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...

Der Schweizer Mietimmobilienmarkt belohnt andere Nachhaltigkeitsmerkmale als Energieeffizienz

Analysiert wird der Einfluss von Nachhaltigkeitsmerkmalen auf die Bestandesmieten von 3120 Wohnungen. Im Ergebnis zeigen sich substanzielle Mietprämien für Tageslicht, geringe Strahlenbelastung und ökologische Baumaterialien sowie ÖV-Anschluss.
Ein schwach signifikanter Mietpreisabschlag wird für Flexibilität sowie Heizwärmebedarf ermittelt.

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...

The Sovereign Debt Crisis: Rebalancing or Freezes?

Using high-frequency data we document that episodes of market turmoil in the European sovereign bond market are on average associated with large decreases in trading volume. The response of trading volume to market stress is conditional on transaction costs. Low transaction cost turmoil episodes are associated with volume increases (investors rebalance), while high transaction cost...

"Einfach so drauflosexperimentieren geht nicht"

In der Neuroökonomie werden bisweilen auch Gedanken manipuliert. Das weckt Abwehrreflexe. Der Neuroökonom Christian Ruff sieht aber wenig Missbrauchspotenzial.

On the Continuity and Origin of Identity in Distributed Ledgers: Learning from Russell's Paradox

This article studies the origin and continuity of the identity of the entities inscribed in a distributed ledger. Specifically, it focuses on the differences between the identities of the entities that exist in a distributed ledger and those of the entities that exist outside the ledger but must be represented in the ledger in order to interact with it. It suggests that a distributed...

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...

Growing and slowing down like China

This article is based on the presidential address delivered at the EEA Annual Congress 2016. It discusses China’s institutional and economic transformation through the lens of the model of growth and convergence developed in Acemoglu, Aghion, and Zilibotti (JEEA 2006), which emphasizes the dichotomy between investment- and innovation-led growth. The economic reforms introduced in the...

Creating an efficient culture of cooperation

Throughout human history, informal sanctions by peers were ubiquitous and played a key role in the enforcement of social norms and the provision of public goods. However, a considerable body of evidence suggests that informal peer sanctions cause large collateral damage and efficiency costs. This raises the question whether peer sanctioning systems exist that avoid these costs and...
