We analyze a dynamic and stochastic ecological-economic model of grazingmanagement in semi-arid rangelands. The non-equilibrium ecosystem is driven bystochastic precipitation. A risk averse farmer chooses a grazing management strategyunder uncertainty such as to maximize expected utility from...

Der Beitrag enthält eine anreiztheoretische Analyse der Versicherungssysteme, die zur Entschädigung von Kosten und Verlusten aus Tierseuchenausbrüchen in den EU-Mitgliedsländern eingerichtet sind. Es wird gezeigt, dass Kompensationszahlungen zur Erzielung effizienter...

In an information cascade experiment participants are confronted with artificial predecessors predicting in line with the BHW model (Bikchandani et al.,1992). Using the BDM (Becker et al., 1964) mechanism we study participants'probability perceptions based on maximum prices for participating in...

Experimental and field evidence show that people perceive and evaluate new risks differently from risks that are common. In particular, people get used to the presence of certain risks and become less eager to avoid them. We explain this observation by including risks in the reference states of...

We extend the definition of a convex risk measure to a conditionalframework where additional information is available. We characterize these riskmeasures through the associated acceptance sets and prove a representationresult in terms of conditional expectations. As an example we consider the...

The influence of risk aversion on the decision to become self-employed is a much discussedtopic in the entrepreneurial literature. Conventional wisdom asserts that the role model of anentrepreneur requires to make risky decisions in uncertain environments and hence thatmore risk-averse...

This paper delevops a tools to analyse the ordering of concordance of random vectors.

This papfer deals with distributional free inference to test for positive quadrant dependence, i.e. for the probability that two variables are simultaneously small (or large) being at least as great as it would be were they dependent.

Natural catastrophes attract regularly the attention of media and have become a source of public concern. From a financial viewpoint, natural catastrophes represent idiosyncratic risks,diversifiable at the world level. But for reasons analyzed in this pap er reinsurance markets are unable to...

This paper argues that observations of non-stationary choice behavior need notnecessarily imply specific properties of the individual’s discount function. As weshow, the observed “anomalies” in intertemporal choice can alternatively be explained by an individual’s perception of the risk...
