Vertrauen und Reputationseffekte bei Internet-Auktionen

In internet auctions the exchange between two anonymous actors corresponds to a one-shot prisoner’s-dilemma-like situation. In such a situation there is a high risk that both actors will cheat and that the market will collapse. The solution to attaining mutual cooperation is the simple and very efficient institution of a public rating system. By this institution sellers have an incentive to invest in reputation in order to enhance future chances of business. Using data from about 200 auctions of mobile phones we analyse the effects of the reputation system by empirical methods. In general the analysis of non-obtrusive data from auctions may help to gain a deeper understanding of basic social processes of exchange, reputation, trust, and cooperation and of the impact of institutions on the efficiency of markets. In this study we report empirical estimations of the effects of reputation on characteristics of transactions like the probability of a successful deal, the mode of payment, and the largest bid or auction price. Particularly, we ask whether sellers receive a “premium” for reputation. Results show that buyers are ready to pay higher prices for reputation to diminish the risk of exploitation. On the other hand, sellers protect themselves against cheating by choosing of a proper mode of payment. Simple institutional settings lead to cooperation, relatively rare events of fraud, and efficient markets despite the risk of mutual opportunistic behavior.     

Reputation und Kooperation

The institutionalized system of rating sellers in internet-auctions is a powerful tool to promote cooperation. This system encourages rational actors to “invest in reputation” and, consequently, to behave cooperatively. We analyze the strategic behaviour of sellers and buyers and, particularly, we investigate with empirical data whether there is a “premium on reputation”. Ulrich Brinkmann and Matthias Meifert critically comment on our article. In this rejoinder we discuss their objections and particularly the measurement of reputation. Also, we explore the question of the relevance of an institutionalized system of reputation. Is an exogeneous sanctioning mechanism a necessary prerequisite to generate a stable amount of cooperation as Brinkmann and Meifert argue or does the institution of a reputation system suffice? To answer this question further experimental or simulation studies are required.     

Thinking and Working Politically: Learning from practice. Overview to Special Issue

Over the last 15 years, a set of ideas now referred to as “thinking and working politically” (TWP) has coalesced into a “second orthodoxy” about how to take context into account when implementing development interventions. This approach stresses the importance of obtaining a better understanding of the local context (“thinking politically”) in order to support local actors to bring about sustainable developmental change (“working politically”). However, the evidence base to justify this new approach remains thin, despite a growing number of programmes which purport to be implementing it. Officials in development agencies struggle with putting it into practice and it is unclear how TWP differs—or not—from similar approaches, such as Problem Driven Iterative Adaptation (PDIA) and Doing Development Differently (DDD). This Special Issue sheds light on what TWP means in practice by examining a set of initiatives undertaken by both development partners and government departments in Nigeria, the Occupied Palestinian Territories, China and India. This overview article outlines, in brief, each of the Special Issue's four papers and then draws out five lessons—for funders and for practitioners—from across all the papers. Our five lessons are: (1) the fundamental importance of undertaking political economy analysis (PEA) to adapt programmes to their contexts; (2) the importance of having a realistic level of ambition for interventions; (3) the need to support local ownership—not just “agreement ownership” (between a donor agency and government) or local “management ownership” of the programme, but critically “driver ownership” by generating trust with the key local actors driving change; (4) the need for a more effective set of tools for measuring results in complex programmes that attempt to achieve improvements in long‐run governance; and, (5) that although the political economy of donors is often seen as a barrier to applying TWP, the articles show how much can be done with a TWP approach if the analysis takes into account the political economy of donors as well as that of the local context. We conclude with a set of operational recommendations for donors and implementors, as well as suggestions of avenues for further research.     

Studies of Scholarly Productivity in Social Work Using Citation Analysis

Ideally, an educator’s reputation should be based primarily on that person’s scholarly publications. However, reputation is more than the sum of one’s scholarly efforts. In this article, the authors seek to add objective information to the subjective decision-making process involved in hiring, promoting, or providing tenure to educators. The authors present norms of citations—objective indicators of reputation—for professors, associate professors, and assistant professors. These norms were derived from the Citation Index of the Social Sciences Citation Index (SSCI). Four studies were undertaken to examine scholarly productivity using the same basic methodology: citation analysis. In Study 1, the authors examined a sample of educators listed in the Encyclopedia of Social Work. These experts were used as a national norm against which other educators could compare themselves. Study 2 was based on a citation analysis of deans of all graduate schools of social work. In Study 3, the authors examined “local norms” of four particular schools of social work and discussed the differences between national and local norms. In Study 4, the authors examined “personal norms” through a detailed study of the careers of three individual professors, and compared their entirely scholarly productions against the SSCI record.     

The free encyclopedia that anyone can dispute: An analysis of the micro-structural dynamics of positive and negative relations in the production of contentious Wikipedia articles

We consider two rival hypotheses on the emergence of organization in open production communities. According to the first (“reputation hypothesis”), patterns of agreement and disagreement among participants in open production communities are explained by differences in individual reputation for quality of contribution. The reputation hypothesis predicts that participants will tend to agree with more reputable others and disagree with less reputable others thus contributing to establish a stable open production community. According to the second hypothesis (“balance hypothesis”), patterns of agreement and disagreement are explained by membership in sub-communities of “friends” and “enemies.” The balance hypothesis predicts that participants in open production communities will agree mainly with friends and disagree mainly with enemies, regardless of considerations about reputation for the quality of their contributions. In this paper, we examine which one of these hypotheses is more consistent with patterns of positive and negative interaction events observed during the production of the complete set of 1,206 English-language Wikipedia articles officially considered controversial. We specify and estimate new models for signed and weighted relational event networks predicting the probability that a user deletes the contributions of another user – thus expressing personal disagreement – and/or protects the contributions of another user against deletion from third parties – thus expressing personal agreement. In an analysis of positive and negative interaction among Wikipedia contributors consisting of more than 60 million observations, we find strong support for the balance hypothesis and for the predictions of the reputation hypothesis that are more consistent with alter-centric interpretations of social status as conferred by alters through observable acts of deference.     

Pregnant Women's Experiences of Crisis Pregnancy Centers: When Abortion Stigmatization Succeeds and Fails

There is broad consensus that abortion is stigmatized, but the role of interpersonal interaction in this process is underspecified. I examine interviews with 25 women in the United States who visited crisis pregnancy centers (CPCs)—antiabortion organizations that offer one‐on‐one “prolife counseling”—for how and when interactions matter for abortion stigmatization. I identify two primary ways CPC counselors stigmatized abortion and describe variation in their impact: counselors' efforts were “successful,” were misrecognized as ideologically‐neutral, or were resisted. The findings demonstrate the importance of women's current consideration of abortion and preexisting beliefs for understanding how interpersonal interactions contribute to abortion stigma.     

Reputation management: the new face of corporate public relations?

An empirical study of Fortune 500 companies suggests that “reputation management” is gaining ground as a driving philosophy behind corporate public relations. Whether the phenomenon is a trend or a fad is not clear, given the lack of consensus in defining reputation, the instability and questionable validity of reputation measures, and unanswered questions about when and how (or even whether) reputation can be “managed.” Besides reputation management, corporate public relations departments in the study embraced a wide variety of other definitions of their function, suggesting that public relations continues to have great difficulty in defining itself. While the study did not find a strong correlation between reputation and overall spending on corporate communication activities, as had a similar study the prior year, it did find some interesting correlations between reputation and specific categories of spending.     

The Phenomenon Of The Public Wife: An Exercise In Goffman's Impression Management*

Approaching the topic of American leader-image from the perspective of politics-as-theater (political communication as exchange of symbols), this paper examines a taken-for-granted visual symbol which a national political leader is invariably expected to present: a wife. Her contributions to her husband's “impression management” techniques (Goffman, 1959) are studied in Goffman's “defensive” categories of dramaturgical loyalty, dramaturgical discipline, and dramaturgical circumspection. This analysis suggests that the visible presence of a wife in public leadership rituals offers the public voter or viewer important reassurances or symbolic guarantees about her husband's “morality”—and, therefore, his appropriateness for public trust. She has become a necessary partof his public performance because of our everyday need for “cultural absolutes” (Furay, 1977) in the image of our leadership figures.     

BAD REPUTATION UNDER BOUNDED AND FADING MEMORY

I relax the full memory assumption in Ely and Välimäki's (2003) mechanic game, where reputation is bad. Under bounded memory (only recent periods are observed), long memory still yields bad reputation due to an “echo” where bad signals cause future motorists to not hire, causing further lack of hiring, and so on. Short memory avoids bad reputation by making it “useless,” because consumers never learn enough information to change their decisions. No “happy middle” exists under bounded memory where consumers learn valuable information without tempting the mechanic into harmful signaling and thereby unraveling the market. By contrast, “fading memory” (past periods are randomly sampled with “fading” probabilities) achieves this happy middle by offering valuable information in a way that bounds the probabilities of these reputational echoes. Possible fading memory implementations (e.g., for review websites) are described and generalized to a broader class of games. (JEL C73, D8)     

COMMUNICATING THREAT: The Canadian State and Terrorism

Canada's position vis‐à‐vis September 11 differs substantially from the United States’ in both circumstance and rhetoric. Although Canada was not the target of the terrorist attack, the United States is Canada's closest neighbor. In the words of the Prime Minister in the weeks following September 11, the United States is “more like family than friends.” Given this, how has the terrorist threat been interpreted for and communicated to the public by the Canadian state? Through ethnographic content analyses of the documents (speeches and press releases) found on the Prime Minister's Office (PMO) Web site, we consider the communications by the Canadian state with respect to the events of September 11. We analyze this information within the overarching frameworks of risk and trust. In terms of risk, we examine the Prime Minister's communications and the framing of this communication as it relates to the discourse of probable harm and/or benefit. As for trust, we consider the emphasis on reputation and how this affects the information provided and its delivery. These risk/trust underpinnings speak to the Canadian state's construction of security, security threats, and the construction of the Canadian state more generally.     

Campus Sex in Context: Organizational Cultures and Women's Engagement in Sexual Relationships on Two American College Campuses

An “inhabited” approach to the study of institutions examines how organizational actors produce locally distinctive meaning in response to similar institutional forces. Adopting inhabited institutionalism to the study of campus sexual life, this study draws on interviews with 54 undergraduate women at two four‐year universities in the United States—Ivy U and State U—to show campus cultures unique to a university inform women's decisions to engage in hookups and/or relationships. For women attending Ivy U, an elite institution where pressure to succeed is palpable, both hookups and long‐distance relationships alike are posited as advantageous for the time‐crunched, preprofessional student. At State U, a public school with a party reputation, women explain their engagement in hookups as part of the “fun” of college life, while women seeking or involved in committed relationships are obligated to negotiate the effects of the party culture in their partnerships. This study challenges the notion of a monolithic sexual culture across university settings by showing how campus cultures cultivated at the local level create unique organizational conditions within which undergraduate women forge and explain their engagement in hookups and relationships alike.     

Diversity Regimes in Worker Cooperatives: Workplace Inequality under Conditions of Worker Control

Two major shifts in contemporary work organizations—“employee participation” and “diversity management”—have typically been studied in isolation from one another. Building on theoretical work by Acker (2006a,b), we ask how the interaction of these two constructs has affected the pursuit of workplace democracy at two worker cooperatives in Northern California. Using qualitative methods, we find that distinct “diversity regimes” have emerged at these establishments, substantially affecting the configurations of inequality that evolved. We distinguish two types of diversity regimes—“utilitarian” and “communitarian”—which operate either to obscure the workings of inequality or to foster attention to their presence. Our results suggest that how sociodemographic differences are managed has material consequences for the development of egalitarian structures at work.     

A Chronological Bibliography of the College Novel

Abstract

Although Muslims in the United States are highly assimilated into American society, they represent less than 1 percent of the total population. Therefore, most of the information Americans receive about this group comes from secondary sources. Two theoretical perspectives of opinion formation—image of God and low information rationality—shed light on the subject of trust in this marginalized group. For highly religious Americans, nearly two-thirds of the 2005 Baylor Religion Survey's national sample, Muslims may represent the ultimate outsiders. We compare the effect of the central religious narrative, or an image of God as creator or judge, to the effect of political ideology, or the likely exposure to forms of low information rationality such as framing, spinning, and buzzwords. We use indicators of these concepts in a multivariate analysis of trust in Muslims as a test of these competing perspectives of opinion formation. Using the 2005 Baylor Religion Survey data, we find that not only does trust in Muslims decrease with both a more conservative political ideology and a stronger view of God as vengeful and angry but that these effects interact to produce individuals who are far less likely to trust Muslims compared to their Democrat, Independent, and “loving God” counterparts.     

The Illusions and Juxtapositions of Commercial Sexual Exploitation among Youth: Identifying Effective Street-Outreach Strategies

To explore sexually exploited youths' perspectives of how street outreach workers can effectively provide outreach and connections to services, we conducted qualitative interviews with 13 female participants, ages 14 to 22, in a Midwest U.S. city. Participants reported multiple types of exploitation, most first exploited by age 13, plus substance use and recurrent homelessness. Nearly all had a pimp, and all used the internet as a venue for sexual exploitation. Participants wanted outreach workers to use “soft words” to refer to exploitation. They expressed contradictory images of their “boyfriend” pimps and their exploitation. They wanted outreach workers to “provide resources,” “be nonjudgmental,” “listen,” and “care.” Street outreach can be one way to support sexually exploited youth but should occur in multiple settings.     

INVESTMENT CHOICE ARCHITECTURE IN TRUST GAMES: WHEN “ALL‐IN” IS NOT ENOUGH

While many economic interactions feature “All‐or‐Nothing” options nudging investors towards going “all‐in,” such designs may unintentionally affect reciprocity. We manipulate the investor's action space in two versions of the “trust game.” In one version investors can invest either “all” their endowment or “nothing.” In the other version, they can invest any amount of the endowment. Consistent with our intentions‐based model, we show that “all‐or‐nothing” designs coax more investment but limit investors' demonstrability of intended trust. As a result, “all‐in” investors are less generously reciprocated than when they can invest any amount, where full investments are a clearer signal of trustworthiness. (JEL C72, C90, C91, D63, D64, L51)     

Responding to a Health Crisis on Facebook: The Effects of Response Timing and Message Appeal

This study examined the effects of timing and message appeal of a crisis response on organizational perceptions and behavioral intentions on social media. Using a health crisis scenario, a 3 (one hour vs. one day vs. one week after the crisis) × 2 (emotional vs. rational appeal) between-subjects experiment (N = 502) found that a crisis response posted one day after the crisis on Facebook elicited greater trust towards the hospital in crisis compared to a response posted in one week. The one-hour response and one-day response did not show differential effects on trust towards the hospital. The effect of timing was mediated by perceived credibility of the crisis response. In addition, the emotional appeal triggered greater trust, perception of reputation, and intention to “like” the post; whereas the rational appeal elicited greater intention to share and comment on the post. The study provides both theoretical and practical implications.     

Newborns' Cries are Unique to Individuals (But Not to Language Environment)

Human neonates exhibit individually distinctive patterns of variation—sometimes called cry “signatures”—in the acoustics of their cries. For tests of group differences (e.g., age, health status, or ambient language differences), the uniqueness of cry sounds to individuals means that multiple cries from same infant cannot appropriately be treated as independent events for analysis. This approach violates the assumption of independence that underlies many statistical techniques and runs the risk of uncovering “significant” group effects that do not actually exist. Nonetheless, publications continue to appear in which multiple cries from the same infant have been treated as independent events for analysis. To demonstrate the perils, we have compared the cries of infants born into a Mandarin Chinese language environment with cries of infants born into an American English language environment. We show (1) that treating each cry sound as an independent event yields numerous “significant” group effects and (2) that these effects all but disappear when cries are treated appropriately, as “nested” within individual infants. The latter outcome is in keeping with prevailing models of neonatal cry production and casts doubt on the claim that neonates alter their cries to match features of the language spoken in their environment.     

Dancing with discrimination: managing stigma and identity

Fans are a group that are stigmatized and discredited, at least to some degree, by their “deviant” and common form of symbolic consumption. At stake in the process of stigmatization is the very identity of the individual fan, and their symbolic and emotional well‐being. This paper reports on an empirical study of one particular group of fans—Star Trek fans (or “Trekkies”)—and explores the complex identity issues articulated by them as they “manage” their problematic public identity. Drawing upon interviews conducted with 18 Trekkies, the article describes how this stigmatic identity is organized within a disciplinary matrix that operates at a micro level through two key processes: humour and self‐surveillance. In particular, we highlight their struggle with the dilemmas of exposing their private “fandom” in a public context, and the highly ambivalent manner in which they seek to escape stigmatization.     

Where do we stand? Recent AEA member views on professionalization

The professionalization of evaluation continues to be debated at numerous conferences in the U.S. and abroad. At this time, AEA member views on the potential benefits and negative side effects of professionalization are essential as the discussion evolves. This study provides recent views on major topics in professionalization, including potential benefits, negative side effects, processes, competencies, and procedures. Results from in-depth interviews and an online survey demonstrate that AEA members view potential benefits of professionalization to be stakeholder trust, evaluator reputation and identity, while concerns about a potential negative side effect known as the “narrowing effect” (i.e., some evaluators will be alienated based on their background, competencies, etc.) were expressed by participants. These recent findings can inform the ongoing discussion of professionalization, and suggest new directions for future research on evaluation.     

Group Decision by Consensus: Reaching Unity in the Society of Friends1

For over 300 years the members of the Society of Friends (Quakers) have been making group decisions without voting. Their method is to find a ”sense of the meeting’which represents a consensus of those involved. Ideally this consensus is not simply “unanimity,” or an opinion on which all members happen to agree, but a “unity”: a higher truth which grows from the consideration of divergent opinions and unites them all. Friends can “unite” in support of action which shows due consideration to the individuality of each member and to their corporate concerns. As an illustration of this method, we will analyze in some detail the group process of a Quaker committee as it worked with a difficult social problem over a period of one year. Before beginning the analysis, we will summarize some of the main points in the process of reaching the “sense of the meeting” as it has been described by Friends and others. Also we will review the functional theory of social interaction which will provide the basis for theoretical analysis.
