Gender differences in willingness to compete: The role of public observability

A recent literature emphasizes that gender differences in the labor market may in part be driven by a gender gap in willingness to compete. However, whereas experiments in this literature typically investigate willingness to compete in private environments, real world competitions often have a more public nature, which introduces potential social image concerns. If such image concerns are important, and men and women differ in the degree to which they want to be seen as competitive, making tournament entry decisions publicly observable may further exacerbate the gender gap. We test this prediction using a laboratory experiment (N = 784) that varies the degree to which the decision to compete, and its outcome, is publicly observable. We find that public observability does not alter the magnitude of the gender gap in willingness to compete in an economically or statistically significant way.

平教会定县实验中的农村卫生工作之考察

中华平民教育促进会定县实验区在二十世纪三十年代创立了一套由村保健员、乡保健所、县保健院组成的三级卫生保健网,并在学校卫生、妇婴保健、传染病预防和疾病治疗等方面做出了显著的成绩,在当时产生了广泛的影响,对我们今天来说仍值得借鉴。     

Learning in experiments: Dynamic interaction of policy variables designed to deter tax evasion

While neoclassical economic theory sheds insight into the way that audit rates and penalty rates interact when individuals decide to declare income for taxation, it predicts far lower levels of compliance than observed levels of compliance. This paper analyses experimental responses to explore a dynamic interaction between audit and penalty rates as individuals learn how to comply with taxation. It compares the responses of subjects in experiments with responses that are predicted when individuals rely on an adaptive learning process (that offers information feedback about decision payoffs). This comparison suggests that learning is an important consideration when explaining differences between predicted and observed levels of tax compliance.

Measuring people's trust

Summary. We measure trust and trustworthiness in British society with a newly designed experiment using real monetary rewards and a sample of the British population. The study also asks the typical survey question that aims to measure trust, showing that it does not predict 'trust' as measured in the experiment. Overall, about 40% of people were willing to trust a stranger in our experiment, and their trust was rewarded half of the time. Analysis of variation in the trust behaviour in our survey suggests that trusting is more likely if people are older, their financial situation is either 'comfortable' or 'difficult' compared with 'doing alright' or 'just getting by', they are a homeowner or they are divorced, separated or never married compared with those who are married or cohabiting. Trustworthiness also is more likely among subjects who are divorced or separated relative to those who are married or cohabiting, and less likely among subjects who perceive their financial situation as 'just getting by' or 'difficult'. We also analyse the effect of attitudes towards risks on trust.     

1978年以来中国改革成功的原因探究——有限理性政府试错式改革与满意实现

实现改革过程中经济社会的平稳和发展即满意,需要政府的合理抉择;而政府的有限理性则决定了合理的政府抉择必须是一个基于解决问题,采取合适试错方式的改革过程。解决问题要求政府通过信息分析,准确诊断社会状况,提出事前能为社会接受的改革方案。合适试错式改革要求有限理性政府通过试错式改革平衡社会发展和稳定的动态要求,掌握改革主导权。就迄今为止的中国改革而言,由于政府在试错式改革过程中牢牢把握住了发展、改革和稳定三位一体的执政理念,时刻注意自己的抉择与经济社会的协调,从而能比较满意地实现改革目标。
