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...

Travelers often are incompletely informed about travel alternatives, which has important implications for various domains of travel behavior such as whether or not to make a trip, modal choice, the timing of a trip or route choice. During the last decade large efforts have been made to increase...

In thispaper we compare various modelling approaches to address uncertainty and demonstrate … thatignoring uncertainty issues may easily lead to distorted estimates of values of travel time. Thisis of special relevance in …

In this paper we perform a meta-analysis on empirical estimates of the impact between investment and uncertainty. Since … can explain to a large extent why empirical estimates of the investment-uncertainty relationship differ. …

There has been a revival of interest in the effect of risk on economic growth. We quantify both ex ante and ex post … effects of risk using a stochastic version of the Ramsey model.

Most measures of vulnerability are a-theoretic and essentially static. In this paper we use a stochastic Ramsey model to find a household's optimal welfare and we measure vulnerability as the shortfall from the welfare attained if the household consumed permanently at the poverty line. The...
