Promises and Partnership

We examine experimentally the impact of communication on trust and cooperation. Our design admits observation of promises, lies, and beliefs. The evidence is consistent with people striving to live up to others' expectations so as to avoid guilt, as can be modeled using psychological game theory. When players exhibit such guilt aversion, communication may influence motivation and behavior by influencing beliefs about beliefs. Promises may enhance trustworthy behavior, which is what we observe. We argue that guilt aversion may be relevant for understanding strategic interaction in a variety of settings, and that it may shed light on the role of language, discussions, agreements, and social norms in these contexts.     

公平偏好、强互惠倾向和农民合作社生产 规范的演化分析

面对农民合作社的现实发展困境,在充分考量我国农户社会心理的基础上,将公平偏好和强互惠倾向纳入合作社农户的效用函数中;构建了合作社农户的生产行为演化博弈模型,分析了不同情形下合作社生产规范的演化逻辑;然后通过数值实验演示了公平偏好、强互惠倾向、守规农户初始比例等参数的变化对合作社生产规范演化趋势的影响。研究发现,守规农户越强的不公平厌恶程度以及搭便车农户越低的内疚程度,越容易导致合作社陷入全体农户生产低质量产品的困境;守规农户的强互惠倾向有利于维持合作社的稳定性;初始阶段较大的守规农户比例、生产高质量产品较低的额外成本以及较高的质量价格加成系数都有助于合作社向良性的生产规范演化。     

More than self-interest: Why different classes have different attitudes to income inequality

The connection between social class and political preferences is among the most well established in the social sciences. This association is typically taken as prima facie evidence of economic self-interest: Classes hold different attitudes, values, and party preferences because they have different economic interests. However, this assumption has rarely been tested empirically. In this article, we use survey data from 18 West European countries to examine why classes differ on a central aspect of political preferences, namely their views on the desirability of income inequality. We find that only a moderate proportion of differences between employee classes in support for redistribution can be accounted for by contemporary differences in resources and risks; differences in economic interests to some degree account for the anti-redistributive preferences of the professional middle classes compared with the working class. However, the preferences of the self-employed have a different explanation; autonomy is a better explanation of the right-wing preferences of the self-employed compared with the working class.     

Elicitation of Decision-Makers'Preferences for Management of Major Hazards

A survey has been conducted among decision-makers from the urban area of Lyon (France). It aimed at elicitating attitudes toward industrial risk, with an emphasis on major hazards. The sample was quite small (23 individuals), but most of the actual decision-makers of the area belonged to it. A questionnaire allowed to look at the weights that are given to "catastrophic accidents," when compared to more usual ones. It showed that decision-makers are strongly "adverse to catastrophes." The findings support many risk management approaches that are based on assigning an "extra weight" to potential accidents that may cause a high number of casualties.     

Assigning volunteer tasks: The relation between task preferences and functional motives of youth volunteers

In this paper we aim to explore the relationship between volunteer motives and task preferences in order to provide volunteer managers with better insight in how tasks can be assigned to keep youth volunteers satisfied. Earlier seminal contributions have either taken a pure functional approach – where various types of motives are supposed to be at the base of any type of volunteer work – or a differentiated approach, where particular motives relate to specific task preferences. However, empirical results reported in the literature do not justify the preference of one approach above the other. To investigate whether one of the approaches is superior, or whether a combination of both is more appropriate, we perform a canonical correlation analysis for a set of functional motives and a set of task preferences (N = 2158). Five distinct relationships (canonical variate pairs) of motives and preferences are found. Results show that a ‘functional basis’ exists where all motives relate to a basic set of tasks. Additionally, a more differentiated approach towards volunteer motives and task preferences has to be taken, as we find four other relationships where specific motives are satisfied by assigning particular sets of tasks.     

The Political Consequences of Outsider Labour Market Status in the United States: A Micro‐level Study

This article contributes to recent research that seeks to understand the political consequences of ‘outsider’ labour market status. There is an emerging consensus that labour market outsiders have systematically different policy preferences and display systematically different political behaviour to securely employed ‘insiders’ in Europe. Yet the political consequences of outsider status in the USA are less clear. They may be expected to differ from those that have been documented in the European context, because: (1) the USA is characterized by low employment protection of insiders; and (2) there is evidence that Americans are more reluctant than Europeans to hold governments responsible for personal economic hardship. We therefore use the General Social Survey to examine how outsider labour market status is related to voting behaviour and to social policy preferences in the USA. We find that the concept of ‘labour market outsider’ – as conventionally operationalized – holds little explanatory power in the American context. Disaggregating the outsider category, our results suggest that the political consequences of outsider labour market status may be contingent on individual beliefs about government responsibility.     

Preferences in teams and hierarchies

This paper describes the methodology developed for a laboratory for project selection and the results of use of the computerized ranking procedure for other complex managerial decisions. In addition to project selection, the system is feasible and instructive in personnel selection, comparison of management strategies, purchasing decisions and merit-based distribution of awards. The massive input required by many existing systems is not necessary for this absolute deviation ranking system. Up to 20 attributes and 200 projects can be compared. Measures of consistency and reliability arc proposed for estimating the validity of the final weights. Preliminary experiments and actual use of the system provide empirical validation. The system offers an organized, structured way of making decisions which enhances the identification and subsequent refinement of criteria considered, and provides a concise, highly credible format for presentation and justification of decisions.     

Choice under complete uncertainty when outcome spaces are state dependent

One central objection to the maximin payoff criterion is that it focuses on the state that yields the lowest payoffs regardless of how low these are. We allow different states to have different sets of possible outcomes and show that the original axioms of Milnor (1954) continue to characterize the maximin payoff criterion, provided that the sets of payoffs achievable across states overlap. If instead payoffs in some states are always lower than in all others then ignoring the “bad” states is no longer inconsistent with these axioms. Similar dependence on overlap of outcome spaces across states holds for the minimax regret and maximin joy criteria.      

Intergenerational transfer of time and risk preferences

There is a growing interest in individual time and risk preferences. Little is known about how these preferences are formed. It is hypothesised that parents may transmit their preferences to their offspring. This paper examines the correlation in offspring and parental time and risk preferences using data from an annual household survey in Australia (the HILDA survey). Both time and risk preferences are examined and we explored whether the correlation in time and risk preferences varies across the distribution of preferences and across the across the four parent–child dyads (mother/daughter, mother/son, father/daughter, father/son). The results show that there is a significant relationship between parents and their young adult offspring risk and time preference measures. The correlation varies across the distribution of time preferences. The correlation was largest for longer planning horizons. Risk averse parents are more likely to have risk averse children. Except for the father/daughter dyad risk seeking parents are more likely to have risk seeking offspring. Some gender differences were found. The association in parental and offspring time preference was larger for mothers than fathers. Daughters are more likely to be influenced by their mother’s risk preferences, however, sons are equally influenced by both parents. The results of this study suggest that the transmission in preferences is more nuanced than previously thought and parental gender may be important.     

Putting social preferences to work: Can revealed preferences predict real effort provision?

This paper presents a model of real effort provision in conjunction with rational social preference theory to predict how individuals exert effort to replace an exogenously determined “state of the world” with a preferred social outcome. Binary dictator games and real effort tasks are used to examine whether individuals exert effort in a manner that is consistent with their revealed preferences. The analysis of controlled laboratory experiments suggest that while individuals’ effort provisions are generally consistent with the theory, those who reveal relatively pro-social preferences fail to procure their “preferred” outcomes too frequently when the state of the world is highly inequitable in their favor. Consideration is given to alternative theories, namely ego depletion and cognitive dissonance, as potential explanations of social outcomes. There is evidence to suggest that dictators, on average, experience ego depletion which leads to a reduction in pro-social behavior through time.
