The role of data & program code archives in the future of economic research

This essay examines the role of data and program-code archives in making economic research "replicable." Replication of published results is recognized as an essential part of the scientific method. Yet, historically, both the "demand for" and "supply of" replicable results in economics has been minimal. "Respect for the scientific method" is not sufficient to motivate either economists or editors of professional journals to ensure the replicability of published results. We enumerate the costs and benefits of mandatory data and code archives, and argue that the benefits far exceed the costs. Progress has been made since the gloomy assessment of Dewald, Thursby and Anderson some twenty years ago in the American Economic Review, but much remains to be done before empirical economics ceases to be a "dismal science" when judged by the replicability of its published results.Econometrics ; Research

Knowledge withholding intentions in teams: the roles of normative conformity, affective bonding, rational choice and social cognition

The decision of members in a knowledge-intensive team to withhold their knowledge may threaten the performance of the team. To address the problem of knowledge resource risk in project teams, we maintain that it is important to understand why team members choose to withhold their knowledge, conceptualized as knowledge-withholding intention. In line with the literature on effort withholding, the research on multifoci relations between justice perceptions and social exchanges, and social cognitive theory, we proposed that the social exchange relationships that individuals form in the workplace, their perceptions of justice, and their knowledge withholding self-efficacy would influence their knowledge-withholding intentions. Through a survey of 227 information system development team workers, we found that all social exchange relationship variables had a significant impact on knowledge-withholding intentions. However, the justice perception variables only indirectly influenced knowledge-withholding intentions through the mediation of social exchange relationships. In addition, one of the task variables, task interdependence, influenced knowledge withholding intention through the mediation of knowledge withholding self-efficacy. Our results contribute to the knowledge management literature by providing a better understanding of the antecedents of knowledge withholding. We also offer suggestions for future research utilizing the framework of Kidwell and Bennett (1993) to study effort and knowledge withholding

How does risk mediate the ability of adolescents and adults with intellectual and developmental disabilities to live a normal life by using the Internet?

The focus of this position paper is Internet use by adolescents and adults with intellectual and developmental disabilities. Drawing on existing literature in the field we will identify problems with and gaps in the current research. Our review is framed by three main questions: What constitutes a ‘normal’ life for adolescents and adults with intellectual and developmental disabilities? What constitutes ‘normal’ use of the Internet for adolescents and adults with intellectual and developmental disabilities? How does risk mediate the ability of adolescents and adults with intellectual and developmental disabilities to live a normal life by using the Internet? The key focus of this review is the complex relationship between adolescents and adults with intellectual and developmental disabilities and those providing support; how they negotiate access to and use of the Internet and how perceptions regarding risk and normalcy mediate this negotiation. As a result of this review will argue that identified gaps and problems in the research field need to be addressed by expanding both methodological and conceptual approaches. In particular we will propose the need for more in-depth qualitative research that is inclusive in nature. We will also propose that an adapted positive risk-taking framework might be useful in framing the design, implementation and analysis of future research

Stigma in youth with Tourette's syndrome: a systematic review and synthesis

Tourette's syndrome (TS) is a childhood onset neurodevelopmental disorder, characterised by tics. To our knowledge, no systematic reviews exist which focus on examining the body of literature on stigma in association with children and adolescents with TS. The aim of the article is to provide a review of the existing research on (1) social stigma in relation to children and adolescents with TS, (2) self-stigma and (3) courtesy stigma in family members of youth with TS. Three electronic databases were searched: PsycINFO, PubMed and Web of Science. Seventeen empirical studies met the inclusion criteria. In relation to social stigma in rating their own beliefs and behavioural intentions, youth who did not have TS showed an unfavourable attitude towards individuals with TS in comparison to typically developing peers. Meanwhile, in their own narratives about their lives, young people with TS themselves described some form of devaluation from others as a response to their disorder. Self-degrading comments were denoted in a number of studies in which the children pointed out stereotypical views that they had adopted about themselves. Finally, as regards courtesy stigma, parents expressed guilt in relation to their children's condition and social alienation as a result of the disorder. Surprisingly, however, there is not one study that focuses primarily on stigma in relation to TS and further studies that examine the subject from the perspective of both the 'stigmatiser' and the recipient of stigma are warranted

Mechanisms Underlying Social Loafing in Technology Teams: An Empirical Analysis

Prior research has identified team size and dispersion as important antecedents of social loafing in technology-enabled teams. However, the underlying mechanisms through which team size and team dispersion cause individuals to engage in social loafing is significantly understudied and needs to be researched. To address this exigency, we use Bandura’s Theory of Moral Disengagement to explain why individuals under conditions of increasing team size and dispersion engage in social loafing behavior. We identify three mechanisms—advantageous comparison, displacement of responsibility and moral justification —that mediate the relationship between team size, dispersion and social loafing. Herein, we present the theory development and arguments for our hypotheses. We also present the initial findings from this study. Implications of the expected research findings are also discussed

Social dilemmas and shame-based sanctions: experimental results from rural Zimbabwe

Using two economic experiments I investigate how a sample of rural communities in Zimbabwe approach social dilemmas. When provided with an opportunity to impose sanctions in the context of a public goods game, fourteen out of eighteen communities achieved higher levels of cooperation. In thirteen communities the imposition of shame-based sanctions in the form of lighthearted criticism was observed. The resulting data revealed that: both non-cooperators and cooperators were criticised; community members cared about what their neighbours thought of them and made adjustments to their behaviour accordingly; the overall pattern rather than individual experiences of criticism affected subsequent behaviour; those who made low contributions and witnessed the criticism of others who made similar contributions, made higher contributions subsequently; while those who experienced such criticism first-hand made significantly smaller adjustments to their behaviour; those who made high contributions and witnessed the criticism of others who made similar contributions, made lower contributions subsequently; and to the extent that an opportunity to criticise passed by unexploited subsequent levels of cooperation were reduced.

Community Enforcement of Informal Contracts: Jewish Diamond Merchants in New York

The diamond industry is home to many unusual features: the predominance of an ethnically homogeneous community of merchants, the norm of intergenerational family businesses, and a rejection of public courts in favor of private contract enforcement. This paper explains that the diamond industry\u27s unique attributes arise specifically to meet the particularly rigorous hazards of transacting in diamonds. Since diamonds are portable, easily concealable, and extremely valuable, the risk associated with a credit sale can be especially costly. However, the industry enjoys valuable organizational efficiencies if transactions occur on credit between independent, fully incentivized agents. Thus, an efficient system of exchange will find ways to induce merchants who purchase on credit to fulfill their payment obligations. The very features that give the diamond industry an unusual profile are responsible for providing institutions to support credit sales. A system of private arbitration spreads information regarding merchants\u27 past dealings, so a reputation mechanism to monitor merchants can take hold. Intergenerational legacies, though restricting entry only to those who can inherit good reputations from family members, resolve an end-game problem and induce merchants to deal honestly through their very last transaction. And the participation of Ultra-Orthodox Jews, for whom inclusion and participation in their communities is equally paramount to their material wealth, serve important value-added services as diamond cutters and brokers without posing the threat of theft and flight

Invalid Forensic Science Testimony and Wrongful Convictions

This is the first study to explore the forensic science testimony by prosecution experts in the trials of innocent persons, all convicted of serious crimes, who were later exonerated by post-conviction DNA testing. Trial transcripts were sought for all 156 exonerees identified as having trial testimony by forensic analysts, of which 137 were located and reviewed. These trials most commonly included testimony concerning serological analysis and microscopic hair comparison, but some included bite mark, shoe print, soil, fiber, and fingerprint comparisons, and several included DNA testing. This study found that in the bulk of these trials of innocent defendants - 82 cases or 60% - forensic analysts called by the prosecution provided invalid testimony at trial - that is, testimony with conclusions misstating empirical data or wholly unsupported by empirical data. This was not the testimony of a mere handful of analysts: this set of trials included invalid testimony by 72 forensic analysts called by the prosecution and employed by 52 laboratories, practices, or hospitals from 25 states. Unfortunately, the adversarial process largely failed to police this invalid testimony. Defense counsel rarely cross-examined analysts concerning invalid testimony and rarely obtained experts of their own. In the few cases in which invalid forensic science was challenged, judges seldom provided relief. This evidence supports efforts to create scientific oversight mechanisms for reviewing forensic testimony and to develop clear scientific standards for written reports and testimony. The scientific community can through an official government entity promulgate standards to ensure the valid presentation of forensic science in criminal cases and thus the integrity and fairness of the criminal process
