Ambiguity on audits and cooperation in a public goods game

We investigate the impact of various audit schemes on the provision of public goods, when contributing less than the average of the other group members is centrally sanctioned and the probability of an audit is unknown. We study how individuals update their beliefs about the probability of being audited, both before and after audits are permanently withdrawn. We find that when individuals have initially experienced systematic audits, they decrease both their beliefs and their contributions almost immediately after audits are withdrawn. In contrast, when audits were initially less frequent and more irregular, they maintain high beliefs and continue cooperating long after audits have been withdrawn. This identifies the compliance effect of irregularity and uncertainty due to learning difficulties. By increasing both the frequency of audits and the severity of sanctions, we also identify an educative effect of frequent and high sanctions on further cooperation.     

The effects of task outcome feedback and broad domain evaluation experience on the use of unique scorecard measures

Prior research has found that division evaluators using balanced scorecards in a performance evaluation process relied almost solely on common measures and virtually ignored unique measures. Other studies have found certain situations in which measures that are unique to a particular division are not completely ignored. However, no study has addressed whether outcome feedback over a period of time can motivate evaluators to rely more on unique measures that are predictive of future financial results. Our study involving executives with varying levels of prior evaluation experience examines two factors that may lead to increased use of unique measures: task outcome feedback and broad domain evaluation experience. Results provide evidence of increased reliance on unique measures after multiple periods as evaluators receive outcome feedback showing the predictive value of these unique measures. Further, results indicate that unique measures are used more over time when the prior evaluation experience of the participants is relatively high.     

Individual or team decision-making—Causes and consequences of self-selection

Even though decision-making in small teams is pervasive in business and private life, little is known about subjects' preferences with respect to individual and team decision-making and about the consequences of respecting these preferences. We report the results from an experimental beauty-contest game where subjects could endogenously choose their preferred way of decision-making. About 60% of them preferred to decide in a team, and teams won the game significantly more often than individuals did. Nevertheless, both individuals and teams were highly satisfied with their chosen role, though for different reasons.     

Blowing the Whistle

Leniency clauses, offering cartelists legal immunity if they blow the whistle on each other, is a recent anti-trust innovation. The authorities wish to thwart cartels and promote competition. This effect is not evident, however; whistle-blowing may enforce trust and collusion by providing a tool for cartelists to punish each other. We examine the impact of leniency law, and other rules, experimentally.     

Trust and trustworthiness across different age groups

We examine the degree of trust and trustworthiness in an experimental trust game with 662 participants from six different age groups, ranging from 8-year-olds to retired persons. Although both trust and trustworthiness have been identified as fundamental pillars for efficient economic interactions, economic research has devoted little attention to measuring their strength in different age groups. In our experiment subjects interact with members of the same age group. We find that trust increases almost linearly from early childhood to early adulthood, but stays rather constant within different adult age groups. Trustworthiness prevails in all age groups.     

A behavioral study of supply manager decision-making: Factors influencing make versus buy evaluation

This paper investigates behavioral factors influencing a supply manager's decision to insource or outsource the manufacture of a product component. To do so we posit a theoretical framework that integrates the heretofore distinct operational make–buy literature and the behavioral decision-making literature. Within the framework three factors influencing the make–buy decision are brought into account: the decision-maker's perception of supply risk or “strategic vulnerability”, the degree of core competency represented by the product component under consideration and the formality of the information about supply alternatives. The results of a controlled experimental survey show that: strategic vulnerability and core competency do influence the make–buy decision, strategic vulnerability has greater influence than core competency and information formality moderates the make–buy decision when the strategic vulnerability and core competency conditions are mixed. The practical implications of these results include the notion that management can ensure a more rational make–buy decision if they understand the biases that influence the decision and point these biases out to the decision maker.     

Congestion allocation for distributed networks: an experimental study

This paper reports an experimental study of two prominent congestion and cost allocation mechanisms for distributed networks. We study the fair queuing (or serial) and the FIFO (or average cost pricing) mechanisms under two different treatments: a complete information treatment and a limited information treatment designed to simulate distributed networks. Experimental results show that the fair queuing mechanism performs significantly better than FIFO in all treatments in terms of efficiency, predictability measured as frequency of equilibrium play, and the speed of convergence to equilibrium.

茶农生物农药属性偏好及支付意愿研究——基于选择实验的实证分析

利用选择实验方法实证分析了茶农生物农药属性偏好和支付意愿。结果表明:(1)茶农偏好"缩短安全间隔期""不提前使用"和"不产生抗药性"的农药属性,但在"缩短安全间隔期"和"针对防治"上存在偏好异质性;(2)茶农愿为优化3类属性多支付16.974、22.250和11.272元/亩/年;(3)种植面积小、受教育年限长、化学农药危害认知程度高的茶农倾向于选择生物农药;(4)生物农药实际支付高于各属性加总的意愿支付,应关注生物农药外部性。
