As the share of supplementary health insurance (SI) in health care finance is likely to grow, SI may become an increasingly attractive tool for risk-selection in basic health insurance (BI). In this paper, we develop a conceptual framework to assess the probability that insurers will use SI for favourable risk-selection in BI. We apply our framework to five countries in which risk-...

Teamwork and cooperation between workers can be of substantial value to a firm, yet the level of worker cooperation often varies between individual firms. We show that these differences can be the result of labor market competition if workers have heterogeneous preferences and preferences are private information. In our model there are two types of workers: selfish workers who only...

A large experimental and empirical literature on asymmetric dominance and attraction effects shows that the probability that an alternative is chosen can increase if additional alternatives become available. Hence context matters and choices and, therefore, market shares can not be accurately described by standard choice models where individuals choose the alternative that yields the...

A new decision theory is proposed to explain the violations of expected utility theory through the role of random errors. The main premise of the new theory is that individuals make random errors when they compute the expected utility of a risky lottery. When being distorted by error, the expected utility of a lottery should neither exceed the utility of the highest possible outcome...

Concerns for relative performance are integrated into a model of contractual renegotiation in bilateral trade. It is shown that concernsnfor relative performance do never impede efficient trade. Moreover, conditional on renegotiation to occur, concerns for relative performance tend to mitigate material rent expropriation. However, concerns for relative performance make the occurrence...

This paper examines the role of geography and culture in explaining bankruptcy. We adopt survival analyses to model the bankruptcy risk of a firm, allowing for time-varying covariates. Based on a large sample from all major sectors of the Swiss economy, we find the following results: (i) The geographic location of a firm, which is characterized using a core-periphery approach, has a...

This paper argues that politicians are overprotected. The costs of politicalnassassination differ systematically depending on whether a private or a public point of view is taken. A politician attributes a very high (if not infinite) cost to his or her survival. The social cost of political assassination is much smaller as politicians are replaceable. Conversely, the private cost of...

Obesity is increasing worldwide for both adults and children. Genetic disposition is responsible for some variation in body weight but cannot explain the dramatic increase in the last two decades. The increase must be due to structural and behavioral changes. One such behavioral change is the increase in working females in the last decades. The absence from the mother reduces...

We discuss the ongoing liberalization process in the market for addressed letter mail in Switzerland. The core of the paper is an assessment of the liberalization's impact on the financial viability of various universal service obligations with and without access to the incumbent's downstream delivery network for customers and competitors. We propose a simple calibrated...
