A Game Theoretic Foundation of Competitive Equilibria With Adverse Selection

Abstract: We construct an extensive form game that captures competitive markets with adverse selection. It allows firms to offer any finite set of contracts, so that cross‐subsidization is not ruled out. Moreover, firms can withdraw from the market after initial contract offers have been observed. We show that a subgame perfect equilibrium always exists. In fact, when withdrawal is costless, the set of equilibrium outcomes may correspond to the entire set of feasible contracts. We then focus on robust equilibria that co… Show more

“…If the RS equilibrium does not exist, the MW contracts include a cross subsidisation from the low risk to the high-risk type. As our set-up is not exactly the same as in Netzer and Scheuer (2014), we prove these results for our set-up in the online Appendix. 17 The question is: does this characterisation of the 'perfect competition' outcome allow for q h \ 1?…”

“…When the only separating equilibrium is broken by a pooling contract, an RS equilibrium does not exist. Wilson (1977) (also Miyazaki, 1977Spence, 1978;Netzer and Scheuer, 2014) offers a slightly different model of perfect competition in an insurance market where equilibrium always exists. The main difference between RS and Wilson (1977) is that Wilson uses an equilibrium notion where every firm expects that all contracts that become unprofitable due to the firm's offered contracts will be withdrawn immediately.…”
