Aim: To examine the hypothesis that circular labour migrants who become seriously ill while living away from home return to their rural homes to convalesce and possibly to die. Methods: Drawing on longitudinal data collected by the Agincourt health and demographic surveillance system in rural northeastern South Africa between 1995 and 2004, discrete time event history analysis is used to estimate the likelihood of dying for residents, short-term returning migrants, and long-term returning migrants controlling for sex, age, and historical period. Results: The annual odds of dying for short-term returning migrants are generally 1.1 to 1.9 times (depending on period, sex, and age) higher than those of residents and long-term returning migrants, and these differences are generally highly statistically significant. Further supporting the hypothesis is the fact that the proportion of HIV/TB deaths among short-term returning migrants increases dramatically as time progresses, and short-term returning migrants account for an increasing proportion of all HIV/TB deaths. Conclusions: This evidence strongly suggests that increasing numbers of circular labour migrants of prime working age are becoming ill in the urban areas where they work and coming home to be cared for and eventually to die in the rural areas where their families live. This shifts the burden of caring for them in their terminal illness to their families and the rural healthcare system with significant consequences for the distribution and allocation of health care resources.

provide a powerful lift to growth—both in the short and the long term—if they are well aligned with individual country conditions . These include an economy’s level of development, its position in the economic cycle, and its available macroeconomic policy space to support reforms. The larger a country’s output gap, the more it should prioritize structural reforms that will support growth in the short term and the long term—such as product market deregulation and infrastructure investment. Macroeconomic support can help make reforms more effective, by bringing forward long-term gains or alleviating their short-term costs . Where monetary policy is becoming over-burdened, domestic policy coordination can help make macroeconomic support more effective. Fiscal space, where it exists, should be used to offset short-term costs of reforms. And where fiscal constraints are binding, budget-neutral reform packages with positive demand effects should take priority. Some structural reforms can themselves help generate fiscal space. For example, IMF research finds that by boosting output, product market deregulation can help lower the debt-to-GDP ratio over time. Formulating a medium-term plan that clarifies the long-term objectives of fiscal policy can also help increase near-term fiscal space. With nearly all G-20 economies operating at below-potential output, the IMF is recommending measures that both boost near-term growth and raise long-term potential growth. For example: ? In advanced economies, these measures include shifting public spending toward infrastructure investment (Australia, Canada, Germany, United States (US)); promoting product market reforms (Australia, Canada, Germany, Japan, Korea, Italy) and labor market reforms (Canada, Germany, Japan, Korea, United Kingdom (UK), US); and fiscal structural reforms (France, UK, US). Where there is fiscal space, lowering employment protection is also recommended (Korea). ? Recommendations for emerging markets (EMs) focus on raising public investment efficiency ( India, Saudi Arabia, South Africa), labor market reforms (Indonesia, Russia, Saudi Arabia, South Africa, Turkey), and product market reforms (China, Saudi Arabia, South Africa), which would boost investment and productivity within tighter budgetary constraints particularly if barriers to trade and FDI were eased (Brazil, India, Indonesia). Governance (China, South Africa) and other institutional reforms are also crucial. Where policy space is limited, adjusting the composition of fiscal policy can create space to support reforms ( Argentina, India, Mexico, Russia). ? Some commodity-exporting EMs (Brazil, Russia, Saudi Arabia, South Africa) are facing acute challenges, with output significantly below potential and an urgent need to rebuild fiscal buffers. To bolster growth, Fund staff recommends product market and legal reforms to improve the business climate and investment; trade and FDI liberalization to facilitate diversification; and financial deepening to boost credit flows. IMF advice also aims to promote inclusiveness and macroeconomic resilience. The Fund recommends a targeted expansion of social spending toward vulnerable groups (Mexico), social spending for the elderly poor ( Korea), and upgrading social programs for the nonworking poor (US). Recommendations to bolster macrofinancial resilience include expanding the housing supply (UK), resolving the corporate debt overhang (China, Korea), coordinating a national approach to regulating and supervising life insurers (US), and reforming monetary frameworks (Argentina, China).

In this paper, we propose a stochastic investment model for actuarial use in South Africa by modelling price inflation rates, share dividends, long-term and short-term interest rates for the period 1960–2018 and inflation-linked bonds for the period 2000–2018. Possible bi-directional relations between the economic series have been considered, the parameters and their confidence intervals have been estimated recursively to examine their stability, and the model validation has been tested. The model is designed to provide long-term forecasts that should find application in long-term modelling for institutions such as pension funds and life insurance companies in South Africa Keywords: Stochastic investment models; price inflation; share dividend yields; share dividends; share prices; long-term interest rates; short-term interest rates; inflation-linked bonds; South Africa

The state-owned power utility, Eskom, generates about ninety five percent of the electricity produced in South Africa. Plans by the government of South Africa in the mid-nineteen nineties to restructure the electricity industry in the country prevented Eskom from embarking on capacity expansion activities when it was necessary. Load growth, as a result of economic growth and a national electrification programme, caused an erosion of the electricity reserve margin, which was quite massive in the early nineties. The large reserve margin then caused Eskom to reduce operating capacity by mothballing some generating plants and putting them in reserve storage. The current situation is that the reserve margin has dropped to about 17,4 percent and a capacity expansion programme is underway. Though the apparent reserve margin is within the desired range, plant unavailability has diminished the reserve margin in real terms and this does not leave Eskom with much room for planned maintenance and a buffer to manage unplanned maintenance, the result being that plant incidents and technical problems cannot easily be absorbed within the power system to avoid interruption of supply. Also, the new environmental legislation does not help the situation, as it has the potential to shut down generating plants that do not meet the new emissions standard. In addition, there have been problems with the New Build Programme that caused a delay, of over three years, in the delivery of new power, and to compound the problem the Energy Regulator refused recently Eskom’s application for additional tariff increase, which was requested to enable the company provide the finances to cover the shortfall in funding for operational expenses and the New Build Programme. As such, Eskom faces many challenges in meeting its obligation to South Africa, and interventions are in place to manage the situation. In the short term, the key to generation sustainability is improved plant health, brought about by on-time maintenance and correctly-scoped and no-slip outages. This paper presents an overview of the power situation in South Africa, explaining where the country has come from, the plan for long term security of supply, and the challenges faced by Eskom from the generation supply side in meeting the demand load in the short term. Trends in the performance indices indicative of plant health are examined and it is argued that executing planned plant maintenance will improve plant health and, hence, plant availability, which can bring about a turnaround in the short term power supply situation, as Eskom awaits new capacity from the New Build Programme.

South Africa's national railway management is considering the further closing of a number of branch lines due to profitability pressures from stakeholders. This paper cautions against a myopic approach to such closures. Traditionally these decisions are driven by short-term profit motives realised through resulting core line densification. The research presented in this paper demonstrates the importance of 1) taking cognisance of potential branch lines flows; 2) considering freight transport externalities and road usage costs; and 3) understanding long-term demand, in informing closure decisions. The research results reveal considerable volume opportunities for branch lines which, if captured, will significantly reduce both the direct transport costs for this traffic as well as externality charges for the economy. This will therefore not only render rural economies more competitive but also enable the provision of more sustainable freight transport to these communities. The research approach will be of value to researchers in both developed and developing economies to inform the continuous debate regarding rail rationalisation and rail revival.

SummaryWithout a doubt, the 2010 World Cup of soccer in South Africa was a great experience for both soccer fans, who enjoyed a safe and efficiently-run tournament, and their South African hosts. The sporting and social spectacle was broadcast around the world and focused unprecedented media attention on South Africa. Despite the manifest success of the tournament, its short-term effects on international tourism, which are the nucleus of all other short-term positive effects on economic variables such as employment, income and taxes, have turned out to be of a much smaller magnitude than expected or even as reported during the tournament. This may be attributable to self-defeating prophecy effects. This study is a warning against the abuse of economic impact studies, especially those pertaining to major sporting events. It is also a call to use the “correct” arguments of measurable awareness effects and potential long-term development effects in discussing major sporting events. Methodologically, this study is innovative in its economic analysis of major sporting events because it (i) uses data from social networks and (ii) uses high-frequency daily data on tourism.

We supply a new perspective to describe and understand the behavior of cross-correlations between energy and emissions markets. Namely, we investigate cross-correlations between oil and gas (Oil-Gas), oil and CO2(Oil-CO2), and gas andCO2(Gas-CO2) based on fractal and multifractal analysis. We focus our study on returns of the oil, gas, andCO2during the period of April 22, 2005–April 30, 2013. In the empirical analysis, by using the detrended cross-correlation analysis (DCCA) method, we find that cross-correlations for Oil-Gas, Oil-CO2, and Gas-CO2obey a power-law and are weakly persistent. Then, we adopt the method of DCCA cross-correlation coefficient to quantify cross-correlations between energy and emissions markets. The results show that their cross-correlations are diverse at different time scales. Next, based on the multifractal DCCA method, we find that cross-correlated markets have the nonlinear and multifractal nature and that the multifractality strength for three cross-correlated markets is arranged in the order of Gas-CO2 > Oil-Gas > Oil-CO2. Finally, by employing the rolling windows method, which can be used to investigate time-varying cross-correlation scaling exponents, we analyze short-term and long-term market dynamics and find that the recent global financial crisis has a notable influence on short-term and long-term market dynamics.

We used the Bootstrap Autoregressive Distributed Lagged Model (ARDL) method to test the relationship among BRICS (Brazil, Russia, India, China, and South Africa) countries’ trade, foreign direct investment (FDI), and CO2 emissions. We found that Brazil’s CO2 emissions and FDI have a cointegration relationship with the trade on the lag of one-period. Russia and India and CO2 emissions and trade have a cointegration relationship with FDI on the lag of one-period. In the long-term, Brazil’s FDI has a long-term causal relationship with the trade on the lag of one-period. The trade between Russia and India has a long-term causal relationship with FDI on the lag of one-period. Among other BRICS variables, Russian trade and FDI on the lag of one-period of CO2 emissions and FDI and CO2 emissions are on the lag of one-period on trade, which McNown et al. mentioned is the degeneration case #1 in their paper; while China’s trade and FDI on the lag of one-period of CO2 emissions is the country of degeneration case #2. When we examined short-term causality, we found that CO2 emissions showed a causal relationship with trade, while FDI and CO2 emissions were less pronounced. Trade has a positive causal relationship with FDI. These variables are different in different situations and in different countries. These results should be related to BRICS countries’ FDI, international trade development, and their different CO2 emission policies.

In South Africa tourism is regarded as a growth catalyst and a contributor towards the economic upliftment of poorer regions. The magnitude of the impact of tourist spending depends on the extent of leakages from the region, and the ability of the region to create backward and forward linkages. It is argued that the spatial implications of tourism might, inter alia, depend on the relative impacts of domestic versus international tourist spending. Using an input-output model, support was found for the notion that, from a regional development perspective, there should be an emphasis on the development of the domestic tourism market in the short term. As a long-term strategy, investment in transport services and infrastructure to reduce path dependency effects, more inherent in international tourism, is proposed.
