ABSTRACT

While the South African government specifically set targets on job creation in its numerous economic strategies since the economic transition, various local studies examined the levels and trends in labour force, employment and unemployment to evaluate if these targets were met. However, the quality of employment has not been thoroughly examined. This is the first local study that fills the existing research gap by deriving a composite, multidimensional employment quality index by taking 18 indicators from seven dimensions into consideration: wage, work hours and flexibility, employment security, income security, social benefits, skills and participation. Using the 2010–16 Quarterly Labour Force Survey data, the empirical findings indicated that highly educated, white male workers aged at least 35 years, who lived in urban areas of the Western Cape and Gauteng provinces, and were involved in high skilled occupations in the formal, public sector enjoyed significantly better employment quality.  相似文献

With the increasing scarcity of natural resources, the ability to maintain quality standards during resource-scarce times becomes more critical for business performance. Theories on managing resource scarcity cannot be easily tested in contexts where resources are still abundant. This study therefore turns to an emerging market context in which natural resource availability naturally varies strongly between seasons, namely, that of Ethiopian pastoralists who for many generations learned to adapt to natural resource scarcity. Central to our theory is the natural resource deployment capability, which is the ability of a business to make efficient and effective use of available resources to maintain business performance during resource-scarce times. Using three-wave longitudinal data from 120 pastoral family-based livestock businesses, the study shows that when resources are scarce or extremely scarce, market knowledge helps to better deploy the scarce natural resources, leading to higher product quality. The findings imply that businesses with a better understanding of markets have stronger natural resource deployment capability. The lesson for businesses that are confronted with approaching resource scarcity is therefore to strengthen their ability to deploy resources efficiently and effectively by strengthening their market knowledge in which such capability is rooted.  相似文献

The paper concerns the study of equilibrium points, or steady states, of economic systems arising in modeling optimal investment with vintage capital, namely, systems where all key variables (capitals, investments, prices) are indexed not only by time but also by age. Capital accumulation is hence described as a partial differential equation (briefly, PDE), and equilibrium points are in fact equilibrium distributions in the variable of ages. A general method is developed to compute and study equilibrium points of a wide range of infinite dimensional, infinite horizon, optimal control problems. We apply the method to optimal investment with vintage capital, for a variety of data, deriving existence and uniqueness of equilibrium distribution, as well as analytic formulas for optimal controls and trajectories in the long run. The examples suggest that the same method can be applied to other economic problems displaying heterogeneity. This shows how effective the theoretical machinery of optimal control in infinite dimension is in computing explicitly equilibrium distributions. To this extent, the results of this work constitute a first crucial step towards a thorough understanding of the behavior of optimal paths in the long run.  相似文献

一般竞争战略理论对企业战略决策具有广泛而深远的影响。学者们对一般竞争战略的割裂观和融合观一直争执不休,众多研究呈现出多角度、多证据、结论矛盾和研究混乱的局面。文章通过对相关理论回顾和梳理,揭示出一般竞争战略理论割裂观存在的问题和困境,呈现融合观的理论与实证证据,提炼出混合战略的三个流派,并揭示混合战略研究的脉络和趋势。文章揭示出融合是竞争战略的趋势,实现不同战略类型的融合和竞争战略的多维体系构建,有助于厘清竞争战略研究的混乱和矛盾,打破根深蒂固的“骑墙战略”禁区思维,为企业的战略决策提供系统和多维的视角,并推动一般竞争战略从割裂化向融合化演进,特别是对现阶段的中国企业战略制定具有重要意义。  相似文献

[目的]针对全国31个省(市、区)(不含港澳台地区)、自然资源依赖度高的地区和自然资源依赖度低的地区,从整体和分区域研究自然资源依赖对城乡收入差距的影响,探究不同区域其影响程度的差异性,进而为弱化各区域城乡收入差距,解决由城乡收入差距拉大造成的各类社会矛盾具有重要的现实意义。[方法]从理论上分析了自然资源依赖对城乡收入差距的影响,并利用1999—2017年的省级面板数据,运用固定效应模型,从全国和分区域实证分析了自然资源依赖对城乡收入差距的影响。[结果]针对全国,自然资源依赖会拉大城乡收入差距; 分区域结果,针对自然资源依赖度高的地区,自然资源依赖拉大城乡收入差距; 针对自然资源依赖度低的地区,自然资源依赖对城乡收入差距影响不显著。[结论]为缩小城乡收入差距,需要降低经济体对自然资源的依赖,针对自然资源依赖度高的地区,政府通过将部分自然资源收益转化为农业创新基金和农村基础设施投入,促进自然资源收益向农村公共资本转化,完善现有的自然资源收益分配及转化制度; 鼓励资源型产业技术创新,加大研发投入,延长资源产业链; 加大农村教育投入、提升农村人力资本质量。  相似文献

This research deals with antecedents and outcomes of relationship quality in e-tail. SMART-PLS analysis of survey data from India (n = 644) showed that perceived value, e-service quality, interaction, discounts and transaction related factors were found to have a positive effect on relationship quality (RQ). RQ mediates the relationship between these antecedents and self-brand connect and loyalty. Support for serial mediation was found with RQ and self-brand connect preceding loyalty formation. Relationship duration positively moderated the effect of RQ on self-brand connect. RQ was conceptualized as a formative second order factor. E-tailers may invest in antecedents of RQ and they may devise strategies to increase the duration of relationships.  相似文献

The authors investigate the extent to which central customer-based brand equity dimensions (Differentiation, Relevance, Esteem, Knowledge, and Energy) influence a firm’s systematic risk (i.e., beta) during both market upturns and downturns. The results demonstrate that aggregating upside and downside beta or different dimensions of brand equity masks the true associations which can be seen only in the disaggregate analyses. The authors find that Relevance and Knowledge play roles as stabilizers, showing negative relationships with both upside gains and downside risk, while Esteem plays the role of protector, showing a negative relationship with only downside losses and not influencing upside gains; Energy acts as a booster, being positively associated with a firm’s potential gains in a period of market growth without increasing the firm’s expected losses during a bad market. The positive relationship of Energy with aggregate risk could be misleading as it hides the beneficial effect of Energy as a booster. The authors also find that Relevance is the most important consideration when people make choices in bad market situations, while Energy becomes the most crucial deciding factor in good market situations. Taking advantage of the multidimensional constructs of brand equity while allowing for the asymmetrical characteristics of risk enables managers to capture the differential role of each brand equity dimension in influencing firm risks, which leads to more sophisticated strategic decisions regarding risk management. In addition to general brand strategy, the authors provide tailored brand strategies to firms from different industries or with different financial characteristics.  相似文献

This paper uses the concept of psychological distance under construal level theory to explore the differences in the customers’ evaluations of overall store quality, satisfaction and loyalty, based on their experiences with the traditional staff-checkout method and the relatively new self-checkout machines. Two empirical studies, a field survey with retail shoppers in UK (N1 = 313) and an online survey with members of a consumer panel in Australia (N2 = 474), show that the perceived quality of staff-checkout has a stronger positive impact on the overall store quality, satisfaction and loyalty, than the quality of self-checkout. Similarly, satisfaction with staff-checkout has a stronger positive effect on store satisfaction and loyalty, than the satisfaction with self-checkout. Finally, loyalty to staff-checkout also has a stronger positive influence on store loyalty, than the loyalty towards self-checkout. These results show that despite growing use of self-service technology, frontline staff continue to be important for overall store evaluations.  相似文献
