Polarization: Concepts,Measurement, Estimation

We develop the measurement theory of polarization for the case in which income distributions can be described using density functions. The main theorem uniquely characterizes a class of polarization measures that fits into what we call the “identity‐alienation” framework, and simultanously satisfies a set of axioms. Second, we provide sample estimators of population polarization indices that can be used to compare polarization across time or entities. Distribution‐free statistical inference results are also used in order to ensure that the orderings of polarization across entities are not simply due to sampling noise. An illustration of the use of these tools using data from 21 countries shows that polarization and inequality orderings can often differ in practice.     

The `Game' of Leadership: Exercise, Games, Sports, and Leadership

The relationship between leadership and sports was analyzed. Peer influence was most important, with that of teachers and parents seeming to have a second-order effect as perceived through peers. Each gender benefitted more in leadership when mentored by their own gender, especially so for women. In work settings, men reported more leadership learning and encouragement than did women. Women experienced more frustration in participating in games and sports in school, the encouragement and continued mentoring being insufficient. Harragan's 1977 thesis that the corporate world and the playing field of sports and high-level policy-making have a male schema was borne out.     

Servitization of business updated: Now,new, next

Coined in 1988, “servitization” has become the go-to concept for enhancing corporate competitiveness through value-added services. Over the years, the notion of value-added services to create a competitive edge, enhanced customer relationships, and market power has changed, facilitated by ever advancing technology. The authors look at this progression, spanning from the 1970s to the 2020s and into the future, with examples in both a B2B and B2C context. This is intended to assist both academics and practitioners in positioning themselves and taking steps to advance their research, thinking, and strategies.     

Three Critical Characteristics of Leadership: Character,Stewardship, Experience

There is no one definition of leadership. The leadership equation is never set or fixed. Time, place, specific problems, the particular parties involved all play a role in the leadership equation. Nor is there one specific list of attributes, virtues, or skills that all leaders must and do possess. Nonetheless, we argue that at its core, all forms of ethical leadership are based on three elemental ingredients: character, stewardship, and experience.     

Trade credit: the interaction of financing,marketing, operations,and risk behavior

This paper builds an inter-organizational Stackelberg game model of trade credit. The incentive-compatible decision on credit term is made endogenously and in coordination to ensure Pareto optimality for both the supplier and the retailer. Our model factors in financing, marketing, operations, default risk, and risk attitude coherently, treating trade credit as their intersectional nexus. We introduce the uncertainty due to the possible default of the retailer on the accounts payable into our model. The in-kind nature of trade credit is in line with the two-stage lottery method employed in this paper to capture the consequences of default on trade credit effectively. We find that financing capacity encourages the supplier to extend the credit term: a larger market demand rate prompts the supplier to extend a longer credit term, but a higher holding cost for the retailer shortens the length of the credit term received. More risk-averse suppliers tend to grant shorter term, but the impact of risk attitude is insignificant. Empirically, we find evidence supporting our main theoretical predictions by employing a panel sample of manufacturing companies covering 1998–2007 from the COMPUSTAT database.     

The future of HRD research: Strengths,weaknesses, opportunities,threats and actions

This article clarifies the boundaries of human resource development (HRD) with respect to other concepts frequently used and misused in HRD literature. Through a proposition, a set of criteria for human resources is presented. A cross-culture literature comparison of the criteria demonstrates the consistency of the connotation in two contrasting cultures. This study has important implications for HRD research, practice and continued theory development effort. It relates to the identity and distinctiveness of HRD discipline, as well as the domain of HRD research and practice.     

Producing Synergy: Innovation,IT, and Productivity

Bringing innovations to market is critical to industrial progress and economic growth. We explore the potential for information technology (IT) to enable innovations, and thus improve productivity. We hypothesize that a knowledge stock of process‐oriented research and development (R&D) increases total factor productivity growth by leveraging traditional forms of capital and labor, and further enhances the ability of IT capital to increase productivity. We estimate these relationships using two broad panels of U.S. industries covering the periods 1987–1998 and 1998–2005. The results indicate qualified support for a synergistic effect of R&D and IT investment in both periods.     

Romancing leadership: Past, present, and future

This paper presents a review of the romance of leadership and the social construction of leadership theory 25 years after it was originally introduced. We trace the development of this theoretical approach from the original formulation of the romance of leadership (RoL) theory as attributional bias through its emergence as a radical, unconventional approach that views leadership as a sensemaking activity that is primarily ‘in the eye of the beholder.’ We subsequently review research published in management and organizational psychology journals, book chapters and special issues of journals from 1985 to 2010. Three overall themes emerged from this review: 1) biases in (mis)attributions of leadership, including attributions for organizational success and failure; 2) follower-centered approaches, including the role of follower characteristics, perceptions, and motivations in interpreting leadership ratings; and 3) the social construction of leadership, including interfollower and social contagion processes, the role of crisis and uncertainty, and constructions and deconstructions of leadership and CEO celebrity in the media. Within each of these themes, we examine developments and summarize key findings. Our review concludes with recommendations for future theoretical and empirical work in this area.     

Labour Market Policies: Welfare,Incomes, Employment

The — in some ways innovative — objective of this paper is the study of the dynamics of the disequilibria provoked by the emergence of involuntary unemployment in the labour market, and the role of the economic policy authorities (through welfare, incomes and employment policies), with the aim of discovering if there is an explicit or implicit consistency between the role of these authorities, their actions and the pursuit of maximum employment (or elimination of the disequilibria). We seek to show, in other words, whether the actions of the government authorities conform to their accepted meaning (the aim of reducing the disequilibria) or whether, on the contrary, it may not be possible to put forward a different interpretation, if sociopolitical variables are introduced into the analysis, thus placing in the foreground different and alternative objecties such as “conflict control” and/or the reaching of a consensus between the different social partners. The paper therefore begins by analysing separately the historical-theoretical characteristics of the individual policies considered — welfare, incomes and employment — in their evolution (with particular reference to the last two decades), and then attempts an interpretative key in synthesis, by resorting to a specific model derived from the theories of disequilibria.
