A recurrent problem in the analysis of behavioral dynamics, given a simultaneously evolving social network, is the difficulty of separating the effects of partner selection from the effects of social influence. Because misattribution of selection effects to social influence, or vice versa, suggests wrong conclusions about the social mechanisms underlying the observed dynamics, special diligence in data analysis is advisable. While a dependable and validmethod would benefit several research areas, according to the best of our knowledge, it has been lacking in the extant literature. In this paper, we present a recently developed family of statistical models that enables researchers to separate the two effects in a statistically adequate manner. To illustrate our method, we investigate the roles of homophile selection and peer influence mechanisms in the joint dynamics of friendship formation and substance use among adolescents. Making use of a three-wave panel measured in the years 1995–1997 at a school in ...

Dynamic networks and behavior: separating selection from influence

This paper discusses some developments in the theory of the organizational capabilities of the business enterprise. Antecedents are recognized, and some promising new developments and areas for future research are identified. The role of managers in the economic system is highlighted and discussed within the context of economic and organizational research. Suggestions for future developments of dynamic capability research involve employment of evolutionary and behavioral theories.

Dynamic Capabilities and the Role of Managers in Business Strategy and Economic Performance

By reducing the fear of a hostile takeover, business combination (BC) laws weaken corporate governance and create more opportunity for managerial slack. Using the passage of BC laws as a source of variation in corporate governance, we examine if these laws have a different effect on firms in competitive and non-competitive industries. We find that while firms in non-competitive industries experience a significant drop in performance after the laws' passage, firms in competitive industries experience virtually no effect. While consistent with the general notion that competition mitigates managerial agency problems, our results are, in particular, supportive of the (stronger) Alchian-Friedman-Stigler hypothesis that competitive industries leave no room for managerial slack. When we examine which agency problem competition mitigates, we find evidence in support of a "quiet-life" hypothesis. While capital expenditures are unaffected by the passage of the BC laws, input costs, wages, and overhead costs all increase, and only so in non-competitive industries. We also conduct event studies around the dates of the first newspaper reports about the BC laws. We find that while firms in non-competitive industries experience a significant stock price decline, firms in competitive industries experience a small and insignificant price impact.

How to perform and report an impactful analysis using partial least squares: Guidelines for confirmatory and explanatory IS research

Milton Friedman's 1953 essay 'The methodology of positive economics' remains the most cited, influential, and controversial piece of methodological writing in twentieth-century economics. Since its appearance, the essay has shaped the image of economics as a scientific discipline, both within and outside of the academy. At the same time, there has been an ongoing controversy over the proper interpretation and normative evaluation of the essay. Perceptions have been sharply divided, with some viewing economics as a scientific success thanks to its adherence to Friedman's principles, others taking it as a failure for the same reason. In this book, a team of world-renowned experts in the methodology of economics cast new light on Friedman's methodological arguments and practices from a variety of perspectives. It provides the 21st century reader with an invaluable assessment of the impact and contemporary significance of Friedman's seminal work.

The Methodology of Positive Economics

There is an embarrassing polarization of opinions about the status of economics as an academic discipline, as reflected in epithets such as the Dismal Science and the Queen of the Social Sciences. This collection brings together some of the leading figures in the methodology and philosophy of economics to provide a thoughtful and balanced overview of the current state of debate about the nature and limits of economic knowledge. Authors with partly rival and partly complementary perspectives examine how abstract models work and how they might connect with the real world, they look at the special nature of the facts about the economy, and they direct attention towards the academic institutions themselves and how they shape economic research. These issues are thus analysed from the point of view of methodology, semantics, ontology, rhetoric, sociology, and economics of science.
