Competitive pricing reduces wasteful counterproductive behaviors
Counterproductive reactions to unfavorable trading prices can cause inefficiencies in economic exchange. This paper studies whether the use of a competitive pricing mechanism reduces such wasteful activities. We report data from a laboratory experiment where a powerful buyer can trade with one of two sellers—an environment that can lead to very low prices for the sellers. We find...

Numerical implementation of the QuEST function
Certain estimation problems involving the covariance matrix in large dimensions are considered. Due to the breakdown of finite-dimensional asymptotic theory when the dimension is not negligible with respect to the sample size, it is necessary to resort to an alternative framework known as large-dimensional asymptotics. Recently, an estimator of the eigenvalues of the population...

The welfare effects of vertical integration in multichannel television markets
We investigate the welfare effects of vertical integration of regional sports networks (RSNs) with programming distributors in U.S. multichannel television markets. Vertical integration can enhance efficiency by reducing double marginalization and increasing carriage of channels, but can also harm welfare due to foreclosure and incentives to raise rivals' costs. We estimate a...

Improving weighted least squares inference
These days, it is common practice to base inference about the coefficients in a hetoskedastic linear model on the ordinary least squares estimator in conjunction with using heteroskedasticity consistent standard errors. Even when the true form of heteroskedasticity is unknown, heteroskedasticity consistent standard errors can also used to base valid inference on a weighted least...

The regulation of public service broadcasters: should there be more advertising on television?
Increased competition for viewers’ time is threatening the viability of public-service broadcasters (PSBs) around the world. Changing regulations regarding advertising minutes might increase revenues, but little is known about the structure of advertising demand. To address this problem, we collect a unique dataset on monthly impacts (quantities) and prices of UK television channels...

Die Verteilung von Einkommen und Vermögen in der Schweiz
Das Interesse an der Verteilung von Einkommen und Vermögen ist in jüngster Zeit wieder neu entbrannt. Nicht zuletzt, weil nach vielen Jahren der Stabilität die Ungleichheit in vielen Ländern wieder zunimmt. Auch in der Schweiz geniesst die Frage nach der Einkommens- und Vermögensverteilung in der öffentlichen und politischen Diskussion grosse Aufmerksamkeit. Die Analyse über die...

The impact of peer personality on academic achievement
This paper provides evidence of a novel facet of peer effects by showing how peer personality affects educational achievement. We exploit random assignment of students to university sections and find that students perform better in the presence of more persistent peers and more risk-averse peers. In particular, low-persistence students benefit from highly-persistent peers without...

The effect of peer gender on major choice
This paper investigates how the peer gender composition in university affects students' major choices and labor market outcomes. Women who are randomly assigned to more female peers become less likely to choose male-dominated majors, they end up in jobs where they work fewer hours and their wage grows at a slower rate. Men become more likely to choose male-dominated majors after...

Do gender preference gaps impact policy outcomes?
Many studies document systematic gender differences in a variety of important economic preferences, such as risk-taking, competition and pro-sociality. One potential implication of this literature is that increased female representation in decision-making bodies may significantly alter organizational and policy outcomes. However, research has yet to establish a direct connection from...

On the scope of externalities in experimental markets
We study how the scope of negative externalities from market activity affects the willingness of market actors to exhibit social responsibility. Using the laboratory experimental paradigm introduced by Bartling et al. (Q J Econ 130(1):219–266, 2015), we compare the voluntary internalization of negative social impacts by market actors in cases where the negative externality is...

Food-predicting stimuli differentially influence eye movements and goal-directed behavior in normal-weight, overweight, and obese Individuals
Obese individuals have been shown to exhibit abnormal sensitivity to rewards and reward-predicting cues as for example food-associated cues frequently used in advertisements. It has also been shown that food-associated cues can increase goal-directed behavior but it is currently unknown, whether this effect differs between normal-weight, overweight, and obese individuals. Here, we...

Brain stimulation over the frontopolar cortex enhances motivation to exert effort for reward
Background: Loss of motivation is a characteristic feature of several psychiatric and neurological disorders. However, the neural mechanisms underlying human motivation are far from being understood. Here, we investigate the role that the frontopolar cortex (FPC) plays in motivating cognitive and physical effort exertion by computing subjective effort equivalents.
Methods: We...

The dopaminergic reward system underpins gender differences in social preferences
Women are known to have stronger prosocial preferences than men, but it remains an open question as to how these behavioural differences arise from differences in brain functioning. Here, we provide a neurobiological account for the hypothesized gender difference. In a pharmacological study and an independent neuroimaging study, we tested the hypothesis that the neural reward system...

Estimating fixed effects: perfect prediction and bias in binary response panel models, with an application to the hospital readmissions reduction program
The maximum likelihood estimator for the regression coefficients, β, in a panel binary response model with fixed effects can be severely biased if N is large and T is small, a consequence of the incidental parameters problem. This has led to the development of conditional maximum likelihood estimators and, more recently, to estimators that remove the O(T–1) bias in β^. We add to this...

Persistent bias in advice-giving
We show that a one-off incentive to bias advice has persistent effects. In an experiment, advisers were paid a bonus to recommend a lottery which only risk-seeking individuals should choose to a less informed client. Afterwards, they had to choose for themselves and make a second recommendation to another client, without any bonus. These advisers choose the risky lottery and...

Ordinal potentials in smooth games
While smooth exact potential games are easily characterized in terms of the cross-derivatives of players' payoff functions, an analogous differentiable characterization of ordinal or generalized ordinal potential games has been elusive for a long time. In this paper, it is shown that the existence of a generalized ordinal potential in a smooth game with multi-dimensional...
