Gender differences in the use of high-variance strategies in tournament competition

We report on a series of experiments in which participants first completed a simple game of chance and then competed in a tournament based on a multiple cue probability learning task. The results show that men made riskier choices in the simple game of chance, but women adopted the high-variance strategy more frequently in the tournament. However, after controlling for differences in forecasting skill, we find no significant differences in the rates at which men and women adopted a high-variance strategy. Although altering the difficulty of the forecasting task produces differences in the rate at which participants selected the high-variance strategy, it did not produce a significant difference in the rate at which men and women selected the strategy. Thus, this paper suggests that although women are more risk-averse than men, women are no less likely to adopt a high-variance strategy in a tournament competition.     

Gender differences in tournament and flat-wage schemes: An experimental study

We present a new experiment that explores gender differences in both performance and compensation choices. While most of the previous studies have focused on tournament vs. piece-rate schemes, the originality of our study consists in examining the gender gap in the context of a flat wage scheme. Our data indicate that females exert a significantly higher effort than men in fixed payment schemes. We find however no gender difference in performance under the tournament scheme, due to a combination of two effects. On the one hand, men more significantly increase their effort when switching from a flat wage to a tournament scheme. On the other hand, when switching from the flat wage to a tournament scheme, women have less margin to increase performance since their effort was already relatively high with a flat wage. We also find that females are more likely than males to choose a flat-wage scheme than a tournament. This gap however narrows dramatically when feedback on previous experience is provided.     

Gender differences in team work and team competition

We study whether the gender performance gap is affected by the gender composition of teams. A real-effort experiment is employed with wages based either on the team’s performance, or on the outcome of a competition between teams. We find that, relative to a single-sex environment, gender diversity increases the gender performance gap with team pay whereas it decreases the gap with team competition. The results show that there can be a tension between the objective to maximize overall performance and to minimize gender inequality.     

The willingness to pay–willingness to accept gap revisited: The role of emotions and moral satisfaction

While many earlier studies have found that people’s maximum willingness to pay for having a good is often substantially lower than their minimum willingness to accept not having it, more recent experimental evidence suggests that this discrepancy vanishes for standard consumption goods when an incentive-compatible design without misconceptions is used. This paper hypothesises that there is nevertheless a discrepancy for goods with a perceived moral character, such as contributions to a good cause, and moreover that the reason for this discrepancy can largely be explained by differences in emotions and moral perceptions. The results from a real-money dichotomous-choice experiment, combined with measurements of emotions and morality, are consistent with these hypotheses.     

Gender bias in performance evaluations: The impact of gender quotas

The intention behind imposing quotas for women on corporate boards is to close the gender gap in economic participation and help women to be promoted within organizations. However, the broader social psychological literature lends support to ideas that affirmative action policies, such as quotas, may do more harm than good for the beneficiaries. We extend this idea beyond the affected beneficiaries and ask whether this unintended negative effect spills over to women who are not immediate targets of the quota, by signaling incompetence. We develop an experimental design to investigate whether the announcement (study 1) and the implementation (study 2) of a quota for women have a direct negative effect on performance evaluations and hence reinforce the existing gender bias in evaluation. We observed that the performance of women was evaluated significantly lower than that of men. However, this gender bias was limited to sequential (rating) evaluations and was not evident in joint (ranking) evaluations. The quota did not significantly influence the amount of this bias. In addition, we observed more pronounced sexism in males compared to females. Results of study 2 gave a hint to an association between higher sexism and lower evaluations of women’s performance. We also found some evidence for a stronger evaluation bias in females when controlling for sexist attitudes. Hence, our results imply that the bias, which is overall quite robust and strongly pronounced, is still affected by individual gender-related characteristics.     

Gender differences in perceptions of aftercare supports and services

Youth depart residential care with many continued risk factors, unique needs, and challenges as they reintegrate into the home, school, and community settings. Currently, there is limited research on needs and best practices in aftercare services and supports for youth departing from residential settings and even less is known about how these differ by gender. While preliminary studies have explored perceptions of need during reintegration and aftercare by youth and caregivers, little is known about how these may differ by gender or if perceptions change over time after experiencing the initial transition period. One way to address this knowledge gap is to identify how prepared males and females feel for reintegration in critical life domains, their beliefs about aftercare, and preferences regarding potential services or supports to aide in the reintegration at discharge. Therefore, the purpose of this study was to explore if males and females differ on preparedness for reintegration across critical life domains, beliefs about aftercare, and preferences regarding potential services or supports to aide in the reintegration at departure from a residential treatment facility (N = 132). Overall, very few differences were found between males and females at departure. Implications, limitations, and future research are discussed.     

On the behavioural relevance of optional and mandatory impure public goods

Impure public goods combine a private good with a public good. Often, impure public goods have a charitable or ethical dimension, giving ethically motivated consumers a convenient option to contribute to public goods through the marketplace (in addition to direct donations). Impure public goods could potentially promote ethical giving or alternatively hinder charitable behaviour. We implement an economics experiment with a between-subject design to test the behavioural relevance of impure public goods with only a token (i.e. small) contribution to a public good. Contributions to the public good are negatively affected by the presence of impure public goods with token contributions. We explore one mechanism to offset this negative impact by making the token impure public good mandatory. We observe higher average contributions and several positive impacts on charitable behaviour, which supports the claim that this mechanism can potentially offset the negative impact of impure public goods.     

Placing Gender in Social Work: The Local and National Dimensions of Gender Relations

This paper argues that as well as being sensitive to wider discourses of gender relations, social workers need to consider the ways in which gender is localised. It is argued that to some extent gender practices vary according to local culture, that gendered identities are often localised and that social workers tend to construct their clients according to images of local men and women. These images tend to be stereotypical but some do also reflect dominant local gendered practices. The paper draws on data from qualitative interviews with social workers and probation officers, as well as the experience of teaching social work students, to illustrate these arguments. Whilst it is argued that the localising of gender is of general relevance, the data come from Wales alone. The author's conclusion is that (amongst other things) anti‐oppressive practice involves recognising the important influence of local stereotypes and challenging them, whilst also acknowledging that gendered practices do vary from place to place.     

When social accounts promote acceptance of unfair ultimatum offers: The role of the victim’s stress responses to uncertainty and power position

We examined which type of social account (denying responsibility versus apologizing) following an unfair offer makes recipients more likely to accept the offer in ultimatum bargaining. We identified stress responses to uncertainty as an individual difference factor that should moderate the relative effectiveness of these social accounts. A denial should make acceptance of an unfair offer more likely among recipients who respond to uncertainty with low stress. An apology should make such acceptance more likely among recipients who respond with high stress. Further, we argued that this cross-over interaction should be observed particularly among recipients interacting with a high power allocator. Two ultimatum bargaining experiments supported these ideas. Employing the perspective of victims of unfairness, the present research identifies a relevant individual difference moderator of the effectiveness of social accounts in bargaining situations and identifies power as a situational variable that promotes the expression of this factor.     

It does (not) get better: Reference income violation and altruism

We experimentally test whether the gap between reference and actual income impacts subsequent altruism. Participants first perform a real-effort task for a fixed wage and then play a dictator game. Between conditions, we vary the level and the timing of the revelation of the wage. In some conditions, participants know the wage before the real effort task and are not informed of the other potential levels. In some other conditions, they are informed of the distribution of wages before the real effort task, but the actual wage is only revealed afterward. Participants in the latter conditions can form references that may be higher or lower than their actual wage. Our hypothesis is that the gap between the reference and the actual wage impacts transfers in the subsequent dictator game, either because participants want to compensate their recent losses, or because of the emotional reaction to gains and losses. The results support this hypothesis: participants who get the low wage transfer less and are less likely to transfer when they are informed of the other potential levels than when they are not. Conversely, participants who get the high wage are more likely to transfer positive amounts when they are informed of the other potential levels. We use physiological (skin conductance response) and declarative data to discuss the role of emotions in our treatment effects.     

The efficacy of tables versus graphs in disrupting dark networks: An experimental study

An agent tasked with disrupting a dark (covert and illegal) network must first be presented with information about the organization's structure. This paper uses a behavioral experiment to test in a stylized dark network disruption setting whether an agent makes a better disruption choice when the information is displayed in a table or a graph format. We find that subjects make decisions more quickly when presented with graphs, but that subjects perform weakly better with tables. An important lesson is that the display should explicitly distinguish non-existent links from potential links of unknown status.     

Dictator game variants with probabilistic (and cost-saving) payoffs: A systematic test

Driven by methodological concerns, theoretical considerations, and previous evidence, I systematically test the validity of common dictator game variants with probabilistic payoffs. Using a unified experimental framework, I include four approaches and compare them to a standard dictator game: involving fewer receivers than dictators, paying only some players, paying only some decisions, and role uncertainty. I also relate transfers in the dictator game variants to established complementary individual difference measures of prosociality: social value orientation, personal values, a donation to charity, and the Big Five personality factor agreeableness. My data shows that the standard dictator game presents the expected correlations with the complementary measures of prosociality. Involving fewer receivers yields comparably valid results. By contrast, when only some players or decisions are paid or, particularly, when subjects face role uncertainty, the expected associations with complementary prosociality measures are distorted. Under role uncertainty, generosity is also significantly biased upward. I conclude that the validity of dictator game outcomes is highly sensitive to the applied methods. Not all dictator game variants can be recommended for the valid measurement of social preferences.     

The Proxy Effect: Gender and Gambling Problem Trajectories of Iowa Gambling Treatment Program Participants

Recent research has found that men and women who end up in gambling treatment tend to follow different trajectories to that endpoint: women generally begin gambling later in life, but progress to problems and seek treatment more quickly. With women’s prevalence rates of gambling and disordered gambling increasing, it has become important to identify the causes and consequences of these trajectory differences. The current study used a sample of 2,256 gamblers enrolled in the Iowa Gambling Treatment Program to examine the relationship of gender and other demographic, economic and health-related (i.e., psychosocial) factors to empirically-identified gambling problem trajectories. The results indicated that gender made a statistically significant contribution to the prediction of trajectory, but increased predictive accuracy by only 1–2% beyond a model with psychosocial predictors. Gender’s contribution was limited to its relationship to age of initiation; men and women’s problem progression did not differ meaningfully once age of gambling initiation was taken into account. Gender is a unique contributor to the development of gambling problems among treatment seekers, but it is only one small part of the myriad psychosocial characteristics that influence gambling problem development.

Replication: Framing effects in intertemporal choice with children

This paper investigates the effects of framing in intertemporal choice by elementary school children. Sutter, Yilmaz, and Oberauer (2015) recently demonstrated that intertemporal choice in children is malleable with respect to simple defaults. Using a similar approach, we replicated their study. We also found that children are more willing to select the immediate option in (standard) control frames than in alternative ones that appear to promote delay of gratification. This finding is consistent with previous experiments on children as well as adults and may have implications for cultivating the ability to delay gratification in individuals.     

The role of beliefs,trust, and risk in contributions to a public good

This paper experimentally investigates if and how beliefs, trust, and risk attitudes are associated with cooperative behavior. By applying incentivized elicitation methods to measure these concepts, we find that beliefs about others’ cooperation and trust are positively correlated with cooperation in a public goods game. However, even though contributing to a public good resembles a situation of making decisions under strategic uncertainty, elicited risk preferences do not seem to explain cooperation in a systematic way.     

The arithmetic of outcome editing in financial and social domains

Outcome editing refers to a set of mental rules that people apply when deciding whether to evaluate multiple outcomes jointly or separately, which subsequently affects choice. In a large-scale online survey (n = 2062) we investigate whether individuals use the same outcome editing rules for financial outcomes (e.g., a lottery win) and social outcomes (e.g., a party with friends). We also test the role of numeric ability in explaining outcome editing. Our results show that people’s preferences for combining or separating events depend on whether those events are in the financial or the social domain. Specifically, individuals were more likely to segregate social outcomes than monetary outcomes, except for when all outcomes were negative. Moreover, numeric ability was associated with preferences for outcome editing in the financial domain but not in the social domain. Our findings extend the understanding of the arithmetic operations underlying outcome editing and suggest that people rely more on calculations when making choices involving multiple financial outcomes and more on feelings when making choices involving social outcomes.     

Spillovers from targeting of incentives: Exploring responses to being excluded

A growing set of policies involve transfers conditioned upon socially desired actions, such as attending school or conserving forest. However, given a desire to maximize the impact of limited funds by avoiding transfers that do not change behavior, typically some potential recipients are excluded on the basis of their characteristics, their actions or at random. This paper uses a laboratory experiment to study the behavior of individuals excluded on different bases from a new incentive that encourages real monetary donations to a public environmental conservation program. We show that the donations from the individuals who were excluded based on prior high contributions fell significantly. Yet the rationale used for exclusion mattered, in that none of the other selection criteria used as the basis for exclusion resulted in negative effects on contributions.     

No mood effects in the field: The case of car inspections

We study mood effect in the field to measure its economic impact and address shortcomings in the existing literature, which typically uses one single mood proxy and ignores selection effects. Using over 50 million car inspections in Sweden and England and multiple mood proxies, we study whether car inspectors are more lenient on good mood days and if car owners self-select into those days. We find evidence of a “Friday effect” in England and a small selection bias, but no support for consistent mood effect. Our findings highlight the importance of considering the expectations of rational actors who may exploit mood effect and the need to study mood in the field using different settings and multiple proxies to avoid hasty conclusions.
