Pat and Chris can spend their non-leisure time working either in the marketplace or at home (preparing dinner, taking care of children, doing repairs). In the marketplace, Pat earns a higher wage, w( = $20, than Chris, wC = $10. Discuss how living together is likely to affect how much each of them works in the marketplace. In particular, discuss what effect marriage would have on their individual and combined budget constraints and their labor-leisure choices (see Chapter 5). In your discussion, take into account the theory of comparative advantage?
