- 2023| Caddo Gap PressEntrepreneurship skills acquisition has gained unprecedented importance because of its role in economic development. This study examined the influence of skill acquisition programs as a tool for economic growth in Nigeria. The study made use of two objectives which seek to find out the influence of skill acquisition on economic development and also investigate gender differences in skill acquisition on economic development. Two hypotheses were formulated, which were drawn from the objective of the study. A survey research design was adopted in the study. The population were unemployed youths in Ondo state, Nigeria. A sample size of two hundred (200) unemployed youths was selected. A simple random sampling technique was used to select the participants. A primary source of data collection was adopted, which involved the use of a self-constructed questionnaire. Results revealed that skill acquisition has a significant influence on economic development [F (l, 198) 194.24]; there is a significant gender difference in skill acquisition on economic development [t (198) =.891, p 0.05] such that male youth (M = 58.44; SD = 8.70) have the same level of skill acquisition compared to female youths (M = 41-56; SD = 7.52). It was concluded that skill acquisition programmes provided for unemployed youths have actually influenced the economic development of Nigeria. It was recommended that the government should ensure that skill acquisition centres are well equipped so as to ensure a suitable learning environment; and the government should help finance those who have undergone skill acquisition programs to enable them to set up a business to become entrepreneurs.

- 2023| Center for Strategic...The attitude that employees have towards their job is well believed to have an influence on their performance. This study investigated the influence of job satisfaction on employees' performance. Herzberg's two-factor hygiene and motivation theory was used to explain employees' motivation for best performance. A cross-sectional survey design in the form of a structured questionnaire was used to randomly sample one hundred (100) employees of the University of Zululand, South Africa. Descriptive and correlation analysis were used to analyze the collected data. The findings indicate that job satisfaction does not influence employees' performance. The study concludes that UNIZULU employees enjoy their roles despite the unsatisfactory benefits attached. In spite of the unsatisfactory level of benefits, they perform their duties effortlessly. This research contributes to research-based knowledge that will assist universities' management in identifying the factors that will enhance employees' performance.

- Population aging presents numerous challenges, such as a reduced fiscal balance, changes in the savings patterns of households, and higher age dependency ratios. These consequences are evident for older individuals, the government, and the economy at large. This study examined the impact of population aging on the economic growth of South Africa, studying the King Cetshwayo District Municipality specifically. A panel data set for the period 2002-2020 by Quantec Easy Data was used for the study. A FE regression model was used to examine the relationship between economic growth (GDP per capita), population aging, savings, education, and other independent variables. The findings from the panel data analysis revealed that population aging negatively affects economic growth only in the short run but not in the long run. Also, other factors like education, savings, and income affected economic growth in the King Cetshwayo District Municipality. This study recommends a transformation in the country’s savings by educating the population about the importance of savings in order to improve GDP per capita and the economic wellbeing of the people.

- Purpose – This study aims to test the dynamic impact of public debt and economic growth on newlydemocratized African countries (South Africa and Namibia) and compare the findings with those of newlydemocratized European countries (Germany and Ukraine) during the period 1990–2022. Design/methodology/approach – The methodology involves three stages: identifying theappropriate transition variable, assessing the linearity between public debt and economic growth and selecting the order m of the transition function. The linearity test helps identify the nature of relationships between public debt and economic growth. The wild cluster bootstrap-Lagrange Multiplier test is used toevaluate the model’s appropriateness. All these tests would be executed using the Lagrange Multipliertype of test. Findings – The results signify the policy switch, as the authors find that the relationship between public debt and economic growth is characterized by two transitions that symbolize that the current stage of the relationship is beyond the U-shape; however, an S-shape. The results show that for newly democratized African countries, the threshold during the first waves was 50% of GDP, represented by a U-shape, which then transits to an inverted U-shape with a threshold of 65% of GDP. Then, for the European case, it was 60% of GDP, which is now 72% of GDP. Originality/value – The findings suggest that an escalating level of public debt has a negative impact on economic growth; therefore, it is important to implement fiscal discipline, prioritize government spending and reduce reliance on debt financing. This can be achieved by focusing on revenue generation, implementing effective taxation policies, reducing wasteful expenditures and promoting investment and productivity enhancing measures.

- The implications of population aging on local health care expenditure: a 22-year panel data analysisThe purpose of this study is to examine the implications of population aging on local health expenditures in South Africa. A balanced panel of annually observations from South Africa over the period of 22 years (1995–2017) was used. The study used gross domestic product (GDP), health expenditure, labor force, and age structure as control variables and pooled OLS, fixed effect, and random effect tests to estimate the relationships among the variables. The results show that the old-age dependency ratio, gross domestic product (GDP), unemployment rate, and gross value added (GVA) are all explanatory variables that are related to healthcare spending and are shown as a base model in the pooled OLS. The results indicate that healthcare expenditure and the old-age dependency ratio have a positive relationship in South Africa. Considering the implications for policy, this study suggests that the South African economy should account for the aging population when policies are designed and that the government should make an effort to improve the healthcare system in order to meet the demands of elderly people.

- A panel data analysis of nonlinear financial growth dynamics in a macroprudential policy regime was conducted on a panel of 10 African emerging countries from 1985–2021, where there had been a non-prudential regime from 1985–1999 and a prudential regime from 2000–2021. The paper explored the validity of the inverted U-shape hypothesis in the prudential policy regime as well as the threshold level at which excessive finance boosts growth using the Bayesian Spatial Lag Panel Smooth Transition Regression (BSPSTR) model. The BSPSTR model was adopted due to its ability to address the problems of endogeneity and heterogeneity in a nonlinear framework. Moreover, as the transition variable often varies across time and space, the effect of the independent variables can also be time- and space-varying. The results reveal evidence of a nonlinear effect between finance and growth, where the optimal level of financial development is found to be 92% of GDP, above which financial development decreases growth. The findings confirmed the Greenwood and Jovanovic hypothesis of an inverted U-shape relationship. Macroprudential policies were found to trigger the finance–growth relationship. The policy recommendation is that the financial sector should be given adequate consideration and recognition by, for example, implementing appropriate financial reforms, developing a suitable investment portfolio, and keeping spending on technological investment in Africa’s emerging countries below the threshold. Again, caution is needed when introducing macroprudential policies at a low level of the financial system.

- Changes in population structure can have a great impact on savings rates. This study investigated the relationship that exists between the aging population and the savings rate in South Africa. The gross savings of South Africa from 1995 to 2017 was analysed. A fixed effect model and a random effect model were used as baselines for arbitrary correlations between unobserved heterogeneity and independent variables. The Hausman test was utilized to find a more efficient and consistent model that produces consistent results. The argument of the Lice Cycle Hypothesis developed by Modigliani (1970) and those previous research findings in which the rising older population has a tendency to decrease the rates of savings were followed in this paper. The findings revealed that an increase in old-age dependency does not cause the level of savings to decline but will rather lead to an increase in savings. The findings agree with the bequest theory, which states that old people save up their money for their upcoming generation. Due to the findings obtained in this paper, economic policies that aim to increase savings through demographics might not be relevant and are therefore not suggested.

- Studying the impact of aging on GDP per capita does not give a clear picture of the economic wellbeing of elderly people. GDP per capita does not cater for people’s level of development or improvements in their standard of living. As a result, it is not a reliable measure of wellbeing. Each person has a different perspective regarding their economic wellbeing, and as a result, this study examines the impact of population aging on the economic wellbeing of the elderly in the King Cetshwayo District Municipality. A cross-sectional data set consisting of one hundred and fifty (150) participants was utilized to explore the determinants of economic wellbeing. Househeads aged 60 and above were asked questions about their demographics, level of education, asset ownership, and affordability of basic needs. The logistic regression model was used to examine the relationship between economic wellbeing and independent variables like age, gender, level of education, household savings, and other variables. The findings revealed that population aging does not affect the economic wellbeing of the elderly. Economic wellbeing was found to be determined by factors such as gender, education, health care expenditure, household savings, and increases in price levels.

- Learning entrepreneurial skills has taken on a significance never before seen as a result of their significance to economic growth. In this study, the impact of skill development initiatives on Nigeria's economic development was examined. The study used two objectives: to look into how gender differences in skill acquisition affected economic development and to determine how skill acquisition affected economic development. A quantitative method in the form of a questionnaire was used to sample two hundred (200) unemployed youths. Results revealed that there is a significant gender difference in skill acquisition for economic development and that skill acquisition has a significant influence on economic development. The study concluded that youths perceive skill acquisition programmes to have a positive effect on employment creation. Likewise, gender equality is to be considered in skills acquisition training. In general, the involvement of both genders in skill acquisition programmes will go a long way toward improving the nation's economic development.
