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...

We set up a formal framework to characterize encompassing of nonparametric mod-els through the L2 distance. We contrast it to previous literature on the comparison of nonparametric regression models. We then develop testing procedures for the encom-passing hypothesis that are fully nonparametric....

We study personalized pricing in a general oligopoly model. The impact of personalized pricing relative to uniform pricing hinges on the degree of market coverage. If market conditions are such that coverage is high (e.g., the production cost is low, or the number of firms is high), personalized...

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 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...
