4.3 Pat and Chris can spend their nonleisure 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, wp = $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 the marriage has on their individual and combined budget constraint

(Chapters 4 and 5) and their labor-leisure choice

(Section 5.5, “Deriving Labor Supply Curves”). In your discussion, take into account the theory of comparative advantage.
