Researchers recommend a reorganization of the medical profession into larger groups with a multispecialty mix. We analyze whether there is evidence for the superiority of these models and if this organizational transformation is underway.

We summarize the evidence on scale and scope economies in physician group practice, and then review the trends in physician group size and specialty mix to conduct survivorship tests of the most efficient models.

The distribution of physician groups exhibits two interesting tails. In the lower tail, a large percentage of physicians continue to practice in small, physician-owned practices. In the upper tail, there is a small but rapidly growing percentage of large groups that have been organized primarily by non-physician owners.

While our analysis includes no original data, it does collate all known surveys of physician practice characteristics and group practice formation to provide a consistent picture of physician organization.

Our review suggests that scale and scope economies in physician practice are limited. This may explain why most physicians have retained their small practices.

Larger, multispecialty groups have been primarily organized by non-physician owners in vertically integrated arrangements. There is little evidence supporting the efficiencies of such models and some concern they may pose anticompetitive threats.

This is the first comprehensive review of the scale and scope economies of physician practice in nearly two decades. The research results do not appear to have changed much; nor has much changed in physician practice organization.

The growing displacement of theory and other forms of wide-ranging knowledge of social phenomena by empirical research methods in economics is widely noted by economists and historians of economic knowledge. Less attention has been devoted, however, to understand the materialization of such changes in the scientific practices. This article studies the recent transformations in the epistemological practices at CEDE, a research center in Colombia. I use a machine learning technique called Topic Modeling, interviews to CEDE researchers, and exegesis of papers to characterize a shift in the production of knowledge in microeconometrics at CEDE during the years 2000 and 2018. I explain this shift by characterizing two sets of epistemological practices that implies a recent tendency to disdain research that cannot make a “strong” causal inference.

This chapter proposes semiparametric estimation of the relationship between growth rate of GDP per capita, growth rates of physical and human capital, labor as well as other covariates and common trends for a panel of 23 OECD countries observed over the period 1971–2015. The observed differentiated behaviors by country reveal strong heterogeneity. This is the motivation behind using a mixed fixed- and random coefficients model to estimate this relationship. In particular, this chapter uses a semiparametric specification with random intercepts and slopes coefficients. Motivated by Lee and Wand (2016), the authors estimate a mean field variational Bayes semiparametric model with random coefficients for this panel of countries. Results reveal nonparametric specifications for the common trends. The use of this flexible methodology may enrich the empirical growth literature underlining a large diversity of responses across variables and countries.

The relationship between work and family has long been the subject of lively debate in the political, public, and academic arena. Employers in the hospitality industry should carefully consider the work–family balance of their employees because maintaining a good balance will result in lower costs, lower sick rates, and lower staff turnover. The term “balance” refers to the way in which work interferes with life at home and how home life interferes with work. It includes both the positive and negative effects that work has on the family domain and vice versa. As research on the psychological contract approach to the employment relationship is scarce with regard to work–family interference, it became the subject of this study. The results demonstrate that psychological contract measures, in particular time commitment, can explain work–family conflict, while job content can explain work–family enrichment. In addition, the study revealed that with the appearance of gender as a moderator, different additional factors may play a role in work–family enrichment and work–family conflict. Furthermore, it revealed that family structure is not a predictor for work–family interference. This paper discusses managerial implications and offers recommendations for further research.

To reexamine the Weber Thesis pertaining to the relationship between ascetic Protestantism – especially Calvinism – and modern capitalism, as between an economic “spirit” and an economic “structure,” in which the first is assumed to be the explanatory factor and the second the dependent variable.

The chapter provides an attempt to combine theoretical-empirical and comparative-historical approaches to integrate theory with evidence supplied by societal comparisons and historically specific cases.

The chapter identifies the general sociological core of the Weber Thesis as a classic endeavor in economic sociology (and thus substantive sociological theory) and separates it from its particular historical dimension in the form of an empirical generalization from history. I argue that such a distinction helps to better understand the puzzling double “fate” of the Weber Thesis in social science, its status of a model in economic sociology and substantive sociological theory, on the one hand, and its frequent rejection in history and historical economics, on the other. The sociological core of the Thesis, postulating that religion, ideology, and culture generally deeply impact economy, has proved to be more valid, enduring, and even paradigmatic, as in economic sociology, than its historical component establishing a special causal linkage between Calvinism and other types of ascetic Protestantism and the “spirit” and “structure” of modern capitalism in Western society at a specific point in history.

In addition to the two cases deviating from the Weber Thesis considered here, it is necessary to investigate and identify the validity of the Thesis with regard to concrete historical and empirical instances.

The chapter provides the first effort to systematically analyze and distinguish between the sociological core and the historical components of the Weber Thesis as distinct yet intertwined components.

The body of literature in the field now commonly known as the “quality of working life” (QWL) has grown steadily over a period in which the industrialised nations have increasingly come to question the role and status of human beings in the modern technological environment. In recent years concern with the nature of work, its impact upon people, and their attitudes towards it, seem to have sharpened. Investigation of, and experimentation with, the qualitative aspects of working life—its ability to confer self‐fulfilment directly, for example, as opposed to being a means of acquiring goods—has gained momentum under the influence of a unique set of economic, social, political and technological factors. The outpouring of books, reports and articles from a wide variety of sources has, not surprisingly, grown apace.
