Social comparison and risky choices

Theories (and experiments) on decision making under risk typically ignore (and exclude) a social context. We explore whether this omission is detrimental. To do so we experimentally investigate the simplest possible situation with both social comparison and risk: participants choose between two lotteries while a referent faces a fixed payoff. Participants are more risk averse when they can earn at most as much as their referent (loss situation) than when they are ensured they will earn at least as much as their referent (gain situation). Prospect theory with a social reference point would predict the exact opposite behavior. These results show that straightforward extensions of existing theories to allow for social comparison do not provide accurate predictions.     

Sex-specific effects of interventions that extend fly life span

Genetic and environmental interventions that extend life span are a current focus in research on the biology of aging. Most of this work has focused on differences among genotypes and species. A recent study on fruit flies shows that life span extension because of dietary restriction can be highly sex-specific. Here we review the literature on sex-specific effects of 56 genetic and 41 environmental interventions that extend life span in Drosophila melanogaster. We found that only one-sixth of the experiments provided statistical tests of differences in response between males and females, suggesting that sex-specific effects have been largely ignored. When measured, the life span extension was female-biased in 8 of 16 cases, male-biased in 5 of 16 cases, and not significantly different in only 3 of 16 cases. We discuss possible explanations for the sex-specific differences and suggest various ways in which we might test these hypotheses. We argue that understanding sex differences in the response to life span-extending manipulations should lead to new insights about the basic mechanisms that underlie the biology of aging in both sexes.     

Metaphors and Theory Building in Organization Theory: What Determines the Impact of a Metaphor on Theory?*

A long‐standing stream of organizational research suggests that our ability to theorize and reason about organizations is significantly influenced by metaphorical representations of organizations. This study contributes to this research stream by examining how different metaphors influence theory development and academic thinking about organizations. We asked scholars from UK business schools to rate different metaphors in terms of their impact on theory building. We then examined whether, and to what extent, these metaphors (after they had been selected) had helped in clarifying and advancing their understanding of organizations. The results indicate that the ability of a metaphor to advance and clarify theoretical understandings of organizations is based upon (1) the degree to which that metaphor is seen to capture multiple salient features of organizations and (2) the ease with which the metaphor is understood. We discuss the implications of these results for theorizing and research on organizations.     

Can TV shows promote acceptance of sexual and ethnic minorities? A literature review of television effects on diversity attitudes

Until recently, western TV programming rarely featured sexual or ethnic minority members; if present, their representation was mostly negative. Increasingly, though, diverse characters start to play likeable protagonists as well. Thus, television can promote negative diversity attitudes and, at other times, positive ones. The present article reviews and connects theories and research from sociology, psychology, and media and communication studies to clarify the role of television in diversity attitudes formation and to identify directions for future research. Specifically, two research questions are addressed. First, through which processes does television influence diversity attitudes? Second, what features of TV shows contribute to positive diversity attitudes formation among viewers, according to different theories of television effects? Findings indicate that television can entrench existing negative diversity attitudes through the echo chamber phenomenon. However, TV content featuring numerous, likeable, attractive, and typical minority characters that have friendly interactions with the rest of society can promote positive diversity attitudes. Future research should study openness to view content with minority characters, examine the effects of the complete video media diets, check media effects in non-western countries, explore media effects in longitudinal studies and investigate what constitutes attractive, likeable, and typical representation of ethnic and sexual minorities.     

Comparing Immigration Policies: An Overview from the IMPALA Database

This paper introduces a method and preliminary findings from a database that systematically measures the character and stringency of immigration policies. Based on the selection of that data for nine countries between 1999 and 2008, we challenge the idea that any one country is systematically the most or least restrictive toward admissions. The data also reveal trends toward more complex and, often, more restrictive regulation since the 1990s, as well as differential treatment of groups, such as lower requirements for highly skilled than low‐skilled labor migrants. These patterns illustrate the IMPALA data and methods but are also of intrinsic importance to understanding immigration regulation.

Anti-corporate movements and public relations

This paper develops a theoretical framework of the anti-corporate movement. We argue that previous accounts in the public relations literature, including theorizing around stakeholders, publics, activist groups and issues management, are limited and provide only a partial conceptualization of anti-corporate movements. In order to address this shortcoming, we draw upon social movements theory to develop a grounded and enriched theoretical framework of anti-corporate movements.     

Social Identity,Organizational Identity and Corporate Identity: Towards an Integrated Understanding of Processes,Patternings and Products

This paper provides an overview of previous work that has explored issues of social, organizational and corporate identity. Differences in the form and focus of research into these three topics are noted. Social identity work generally examines issues of cognitive process and structure; organizational identity research tends to address the patterning of shared meanings; studies of corporate identity tend to focus on products that communicate a specific image. Nonetheless, across these areas there is general consensus that collective identities are (a) made viable by their positivity and distinctiveness, (b) fluid, (c) a basis for shared perceptions and action, (d) strategically created and managed, (e) qualitatively different from individual identities and (f) the basis for material outcomes and products. This paper calls for greater cross‐fertilization of the three identity literatures and discusses requirements for the integration of micro‐ and macro‐level analyses.     

Who should invest in specific training?

We study experimentally whether employers or workers should invest in specific training. Workers have an alternative trading opportunity that takes the form of either an outside option or a threat point. Theory predicts that with outside options, employers have (weakly) better investment incentives than workers do and should therefore be the investing party. With threat points, employers and workers are predicted to invest the same. Our results are, by and large, in line with these predictions. Due to offsetting inefficiencies in the bargaining stage, however, realized inefficiencies are remarkably similar across the different situations considered.

The need for marriage contracts: An experimental study

A spouse who invests in relationship specific human capital enlarges the size of a couples total surplus. Such investments typically also weaken the outside opportunities of the specializing spouse and thereby her bargaining position. Realizing this, underinvestment in relationship specific human capital may result. This reduces the couples potential surplus. Private or public marriage contracts can stipulate conditions to solve this holdup underinvestment problem. This paper reports about an experiment that addresses the practical relevance of this problem. We find that although underinvestment in home production occurs, it is less frequent than game theory predicts. That is: players are prepared to specialize in home production when backwards induction predicts them not to do so. Furthermore, we find that the non-investing spouses are less opportunistic towards their partners when the large surplus has been created by the spouse than when the size of the surplus is determined exogenously.We gratefully acknowledge valuable comments from Theo Offerman, Randolph Sloof, from seminar participants in Amesterdam and Mannheim and from an anonymous referee.
