Firm's inability to monitor employees search efforts results in a tradeoff between risk-bearing and incentive considerations in the design of employment-related insurance. Since the provision of insurance against firm-specific shocks adversely affects workers' incentives to search out better...

This paper shows that, except in certain limiting cases, competitive equilibrium with moral hazard is constrained inefficient. The first section compares the competitive equilibrium and the constrained social optimum in a fairly general model, and identifies six types of market failure. Each of...

The central result of this paper is that when moral hazard is present, shadow prices in general differ from market prices. To remedy this market failure, the government should introduce differential commodity taxation. Moral hazard causes people to take too little care to prevent accidents. The...

This paper examines the existence and properties of competitive equilibrium in economies with moral hazard. The nature of competitive equilibrium depends on whether insurers can observe an insured's total purchases of insurance. If insurers can observe this, an individual will purchase all his...

This paper is the first in a series. Among the results are: 1) Indifference curves between premiums and payouts are not generally quasi-concave; as a result the price- and income-consumption lines are generally not continuous; 2) Accident prevention effort is generally not continuous or monotonic...

A multi-period, general equilibrium labour market model is developed where risk-averse workers face job-related uncertainty and labour turnover is costly. If a worker is unlucky and suffers a bad match, he quits and joins another firm. We assume that the quality of a job match is unobservable; as...

Firms' inability to monitor their employees' search effort forces a tradeoff between risk-bearing and incentive considerations when designing employment-related insurance. Since the provision of insurance against firm-specific shocks adversely affects workers' incentives to find better jobs, the...

This paper examines the existence and nature of competitive equilibrium with moral hazard. The more insurance an individual has, the less care will he take. Consequently, insurance firms attempt to restrict their clients' aggregate insurance purchases. If individuals' aggregate insurance...

In this paper we investigate the descriptive and normative properties of competitive equilibrium with moral hazard when forms offer "price contracts" which allow clients to purchase as much insurance as they wish to at the quoted price. We show that a price equilibrium always exists and is one...
