The joint effect of human capital and income inequalities on HIV/AIDS prevalence: An exploratory investigation

The evidence of higher income inequality leading to increased HIV prevalence through channels of coercion and migration has emerged. This coupled with previously established macroeconomic impact of HIV/AIDS connotes reverse causality that is likely to develop a cyclical effect. The plausible cyclicality can be identified through the mergence of a three stage relationship. Initially from income inequality to HIV prevalence; then from HIV prevalence to reduced human capital formation and subsequently generating human capital inequality via reduced investment in human capital of affected households and back to income inequality. We hypothesize that the effect of this plausible cyclicality is likely to increase the effect of income inequality on HIV prevalence. Our aim is to assess the effect of productivity gaps measured by human capital dispersion on the relationship between income inequality and HIV prevalence. Deriving 1999 dataset on human capital dispersion which is measured by years of schooling, quality of school system and rates of return for 99 countries, we estimate its linear dependence effect with income inequality on HIV prevalence. We find a more significant and increased effect of income inequality on HIV prevalence of more than three times. This study sets the platform for using current datasets and generates a policy discussion for addressing productivity gaps as one of HIV/AIDS interventions.HIV/AIDS Prevalence; Human Capital; Inequality; Income ; Education

Does Access and Use OF Financial Service Smoothen Household Food Consumption?

The study relies on Ghana’s Living Standard Measurement Survey to test the hypothesis of no relationship between credit and household food consumption expenditure. We use single stage and pooled least squares given the non-availability of national panel data in Ghana and lack of better instruments in the Living Standard data. While cognisant of the adverse effect of endogeneity we observe that our finding fails to provide enough evidence to reject the null hypothesis. This suggests that access to credit does not contribute to the smoothening of household consumption. This observation cuts across different sub-samples based on socio-economic classification. We recommend caution in propagating the ability of credit in smoothening consumption.FINANCE, HOUSEHOLD, CONSUMPTION, INCOME

Demand for cooking fuels in a developing country. To what extent do taste and preferences matter?

Overreliance on biomass energy, such as firewood and charcoal, for cooking in developing countries has contributed to high rates of deforestation and resulted in substantial indoor pollution which has negatively impacted the health of many individuals. However, the effectiveness of public policies aimed at encouraging households to switch to cleaner fuels, such as liquefied petroleum gas (LPG) and kerosene, hinges on the extent to which they are mentally committed to specific fuels. Using data on four cooking fuels (charcoal, firewood, LPG, and kerosene) from the Ghana living standards survey, we found strong evidence that the most preferred fuel is LPG, followed by charcoal, with kerosene the least preferred. In addition, with the exception of kerosene that has price-elastic demand, the price elasticities of demand for the fuel types examined are inelastic. This finding suggests the so-called fuel-ladder is not robust.Demand for fuel Taste and preferences Ghana

Optimum fisheries management under climate variability: Evidence from artisanal marine fishing in Ghana

In most coastal developing countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could impact the environmental carrying capacity of the fish stock. This study investigates the effect of climate variation on biophysical parameters and yields. Our results indicate that the rising temperature is decreasing the carrying capacity. As a result, an optimum tax on harvest must reflect climate variability, as well as the congestion externality

The joint effect of human capital and income inequalities on HIV/AIDS prevalence: An exploratory investigation

This paper assessed the effect of human capital on the relationship between income inequality and HIV prevalence. We used 1999 dataset on human capital dispersion which was measured by years of schooling, quality of school system and rates of return for 99 countries. Using regression analysis, linear dependence effect of human capital and income inequality on HIV prevalence was estimated. The linear dependence yielded a relatively bigger effect than the independent effects of human capital and income inequality. This calls for addressing productivity gaps as one of the interventions of HIV/AIDS

Traditional beliefs and willingness to pay for improving a mining-polluted river in Ghana

Pollution of water resources is a widespread challenge across the globe which requires effective policy measures. However, in many instances, state institutions are weak in addressing these problems. One then wonders what alternative management regimes can be used in place of public policies. This study examined the willingness to pay (WTP) for the improvement of the Ankobra River, a mining-polluted river in the Western Region of Ghana, using the contingent valuation method. Primary data was collected from 611 respondents from 8 communities in the Prestea-Huni Valley Municipality and were analysed using probit and interval regression models. The findings suggest that respondents were concerned about the current polluted state of the Ankobra River and traditional beliefs regarding the spiritual value of the river were still very relevant to them. Consequently, respondents with the belief that the river is an abode of gods as well as natives who believe that Ankobra River is a god were more likely to pay for the improvement of its water quality. Surprisingly, respondents who believed that the river is a god had a lower WTP. Income, natives, existence value, secondary and tertiary education also had positive significant association with WTP, older respondents were less likely to pay while respondents with bigger household sizes, and the divorced had lower WTP. The estimated mean WTP for water quality improvement of the Ankobra River is GHC 51.52 ($6.62) per annum. Local community involvement in policy decision-making regarding water resources is key
