Fines, corporal punishments, and other procedures of punitive justice recur across small-scale societies. Although they are often assumed to enforce group norms, we here propose the relation-restoration hypothesis of punitive justice, according to which punitive procedures function to restore...

Nous présentons un modèle simple d’investissements en capital humain qui peut tenir compte d’une grande hétérogénéité entre agents, et nous étudions sa compatibilité avec certains modèles de recherche d’emploi et de salaire d’équilibre qui ont été proposés dans la littérature. Nous montrons que l’...

Low-income individuals are typically the most price sensitive segment of the mar-ket, but this is not true in the market for health care services. I show that low-income individuals have a smaller demand elasticity of medical spending with re-spect to coinsurance, relative to their higher income...

We adapt the methods from Abreu, Pearce and Stacchetti (1990) to finitely repeated games with imperfect public monitoring. Under a combination of (a slight strengthening of) the assumptions of Benoıˆt and Krishna (1985) and those of Fudenberg, Levine and Maskin (1994), a folk theorem follows. Three...

We empirically study whether carbon emissions affect firms’ cost of capital raised on conventional bond markets. We find that firms with higher carbon emissions face higher spreads in the secondary market but not in the primary market. We show that this gap is related to uncertainty about climate...

This document introduces a parsimonious novel method of processing textual data based on the NMF factorization and on supervised clustering withWasserstein barycenter’s to reduce the dimension of the model. This dual treatment of textual data allows for a representation of a text as a probability...

We study how temporary visa schemes can be designed to drive smugglers out of business while meeting labor market needs in host countries. After discussing their compatibility with a large range of policy objectives, we show how combining internal and external controls with a regulated market for...

The cost of germline maintenance gives rise to a trade-off between lowering the deleterious mutation rate and investing in life history functions. Therefore, life history and the mutation rate coevolve, but this coevolution is not well understood. We develop a mathematical model to analyse the...

We consider a procurement auction for the provision of a basic service to which an add-on must later be appended. Potential providers are symmetric, have private information on their cost for the basic service and the winning firm must also implement the add-on. To finance cost-reducing activities...

We develop a model of a device ecosystem to study how network structure affects demand, pricing, and output for the underlying products. Prices depend on each device's Katz-Bonacich centrality in a network defined by the demand-side externalities linking devices. We show how the relevant network...
