Empirical regularity in academic research productivity patterns in marketing

In any academic discipline, published articles in their respective journals represent “production units” of scientific knowledge, and bibliometric distributions reflect the patterns in this productivity across authors or “producers”. We use a comprehensive data set from 11 leading marketing journals to examine whether there is any empirical regularity in the patterns of research productivity in the marketing literature. Our results present strong evidence that there is indeed a distinct empirical regularity. It is the so-called generalized Lotka's Law of patterns in scientific productivity: the number of authors publishing n papers is approximately 1/n^c of those publishing one paper. We find the empirically estimated value of the exponent c to be 2.05 for the overall bibliometric data across the leading marketing journals. For individual journals, the estimated values of c range from 2.15 to 2.83, with lower values indicating higher authorship concentration levels. We also find that variations in authorship concentration levels across journals and over time are driven by a journal's maturity, its topical focus, its attractiveness as a publication outlet, the characteristics of its review process, and the extent of author collaboration present in the journal. We discuss the general implications of our findings.     

A note on disease burden and pharmaceutical R&D

We examine the relationship between research and development (R&D) expenditures and the expected impact of diseases in a simple theoretical framework that allows for intellectual property rights (IPR) protection to be strong or weak. In our theoretical model, an agent forms an expectation of the impact of a disease using a publicly available statistic on the (population level) disease burden, such as disability-adjusted life year. We show that a profit-maximising firm will exert relatively more R&D effort on diseases with intermediate expected impacts. We also discuss how a weak IPR regime alters the pattern of R&D investment.     

Beating the recession blues: Exploring the link between family ownership,strategic marketing behavior and firm performance during recessions

This study explores whether family firms exhibit unique marketing behavior and whether their unique behavior in turn helps them outperform non-family firms during periods of economic contraction. Findings based on a sample of 275 large publicly listed U.S. firms reveal that family firms outperform non-family firms during recessions. This superior performance is partially driven by family firms' proactive marketing behavior and their relatively strong emphasis on corporate social responsibility (CSR). During recessions, while non-family firms tend to decrease their advertising intensities and rates of new product introduction (NPI), family firms are likely to maintain relatively high levels of advertising intensity and rates of NPI. Unlike non-family firms, family firms are also likely to maintain high levels of corporate social performance (CSP) during recessions. These results underscore the benefits of proactive marketing behavior and a continued emphasis on CSR during economic downturns. The authors also add to the scant family-firm literature, demonstrating the family firm to be an effective organizational form.     

Exchange Rate Exposure of Exporting and Importing Firms

Although economic theory and conventional wisdom suggest that U.S. multinationals and export-oriented firms are adversely affected by a strengthening dollar and benefit from a depreciating dollar, the research to date provides little evidence of any relationship between FX changes and the stock prices of such firms. The authors propose a "dual-effect" hypothesis that distinguishes between (1) the direct competitive effect of currency induced changes on the effective price to consumers of the firm's products and (2) an indirect effect stemming from the generally positive correlations between currency levels and the strength of the domestic economy. Thus, for example, while a strong dollar hurts exports, it also tends to be associated with a strong domestic market and higher domestic sales. For this reason, the net effect on exporters of a stronger dollar could be close to zero. On the other hand, a weak dollar tends to have a "doubly" negative effect on importers because of higher import prices and the associated weakness of the local economy. For this reason, importers—in contrast to exporters—are likely to have significant exposures to currency fluctuations.
Consistent with these arguments, the authors' econometric analysis reveals a significantly positive currency exposure for importers and insignificant exposure for exporters, based on correlations between stock returns and currency changes. But when the benchmark is non-exporting domestic firms instead of a marketwide index (which contains exporters), a stronger currency is associated with a significantly negative effect on exporters.

Disruptiveness of innovations: measurement and an assessment of reliability and validity

Strategic management scholars have long explored the broad topic of innovation, a cornerstone in creating competitive advantage. Any attempt at theory construction in this area must encompass reliable and valid measures for key innovation characteristics. Yet, with respect to an important construct, i.e., disruptiveness of innovations, there has been relatively little academic research. Without formalizing the disruptiveness concept with a reliable and valid measure, it is difficult to conduct rigorous research to uncover the causes of the innovator's dilemma and identify mechanisms to help incumbents develop such innovations. In this paper, we develop a scale for the disruptiveness of innovations. We collected data from senior executives (vice president or general manager level) at 199 strategic business units (SBUs) in 38 Fortune 500 corporations and performed a series of analyses to establish the reliability and validity of the disruptiveness scale. The reliability measures, exploratory factor analysis, confirmatory factor analysis, and subsequent statistical tests strongly support our measure. Further, we also present nomological validity of the disruptiveness construct, thus establishing its predictive validity. Thus, this paper distinguishes the disruptiveness concept from other established innovation constructs, such as radicalness and competency destroying. Finally, we discuss the significance of our results and how this study might be useful to other researchers. Copyright © 2006 John Wiley & Sons, Ltd.     

An Exploration of the Role Duality Experienced by HR Professionals as Both Implementers and Recipients of HR Practices: Evidence from the Indian Railways

This study provides an innovative perspective on empirically assessing HR by focusing on the duality of HR professionals’ experiences as both implementers and recipients or internal customers of HR practices given that they are also employees of the organization. We hypothesize that HR professionals experience HR practices more favorably from an implementer perspective as compared to an internal customer perspective. These differences in experiences are likely to be influenced by HR professionals’ hierarchical position in the HR department. Our analyses of 1,271 HR professionals employed by Indian Railways revealed a number of differences between the two types of experience. Some practices (recruitment and selection, training, and employee welfare) were viewed more negatively from the implementer perspective, whereas others (compensation, benefits, and employment relations) were rated more negatively from the internal customer perspective. Those holding more senior HR positions reported more positive experiences of training and employment relations from an internal customer perspective. Overall our contributions draw on the attribution theory and concepts of intraorganizational power and voice, and have implications concerning the effectiveness of HR practices. © 2015 Wiley Periodicals, Inc.     

Kaldorian Disaggregation,Temporary Migration and Domestic Welfare

We build a model with two agents: domestic residents and temporary immigrants. The model incorporates Kaldorian disaggregation, with the two groups consuming different goods produced in the economy. It is established that, under certain conditions, an increase in immigrant labor lowers the welfare of the domestic residents. This runs against conventional wisdom that temporary immigration enhances the welfare of domestic residents.     

Skills in South Africa: The journey towards credible planning

ABSTRACT

Since 1994 the state has instituted active labour market policies to redress the apartheid skills legacy. The skills planning challenge continues to be how to coordinate efforts for the provision of the right skills to support inclusive economic growth, ensuring an alignment is achieved between what is required in the labour market and the supply from the education and training system. This article traces the South African journey of skills planning from late apartheid until the current time period in 2014 through a historical analysis of the political economy. The analysis reflects on the relationship between state formation in South Africa and the role of the state in directing skills development, and in the more recent period how skills planning responds to both the demands of the economy and ameliorating the historical legacies of education and skills exclusion.     

Communication in games of incomplete information: Two players

We study the effect of communication in two-person games of incomplete information. We show that for any two-player game of incomplete information, any rational mediated communication mechanism outcome (satisfying a Nash domination condition) can be implemented as the perfect Bayesian equilibrium of a cheap-communication extension of the original game.
