We study a matching model in which firms face budget constraints. If the pro-duction function only depends on a firm’s technology, a weak stable matching always exists; furthermore, when a strong stable matching does not exist, there is a nearby budget vector for firms such that a strong stable...

Worry over polarization has grown alongside the digital information consump-tion revolution. Where most scientific work considered user-generated and user-disseminated (i.e., Web 2.0) content as the culprit, the potential of purely increased access to informa-tion (or Web 1.0) has been largely...

People are not very good at detecting lies, which may explain why they refrain from accusing others of lying, given the social costs attached to false accusations — both for the accuser and the accused. Here we consider how this social balance might be disrupted by the availability of lie-detection...

The expectile is a prime candidate for being a standard risk measure in actuarial and financial contexts, for its ability to recover information about probabilities and typical behavior of extreme values, as well as its excellent axiomatic properties. A series of recent papers has focused on...

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

Models of sexual conflict over mating, including conflict over indirect benefits of mate choice, have generally presumed that female resistance to male coercion must involve direct confrontation, which can lead to sexually antagonistic coevolutionary arms-races. We built a quantitative model...

Drip pricing arises when a firm initially advertises a low price, then reveals additional fees as the consumer advances through the purchase process. We give examples of firms that have been pursued for engaging in drip pricing. We summarize theoretical papers on the topic, emphasizing the...

In this paper we use the enhanced consumption data in the Panel Survey of Income Dynamics (PSID) from 2005-2017 to explore the transmission of income shocks to consumption. We build on the nonlinear quantile framework introduced in Arellano, Blundell and Bonhomme (2017). Our focus is on the...

Because of population aging, dependency represents a major societal challenge. While some of the issues including insurance design and the provision of Long-Term-Care have recently been studied and debated, the potential role of prevention has been mostly neglected. To fill this gap the World...
