Public Policy for Efficient Education
We study the role of public policy in promoting efficiency in human capital accumulation. Agents accumulate human capital by allocating time to home study and school attendance. The return to time spent in school is subject to congestion. The individual also faces an aggregate externality in skill accumulation. We find that a tuition fee combined with personal stipends can correct...

Relative Implied-Volatility Arbitrage with Index Options
This study investigates the efficiency of markets as to the relative pricing of similar risk by using implied volatilities of options on highly correlated indexes and a statistical arbitrage strategy to profit from potential mispricings. It first analyzes the interrelationships over time of the 3 most highly correlated and liquid pairs of US stock indexes. Based on this analysis, the...

The Impact of Economic Sanctions on South African Exports
In the mid-1980s many nations imposed sanctions on South African exports, most of which were subsequently removed during 1991-3. I estimate the effect of eight industrialized economies' sanctions on their imports from South Africa. Outliers are found to strongly influence the parameter estimates. Failure to take account of them leads to the conclusion that sanctions by the (then...

Psychiatric and psychological assessment after parasuicide is characterized by a number of difficulties. The interview is a strategically complex task for the patients trying to accommodate the wishes of the psychiatrist/psychologist and their own goals. The psychiatrist/ psychologist on the other hand needs to gain information about the event and the patient's mental state, has...

Introducing Procedural Utility: Not only What, but also How Matters
People not only care about outcomes, they also value the procedures which lead to the outcomes. Procedural utility is a potentially important source of human well-being. This paper aims at introducing the concept of procedural utility into economics, and argues that it should be incorporated more widely into economic theory and empirical research. Three building blocks of a concept...

Microeconometric Evaluation of the Active Labour Market Policy in Switzerland
In the second part of the 1990's Switzerland conducted an ambitious active labour market policy (ALMP) encompassing a wide variety of programmes. We evaluate the effects of these programmes on the individual employment probability of potential participants. Our econometric analysis uses unusually informative data origi-nating from administrative unemployment and social security...

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,...

Stochastic Strategy Adjustment in Coordination Games
The paper explores a model of equilibrium selection in coordination games, where agents from an infinite population stochastically adjust their strategies to changes in their local environment. Instead of playing perturbed best-response, it is assumed that agents follow a rule of `switching to better strategies with higher probability'. This behavioral rule is related to bounded...

Do Workers Enjoy Procedural Utility?
People are likely to obtain utility not only from actual outcomes, but also from the conditions which lead to these outcomes. This paper empirically tests the notion of procedural utility for the context of work relationships. Using a large survey among British workers, we find substantial procedural effects on the utility workers derive from their pay. Utility from pay is not only...

Health Care Reform and the Number of Doctor Visits An Econometric Analysis
The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure and data from the German Socio- Economic Panel for the years 1995-1999. A number of modified count data models allow to estimate the effect of the reform in different parts of the distribution. The overall effect of the reform was a 10 percent reduction in the...

Infrastructure Quality in Deregulated Industries: Is there an Underinvestment Problem?
We investigate how various institutional settings affect a network provider’s incentives to invest in infrastructure quality. Under reasonable assumptions on demand, investment incentives turn out to be smaller under vertical separation than under vertical integration, though we also provide counter-examples. The introduction of downstream competition for the market can sometimes...

A myopic adjustment process leading to best-reply matching
We analyze a myopic strategy adjustment process in strategic-form games. It is shown that the steady states of the continuous time limit, which is constructed assuming frequent play and slow adjustment of strategies, are exactly the best-reply matching equilibria, as discussed by Droste, Kosfeld, and Voorneveld (2000. Mimeo, Tilburg University). In a best-reply matching equilibrium...
