Overconfidence: the roles of gender, public observability and incentives 过度自信:性别、公众观察和激励的作用

Abstract In this project, we manipulate the public observability of forecasts and outcomes of a physical task. We explore how these manipulations affect overconfidence (OC). Participants in the experiment are asked to hold a weight after predicting how long they think they could do it for. Comparing the prediction and outcome times (in seconds) yields a measure of OC. We independently vary two dimensions of public observability (of the outcome and of the prediction). Additionally, we manipulate incentives to come up with an accurate prediction. This design allows us to shed light on the mechanism behind male and female OC. Following the existing literature, we formulate several hypotheses regarding the differences in predictions and outcomes for males and females in the presence of the public observability of predictions and outcomes. Our experimental data do not provide support to most of the hypotheses: in particular, there is no evidence of a gender gap in overconfidence. The most robust finding that emerges from our results is that incentives on making correct predictions increase participants’ forecasts on their own performance (by about 24%) and their actual performance as well, but to a lower extent (by about 8%); in addition, incentives to predict correctly in fact increase error for females (by about 33%).
在这个项目中,我们操纵一个物理任务的预测和结果的公众可观察性。我们探讨这些操作如何影响过度自信(OC)。实验参与者被要求在预测他们认为自己能坚持多久后,握住一个重物。比较预测时间和结果时间(以秒为单位)可以得到OC的度量。我们独立地改变了公众可观察性(结果和预测)的两个维度。此外,我们还会操纵动机来做出准确的预测。这种设计使我们能够阐明男性和女性OC背后的机制。在现有文献的基础上,我们提出了几个关于在预测和结果的公共可观察性存在下,男性和女性在预测和结果上的差异的假设。我们的实验数据并不能支持大多数假设:特别是,没有证据表明在过度自信方面存在性别差异。从我们的研究结果中得出的最有力的发现是,做出正确预测的激励会提高参与者对自己表现的预测(约24%)和他们的实际表现,但程度较低(约8%);此外,正确预测的激励实际上增加了女性的错误率(约33%)。

The Preference Survey Module: evidence on social preferences from Tehran 偏好调查模块:来自德黑兰的社会偏好证据
Pub Date : 2023-10-19 DOI: 10.1007/s40881-023-00151-5
Michael Kosfeld, Zahra Sharafi
Abstract We provide evidence on the extent to which survey items in the Preference Survey Module and the resulting Global Preference Survey measuring social preferences—trust, altruism, positive and negative reciprocity—predict behavior in corresponding experimental games outside the original participant sample of Falk et al. (Manag Sci, 2022. https://doi.org/10.1287/mnsc.2022.4455 ). Our results, which are based on a replication study with university students in Tehran, Iran, are mixed. While quantitative items considering hypothetical versions of the experimental games correlate significantly and economically meaningfully with individual behavior, none of the qualitative items show significant correlations. The only exception is altruism where results correspond more closely to the original findings.
我们提供了证据,证明偏好调查模块中的调查项目和由此产生的测量社会偏好的全球偏好调查(信任、利他主义、积极和消极互惠)在多大程度上预测了Falk等人原始参与者样本之外的相应实验游戏中的行为(管理科学,2022)。https://doi.org/10.1287/mnsc.2022.4455)。我们的研究结果是基于对伊朗德黑兰大学生的重复研究,结果好坏参半。考虑到实验游戏的假设版本的定量项目与个人行为具有显著的经济意义相关,但没有一个定性项目显示出显著的相关性。唯一的例外是利他主义,其结果更接近于最初的发现。

Adding household surveys to the behavioral economics toolbox: insights from the SOEP innovation sample 将家庭调查加入行为经济学工具箱:来自SOEP创新样本的见解

Abstract While laboratory and field experiments are the major items in the toolbox of behavioral economists, household panel studies can complement them and expand their research potential. We introduce the German Socio-Economic Panel’s Innovation Sample (SOEP-IS), which offers researchers detailed panel data and the possibility to collect personalized experimental and survey data for free. We discuss what SOEP-IS can offer to behavioral economists and illustrate a set of design ideas with examples. Although we build our discussion on SOEP-IS, our purpose is to provide a guide that can be generalized to other household panel studies as well.
虽然实验室和现场实验是行为经济学家工具箱中的主要项目,但家庭面板研究可以对其进行补充,扩大其研究潜力。我们介绍了德国社会经济小组的创新样本(SOEP-IS),它为研究人员提供了详细的小组数据,并可以免费收集个性化的实验和调查数据。我们讨论了soap - is可以为行为经济学家提供什么,并举例说明了一系列设计思想。虽然我们的讨论建立在soap - is上,但我们的目的是提供一个可以推广到其他家庭面板研究的指南。

stratEst: a software package for strategy frequency estimation 策略频率估计软件包
Pub Date : 2023-10-08 DOI: 10.1007/s40881-023-00141-7
Fabian Dvorak
Abstract stratEst is a software package for strategy frequency estimation in the freely available statistical computing environment R (R Development Core Team in R Foundation for Statistical Computing, Vienna, 2022). The package aims at minimizing the start-up costs of running the modern strategy frequency estimation techniques used in experimental economics. Strategy frequency estimation (Stahl and Wilson in J Econ Behav Organ 25: 309–327, 1994; Stahl and Wilson in Games Econ Behav, 10: 218–254, 1995) models the choices of participants in an economic experiment as a finite-mixture of individual decision strategies. The parameters of the model describe the associated behavior of each strategy and its frequency in the data. stratEst provides a convenient and flexible framework for strategy frequency estimation, allowing the user to customize, store and reuse sets of candidate strategies. The package includes useful functions for data processing and simulation, strategy programming, model estimation, parameter testing, model checking, and model selection.
stratEst是一个在免费提供的统计计算环境R (R Foundation for statistical computing, Vienna, 2022)中进行策略频率估计的软件包。该包旨在最小化运行实验经济学中使用的现代策略频率估计技术的启动成本。策略频率估计(Stahl and Wilson, journal of economic behavior, 25: 309-327, 1994);Stahl和Wilson在《游戏经济行为》(Games economics behavior, 10: 218-254, 1995)中将参与者在经济实验中的选择建模为个体决策策略的有限混合。模型的参数描述了每个策略的相关行为及其在数据中的频率。stratEst为策略频率估计提供了一个方便灵活的框架,允许用户自定义、存储和重用候选策略集。该软件包包括数据处理和仿真、策略规划、模型估计、参数测试、模型检查和模型选择的有用功能。

Abstract I find necessary and sufficient conditions for first-order stochastic dominance (FOSD) violations for choices from a budget line of Arrow securities. Applying this characterization to existing data, I compare FOSD violation rates across a broad set of risk preference elicitation tasks.
摘要本文从Arrow证券的预算线出发,找到了一阶随机优势(FOSD)违背的充分必要条件。将这一特征应用于现有数据,我比较了FOSD在广泛的风险偏好激发任务中的违反率。
