Objective – The South African health system has long been characterised by extreme inequalities in the allocation of financial and human resources. Voluntary private health insurance, delivered through medical schemes, accounts for some 60% of total expenditure but serves only the 14.8% of the population with higher incomes. A plan was articulated in 1994 to move to a National Health Insurance system with risk-adjusted payments to competing health funds, income cross-subsidies and mandatory membership for all those in employment, leading over time to universal coverage. This chapter describes the core institutional mechanism envisaged for a National Health Insurance system, the Risk Equalisation Fund (REF). A key issue that has emerged is the appropriate sequencing of the reforms and the impact on workers of possible trajectories is considered.

Methodology – The design and functioning of the REF is described and the impact on competing health insurance funds is illustrated. Using a reference family earning at different income levels, the impact on workers of various trajectories of reform is demonstrated.

Findings – Risk equalization is a critical institutional component in moving towards a system of social or national health insurance in competitive markets, but the sequence of its implementation needs to be carefully considered. The adverse impact of risk equalization on low-income workers in the absence of income cross-subsidies and mandatory membership is considerable.

Implications for policy – The South African experience of risk equalization is of interest as it attempts to introduce more solidarity into a small but highly competitive private insurance market. The methodology for considering the impact of reforms provides policy-makers and politicians with a clearer understanding of the consequences of reform.

Efficiency wage theory predicts that firms can induce worker effort by the carrot of high wages and/or the stick of monitoring worker performance. Another option available to firms is to tilt the remuneration package over time such that the lure of high future earnings acts as a deterrent to current shirking. On the assumption that firms strive for the optimal trade-off between these various instruments, we develop a two-period model of efficiency wages in which increased monitoring attenuates the gradient of the wage-tenure profile. Our empirical analysis, using two cross sections of matched employer-employee British data, provides robust support for this prediction.

On many occasions, organizational science research has been referred to as fragmented and disjointed, resulting in a literature that is, in the opinion of many, difficult to navigate and comprehend. One potential explanation is that scholars have failed to comprehend that organizations are complex and intricate systems. In order to move us past this morass, we recommend that researchers extend beyond traditional rational, mechanistic, and variable-centered approaches to research and integrate a more advantageous pattern-oriented approach within their research program. Pattern-oriented methods approximate real-life phenomena by adopting a holistic, integrative approach to research wherein individual- and organizational-systems are viewed as non-decomposable organized wholes. We argue that the pattern-oriented approach has the potential to overcome a number of breakdowns faced by alternate approaches, while offering a novel and more representative lens from which to view organizational- and HRM-related issues. The proposed incorporation of the pattern-oriented approach is framed within a review and evaluation of current approaches to organizational research and is supplemented with a discussion of methodological and theoretical implications as well as potential applications of the pattern-oriented approach.

This article investigates the links between universities’ opportunities to shape their research profiles, the changing state interest concerning these profiles, and the impact of profile building on research at university and field levels. While the authority of the Dutch state over research profiles of Dutch universities has increased, university management has considerable operational authority over the inclusion of new research fields and removal of existing research fields. Since all universities have begun to follow the same external signals prescribing applied research, research that has easy access to external funding, and research in fields prioritised by the state, a ‘quasi-market failure’ may emerge, as is demonstrated for evolutionary developmental biology and Bose-Einstein condensation.

This chapter investigates the dynamics of teenage girls' musical.ly productions in relation to microcelebrity inspirations and (non)aspirations, and centrally details the mixed methodologies involved in the research process. The analysis focuses on the flow of the musical.ly app as evidenced through the walk-through method and young girls' engagements with the platform as solicited through personal observations and two small focus group discussions.

This chapter aims to find an optimal way to hedge foreign exchange exposures on three main currency pairs being the EURUSD, EURGBP and EURJPY. Furthermore, it analyses the risk level of each portfolio together with its kurtosis level. This chapter also looks into the relationship between the EURUSD portfolios and the VIX level.

This study is based on a back-testing analysis over a period of seven years starting in January 2007 and ending in December 2014. Two main Foreign Exchange Premium-Free strategies were structured using the Bloomberg Terminal. These were the ‘At-Expiry Forward Extra’ and the ‘Window Forward Extra’. Portfolios were created using FX options strategies, FX spot and FX forwards. The EURUSD portfolios were also analysed and compared with the VIX level in order to see whether volatility has a direct effect on the outcome of the strategies. The statistical significance of the difference between returns of portfolios was analysed using a paired sample t-test. Finally, the histogram and distribution curve of each portfolio were created and plotted in order to provide a more visual analysis of returns.

It was found that the optimal strategies in all cases were the FX option strategies. The portfolios’ risk was analysed and indicated that optimal portfolios do not necessarily derive the lowest risk. It was also found that with a high VIX level, the forward contract was the most beneficial whilst the option strategy benefited from a low VIX level. When testing for statistical significance between returns of different portfolios, in most cases, the difference in returns between portfolios resulted to be statistically insignificant. Although some similarities were noticed in distribution curves, these differed from the normal distribution. When analysing the kurtosis levels, it is found that such levels differed from that of a normal distribution which has a kurtosis level of 3. Interpretation of such histograms, distribution curves and the kurtosis analysis was explained.
