Biodiversity prospecting refers to the exploration of the commercial value of genetic and biochemical resources. In this chapter, we study a drug producing pharmaceutical firm (PF) that searches for potentially useful chemicals made by wild organisms in a conservation area. This PF is able to...

We analyze the relation between an individual's risk attitude and his willingness to engage in unprotected sexual behavior, when faced with an asymptomatic infectious disease. In such a situation, the individual must not only assess the likely health status of his partner, but must also form...

This paper empirically assesses how financial risk aversion reacts to a change in individuals' wealth and health and to the presence of both financial and health risks using the Survey of Health, Ageing, and Retirement in Europe (SHARE). Individuals in our sample exhibit financial risk aversion...

We describe a risk protocol that combines the rigor of economic studies of risk with the ecological validity of tasks from psychology. Despite a wealth of experimental contributions on risk preferences, stemming from a variety of elicitation tasks, the external validity of standard measures of...

This paper investigates the effect of ambiguity on personal vaccination decision. We first characterize the vaccination decision in the absence of ambiguity. We then show that uncertainty about the probability of side effects and the efficacy of the vaccine always reduce take-up under ambiguity...

We estimate the long-term effects of start-up subsidies (SUS) for the unemployed on subjective outcome indicators of well-being, as measured by the participants' satisfaction in different domains. This extends previous analyses of the current German SUS program ("Gründungszuschuss") that...

Combining a standard measure of concern about low relative wealth and a standard measure of relative risk aversion leads to a novel explanation of variation in risk-taking behavior identified and documented by social psychologists and economists. We obtain two results: (1) Holding individual i's...

A perception at the core of studies that consider the link between social rank and stress (typically measured by the so-called stress hormone cortisol) is that the link is direct. Examples of such studies are Bartolomucci (2007), Beery and Kaufer (2015), and Koolhaas et al. (2017). A recent and...
