Quasilinear preferences on a public good and a numeraire good are limits of preferences where both goods are normal. The set of equilibria of the voluntary contribution (or private provision) game is easily characterized under quasilinearity by: top valuators aggregately contribute their common...

Human-generated greenhouse gas emissions imperil a global resource: a biosphere capable of supporting life as we know it. What is the fair way to share this scarce resource across present and future generations and across regions of the world? This study offers a new perspective based on the...

Various experimental procedures aimed at measuring individual risk aversion involve a list of pairs of alternative prospects. We first study the widely used method by Holt and Laury (Am Econ Rev 92(5):1644–1655, <CitationRef CitationID="CR21">2002</CitationRef>), for which we find that the removal of some items from the lists yields a...</citationref>

What determines risk attraction or aversion? We experimentally examine three factors: the gain-loss dichotomy, the probabilities (0.2 vs. 0.8), and the money at risk (7 amounts). We find that the majority display risk attraction for small amounts of money, and risk aversion for larger amounts....

Prospect Theory asserts that people display risk attraction in high-probability losses. But our subjects tend to avoid fair risks for large ([euro]30 to [euro]90), high-probability (80%) real losses, vindicating Bernoulli's view that risk aversion is the dominant attitude.
