This chapter considers some extensions of matching models under transferable utility (TU). It begins with a discussion of preinvestment, in which agents deliberately invest in education, and the stock of human capital that characterizes them when entering the marriage market is therefore (at least partly) endogenous. It is safe to assume that agents, when deciding their investment, take into account, among other things, its impact on the marriage market. An alternative argument is that agents are likely to invest too much. The chapter proceeds by analyzing the relevance of TU to risk sharing, multidimensional matching, and the roommate matching problem, taking into account the existence of a stable matching and the cloned bipartite problem. Finally, it describes the basic model of divorce and remarriage, focusing on compensations in the Becker-Coase theorem as well as violations of the theorem.
