How did humans evolve from individualistic foraging to collective foraging with sex differences in food production and widespread sharing of plant and animal foods? While current models of food sharing focus on meat or cooking, considerations of the economics of foraging for extracted plant foods (e...

We study second-degree price discrimination by a two-sided monopoly platform. The incentive constraints of the agents on the value creation side may be in conflict with internalizing externalities on the value capture side, which may render pooling optimal. Even without such conflict between the...

We introduce a new second order stochastic algorithm to estimate the entropically regularized optimal transport cost between two probability measures. The source measure can be arbitrary chosen, either absolutely continuous or discrete, while the target measure is assumed to be discrete. To solve...

A key issue distinguishing prominent evolutionary models of human life history is whether prolonged childhood evolved to facilitate learning in a skill- and strength-intensive foraging niche requiring high levels of cooperation. Considering the diversity of environments humans inhabit, children’s...

Organizations may suffer from unforeseen negative shocks, potentially leading to severe bottlenecks. This paper studies an optimal incentive scheme robust to those shocks in the effort induction problem in team production. The optimal scheme under the no-shock assumption is typically vulnerable in...

The social value of decreasing health risks can be evaluated using benefit-cost analysis (BCA), cost-effectiveness analysis (CEA), or a social-welfare function (SWF). These frameworks can produce different social preference rankings of interventions depending on how their health effects and costs...
