This study investigates the impact of COVID-19 on bank borrowers across 22 Arab economies from 2017 to 2022, employing the two-step system GMM estimator. The findings reveal a significant negative effect of COVID-19 on the number of bank borrowers, highlighting a sharp decline in borrowing activity due to the pandemic’s economic disruptions. Notably, the decline was more pronounced in non-GCC countries, where economic structures and pandemic responses differed. Robustness tests, including subsample analysis and alternative econometric models (pooled OLS, fixed effects, random effects, and 2SLS), consistently confirm these results. The study emphasizes the need for targeted policy interventions to stabilize financial systems, reduce borrowing costs, and control exchange rate fluctuations to maintain credit access during crises. The findings provide crucial insights for policymakers aiming to support economic recovery and strengthen the resilience of the banking sector in the face of future external shocks.

The paper examines how the growth of entrepreneurship affects the generation of employment opportunities in Nasarawa State. Even though entrepreneurship is crucial for generating employment, there are still obstacles in the way of its growth. These include limited support from governmental and non-governmental organizations, difficulty obtaining financing and microcredit, proper training and enlightenment etc. The objective of this paper is to investigate how the growth of entrepreneurship affects the creation of jobs in Lafia, Nasarawa State. The study used a descriptive research design, and the means used for gathering data was a questionnaire given to new entrepreneurs in Lafia, Nasarawa State. A sample size of 375 was determined from a population of 1604 using a Smith (1984) sampling formula; this sample represented the number of questionnaires that were delivered. This findings of the research demonstrated that the creation of jobs in Nasarawa State is significantly impacted by the growth of entrepreneurship. This implies that through entrepreneurship development, self-reliance and employment opportunities have been created in Lafia, Nasarawa State. Through this, youths have been able to develop a way to create value in the society. More so, this study revealed that access to credit (micro credit) has a significant effect on employment creation in the State. Having acquired knowledge on how to manage finance they make sound financial decisions. Lastly, the study showed that the number of new businesses established has a significant effect on employment creation in Nasarawa State. This result implies that youths who apply their entrepreneurship skills and creativity in one nature of business or the other have been able to earn a living out of it in Nasarawa State. This paper thus suggests that the Nasarawa State government should genuinely recognize the relevance of entrepreneurship development and provide an enabling environment. Both the government and institutions should ensure that youths get adequate financial credit (micro-credit).

Recent research has demonstrated that many mean-variance and shortfall-based optimal portfolio selection fail to out-perform the Naive (1/n) Portfolio in out-of-sample testing. This paper revisits this line of inquiry by applying the Naive and Sharpe Portfolios to 1100 sector-specific S&P 500 re-sampled data sets from the 2007-2021 time frame. Using April 2020 as the baseline train-test split break point, the Naive Portfolio delivers statistically significantly superior Sharpe Ratios in the test data in ten of the eleven sectors. However, the Sharpe Portfolio delivers statistically significantly superior shortfall values in all eleven sectors in the test data. Using March 2020 and May 2020 as alternative breakpoints gave similar results to the baseline analysis. Interestingly, when the data set was truncated at February 2020 (i.e., before the Covid correction) the Sharpe Portfolio returned statistically significantly better Sharpe Ratios than the Naïve Portfolio in the test data in all but the Energy sector; as in the baseline analysis, the Sharpe Portfolio returned statistically significantly superior shortfall values for all eleven sectors. Thus, the Sharpe Portfolio can deliver acceptable out-of-sample performance, but the conditions for success appear to vary by sector and test data erraticism.
