Advantageous selection occurs when the agents most eager to buy insurance are also the cheapest ones to insure. Hemenway (1990) links it to differences in risk-aversion among agents, implying different prevention efforts, and finally different riskinesses. We argue that it may also appear when...

The 50-year old concept of an evolutionarily stable strategy provided a key toolfor theorists to model ultimate drivers of behaviour in social interactions. Fordecades, economists ignored ultimate drivers and used models in which individ-uals choose strategies based on their preferences—a proximate...

Individuals’ monetary values of decreases in mortality risk depend on the magnitude and timing of the risk reduction. We elicited stated preferences among three time paths of risk reduction yielding the same increase in life expectancy (decreasing risk for the next decade, subtracting a constant...

Evolutionary game theory and the adaptive dynamics approach have made invaluable contributions to understanding how gradual evolution leads to adaptation when individuals interact. Here, we review some of the basic tools that have come out of these contributions to model the evolution of...

Identification of peer effects is complicated by the fact that the individuals under study may self-select their peers. Random assignment to peer groups has proven useful to sidestep such a concern. In the absence of a formal randomization mechanism it needs to be argued that assignment is `as good...

This paper examines the impact of most favored nation (MFN) clauses on retail prices, taking advantage of two natural experiments that changed vertical contracting between hotels and major digital platforms. The broad E.U. intervention narrowed the breadth of “price parity” obligations between...

This study presents evidence from a lab-in-the-field experiment, conducted in eight small, rural villages in Mexico, in which subjects choose to exert real effort to fund real health centers in their own and other localities. The results show that women are more willing than men to exert effort to...

Consider a three-tier industry with a monopolist supplying a manufacturer which sells its product to final consumers through two retailers. Contracts are linear and secret. Hence, upon receiving an out-of-equilibrium offer, each retailer must form a belief about the identity of the deviating...
