An empirical analysis of ‘acting white’

Using a newly available data set, which allows one to construct a novel measure of a student's social status, we demonstrate that there are potentially important racial differences in the relationship between social status and academic achievement. The effect is concentrated among students with a grade point average (GPA) of 3.5 or higher and more pronounced in schools with more interracial contact. Earlier studies showing a positive relationship between popularity and academic achievement for blacks are sensitive to the inclusion of more continuous achievement measures. We argue that the data are most consistent with a model of ‘acting white’ in which investments in education are taken as a signal of one's opportunity costs of peer-group loyalty, though imprecise estimates make definitive conclusions difficult.     

DO WE REALLY NEED CENTRAL BANKS?

An analysis of economic theory and economic history suggests that central banks, with a monopoly of money-issuing services, are not necessary. The often-levelled arguments against private banks issuing money in competition with each other and with central banks do not stand up to close scrutiny.     

The link between board composition and board objectives: an empirical analysis on Flemish non‐profit schools

Flemish non‐profit schools have no legally imposed composition rules with respect to their board of directors. Hence, large variation exists in their size and composition. We argue that these differences in board composition can result in different policies followed by the board. To empirically test this hypothesis we question the board's chairpersons of Flemish non‐profit schools about the objectives set forward by the board. Ordered probit regressions on the importance attached to different educational objectives provide support for our hypothesis and thus alert policy makers to account for the linkages between objectives and board characteristics when formulating legislation with respect to school board composition.

Research Networks And Organisational Mobility In An Emerging Technological Field: The Case Of Plant Biotechnology

This paper builds on social network theory to understand technological development. Based on the empirical evidence of 367 research organisations in plant biotechnology over a nineteen-year period, we demonstrate how a structural analysis of the research network within the technological community is used to identify four collaboration-based strategic groups of research organisations. The emergence of these groups can be linked to technological breakthroughs in the field. Analyses of the four clusters point to the influence of research collaborations on stratification within an evolving technological domain. Finally, as archival data sources are used to detect incidences of collaborative research and to trace the evolution of R&D networks in an emerging field, we conclude with a discussion of the potential contribution of bibliometric data to understand the development of new technologies in their early, pre-commercial phases.     

HR practices in US and Australian family wineries: cultural contrasts and performance impact

Research on human resource practices within family businesses is limited, particularly in the wine industry. In this comparative study, 57 US and 37 Australian small and mid-sized family wineries responded to a comprehensive survey of their human resource systems. In addition to contrasting HR practices between family wineries in different countries, this study analyzed the impact of these activities on company sales and profitability. Results were consistent with the hypotheses: US firms were more likely to formalize HR practices than their Australian counterparts, Australian wineries emphasize worker training whereas US wineries focus on hiring qualified employees and both groups connected formalized HR practices to effectiveness and profitability. Finally, the US wineries reported higher profitability than Australian wineries. Implications of the results are discussed and directions for future research are suggested.     

Mediated contracts and mechanism design

The framework of incentive compatible finite direct coordination mechanisms in the sense of Myerson (1982) [5] is isomorphic to a framework of incentive compatible stochastic mediated contracts in the sense of Rahman and Obara (2010) [11] and Rahman (2009) [10]. The equivalence follows because the framework of Myerson (1982) [5] allows for a correlation between recommendations and transfers. The literature has hitherto not recognized the importance of this correlation for the structure of optimal contracts and for extending the revelation principle to address agency (moral hazard) problems.     

Eine Replik zu J. Faik und T. Köhler-Rama

The Death of Advertising

Abstract

Mass media advertising as we know it today is on its deathbed, and its prognosis is poor. Advertising agencies are restructuring to accommodate a harsher advertising climate, agency income is flat, agency employees are being laid off, direct marketing is stealing business from traditional advertising, and the growth of sales promotion and integrated marketing communications both come at the expense of traditional advertising. The reason for advertising's impending demise is the advent of new technologies that have resulted in the fragmentation of media and markets, and the empowerment of consumers. In the place of traditional mass media advertising, a new communications environment is developing around an evolving network of new media, which is high capacity, interactive and multimedia. The result is a new era of producer-consumer interaction. Because of the speed of technological innovation, the new media advertising paradigm that results will attain prominence faster than did mass media advertising. The new paradigm of 21st Century Marketing and advertising will be dominant by 2010 and should last well into the middle of the century. If they hope to survive, university advertising departments will have about ten years to 1) think of themselves much more broadly, and 2) transform themselves into departments specializing in information transfer in the new media environment.
