With the progress of artificial intelligence and the emergence of global online communities, humans and machines are increasingly participating in mixed collectives in which they can help or hinder each other. Human societies have had thousands of years to consolidate the social norms that promote...

Musculoskeletal pain is the most debilitating human health condition. Neurophysiological pain mechanisms are highly conserved and promote somatic maintenance and learning to avoid future harm. However, some chronic pain might be more common owing to mismatches between modern lifestyles and traits...

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...

We study partial identification of the preference parameters in the one-to-one matching model with perfectly transferable utilities. We do so without imposing parametric distributional as-sumptions on the unobserved heterogeneity and with data on one large market. We provide a tractable...

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...
