Obtaining a representative sample size remains critical to survey researchers because of its implication for cost, time and precision of the sample estimate. However, the difficulty of obtaining a good estimate of population variance coupled with insufficient skills in sampling theory impede the researchers’ ability to obtain an optimum sample in survey research. This paper proposes an adjustment to the margin of error in Yamane’s (1967) formula to make it applicable for use in determining optimum sample size for both continuous and categorical variables at all levels of confidence. A minimum sample size determination table is developed for use by researchers based on the adjusted formula developed in this paper.

This study examines how financial literacy, financial behaviour, family support (as another source of income), number of dependents, and retirement planning influence on the financial well-being of retirees in Cape Coast Metropolis of Ghana. A cross-sectional survey strategy was employed on 400 respondents randomly selected from 1500 members of the association to analyze the effect of financial literacy, financial behaviour, family support, number of dependents and retirement planning on financial wellbeing. It then tests their hypothesized relationships with the use of Partial Least Squares (PLS), a structural equation modelling technique. The results reveal that financial literacy, retirement planning and family support significantly impact the financial well-being of retirees. More importantly, the effect of family support and retirement planning on retirees' financial well-being is stronger than the one of financial literacy. The findings imply that finance literacy and retirement planning should be promoted. In addition to policies aimed at bridging social cohesion and promoting family values should not be ignored the maximizing of financial well-being of retirees. The study contributes to the extant literature on financial literacy and provides evidence on the effect of financial literacy and financial planning on the financial well-being of retirees in a developing country. It has also provided support for the need of social cohesion.

Purpose: This study examines the associations between financial inclusion, health-seeking behavior, and health-related outcomes in older persons in Ghana. Method: Employing data from a 2016/2017 Aging, Health, Psychological Well-Being and Health-Seeking Behavior Study ( N = 1,200; mean age = 66.2 years [standard deviation = 11.9], we estimated regression models of self-rated health (SRH), psychological distress (PD), and health-care use (HCU) on a variable representing compositional characteristics of financial inclusion. Results: Multivariate logistic and generalized Poisson models showed that financial inclusion is positively associated with SRH (β = .104, standard error [ SE] = .033, p < .001) but inversely related to both PD (β = .038, SE = .032, p < .005) and HCU (β = −.006, SE = .009, p < .05) independent of other factors. However, after adjusting for socioeconomic and health-related factors, the associations were tempered and the effect of SRH decreased by 0.094 and PD increased by 0.065 points but HCU became statistically insignificant (β = −.020, SE = .0114, p > .05) Conclusions: Financial services inclusion profoundly appears to buffer against and retard health-related challenges in later life. Social and health policies targeted at improving the health outcomes of older people should include and build on the growing recognition of the importance of inclusive financial services and strategies.

This study investigated the impact of the novel coronavirus disease 2019 (COVID‐19) outbreak on prices of maize, sorghum, imported rice and local rice in sub‐Saharan Africa (SSA). We estimated dynamic panel data models with controls for macroeconomic setting using general method of moments estimation. The study found that the COVID‐19 outbreak led to increases in food prices of the sampled countries. Restrictions on movements or lockdowns in the wake of COVID‐19 was associated with an increase in the price of maize only. We also found that exchange rate, inflation and crude oil prices exerted a detrimental effect on food prices. We recommend that governments of SSA countries invest in infrastructure that improves efficiencies in the food supply chain during pandemics. Providing adequate support to industries in the value chain will also improve food availability and food price stability post‐COVID‐19.

This study contributes to the scant finance literature on information flow from international economic policy uncertainty to emerging stock markets in Africa, using daily US economic policy uncertainty as a proxy and the daily stock market index for Botswana, Egypt, Ghana, Kenya, Morocco, Nigeria, Namibia, South Africa, and Zambia from 31 December 2010 to 27 May 2020, using the Rényi effective transfer entropy. International economic policy uncertainty transmits significant information to Egypt, Ghana, Morocco, Namibia, and South Africa, and insignificant information to Botswana, Kenya, Nigeria, and Zambia. The asymmetry in the information transfer tends to make the African market an alternative for the diversification of international portfolios when the uncertainty of the global economic policy is on the rise. The findings also have implications for the adoption of open innovation in African stock markets.
