We build a simple dynamic model to investigate the sequential group lending's ability to resolve the ex-ante moral hazard and under-monitoring problems among group members in comparison with simultaneous group lending. We found that the interest rates proposed by the lender are critical to the analytical results. If the interest rate is under certain parameter conditions, both the leader member...

Not only does economic theory predict high-risk individuals to be more likely to purchase insurance, but insurance coverage is also thought to crowd out precautionary activities. In spite of stark theoretical predictions, there is conflicting empirical evidence on adverse selection, and evidence on ex ante moral hazard is very scarce. Using data from the Seguro Popular Experiment in Mexico, thi...

We study the agency costs of delegated public service provision, focusing on the link between organizational forms and uncertainty at project implementation. We consider a dynamic multitask moral hazard environment where the mapping between effort and performance is ex ante uncertain but new information may arise during operations. Our analysis highlights the costs and benefits that bundling pl...

Accounting for unreported accidents due to ex post moral hazard is important for studying asymmetric information in insurance markets. In this paper, I study ex post moral hazard in an automobile insurance market with experience rating. I develop a dynamic model in which policyholders with private information about their risk types choose accident prevention efforts (ex ante moral hazard) and m...

Existence of pure strategy equilibria is studied in health insurance markets that exhibit both ex ante adverse selection of the Rothschild–Stiglitz–Wilson type, and ex post hidden information moral hazard. It is found that ex post moral hazard has two offsetting effects on the existence of equilibrium, and that in general it is difficult to say whether an equilibrium is more or less likely to e...

Bank crises, by interrupting liquidity provision, have been viewed as resulting in welfare losses. In a model of banking with moral hazard, we show that second best bank contracts that improve on autarky ex ante require costly crises to occur with positive probability at the interim stage. When bank payoffs are partially appropriable, either directly via imposition of fines or indirectly by the...

Under certain conditions the optimal insurance policy will offer full coverage above a deductible, as Arrow and others have shown long time ago. Interestingly, the same design of insurance policies applies in case of a single loss and ex-ante moral hazard. However, many insurance policies provide coverage against a variety of losses and the possibilities for the insured to affect the probabilit...

This Panel Paper reviews recent evidence on moral hazard in the insurance industry. We discuss three types of moral hazard and detail how each is an asymmetric information problem. For each of the types, we summarize the empirical evidence and discuss the policy implications that follow from it. The evidence for ex ante moral hazard (i.e., insurance-induced increases in risk-taking) is rather w...
