Decisions involving risk are usually taken in the presence of other insurable or non-insurable risks, the latter type called background risk. We examine how changing background risk influences risk-taking based on panel data with monthly observations from Senegalese fishermen. Fishing income is...

We analyze the effect of environmental uncertainties on optimal fishery management in a bio-economic fishery model. Unlike most of the literature on resource economics, but in line with ecological models, we allow the different biological processes of survival and recruitment to be affected...

Using the new macro data on risk aversion and patience by Falk et al. (2018), I show that risk aversion and patience are related to intelligence: high-IQ populations are more patient and more risk averse than low-IQ populations. The correlation between patience and intelligence corroborates...

Wie viel Umverteilung Bürgerinnen und Bürger in der Gesellschaft möchten, hängt von sozioökonomischen Faktoren und ihren Ansichten über Gerechtigkeit ab. Diese Studie, basierend auf einer in Schweden durchgeführten, repräsentativen Umfrage, bestätigt frühere Ergebnisse: Demnach nimmt...

One fundamental assumption often made in the literature on unawareness is that risk preferences are invariant to changes of awareness. We study how exposure to unawareness affects choices under risk. Participants in our experiment choose repeatedly between varying sure outcomes and a lottery in...

This paper studies soil depletion incentives in a dynamic economic model under two different sources of revenue uncertainty (production- and output price risk). The focus is on the long-term effects of risk averse preferences. The land manager is assumed to posses three classes of instruments to...

This paper solves the irreversible investment decision problem under uncertainty by a new real options method. It yields a Shadow Net Present Value rule such that the investment is triggered only when the shadow revenue of the investment reaches the investment cost. This paper hence corrects and...

While humans often care about sunk investment, animals are not subject to this sort of sunk cost behavior or "Concorde fallacy". This paper investigates a simple two stage decision problem under uncertainty. At the second stage, subjects can commit the Concorde fallacy by sticking to the first...

We analyse risk preferences using an experiment with real incentives in a representative sample of 1,422 Dutch respondents. Our econometric model incorporates four structural parameters that vary with observed and unobserved characteristics: Utility curvature, loss aversion, preferences towards...

In this paper we provide a generalization of the standard models of the diffusion of a new product. Consumers are heterogeneous and risk averse, and the firm is uncertain about the demand curve: both learn from past observations. The attitude towards risk has important effects with regard to the...
