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’...

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...

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...

The paper makes the case for a more systematic ex-ante assessment of the distribution of gains and losses from efficiency enhancing innovations that regulatory sandboxes are expected to test. It shows how a prior formal modelling of tests can inform the regulators on the possible need to control...

The strategy method (SM) is, in practice, subject to a possibly severe economic-theoretical bias. Although many studies utilize SM to examine responses to rare or off-equilibrium behaviors unattainable through direct elicitation (DE), they ignore the fact that the strategic equivalence between SM...

Research shows that opposition to policies that redistribute across racial divides has affected the development of the American welfare state. Are similar dynamics at play in Western Europe? For many scholars, the answer is yes. In contrast, we argue that researchers' understanding of the political...

Voters’ voting decisions crucially depend on their information. Thus, it is an important question how much / what kind of information they should know, as a normative guidance of the optimal extent of transparency. We consider a simple two-alternative majority voting environment, and study the...

Studying the content and impact of news articles has been a recurring interest in economics, finance, psychology, and political and media literature over the last 20 years. Most of these offerings focus on specific qualities or outcomes related to their textual data, which limits their...

We extend nonparametric regression smoothing splines to a context where there is endogeneity and instrumental variables are available. Unlike popular existing es-timators, the resulting estimator is one-step and relies on a unique regularization parameter. We derive uniform rates of the convergence...

We investigate the welfare effects of third-degree price discrimination by a two-sided platform that enables interaction between buyers and sellers. Sellers are heterogenous with respect to their per-interaction benefit, and, under price discrimination, the platform can condition its fee on sellers...
