While it is commonly assumed that farmers have higher, and foragers lower, fertility compared to populations practicing other forms of subsistence, robust supportive evidence is lacking. We tested whether subsistence activities—incorporating market integration—are associated with fertility in 10,...

Cooperation usually becomes harder to sustain as groups become larger because incentives to shirk increase with the number of potential contributors to collective action. But is this always the case? Here we study a binary-action cooperative dilemma where a public good is provided as long as not...

Direct reciprocity is a powerful mechanism for cooperation in social dilemmas. The very logic of reciprocity, however, seems to require that individuals are symmetric, and that everyone has the same means to influence each others’ payoffs. Yet in many applications, individuals are asymmetric....

Being overweight or obese is associated with lower employment and earnings, possibly arising from employer discrimination. A few studies have used field experiments to show that obese job applicants are, in fact, discriminated against in the hiring process. However, whether overweight job...

We study a simple model of consumption of animals in which consumers exhibit altruism towards animals. Consumers can choose both the quantity and the quality of animal lives. This model gives rise to a public good problem: at the market equilibrium, quality is too low, and quantity is too high when...

We study the profitability of bundling by an upstream firm that licenses technologies to downstream competitors, and that faces competition for one of its technologies. In an otherwise standard “Chicago-style” model, the existence of downstream competition can make inefficient bundling profitable....

While antitrust authorities strive to detect, prosecute, and thereby deter collusive conduct, entities harmed by that conduct are also advised to pursue their own strategies to deter collusion. The implications of such delegation of deterrence have largely been ignored, however. In a procurement...

To succeed, we posit that research cartography will require high-throughput natural description to identify unknown unknowns in a particular design space. High-throughput natural description, the systematic collection and annotation of representative corpora of real-world stimuli, faces logistical...

This paper studies continuing optimal lockdowns (can also be interpreted as quaran-tines or self-isolation) in the long run if a disease (Covid-19) is endemic and immunity can fail, that is, the disease has SIRS dynamics. We model how disease related mortality affects the optimal choices in a...

We consider a situation where the distribution of a random variable is being estimated by the empirical distribution of noisy measurements of that variable. This is common practice in, for example, teacher value-added models and other fixed-effect models for panel data. We use an asymptotic...
