An Economic Justification for Gay Marriage
Tuesday, October 24th, 2006It’s clear that the debate over gay marriage is very hot in the US right now. However, it’s been mostly confined to moral grounds. Why don’t we look at it from an economic perspective?
This argument does not discuss calling the union of two homosexual individuals a “marriage” versus a “civil union.” I will save that argument for another time.
[Note: much of sections 2-3 are drawn from:
Dnes, Antony W. The Economics of Law. Mason, OH: Thomson Corporation, 2005. 189-204.
and inspired by lectures from classes I have taken at William & Mary. ]
I. Comparative Advantage and Specialization
First I would like to introduce the concept of gains from trade. Assume there are two countries and only two goods in the world. Country A can produce either ten footballs in an hour or five cars in that hour. Country B can produce seven footballs in an hour or six cars in an hour. If these countries decide to fill their needs without trade, they will need to divide their labor between footballs and cars. However, if they decide to trade, then each country can specialize in what it does best, and there will be more total footballs and cars in the world than if the countries did not trade.
