Altruism or diminishing marginal utility?
No full textWe challenge a commonly used assumption in the literature on social preferences and show that this assumption leads to significantly biased estimates of the social preference parameter. Using Monte Carlo simulations, we demonstrate that the literature’s common restrictions on the curvature of the decision-makers utility function can dramatically bias the altruism parameter. We show that this is particularly problematic when comparing altruism between groups with well-documented differences in risk aversion or diminishing marginal utility, i.e., men versus women, giving motivated by pure versus warm glow motives, and wealthy versus poor. We conclude by proposing two approaches to address this bias
Self-serving dishonesty: The role of confidence in driving dishonesty
No full textAmbiguity and uncertainty as an explanation for ethical blind spots is well-documented. We contribute to this line of research by showing that these blind spots arise even when there is naturally occurring uncertainty—that is, when individuals are simply uncertain of the truth they “fill-in” this uncertainty in a self-serving way. To examine self-serving dishonesty, we asked a sample of U.S. car owners to respond to an auto insurance underwriting questionnaire that affects their price of insurance (i.e., premium), and investigated how financial incentives affect the honesty of their responses. We find, consistent with the current literature, that people have a strong preference for truthfulness, but only when they are confident of the objective truth. However, when people are not completely certain of the objectively correct answer, significant dishonesty occurs in a self-serving manner. We also find that reports of confidence do not depend on incentives and thus self-serving dishonesty is not strategic
Waiting to give: Revealed versus stated preferences
No full textWe estimate and compare the effect of increased time costs on consumer satisfaction and behavior. We are able to move beyond the existing literature, which focuses on satisfaction and intention, and estimate the effect of waiting time on return behavior. Further, we do so in a prosocial context and our measure of cost is the length of time a blood donor spends waiting. We find that relying on satisfaction data masks important time cost sensitivities; namely, it is not how the donor feels about the wait time that matters for return behavior, but rather the actual duration of the wait. Consistent with theory we develop, our results indicate that waiting has a significant longer-term social cost: we estimate that a 38% increase (equivalent to one standard deviation) in the average wait would result in a 10% decrease in donations per year
Using Experimental Economics to Measure the Effects of a Natural Educational Experiment on Altruism
No full textEconomic research examining how educational intervention programs affect primary and secondary schooling focuses largely on test scores although the interventions can affect many other outcomes. This paper examines how an educational intervention, a voucher program, affected students' altruism. The voucher program used a lottery to allocate scholarships among low-income applicant families with children in K-8th grade. By exploiting the lottery to identify the voucher effects, and using experimental economic methods, we measure the effects of the intervention on children's altruism. We also measure the voucher program's effects on parents' altruism and several academic outcomes including test scores. We find that the educational intervention positively affects students' altruism towards charitable organizations but not towards their peers. We fail to find statistically significant effects of the vouchers on parents' altruism or test scores.
Increasing autonomy in charitable giving: The effect of choosing the number of recipients on donations
No full textIn many contexts people can choose how many charities to help. This paper presents results from a
laboratory experiment that varies whether the subjects have a choice in the number of charities to
donate to and whether they are given an option to opt out. We find that the choice increases donation
frequency, but does not influence donation amounts. If the choice also includes the opt-out option,
there is no increase in the donation frequency or amount
Altruism among consumers as donors
No full textLike most charitable and non-profit organizations, the arts, cultural institutions and universities often ask individuals for financial gifts to help fund their operations. However, a key difference is that the individuals who are solicited for charitable donations by arts and cultural institutions are oftentimes also purchasing services from the same institution. Thus, an open question is whether, and how, individuals make trade-offs between charitable gifts and consumer purchases from the same institution. We investigate this question in an online experiment that asks Sydneysiders to make a series of decisions between donating to the iconic Sydney Opera House, purchasing merchandise from the Sydney Opera House and keeping money. Our findings show that demand for SOH merchandise and SOH donations are substitutes. Further, we find evidence that increasing the individuals’ awareness of the substitutability between money received from donations and money received from the sale of merchandise, increases the cross-price elasticity. This is particularly true for those individuals who positively identify with the Opera House. Our results suggest that the unique nature of arts, cultural and educational institutions as recipients of donations and providers of services mean that fundraising among “patrons” may crowd-in additional revenue
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
