Rothschild and Stiglitz (1976) demonstrated that adverse selection may entail nonexistence of equilibrium in competitive insurance markets. We approach this problem in a dynamic model with boundedly rational insurance rms. Firms' behavior is based on imitation of pro t making contracts, withdrawal of loss making contracts, and experimentation with random contracts. Consumers choose in each peri...

governmental contracts have an important place in the financial and economic system.because the transfer of funds generally is done by contracts. in other hand because of governmental economic system in our country and concentration of capital in this section, the governmental contracts has greater importance.therefore the special monitoring on various stages of contract from foundation to impl...

This paper presents preliminary findings from a research project that examines the interaction between informal risk sharing, index insurance and risk-taking. We have randomized rainfall insurance contracts offered to cultivating and landless households in a set of Indian villages where pre-existing census data on caste networks allows us to characterize the nature and extent of informal risk s...

Internet users such as individuals and organizations are subject to different types of epidemic risks such as worms, viruses, and botnets. To reduce the probability of risk, an Internet user generally invests in self-defense mechanisms like antivirus and antispam software. However, such software does not completely eliminate risk. Recent works have considered the problem of residual risk elimin...

Fair pricing of embedded options in life insurance contracts is usually conducted by using risk-neutral valuation. This pricing framework assumes a perfect hedging strategy, which insurance companies can hardly pursue in practice. In this paper, we extend the risk-neutral valuation concept with a risk measurement approach. We accomplish this by first calibrating contract parameters that lead to...

We study the effect of the life settlement market on the structure of long term contracts offered by the primary market for life insurance, as well as the effect on consumer welfare, using a dynamic model of life insurance with one sided commitment and bequest-driven lapsation. We show that the presence of life settlement affects the extent as well as the form of dynamic reclassification risk i...

We study how the presence of non-exclusive contracts limits the amount of insurance provided in a decentralized economy. We consider a dynamic Mirrleesian economy in which agents are privately informed about idiosyncratic labor productivity shocks. Agents sign insurance contracts with multiple firms (i.e., they are non-exclusive), which include both labor supply and savings aspects. These contr...
