The Purpose and Limits of Social Health Insurance

This contribution seeks to answer two related questions. First, what is the purpose of social health insurance? Or put in slightly different terms, what are the reasons for social (or public) health insurance to exist, even to dominate private health insurance in most developed countries? And second, what are the limits of social health insurance? Can one say that there is "too much" social health insurance in the following two senses: Should the balance be shifted towards the private alternative? And is the degree of coverage excessive?social health insurance, private health insurance, insurance coverage

Flight experience with windshear detection

Windshear alerts resulting from the Honeywell Windshear Detection and Guidance System are presented based on data from approximately 248,000 revenue flights at Piedmont Airlines. The data indicate that the detection system provides a significant benefit to the flight crew of the aircraft. In addition, nuisance and false alerts were found to occur at an acceptably low rate to maintain flight crew confidence in the system. Data from a digital flight recorder is also presented which shows the maximum and minimum windshear magnitudes recorded for a representative number of flights in February, 1987. The effect of the boundary layer of a steady state wind is also discussed

Income redistribution: how to divide the pie?

In this paper, we elicit preferences of Swiss citizens for the allocation of income redistribution to different uses through a Discrete Choice Experiment performed in 2008. Neustadt and Zweifel (2009} provide an estimate of the total desired amount of income redistribution as a share of disposable income. Here, we estimate marginal willingness-to-pay values for types of recipients (old-age pensioners, people with ill health, the unemployed, working poor, and families with children) and their nationality (Swiss, citizens of western European countries, others). Hypotheses derived from the insurance motive for redistribution receive some empirical support.Income redistribution, preferences, willingness to pay, discrete choice experiments, conjoint analysis, social status

Is the Welfare State Sustainable? Experimental Evidence on Citizens' Preferences for Redistribution

The sustainability of the welfare state ultimately depends on citizens' preferences for income redistribution. They are elicited through a Discrete Choice Experiment performed in 2008 in Switzerland. Attributes are redistribution as GDP share, its uses (the unemployed, old-age pensioners, people with ill health etc.), and nationality of beneficiary. Estimated marginal willingness to pay (WTP) is positive among those who deem benefits too low, and negative otherwise. However, even those who state that government should reduce income inequality exhibit a negative WTP on average. The major finding is that estimated average WTP is maximum at 21% of GDP, clearly below the current value of 25%. Thus, the present Swiss welfare state does not appear sustainable.Income redistribution; welfare state; sustainability; preferences; willingness to pay; discrete choice experiments

Economic Well-Being, Social Mobility, and Preferences for Income Redistribution: Evidence from a Discrete Choice Experiment

In this paper, preferences for income redistribution in Switzerland are elicited through a Discrete Choice Experiment (DCE) performed in 2008. In addition to the amount of redistribution as a share of GDP, attributes also included its uses (working poor, the unemployed, old-age pensioners, families with children, people in ill health) and nationality of beneficiary (Swiss, Western European, others). Willingness to pay for redistribution increases with income and education, contradicting the conventional Meltzer-Richard (1981) model. The Prospect of Upward Mobility hypothesis [Hirschman and Rothschild (1973); Benabou and Ok (2001)] receives partial empirical support.Income redistribution, preferences, willingness to pay, discrete choice experiments, stated choice, economic well-being, social mobility

Flat-of-the-Curve Medicine – A New Perspective on the Production of Health

Health economists have studied the determinants of the expected value of health status as a function of medical and nonmedical inputs, often finding small marginal effects of the former. This paper argues that both types of input have an additional benefit, viz. a reduced variability of health status. Using OECD health data for 24 countries between 1960 and 2004, medical and nonmedical inputs are found to reduce the variability of life expectancy. While the evidence supports the "flat-of-the-curve medicine" hypothesis with respect to the expected value of life expectancy and its variability, healthcare expenditure is comparatively effective in reducing variability.production of health, control over health status, Gini coefficient

How Much Internalization of Nuclear Risk Through Liability Insurance?

An important source of conflict surrounding nuclear energy is that with a very small probability, a large-scale nuclear accident may occur. One way to internalize the financial risks associated with such an accident is through mandatory liability insurance. This paper presents estimates of the willingness to pay for increased financial security provided by an extension of coverage, based on the `stated choice' approach. A Swiss citizen with median characteristics may be willing to pay 0.08 cents per kwh to increase coverage beyond the current CHF 0.7 bn. (US$0.47 bn.). Marginal willingness to pay declines with higher coverage but exceeds marginal cost at least up to a coverage of CHF 4 bn. (US$ 2.7 bn.). An extension of nuclear liability insurance coverage therefore may be effciency-enhancing.risk, nuclear energy, liability insurance, internalization

Is regulating the solvency of banks counter-productive?

This paper contains a critique of solvency regulation such as imposed on banks by Basel I and II. It argues that banks seeking to maximize rate of return on risk-adjusted capital (RORAC) aim at an optimal level of solvency because on the one hand, solvency S lowers the cost of refinancing; on the other, it ties costly capital. In period 1, exogenous changes in mean returns dµ and in volatility occur, causing optimal adjustments dS * / dµ and dS * / ds in period 2. Since banks reallocate their assets with certain µ and s values in response to the changed solvency level, an endogenous trade-off with slope dµ / ds results in period 3. Both Basel I and II are shown to modify this slope, inducing at least some banks to opt for a higher value of s in certain situations. Therefore, this type of solvency regulation can prove counter-productive
