In 2014 democracy in South Africa was 20 years old. The democratic government in 1994 inherited both a high and increasing public debt/gross domestic product ratio and significant development backlogs. The government had to establish fiscal sustainability, yet also pursue development in a sustainable way. This article explores the government's performance in reconciling fiscal sustainability with sustainable development. The article shows that fiscal policy has been sustainable over the 20 years, with some risks appearing towards the end, and that the government pursued sustainable development through reallocating resources within the budget and by spending more in real terms. Three phases can be identified: 1994–2000, 2001–08 and 2009–13. However, poor service delivery and low levels of government investment during the 20 years threaten to undermine economic growth. Lower growth consequently threatens the sustainability of both fiscal policy and development, which, in turn, again undermines growth prospects. Hence, the article also identifies key future challenges.  相似文献

The disproportionate concentration of healthcare professionals in urban areas is a concern in many countries, including Canada. A need to address this rural care gap has driven a large number of government led initiatives worldwide over the years. This paper presents a model that can be used as a tool to examine the efficacy of such policies on the workforce distribution in the long term. A small system dynamics model is employed to simulate the current and future distribution of general physicians at a jurisdictional level. The model represents the transition of general practitioners to provide insight into the dynamics of care provision over time. The movement, and competition, between rural and urban areas is modeled to enable detailed exploration of the ability for proposed measures to alleviate the care gap in the future. Among the tested policies are such commonly used initiatives as financial incentives to rural professionals, promotion of medical education in rural areas, expansion of rural education programs and the engagement of international medical graduates etc. We demonstrate how the model can be used as a tool to determine an efficient and well-chosen combination of policies which can help alleviate the rural care gap in the future, given that some policies are more effective than others alone but also combined with other initiatives. The presented small system dynamics model is tested on Canada's reality, but its simple nature lends itself to easy application to other countries that experience a similar problem.  相似文献

Customer relationship management (CRM) is the widely accepted approach for gathering, examining, understanding and translating information related to customers into managerial action. CRM is investigated in the context of new product performance (NPP). CRM enhances NPP as well as firm performance. This study investigates the impact of CRM on NPP through the moderation of top management support and an innovative culture, as well as the impact of CRM on firm performance through the mediation of NPP. A questionnaire survey is used for data collection from marketing managers of 159 firms in Pakistan in the B-to-B market. Hypotheses were tested using SEM in SMART PLS. This research shows that CRM directly affects firm performance, while NPP partially mediates the relationship of CRM and firm performance. These findings have significant implications for the practitioner. This study delivers insights to managers and academicians about the role of CRM in enhancing NPP and improving firm performance. In general, the study provides new insights into CRM by integrating top management support and an innovative culture. The research extends our understanding that top management support and innovative culture do not moderate the relationship of CRM with new product performance in a B-to-B context.  相似文献

This paper investigates factors preventing inter-industry labor reallocation by estimating the determinants of inter-industry worker flow and earnings change after a job change. We find that the difference in required tasks is an important reason for earnings reduction after an inter-industry job change, and thus, workers may hesitate to move to industries requiring a different set of tasks for fear of losing the wage premium acquired by task-specific human capital. In addition, more workers switch to industries with which their previous industry had larger transactions, although it affects earnings changes only marginally. On the other hand, industry performance does not affect labor inflow or wage changes significantly for inter-industry job changes. Young men, less educated women, and those quitting previous jobs for family or health reasons are more likely to move to industries requiring a different set of tasks, and young individuals who lost their jobs involuntarily are less likely to do so. Individuals more likely to move are not necessarily those whose earnings loss associated with the move is small: earning losses associated with task distance are relatively small among younger and less educated workers and are uncorrelated with the reasons for quitting the previous job.  相似文献
