Affirmative action in education: Evidence from engineering college admissions in India

This paper examines an affirmative action program for “lower-caste” groups in engineering colleges in India. We study both the targeting properties of the program, and its implications for labor market outcomes. We find that affirmative action successfully targets the financially disadvantaged: the upper-caste applicants that are displaced by affirmative action come from a richer economic background than the lower-caste applicants that are displacing them. Targeting by caste, however, may lead to the exclusion of other disadvantaged groups. For example, caste-based targeting reduces the overall number of females entering engineering colleges. We find that despite poor entrance exam scores, lower-caste entrants obtain a positive return to admission. Our estimates, however, also suggest that these gains may come at an absolute cost because the income losses experienced by displaced upper-caste applicants are larger than the income gains experienced by displacing lower-caste students. Limited sample sizes in our preferred econometric specifications, however, prevent us from drawing strong conclusions from these labor market findings.     

When Does a Platform Create Value by Limiting Choice?

We present a theory for why it might be rational for a platform to limit the number of applications available on it. Our model is based on the observation that even if users prefer application variety, applications often also exhibit direct network effects. When there are direct network effects, users prefer to consume the same applications to benefit from consumption complementarities. We show that the combination of preference for variety and consumption complementarities gives rise to (i) a commons problem (to better satisfy their individual preference for variety, users have an incentive to consume more applications than the number that maximizes joint utility); (ii) an equilibrium selection problem (consumption complementarities often lead to multiple equilibria, which result in different utility levels for the users); and (iii) a coordination problem (lacking perfect foresight, it is unlikely that users will end up buying the same set of applications). The analysis shows that the platform can resolve these problems and create value by limiting the number of applications available. By limiting choice, the platform may create new equilibria (including the allocation that maximizes users' utility); eliminate equilibria that give lower utility to the users; and reduce the severity of the coordination problem faced by users.     

Writing Across Contexts: Urban Informality and the State in Tallinn,Bafatá and Berlin

Urban research has long related informality to a lack of state capacity or a failure of institutions. This assumption not only fails to account for the heterogeneous institutional relations in which informality is embedded, but has also created a dividing line between states. Whereas some states are understood to manage urban development through functioning institutions, others, in this view, fail to regulate. To deconstruct such understandings, this article explores informal practices through a multi‐sited individualizing comparison between three case studies of water governance, parking regulation and dwelling regimes in Bafatá (Guinea‐Bissau), Tallinn (Estonia) and Berlin (Germany), respectively. Our approach to understanding informality starts from the negotiation and contestation of order between differently positioned actors in the continuous making of states. From this point of view, informality is inherent in the architecture of states––emerging through legal systems, embedded in negotiations between and within institutions, and based on conflicts between state regulations and prevailing norms. Tracing how order takes shape though negotiation, improvisation, co‐production and translation not only highlights how informality constitutes a modus operandi in the everyday workings of the state in all three cases, but also provides a way to talk across these cases, i.e. to bring them together in one frame of analysis and overcome their presumed incommensurability.     

It could have been me: Proximity motivates disaster giving

Effects of physical proximity of potential donors to a disaster location were studied. Physical proximity increased counterfactual thoughts, that is, thoughts that the donors themselves might have suffered from the event if the circumstances had been a bit different. Counterfactuals, in turn, increased reported willingness to help the victims of the disaster. The same effects were found for hypothetical proximity, in the form of a desire to visit the impacted location before the disaster occurred. The pattern was consistent across five correlational and experimental studies, which focused on a range of real‐life and fictitious disasters. The findings are important because they can explain why people and governments often dwell on relatively minor problems at home rather than thousands of people suffering and dying overseas. The findings also suggest an easy and cost‐effective way of boosting donations to disaster victims.     

Barrier-free outdoor environments: Older peoples’ perceptions before and after implementation of legislative directives

An increased focus on international and national levels of society to meet the transportation needs of older people and people with disabilities is realized through legislation, directives and guidelines on accessibility. This paper examines effects of removing physical barriers according to current Swedish governmental accessibility directives on older peoples’ perceptions of outdoor environments (usability) and on their mobility and perceived safety as pedestrians. This paper also focuses on municipal planners’ views on the implementation of improved accessibility. A before–after study, using both qualitative and quantitative methods, is conducted. The results from the questionnaires show that older peoples’ overall satisfaction with the outdoor environment has increased after implementation; however no differences are found if physical barriers specifically are considered. Older peoples’ mobility is also unchanged; nevertheless, fewer respondents are stating difficulties in walking due to barriers in the outdoor environments as reason to avoid outdoor mobility. Problems do remain after implementation, for example concerning safety/security-related issues and inaccessible entrances and indoor environments.     

We’re all connected: The power of the social media ecosystem

Consumers are adopting increasingly active roles in co-creating marketing content with companies and their respective brands. In turn, companies and organizations are looking to online social marketing programs and campaigns in an effort to reach consumers where they ‘live’ online. However, the challenge facing many companies is that although they recognize the need to be active in social media, they do not truly understand how to do it effectively, what performance indicators they should be measuring, and how they should measure them. Further, as companies develop social media strategies, platforms such as YouTube, Facebook, and Twitter are too often treated as stand-alone elements rather than part of an integrated system. This article offers a systematic way of understanding and conceptualizing online social media, as an ecosystem of related elements involving both digital and traditional media. We highlight a best-practice case study of an organization's successful efforts to leverage social media in reaching an important audience of young consumers. Then, we conclude with several insights and lessons related to the strategic integration of social media into a firm's marketing communications strategy.     

The impact of IFRS adoption on the value relevance of book value and earnings

In this study, we investigate the impact of IFRS adoption in Europe and Australia on the relevance of book value and earnings for equity valuation. Using a sample of 3488 firms that initially adopted International Financial Reporting Standards (IFRS) in 2005, we are able to compare the figures originally reported for the 2004 fiscal years to the IFRS figures that were provided in 2005 as the 2004 IFRS comparative figures. As part of the inquiry, we introduce a cross-product term, equal to the product of EPS and BVPS, into the traditional linear pricing models. The estimated coefficient on the cross-product term is statistically significant and negative, as theory suggests in the presence of important nonlinearities. Further, there is increased non-linearity in the data subsequent to IFRS adoption, with the increase being most pronounced for firms in Common Law countries. With non-linear effects controlled for, there is no observed change in price relevance for firms in either Code Law or Common Law countries, contradicting the results from the linear pricing models. The results also suggest that the distribution of measurement errors becomes more similar across Code Law and Common Law countries after the adoption of IFRS, removing one difference between these groups. Thus, IFRS enhances comparability, an inference that would not be possible had we confined the analysis only to linear pricing models.     

Headless: The Role of Gender and Self‐Referencing in Consumer Response to Cropped Pictures of Decorative Models

Product pictures with “headless” decorative models, whose heads have been cropped out of the pictures, are often used in online retailing. This article reports findings from three experiments comparing attitudes for clothing displayed in pictures with cropped and uncropped male and female models, focusing on the moderating effects of consumer and model gender and the mediating effects of product self‐referencing. Results indicate that the effects on product attitudes are moderated by the gender of both models and consumers and mediated by self‐referencing. Pictures with uncropped male models result in more positive product attitudes, irrespective of consumer gender. For product pictures with female models, male consumer attitudes are also more positive for products displayed with uncropped models. In fact, attitudes are only more positive for clothing shown with cropped, “headless” models when both models and consumers are female. Implications of the findings for research and practitioners are discussed.     

A new model of how celebrity endorsements work: attitude toward the endorsement as a mediator of celebrity source and endorsement effects

This research introduces attitude towards the endorsement as a mediating variable in the relationships between celebrity source and endorsement factors and brand attitude. It also includes perceived celebrity motive, a variable rarely studied in the previous literature, as an endorsement factor. In a survey study, respondents evaluated four celebrity endorsement campaigns. Mediation analyses show that attitude towards the endorsement mediates the effects of three variables on brand attitude; these variables are celebrity expertise, celebrity–brand fit, and perceived celebrity motive. Moreover, results show that if consumers perceive that the celebrity was motivated to do the endorsement not only by money but also by product quality, this has a significant positive effect on attitude towards the brand.     

PERIODICAL USEFULNESS: THE U.S. LOGISTICS EDUCATOR PERSPECTIVE

Traditional methodologies for evaluating periodicals focus on the quality of research‐oriented, peer refereed journals. This research broadens the evaluation process to include practitioner publications and an assessment of periodical usefulness across three educational activities. More than 100 U.S. logistics educators identified and evaluated periodicals germane to the logistics discipline. The Journal of Business Logistics, Harvard Business Review, and Supply Chain Management Review achieved the highest usefulness scores based on an analysis of the survey responses.
