Alexithymia, a difficulty identifying and communicating one’s own emotions, affects socio-emotional processes, such as emotion recognition and empathy. Co-occurring alexithymia is prevalent in Autism Spectrum Disorder (ASD) and underlies some socio-emotional difficulties usually attributed to...

The human evolutionary sciences place high value on quantitative data from traditional small‐scale societies that are rapidly modernizing. These data often stem from the sustained ethnographic work of anthropologists who are today nearing the end of their careers. Yet many quantitative ethnographic...

In the paper, we introduce and analyze a new methodology to estimate the volatility functions of jump diffusion models. Our methodology relies on the standard kernel estimation technique using truncated bipower increments. The relevant asymptotics are fully developed, which allow for the time span...

We consider quasi likelihood ratio (QLR) tests for restrictions on parameters under potential model misspecification. For convex M-estimation, including quantile regression, we propose a general and simple nonparametric bootstrap procedure that yields asymptotically valid critical values. The...

A major problem that resulted from the massive use of social media networks is the diffusion of incorrect information. However, very few studies have investigated the impact of incorrect information on individual and collective decisions. We performed experiments in which participants had to...

Policies to incentivize the adoption of renewable energy sources (RES) usually offer little flexibility to adapt to heterogeneous benefits across locations. We evaluate the geographical misallocation of RES associated with the uniform nature of subsidies. We estimate the dispersion of marginal...

Econometric land use models study determinants of land-use-shares of different classes: ``agriculture'', ``forest'', ``urban'' and ``other'' for example. Land-use-shares have a compositional nature as well as an important spatial dimension. We compare two compositional regression models with a...

Even if there exists an extensive literature on the modeling of farmers’ behavior under risk, actual measurements of the quantitative impact of risk aversion on input use are rare. In this article we use simulated data to quantify the impact of risk aversion on the optimal quantity of input and...

Dans les analyses relatives au choix du mode de réalisation des grands projets d’investissements publics, dont les grands projets d’infrastructure, entre le mode MOP (maîtrise d’ouvrage publique, ou CSP comparateur secteur public, ou mode conventionnel) et le mode PPP (partenariat public-privé),...

The paper investigates factors that undermine meritocracy and policies that may restore it. To this purpose, it analyzes the Markovian dynamics, the entrenchment and the welfare properties of an organization whose members’ cooptation decisions are driven by two motives: quality and homophily. It...
