Reciprocity,Multiplexity, and Exchange: Measures

We introduce measures and statistical tests for multiplexity and exchange that are modeled on similar ideas developed for reciprocity quite early in the history of social network research. As properties of a multi-relation network, multiplexity, and exchange have almost as ancient a history as reciprocity, but have not been as intensively investigated from a methodological perspective. Multiplexity refers to the extent to which two ties, for example, advice and friendship, coincide over population; that is, do respondents name the same people as friends as the persons they nominate as individuals from who they seek advice. Exchange refers to the extent to which a tie of one type directed from person i to person j is returned by a tie of another type from j to i. We conceive of the current paper as the first part of a two-part paper, wherein the second part explores specific theoretical models for multiplexity and exchange.     

HRM and culture: History,ritual, and myth

The concept of organizational culture is here applied to the practice of human resource management. Reasons for the current emphasis on culture as an organizational metaphor are suggested. Cultural indicators which have diagnostic value for human resource professionals include organizational usage of symbols, rituals, ideologies, language, stories, myths, relationship, and humor. Examples of these indicators of culture are drawn from a variety of HRM practices and functions to explore the implications of each indicator. Alternative strategies are presented for improving the management of organizational change through sensitivity to cultural impact and better utilization of existing cultural realities.     

Strategic entrepreneurship: Content,process, context,and outcomes

Strategic entrepreneurship (SE) is typically defined as organizationally consequential innovations within existing firms that involve the combination/integration of opportunity- and advantage-seeking behaviors. Focused on the transformation of organizations through innovation, SE is a construct that has generated much practitioner and scholarly interest in the preceding decades. Building upon the many contributions already observed on the topic, this paper aims to identify current limitations and central research issues of SE. Borrowing a framework from the change management literature, I diagnose current conceptualizations of SE and promote future research through careful consideration of the content, process, context, and relevant outcomes of SE. Examination of the extant literature would suggest there is still ample room for scholars to contribute to properly defining SE, understanding exactly how SE is manifest in organizations, uncovering relevant and opportune internal and external environments for SE to pervade, and identifying pertinent consequences and results from successful SE.     

Individual homelessness: Entries,exits, and policy

Homelessness is part of the lives of many people. But almost no one is homeless for all or most of his or her life. The median shelter homeless spell is well under a month, and even “chronic homelessness” officially entails spells of a year or so. I model homelessness as part of people’s lives in a dynamic stochastic framework in continuous time. I can explain many empirical regularities with a parsimonious model: for instance, why the last addresses of homeless people are concentrated in a few low-rent neighborhoods, why homeless entries are hard to predict, why recidivism is common and past homelessness is a good predictor of future homelessness, why some groups recidivate more often than others, why the hazard rate for shelter exit is single-peaked, why effective homelessness prevention programs do not alter the average length of homeless spells. I also examine policy. The optimal homelessness prevention program is Pigouvian and starkly simple. With an optimal prevention program in place, optimal shelter quality maximizes a simple and intuitive expression, and insurance programs always raise social welfare. Most of the previous economics literature about homelessness has been static, but most literature about homelessness outside economics has been dynamic. This paper tries to bring the two strands of literature closer together.

Re-innovation: The construct, measurement, and validation

There has been substantial research in the area of innovation, which is widely regarded as a powerful weapon to create competitive advantage. One important reason of the substantial research in innovation is the presence of valid and reliable measures of key innovation characteristics, such as radical, incremental, or disruptiveness innovation. Re-innovation, an extension of innovation, is renowned for its potential in creating competitive advantage with reduced cost and time implications. Unfortunately, very little research in re-innovation has been conducted, possibly because to date it still lacks a psychometrically valid measure. There is also a lack of research on convergent and discriminant validities of the re-innovation construct, resulting in the impossibility to discriminate re-innovation characteristics from radical or incremental innovation characteristics. The purpose of this paper is to develop a valid and reliable scale for measuring the construct of re-innovation. To test its reliability and discriminant and convergent validities, we used data collected from 294 general managers of SBUs in 89 electronics-related companies in Taiwan and performed a series of analyses. The reliability measures, exploratory factor analyses, confirmatory factor analyses, and convergent and discriminant validity tests strongly support our scale. In addition, nomological validity is demonstrated. Hence, this study distinguishes the re-innovation from radical and incremental innovation constructs. Finally, discussion, limitations, and future research are presented.

Productivity dispersion: facts,theory, and implications

This paper discusses the stylized facts, the theory, and the remaining problems of productivity dispersion, which is essentially related to the concept of equilibrium in the neoclassical theory. Empirical study of data relating to Japanese firms shows that they all obey the Pareto law, and also that the Pareto index decreases with the level of aggregation. In order to explain these two stylized facts we propose a theoretical framework built on the basic principle of statistical physics and on the concept of superstatistics, an approach that accommodates fluctuations of aggregate demand. We show that the allocation of production factors depends crucially on the level of aggregate demand, and that the higher the level of aggregate demand, the closer the economy is to the frontier of the production possibility set.     

Collective leadership: Practice,theory, and praxis

An act of leadership is always an act of practical theory. We lead because we hold visions of the world as it ought to be, because of the not yet, because of the potential that we see in ideas and people. Yet, there still exists a perceived binary between leadership theory (in the strong sense) and leadership practice, a binary that divides organizations, classrooms, and the differing bodies of leadership literature. In this Symposium, Duncan Waite and his colleagues discuss the barriers they have faced in bringing theory to the educational leadership classroom, as well as the promise they feel theory holds for more productive, equitable, and humane schooling organizations.     

Volatility, Efficiency, and Trading: Further Evidence

Along the lines of Amihud and Mendelson (1987a, 1989,1991), this study investigates the unique trading mechanism of the Korea Stock Exchange (KSE) and its intraday behavior of stock price volatility. The evidence from this study indicates that the introduction of an additional clearing procedure at the afternoon closing makes price discovery process more efficient than before from the viewpoint of stock price volatility. Hence, such trading mechanisms can be applied to emerging stock markets as well as developed stock markets. In addition, based on intraday analysis, stock price volatilities appear to occur mainly during the trading period, not during the lunch break or overnight period. Consequently, the results confirm the previous studies that information arrival and trading activities are the main sources of volatility.
