In the classical Arrow-Borch-Raviv problem of demand for insurance contracts, it is well-known that the optimal insurance contract for an insurance buyer – or decision maker (DM) – is a deductible contract, when the insurer is a risk-neutral Expected-Utility (EU) maximizer, and when the DM...

This paper explores the effect of moral hazard on both risk-taking and informal risk-sharing incentives. Two agents invest in their own project, each choosing a level of risk and effort, and share risk through transfers. This can correspond to farmers in developing countries, who share risk and...

Insurers have the reputation of being bad payers who nitpick when- ever an opportunity arises. However, this nitpicking activity has a positive impact on their auditing strategy since auditing may prove profitable when claims are not fraudulent. We show that reducing the indemnity payments of...

We construct a fully specified extensive form game that captures competitive markets with adverse selection. In particular, 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...

The purpose of this paper is to challenge the conventional theory of moral hazard and adverse selection. Moral hazard and adverse selection problems in contemporary economic theory are plagued with four major aws: 1) the alleged asymmetrical information between buyer and seller as a problem in...

Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. An efficient risk classification system generates premiums that fully reflect the...

Guaranteed renewability is a prominent feature in many health and life insurance markets. It is well established in the literature that, when there is (only) risk type uncertainty, the optimal GR contract with renewal price set at the actuarially fair price for low risk types provides full...

We consider the traditional model of an insurance market that consists of high-risk and low-risk individual customers who are identical except for their accident probabilities. Though insurers know the values of the high-risk and low-risk accident probabilities, each individual customer’s...

This paper examines uberrimae fidei (utmost good faith) with adverse selection in an insurance market. If consumers know their risk type (they know their expected loss), and if they understand the concept of uberrimae fidei, adverse selection is completely eliminated. However, if uberrimae fidei...

One of the major contract innovation in liability insurance during the liability crisis of the early 1980s was the introduction of claims-made and reported insurance contracts. Typical insurance contracts are based on loss occurrence (i.e., occurrence-based contracts), which means that a loss...
