Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, to compute the corresponding premiums, and thereby to reduce asymmetric information. Permitting risk classification may reduce informational asymmetry-induced...

Here, we argue that the commercial for-profit insurance companies act more like a memory-less system in a way that the premiums paid by the policy holders during one accounting period will be of no avail to them during subsequent periods although the excess premiums earned in the previous...

Background: We propose using neighborhood characteristics as demand-related morbidity adjusters to improve prediction models such as the risk equalization model. Results: Since the neighborhood has no explicit ‘place’ in healthcare demand models, we have developed the “Neighborhood and...

In-kind transfers can provide insurance benefits when prices of consumption goods vary, as is common in developing countries. We develop a model demonstrating that in-kind transfers are welfare improving to beneficiaries relative to cash if the covariance between the marginal utility of income...

Job-related welfare entitlements are common in China. Migrants who do not hold urban registration are, in principle, not entitled to job-related welfare even if they are employees in the State sector. The official explanation is that rural-urban migrants are allocated access to farm land in...

The paper derives the optimal carbon tax in closed-form from an integrated assessment of climate change. The formula shows how carbon, temperature, and economic dynamics quantify the optimal mitigation effort. The model's descriptive power is comparable to numeric models used in policy advising....

Background: In Switzerland, age is the predominant driver of solidarity transfers in risk adjustment (RA). Concerns have been voiced regarding growing imbalances in cost sharing between young and old insured due to demographic changes (larger fraction of elderly 65 years and rise in average...

This paper analyzes the interaction of direct and indirect risk selection in health insurance markets. It is shown that direct risk selection - using measures unrelated to the benefit package like selective advertising or 'losing' applications of high risk individuals - nevertheless has an...

I analyze a critical illness insurance in a consumption-investment model over the life cycle. I solve a model with stochastic mortality risk and health shock risk numerically. These shocks are interpreted as critical illness and can negatively affect the expected remaining lifetime, the health...

Climate has relevant impacts on human health. According to the World Health Organization (WHO), climate-sensitive health problems kill millions of people every year and undermine the physical and psychological health of millions (WHO, 2012). In the particular case of vector-borne diseases,...
