This paper was aimed to investigate the mixed empirical results on the effect of health insurance in reducing the risk of catastrophic health expenditure (CHE). We investigated a wide range of factors affecting the risk of CHE among patients admitted to hospitals in Tehran. We categorized hospitals into five groups from private hospitals to charity ones. The data used herein was extracted from ...

A typical shortcoming of most current credit portfolio models is the lack of a stochastic modeling of risk factors, such as interest rates or credit spreads, during the revaluation process at the risk horizon. Within the simple credit risk model underlying the Internal Ratings-based approach of Basel II with incorporated correlated interest rate risk the effect which results from neglecting the...

Since insuring agricultural products is one of the effective instruments for risk management in agricultural sector, it can reduce risk avoidance among farmers and increase their competence in using production factors and, consequently, increases their inclination towards investment in agricultural sectors. The purpose of the current study was to investigate the factors influencing policyholder...

Risk-sharing in insurance is analyzed, with a view towards explaining the prevalence of deductibles. First we introduce, in a modern setting, the main concepts of the theory of risk-sharing in a group of agents. This theory we apply to the risk-sharing problem between an insurer and an insurance customer. We motivate the development through simple examples, illustrating some of the subtle point...

Can public income insurance through progressive income taxation improve the allocation of risk in an economy where private risk sharing is incomplete? The answer depends crucially on the fundamental friction that limits private risk sharing in the first place. If risk sharing is limited because insurance markets are missing for model-exogenous reasons (as in Bewley, 1986) publicly provided risk...

Comparing and ordering of risks is a basic problem of actuarial theory and practice. Risks are generally modeled by random variables or distribution functions. There is a great variety of stochastic models in use which reflect the diversity of insurances like theft insurance, car insurance, liability insurance, etc. The diversity of insured populations is reproduced in the stochastic models by ...

Moral hazard in natural disaster insurance markets has the effect that policyholders prepare less for disasters, which increases the risk they face. However, moral hazard may not arise due to high risk aversion of insured individuals and/or the inherent insurance market context. We offer a comprehensive empirical study of the relation between disaster risk reduction and insurance coverage to as...
