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 political crisis related to two main factors internal to the public revenue system, namely financial markets and the commercialisation of the state, and three related external factors, pertaining to the pandemic, popular discontent and inequality. The emphasis on financial markets since the mid-1990s expanded the commercialisation of the state while neglecting public accountability and government oversight. The efforts to shore up public finances through the tax system is increasingly undermined by the global tax architecture, enabling financial secrecy and illicit financial flows.

The pandemic revealed the significance of women’s work, paid as well as unpaid care work. The pandemic also exposed the limitations of a domestic economy, based on export-oriented development, over-reliant on tourism and remittances from migrant workers. Combining with the on-going dengue epidemic, the pandemic highlighted the urgency of climate adaptation. Meanwhile, the popular discontent conveyed an accumulation of grievances linked with cultural discrimination, political misrepresentation as well as economic maldistribution. The participation of new middle-class segments in the protests foregrounded new tendencies significant for strengthening the labour movement as well as working-class parties in their demands for redistribution, reframing democracy as well as citizenship.

This paper examines how medical practice, like all other productive activities, has been subject to the transformative elements of the forces and the relations of production involving class struggle and intra-class conflict. It will explore changes in the relations of production of medical practice which have been catalyzed by powerful productive forces. The current period of medical production involves the transformation of simple commodity production into a transitional stage of capitalist production with the seemingly unbounded growth of the medical productive forces. This development was precipitated by the intervention of capital as a whole, to restrict the drain on their variable capital through the placement of units of financial capital into the management of medical production, using the leverage of access to patients. In response, physicians have consolidated and centralized their practices to create enterprises with market power to limit the extraction of surplus by financial capital, and by their own employment of productive labor to extract surplus from hired physician labor and other clinical workers. Rationalization of the production of medical service commodities, and the sharing of surplus generated from exploitation of an expanded labor force by managed care financial capital and their capitalist partners owning medical enterprises, constitutes the contemporary relations of production. The contradictions of this mode of medical production and the potential for its reproduction will be analyzed.

“Economics is a Serious Subject.” Edwin Cannan.

Blockchain is often presented as a technological development; however, clearly it is not only that: the ‘Blockchain buzz’ exists in the context of current social and political developments. In this essay, we analyse blockchain technology and its social and political context from a perspective of Marxist economic theory. Since arguably the last great inflection point in society and technology was analysed by Marx in terms of labour and capital and since we seem to be experiencing a shift in the balance between these forces today, it makes sense to revisit the Marxist ideas and apply them to the current situation, to see how well they still apply and if necessary to update them for current events.

Industry 4.0 refers to an era in which human work, creative activities and professional knowledge are largely replaced by artificial intelligence (AI) and robots. Due to the current exponential rate of technological development and the infinite expansion and generalisation of technologies, it is not difficult to predict that these technologies will spread at exponential rates and will spur massive changes in the adopted production, management and governance mechanisms and in the future employment market. Especially, employment changes are inevitable with the rise in automation and the job scope and prospects are bound to vary widely. In this chapter, confrontation strategies for employment in Industry 4.0 are proposed. It is hoped that this study will be able to provide an accurate direction for future employment and will be able to contribute to the study of employment policies and Industry 4.0.

The objective of this chapter is twofold. It first explores the complementarities of Islamic investment with Socially Responsible Investment. Secondly, it examines the financial price, for investors, of being both shariah-compliant and socially responsible.

Using a value-weighted approach, we experiment the construction of a set of sharia-compliant stock portfolios with different Environmental, Social, and Governance (ESG) performance. We use the KLD ratings of 238 companies listed in U.S. stock market from 2007 to 2011. We measure and compare their performance using the model developed by Fama and French (1993) and extended by Carhart (1997).

The results indicate no adverse effect on returns due to the application of a double screening, Islamic and SRI, and show a substantially higher performance for positive governance screen during 2008–2011 periods. This outperformance cannot be explained by differences in investment style. Though, we observe significant outperformance for some ‘irresponsible’ portfolios involved in community and human rights controversies.

The study only focuses on U.S. market. Future works should extend the experimentation to other markets.

This study provides a venue for Islamic funds managers to consider SRI screening as fully in line with shariah-compliance requirements, while preserving the performance of their portfolios.

Potentially, the reconciliation of Islamic investment with positive SRI practices may foster the implementation of CSR policies by firms’ manager willing to attract Islamic investors.

With reference to the many studies emphasising the compatibility between CSR criteria and Islamic principles, this experimental study is the first to investigate the integration of a positive screening process designed to select companies based on their ESG performance in addition to a traditional shariah-compliant screening.
