International migration: facts,figures, policies

Recent trends in international migration in OECD member countries are summarized using data from the SOPEMI system, under which OECD countries report annually on international migration affecting them. The synopsis includes a review of recent changes in migration policies, as well as a summary of the impact of immigration on employment and demographic trends.     

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.     

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.

BUSINESS IMPROVEMENT DISTRICTS: PAST, PRESENT, FUTURE

The article covers the history of Business Improvement Districts (BIDs) in the USA and UK and some of the lessons learnt in the UK after the first year of operation. The authors then consider economic issues raised by the initiative and why BIDs will be the best option for some urban centres.     

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.
