This chapter argues that the Marxian theory of exploitation underlies the concepts of surplus and deficit industries that appear in Sraffa’s (1960) Production of Commodities by Means of Commodities. This is seen from archival research of the unpublished papers of Piero Sraffa housed at the Wren Library, Trinity College, University of Cambridge. There it is shown that the origin of these concepts lies in the Marxian theory of exploitation that Sraffa developed regarding the notion of the ‘pool of profits’ the Italian economist utilized over a 14-year period from 1942 to 1956. The chapter engages in an extensive textual study of the archival evidence and then presents a simple analytical model of these relations.

This essay explores certain aspects of single product industry basic systems of the type Sraffa develops in Part I of Production of Commodities by Means of Commodities. It focusses on triangular trade as the simplest expression of the more general n-commodity case. Two elements of the framework are explored: (i) the relation of exchange between all commodities, conceived as the configuration of exchange which is applicable to the subsistence and surplus models, and (ii) the value/price expressions of labour time, applicable to the surplus model only, which posits the productivity of, remuneration to and extraction from living labour added to the system. This analysis complements and extends the Marxian reading of Sraffa’s notions of surplus and deficit industries first explored in Carter (2014b). The methodology of ‘given quantities’ in expositing the relations developed is adopted in this essay as it corresponds to the same method employed by Sraffa. This allows readers to easily move from the present essay to Sraffa’s book and importantly his archival notes which are now for all interested parties available as colour digital images on the Wren Library website.

Sraffian's concept or metaphor of a “pool profits” is theoretically pointless and empirically irrelevant. The appropriate calculation is the variation of the equilibrium price vector along the factor price frontier.

Professor Solow’s original comment from 2007 is addressed seven years later. Here the foundational character of Sraffa’s archival material is stressed and no longer is the search for what Sraffa “really said” or much more nefariously what he “really meant” (especially as regards the relation to Marx) the endeavour pursued. This means rendering unto Sraffa what is his and using the foundations he provides from archival material to re-conceive Marxian income distribution theory and policy as a “positive” aspect of economic science.

The explicit assumption in most literature on educational and skill mismatches is that these mismatches are inherently costly for workers. However, the results in the literature on the effects of underqualification or underskilling on wages and job satisfaction only partly support this hypothesis. Rather than assuming that both skill surpluses and skill deficits are inherently costly for workers, we interpret these mixed findings by taking a learning perspective on skill mismatches. Following the theory of Vygotski on the so-called “zone of proximal development,” we expect that workers who start their job with a small skill deficit, show more skill growth than workers who start in a matching job or workers with a more severe skill deficit. We test this hypothesis using the Cedefop European skills and jobs survey (ESJS) and the results confirm these expectations. Workers learn more from job tasks that are more demanding than if they would work in a job that perfectly matches their initial skill level and this skill growth is largest for those who start with a small skill deficit. The learning opportunities are worst when workers start in a job for which they have a skill surplus. This is reflected in the type of learning activities that workers take up. Workers with a small skill deficit are more often engaged in informal learning activities. Finally, workers who started with a small skill deficit are no less satisfied with their job than workers who started in a well-matched job. We conclude that a skill match is good for workers, but a small skill deficit is even better. This puts some responsibility on employers to keep job tasks and responsibilities at a challenging level for their employees.

This study aims to investigate the possibility of practicing cross-subsidisation of underwriting surplus among different takaful operators. It responds to the recent discussion paper published by Bank Negara Malaysia (BNM) on broader application of tàawun (mutual assistance), which seeks insights into cross-tàawun of underwriting surplus within takaful industry.

A qualitative, semi-structured interview is used to gather primary data, featuring 13 one-to-one interviews with selected Sharìah and operational experts in takaful. Open-ended questions are drafted according to BNM’s discussion paper to guide the interview. A content analysis method is used to delve into the topic based on scholarly papers, books and regulatory guidelines. A thematic analysis is applied to explore the qualitative data.

This study establishes the feasibility of cross-subsidisation of underwriting surplus in takaful. Given that participants are the rightful owners of the underwriting surplus, cross-tàawun is deemed permissible with participants’ consent. With the view that underwriting surplus belongs to the fund due to outright transfer of contributions by participants, the regulators have discretion to permit cross-tàawun. The authorities can make any decision if it serves the public interest. Furthermore, the study provides Sharìah and regulatory requirements to govern the practice of cross-tàawun in takaful. Respondents of the study advocate for policy reviews and regulatory adjustments to facilitate cross-subsidisation of takaful surplus.

This study significantly contributes to the existing body of knowledge in Islamic insurance studies. It offers valuable insights for the regulators to formulate the required policies and guides takaful operators to develop products accordingly. Moreover, the study supports Sharìah scholars in making informed decisions about cross-tàawun practices.

This study fills a critical gap in the existing literature by being the first to examine cross-subsidisation of underwriting surplus in takaful. The proposed cross-subsidisation of underwriting surplus will enhance sustainability of takaful funds and contribute to stability of takaful industry. As a foundation, this study encourages future research to explore other relevant aspects of cross-subsidisation of underwriting surplus in takaful operation.

The recent decline in funding levels of defined benefit pension plans (DBPs) has attracted the attention of regulators in Australia and other jurisdictions. In light of such scrutiny, this study provides timely empirical evidence of the economic and regulatory implications of the recent change in the financial position of DBPs sponsored by Australian listed companies. We identify that over the four‐year period from 2000 to 2003 the frequencies of both accrued benefits deficits and vested benefits deficits increased sharply after 2001. Coinciding with the increased incidence of deficits, the time lag in measuring accrued and vested benefits declined significantly. Controlling for firms taking contribution holidays, we find that the market prices vested benefits surpluses and deficits, and accrued benefits deficits, but not accrued benefits surpluses. This asymmetric treatment of firms’ superannuation funding positions is consistent with accounting conservatism theories and, as a consequence, has implications for recent adoption of IFRS accounting standards requiring Australian companies to recognise both accrued benefits surpluses and deficits.
