Large dynamic covariance matrices
Second moments of asset returns are important for risk management and portfolio selection. The problem of estimating second moments can be approached from two angles: time series and the cross-section. In time series, the key is to account for conditional heteroskedasticity; a favored model is Dynamic Conditional Correlation (DCC), derived from the ARCH/GARCH family started by Engle...

On the convergence of logit-response to (strict) Nash equilibria
We show that the logit-response dynamics converges to a subset of (strict) Nash equilibria for any weakly acyclic, N-player normal form game. The result holds independently of whether revision opportunities arise as in asynchronous learning or in other ways, as long as the dynamics is regular. Our analysis generalizes and organizes recent convergence results in the literature....

Government distortion in independently owned media: evidence from U.S. Cold War news coverage of human rights
This study provides evidence of government distortion of news coverage among independently owned media outlets in a democratic regime. It uses data from 1946 to 2010 and documents that U.S. news coverage of human rights abuses committed by foreign governments was associated with membership on the United Nations Security Council and the degree of political alliance with the United...

Altered reward anticipation: Potential explanation for weight gain in schizophrenia?
Obesity and weight gain are severe complications of mental illness, especially schizophrenia. They result from changes in lifestyle and nutrition, side effects of medication and other, less well-understood factors. Recent studies suggest that obesity and weight gain are linked to psychopathology. Specifically, severe psychopathology is associated with greater weight dysregulation,...

"Mafia Inc.": when godfathers become entrepreneurs
We study the investment of criminal organizations in the legal economy. We focus on Italy, a country historically plagued by a conspicuous presence of mafia-type organizations. By using the exogenous credit contraction imposed by the 2007 financial crisis we highlight how the consequences for newly established enterprises have been less severe in areas with organized crime. Although...

The neural circuitry of emotion-induced distortions of trust
Aversive emotions are likely to be a key source of irrational human decision-making but still little is known about the underlying neural circuitry. Here, we show that aversive emotions distort trust decisions and cause significant changes in the associated neural circuitry. They reduce trust and suppress trust-specific activity in left temporoparietal junction (TPJ). In addition,...

Understanding peer effects: on the nature, estimation, and channels of peer effects
This paper estimates peer effects in a university context where students are randomly assigned to sections. While students benefit from better peers on average, low-achieving students are harmed by high-achieving peers. Analyzing students’ course evaluations suggests that peer effects are driven by improved group interaction rather than adjustments in teachers’ behavior or students’...

Adaptive value normalization in the prefrontal cortex is reduced by memory load
Adaptation facilitates neural representation of a wide range of diverse inputs, including reward values. Adaptive value coding typically relies on contextual information either obtained from the environment or retrieved from and maintained in memory. However, it is unknown whether having to retrieve and maintain context information modulates the brain’s capacity for value adaptation...

Sind Workaholics unzufriedener?
Einkommensungleichheiten führen zu einer ungleichen Verteilung der meisten auf dem Markt käuflichen Güter. Es ist allerdings unklar, wie sich das Einkommen auf den Konsum von sozialen Gütern wie Freundetreffen oder Vereinsaktivitäten auswirkt. Marktgüter und Sozialgüter unterscheiden sich konzeptuell, indem der Konsum Ersterer vor allem Geld, der Konsum Letzterer hingegen vor allem...

Competition in agricultural markets: an experimental approach
This paper develops an experimental approach to measure competition among intermediaries in agricultural markets, based on the random allocation of subsidies to traders. We show that, in individual-level randomizations with competitive spillovers, treatment-control differences in prices can inform an intuitive test of the degree of differentiation among firms. In the context of the...

La visite d'entreprise rend-elle l'entreprise hospitalière: : expérience d'accueil et dimension culturelle au-travers de visites d'entreprises suisses et françaises
L'objectif de cet article est de caractériser la visite d'entreprise comme une situation d'hospitalité et de comprendre en quoi elle peut représenter un facteur de différenciation et ainsi répondre à des préoccupations managériales de transmission de savoir-faire et de relation avec les visiteurs. Ce travail, de nature exploratoire, répond à deux buts : il est tout d...

Perception des risques ; déterminants de la perception des risques, effet sur le comportement pro-social et la satisfaction au travail: : une analyse empirique au sein d’un corps de police de suisse romande
Le métier de policier est reconnu pour être un métier difficile, ou le collaborateur qui l’exerce peut être exposé à toute une série de risques divers dans l’exercice de sa profession (Monjardet 1996). L’exposition à ces risques peut générer un stress qui aura un impact sur la satisfaction au travail, la motivation, le comportement des collaborateurs, et, in fine, la performance de...
