Do what (you think) the rich will do: Inequality and belief heterogeneity in public good provision

Beliefs about others’ cooperativeness are among the strongest determinants of cooperative behaviours. Beliefs about different others, however, are not necessarily uniform, nor necessarily related to past behaviours: Different expectations about different others might solely originate from differences in observed individual characteristics. Finally, not all such beliefs need drive conditional behaviour alike.In a public good game with heterogeneous endowments, I find that rich subjects are expected to cooperate more by both rich and poor individuals, and that behaviours of both the rich and poor correlate only with beliefs about the rich. An intervention aimed at increasing perceived group cohesion has no impact on beliefs and mixed impacts on cooperation. I conclude with implications for information dissemination about uncooperative behaviour in the mass media and avenues for further research.     

Do you believe that others are more positional than you? Results from an empirical survey on positional concerns in France

We explore empirically the relevance of positional concerns in France. Unlike previous literature, we use two types of surveys, one addressed to a convenience sample, and the other to a random sample of French households living in the metropolitan area of Montpellier. Surveys are composed of a set of hypothetical questions related to several domains (income, education, vacation time, etc.). We also investigate whether individuals consider themselves more or less positional than others in society. Moreover, a set of variables that could potentially explain why people give positional answers is considered, such as being positional on a domain in which the individual excels. In addition to more conventional findings, we show that (i) the percentage of positional answers for each domain is about the same in the random and convenience samples, (ii) people consider others as more positional than themselves, and (iii) excelling in a given domain is not necessarily a good predictor of positional preferences in this domain.     

The role of reciprocation in social network formation,with an application to LiveJournal

This paper deals with the role of reciprocation in the formation of individuals’ social networks. We follow the activity of a panel of bloggers over more than a year and investigate the extent to which initiating a relation brings about its reciprocation. We adapt a standard capital investment model to study how reciprocation affects the build-up of the individual social capital of bloggers, as measured by their links and interactions with others. This allows us to measure the role of content production and relationship building in the dynamics of online social networks and to distinguish between the social networking and media aspects of blogging.     

How frequently do different voting rules encounter voting paradoxes in three-candidate elections?

We estimate the frequencies with which ten voting anomalies (ties and nine voting paradoxes) occur under 14 voting rules, using a statistical model that simulates voting situations that follow the same distribution as voting situations in actual elections. Thus the frequencies that we estimate from our simulated data are likely to be very close to the frequencies that would be observed in actual three-candidate elections. We find that two Condorcet-consistent voting rules do, the Black rule and the Nanson rule, encounter most paradoxes and ties less frequently than the other rules do, especially in elections with few voters. The Bucklin rule, the Plurality rule, and the Anti-plurality rule tend to perform worse than the other eleven rules, especially when the number of voters becomes large.     

Manipulability measures of common social choice functions

All social choice functions are manipulable when more than two alternatives are available. I evaluate the manipulability of the Borda count, plurality rule, minimax set, and uncovered set. Four measures of manipulability are defined and computed stochastically for small numbers of agents and alternatives.  Social choice rules derived from the minimax and uncovered sets are found to be relatively immune to manipulation whether a sole manipulating agent has complete knowledge or absolutely no knowledge of the preferences of the others. The Borda rule is especially manipulable if the manipulating agent has complete knowledge of the others. Received: 5 January 1996/Accepted: 31 July 1998     

SUSTAINABILITY OF THE FRIEDMAN RULE IN AN INTERNATIONAL MONETARY POLICY GAME

This article develops a two-country monetary economy model in order to analyze the international monetary policy game between governments and the domestic monetary policy game between each government and its private sector. We prove that if governments can commit to their own private sectors, the cooperative equilibrium of the game between governments is for them to follow the Friedman rule. When governments lack such ability to commit, we find that the Friedman rule is more likely to be sustained in our open-economy model than in the closed-economy model of Ireland.

Decision making for others involving risk: A review and meta-analysis

Are choices for others riskier than choices people make for themselves? This question has been asked by economists, psychologists, and other researchers in the social sciences – which has generated a diversity of research accounts and results. For example, a number of studies have found strong instances of a risky shift in choices for others, while other studies have found no such effect or have found that choices for others instead generate a cautious shift. In a meta-analysis of 128 effects from 71 published and unpublished papers (totaling 14,443 observations), we found a significant though small effect size (d = 0.105) in favor of a risky shift when people choose for others. Moreover, we found considerable variance between studies (Q = 1106.25), suggesting that the net effect is susceptible to moderating factors or study characteristics, which we identify and discuss as well (viz. choice recipient, decision frame, decision reciprocity, theoretical perspective, study design). Thus, we document not only whether decisions for others are riskier, but when (and when such decisions are less risky). We further discuss what is distinctly unique about decision making for others – how such choices are not just different in degree from personal choices but different in kind.     

Values and Vegetarianism: An Exploratory Analysis1

The American diet has changed substantially over the last few decades. These changes provide a test for social theory and have substantial effects on the demand for various food products, thus impacting U.S. agriculture. In this paper a rapidly growing dietary choice—vegetarianism—is explored. Prevalence of various forms of vegetarianism is estimated in a representative sample of a suburban population and factors that influence choice of a vegetarian diet are examined. About 7 percent of the sample report they are vegetarians. The prevalence of vegetarianism is not influenced by age, gender, or education, but individuals holding traditional values are less likely to be vegetarian than others. There also is some evidence mat individuals holding altruistic values are more likely than others to be vegetarians.     

Tracing risky decisions for oneself and others: The role of intuition and deliberation

This study contributes to the understanding of how individuals make choices for themselves and on behalf of others in a risky environment. In a laboratory eye-tracking experiment, we investigate whether risk preferences, decision error, and information processing differ between decisions made for oneself and on behalf of others. While we find no differences in risk preferences when deciding for oneself or for someone else, individuals have a greater decision error when deciding for others. Process data partly explains these differences. Individuals spend less time, have less fixations, and inspect less information when deciding for others. We detect similar processing patterns when comparing intuitive and deliberative decision making. We argue that the processing of decisions for oneself is more effortful and involves more extensive deliberation which, in turn, is related to less decision errors.     

Toddlers Help Anonymously

Young children are extremely motivated to help others, but it is not clear whether they do so in anonymous situations without social recognition. In two studies, we found that 18‐month‐old toddlers provided help equally in situations where an adult recipient was present and in situations where an adult recipient was not present. We included several control conditions to rule out that toddlers were simply unaware of their anonymity or were merely motivated to restore the physical order of things. Together, these findings suggest that early in ontogeny children are motivated to help others in need regardless of whether they can immediately be recognized for their prosocial intentions.     

Eye-Tracking Data: New Insights on Response Order Effects and Other Cognitive Shortcuts in Survey Responding

Survey researchers since Cannell have worried that respondents may take various shortcuts to reduce the effort needed to complete a survey. The evidence for such shortcuts is often indirect. For instance, preferences for earlier versus later response options have been interpreted as evidence that respondents do not read beyond the first few options. This is really only a hypothesis, however, that is not supported by direct evidence regarding the allocation of respondent attention. In the current study, we used a new method to more directly observe what respondents do and do not look at by recording their eye movements while they answered questions in a Web survey. The eye-tracking data indicate that respondents do in fact spend more time looking at the first few options in a list of response options than those at the end of the list; this helps explain their tendency to select the options presented first regardless of their content. In addition, the eye-tracking data reveal that respondents are reluctant to invest effort in reading definitions of survey concepts that are only a mouse click away or paying attention to initially hidden response options. It is clear from the eye-tracking data that some respondents are more prone to these and other cognitive shortcuts than others, providing relatively direct evidence for what had been suspected based on more conventional measures.     

Forensic psychiatric nursing. Discursive practices and the emergence of a specialty

1. While some authors argue that specialization is a threat to holistic nursing practice, others suggest that specialization is not only desirable and inevitable but should follow a rigorous process, including specific educational curriculum and examination procedures. 2. Two opposing views regarding forensic nursing are found in contemporary nursing literature. Some authors resist the discourse of specialization in nursing, while the discursive practices of others (e.g., leaders in forensic psychiatric nursing) could reflect a desire for power. 3. Using a poststructuralist approach, the controversy that has accompanied the development of forensic nursing through discursive practices is analyzed.     

Foundations in periods of political and economic uncertainty: The Latin American link and the Argentine case

Foundations — or proto-foundations — that had their roots in the western world in the Greek and Roman civilisations later found their way into ancient Spanish law. The early historical inheritance was transferred by Spain and Portugal to Latin America. Those first foundations were dedicated to a few activities in the areas of health, education and community services. In this article I briefly follow the transition from the traditional foundations to the contemporary one with their wider scope of activities. There is an attempt to follow the correspondence that may exist for the Argentine case between these foundations and extant theories that attempt to explain their role in a wider societal and economic context to conclude that the evidence is still limited for the various failure approaches discussed in the literature. Alternatively, we suggest that the retrenchment of the welfare state should be considered one of the factors that lead to the increase in the number of foundations and the diversification of their activities. The analysis incorporates the issue of discontinuities and crisis, and the strategies followed by different types of foundations under authoritarian rule and periods of high inflation. Surprisingly, during those periods the foundations continued to increase in numbers. I suggest that an adequate explanation for the dynamics of those foundations requires a socio-political approach complemented with the analysis of some economic factors.     

Numeracy and wealth

Numeracy is defined as the ability to understand and use numerical information. We examined the relationship between numeracy and wealth using a cross-sectional and a longitudinal study. For a sample of approximately 1000 Dutch adults, we found a statistically significant correlation between numeracy and wealth, even after controlling for differences in education, risk preferences, beliefs about future income, financial knowledge, need for cognition or seeking financial advice. Conditional on socio-demographic characteristics, our estimates suggest that on average a one-point increase in the numeracy score (11-point scale) of the respondent is associated with 5 percent more personal wealth. Additionally, we find that numeracy is a key determinant of the wealth accumulation trajectories that people follow over time. Over a 5-year period, while participants with low numeracy decumulate wealth, participants with high numeracy maintain a constant positive level of wealth.     

Choice rules with fuzzy preferences: Some characterizations

Consider an agent with fuzzy preferences. This agent, however, has to make exact choices when faced with different feasible sets of alternatives. What rule does he follow in making such choices? This paper provides an axiomatic characterization of a class of binary choice rules called the α satisfying rule. When α=1, this rule is the Orlovsky choice rule. On the other hand, for α≤1/2, the rule coincides with the M _α rule that has been extensively analyzed in the literature on fuzzy preferences. Received: 3 August 1995/Accepted: 19 November 1997     

The Development of Gaze Following in a Third‐Party Context

Infants follow the gaze of an individual with whom they are directly interacting by the end of the first year. By 18 months infants are capable of learning novel words in observational (or third‐party) contexts (Floor & Akhtar, 2006). To examine third‐party gaze following in 12‐ and 18‐month‐olds, the parent and experimenter engaged in a conversation while the infant was present. For 8 trials approximately every 30 sec the experimenter would turn her head to the right or left to fixate on a toy placed on either side of the room with the parent following suit. In the first experiment, the parent was seated next to the infant and the experimenter opposite, whereas in the second experiment the positions of the adults were switched. In Experiment 1, 18‐month‐olds but not 12‐month‐olds followed gaze. In Experiment 2, 12‐month‐olds acquired a tendency to follow gaze during the experimental session. These results suggest that an incipient ability to follow third‐party gaze is present by 12 months and that infants acquire a more reliable and general ability to follow the gaze of noninteractive others between 12 and 18 months.     

Goldhagen's Hitler's Willing Executioners: A Clarification and Methodological Critique

Daniel Jonah Goldhagen's Hitler's Willing Executioners has sparked an outpouring of controversy in the international and scholarly press. Unfortunately, much of the debate over the book has been focused on a simplistic interpretation of Goldhagen's argument. In this article, we seek to move the debate in a more fruitful direction by clarifying Goldhagen's actual argument, and then critiquing this argument, not the simplified one presented in much of the literature. We suggest that key parts of Goldhagen's argument cannot be falsified by empirical evidence and thus should be regarded much more cautiously and tentatively than Goldhagen's firm conclusions suggest. Nevertheless, we commend Goldhagen for developing a methodologically explicit causal analysis of the Holocaust and encourage others to follow this example.     

The Politics of Home: Dual Citizenship and the African Diaspora1

In recent decades, more countries have started to recognize dual citizenship. Although overlooked in the literature, Africa is part of this trend with more than half of its governments now permitting their nationals to naturalize elsewhere while retaining home country rights. Why have some African countries embraced dual citizenship for emigrants, while others have not? We examine demographic, political, and economic data broadly across the continent and identify few clear patterns. We then explore the cases of Senegal, Ghana, and Kenya, finding that dual citizenship policies are driven as much by politics as they are by economic or security concerns.     

Robustness of optimal decision rules where one of the team members is exceptionally qualified

This work investigates the robustness of optimal decision rules under a changing size of a decision group where the competence of one member is outstanding while the others possess an identical competence. More specifically, we focus on the expert rule, the almost expert rule and the tie-breaking chairperson rule. We first establish criteria for the optimality of each of these rules and then use it to investigate their robustness. Robustness is an important property of decision rules, especially when cost of adjustment to a new rule is high. Our findings are that the expert rule and the chairperson rule are robust while the almost expert rule is not.

Tax morale and fairness in conflict an experiment

Most people pay their taxes most of the time, even if the expected disutility from enforcement is too low to deter tax evasion. One potential reason is tax morale and, more specifically, rule following. In a lab experiment, we show that the willingness to pay taxes just because participants are told they are supposed to pay is indeed pronounced. Yet compliance is reduced if participants learn that income is heterogeneous. The effect is driven by participants with the lowest income. The reduction obtains irrespective of the tax regime. If the tax is proportional to income, or progressive, participants become more skeptical about the willingness of participants with high income to comply.
