분석

초록

This study points out that the usual analysis of welfare losses under price ceilings in textbooks is based on the assumption that consumers with the highest willingness to pay receive the good, and suggests ways to improve it. We also identify upper and lower bounds for the welfare loss caused by excess demand under price ceilings, and analyze the average welfare loss when goods are allocated by lottery. Finally, we set up the excess demand situation as a game situation to find the Nash equilibrium and derive its welfare implication.
