- We perform a meta analysis of gender differences in the standard windfall gains dictator game (DG) by collecting raw data from 53 studies with 117 conditions, giving us 15,016 unique individual observations. We find that women on average give 4 percentage points more than men (Cohen's d = 0.16), and that this difference decreases to 3.1% points (Cohen's d = 0.13) if we exclude studies where dictators can only give all or nothing. The gender difference is larger if the recipient in the DG is a charity, compared to the standard DG with an anonymous individual as the recipient (a 10.9 versus a 2.3% points gender difference). These effect sizes imply that many individual studies on gender differences are underpowered; the median power in our sample of standard DG studies is only 9% to detect the meta-analytic gender difference at the 5% significance level. Moving forward on this topic, sample sizes should thus be substantially larger than what has been the norm in the past.

- We study gender differences in altruism in a large random sample of the Swedish population using a standard dictator game. Beside a baseline treatment we implement a priming treatment where participants are reminded of their gender, and two treatments with known male and female counterpart respectively. We find suggestive evidence that women are more altruistic than men only in the priming treatment. A post-hoc analysis using data on interviewer gender to explore gender context effects indicates that priming affects behavior only in mixedgender contexts.

Tidskriftsartikel (refereegranskat)abstract
- Experimental results from student and other non-representative convenience samples often suggest that men, on average, are more risk taking and competitive than women. We explore whether these gender preference gaps also exist in incentivized tasks in a simple random sample of the Swedish adult population. Our design comprises four different conditions to systematically explore how the experimental context may impact gender gaps; a baseline condition, a condition where participants are primed with their own gender, and two conditions where the participants know the gender of their counterpart (man or woman). We further look at competitiveness in two domains: a math task and a verbal task. We find no gender gap in risk taking or competitiveness in the verbal task in this random sample. There is some support for men being more competitive than women in the math task in the pooled sample, but the effect size is small. We further find no consistent impact of the respective conditions on (the absence of) the gender gap in preferences.

The subgroup problem : When can binding voting on extractions from a common pool resource overcome the tragedy of the commons?

- Using a common pool resource game protocol with voting we examine experimentally how cooperation varies with the level at which (binding) votes are aggregated. Our results are broadly in line with theoretical predictions. When players can vote on the behavior of the whole group or when leaders from each group can vote for the group as a whole, extraction levels from the common resource pool are close to the social optimum. When players extract resources individually, there is substantial overextraction. When players vote in subgroups, there is initially less overextraction but it increases over time. This suggests that in order for binding voting to overcome the tragedy of the commons in social dilemmas, it should ideally affect the group as a whole.

- The replicability of some scientific findings has recently been called into question. To contribute data about replicability in economics, we replicated 18 studies published in the American Economic Review and the Quarterly Journal of Economics between 2011 and 2014. All of these replications followed predefined analysis plans that weremade publicly available beforehand, and they all have a statistical power of at least 90% to detect the original effect size at the 5% significance level. We found a significant effect in the same direction as in the original study for 11 replications (61%); on average, the replicated effect size is 66% of the original. The replicability rate varies between 67% and 78% for four additional replicability indicators, including a prediction market measure of peer beliefs.

- We look at gender differences among adolescents in Sweden in preferences for competition, altruism and risk. For competitiveness, we explore two different tasks that differ in associated stereotypes. We find no gender difference in competitiveness when comparing performance under competition to that without competition. We further find that boys and girls are equally likely to self-select into competition in a verbal task, but that boys are significantly more likely to choose to compete in a mathematical task. This gender gap diminishes and becomes non-significant when we control for actual performance, beliefs about relative performance, and risk preferences, or for beliefs only. Girls are also more altruistic and less risk taking than boys.

Why do women ask for less?

Tidskriftsartikel (refereegranskat)abstract
- Women are often less likely to negotiate or ask for less when they do negotiate compared to men. In this study, we send out a survey to a large sample of recent college graduates in Sweden. We ask respondents whether they made an explicit salary request and what the outcome was. We include several questions on beliefs and attitudes towards negotiations. While women are more likely to state a salary request, we find that they on average ask for less than men. This gender gap is reduced when we control for beliefs and attitudes. However, neither perceived social costs nor confidence appear to matter for the gender gap. Instead, while men and women consider themselves relatively similar to an ideal candidate applying for the same job, they differ on average in their beliefs about what constitutes a reasonable request amount for the ideal candidate. This variable is the only statistically significant mediating variable of the gender gap in salary requests, and suggests that information interventions affecting beliefs could potentially reduce the gender gap in negotiations. As our results are correlational they should however be interpreted with caution. © 2022 The Authors

Outrunning the Gender Gap - Boys and Girls Compete Equally

Tidskriftsartikel (refereegranskat)abstract
- Recent studies find that women are less competitive than men. This gender difference in competitiveness has been suggested as one possible explanation for why men occupy the majority of top positions in many sectors. In this study we explore competitiveness in children, with the premise that both context and gendered stereotypes regarding the task at hand may influence competitive behavior. A related field experiment on Israeli children shows that only boys react to competition by running faster when competing in a race. We here test if there is a gender gap in running among 7-10 year old Swedish children. We also introduce two female sports, skipping rope and dancing, to see if competitiveness is task dependent. We find no gender difference in reaction to competition in any task; boys and girls compete equally. Studies in different environments with different types of tasks are thus important in order to make generalizable claims about gender differences in competitiveness.

- Being able to replicate scientific findings is crucial for scientific progress1-15. We replicate 21 systematically selected experimental studies in the social sciences published in Nature and Science between 2010 and 201516-36. The replications follow analysis plans reviewed by the original authors and pre-registered prior to the replications. The replications are high powered, with sample sizes on average about five times higher than in the original studies. We find a significant effect in the same direction as the original study for 13 (62%) studies, and the effect size of the replications is on average about 50% of the original effect size. Replicability varies between 12 (57%) and 14 (67%) studies for complementary replicability indicators. Consistent with these results, the estimated truepositive rate is 67% in a Bayesian analysis. The relative effect size of true positives is estimated to be 71%, suggesting that both false positives and inflated effect sizes of true positives contribute to imperfect reproducibility. Furthermore, we find that peer beliefs of replicability are strongly related to replicability, suggesting that the research community could predict which results would replicate and that failures to replicate were not the result of chance alone.

A creative destruction approach to replication : Implicit work and sex morality across cultures

Tidskriftsartikel (refereegranskat)abstract
- How can we maximize what is learned from a replication study? In the creative destruction approach to replication, the original hypothesis is compared not only to the null hypothesis, but also to predictions derived from multiple alternative theoretical accounts of the phenomenon. To this end, new populations and measures are included in the design in addition to the original ones, to help determine which theory best accounts for the results across multiple key outcomes and contexts. The present pre-registered empirical project compared the Implicit Puritanism account of intuitive work and sex morality to theories positing regional, religious, and social class differences; explicit rather than implicit cultural differences in values; self-expression vs. survival values as a key cultural fault line; the general moralization of work; and false positive effects. Contradicting Implicit Puritanism's core theoretical claim of a distinct American work morality, a number of targeted findings replicated across multiple comparison cultures, whereas several failed to replicate in all samples and were identified as likely false positives. No support emerged for theories predicting regional variability and specific individual-differences moderators (religious affiliation, religiosity, and education level). Overall, the results provide evidence that work is intuitively moralized across cultures.
