This research paper investigates the influence of Gender in management on the level of efficiency of food crop farms in Ghana. The study specifically: compares the technical efficiency scores of farms with male entrepreneurs and those with female entrepreneurs; examines the determinants of technical efficiency of food crop farmers; and compares technological gaps of farms with male entrepreneurs and those with female entrepreneur. The study involved 90 male food crop farmers and 90 female food crop farmers in the Juaboso District in the Western Region of Ghana. The respondents interviewed were selected using stratified random sampling technique. Stochastic metafrontier production function was used to estimate the efficiency scores in each group and multiple regression models was estimated to verify the determinants of technical efficiency. Survey was conducted with structured interview schedules to collect data. The estimated technical efficiencies indicate that food crop farmers in the Juaboso District of Ghana are, in general, less efficient in their production. Although farms under male farmers management had higher mean value of production figures relative to the female farmers' farms, the farms under female farmers management were found to be more efficient and also nearer to the potential output defined by the metafrontier production function compared to the farms owned by males. We also found technical efficiency to be influenced significantly by gender, age, household size, years of farming experience, access to credit, education and consultation with extension staff.

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.

Employing discrete choice models, data from the Ghana Statistical Service (specifically, the fifth round of the Ghana Living Standard Survey) are used for the analysis. In addition to providing a quantitative analysis of the determinants of travel propensity, which had not previously been examined for Ghana, the authors test two hypotheses. First, they assert a three-way (positive–negative–positive) relationship between age and travel propensity. Second, they argue that the mother’s education is more likely to influence the decision to travel than the father’s education. The travel patterns of Ghanaians were found to bear the inherent hallmarks of domestic tourism. The authors also observe that, although the degree of travel is low, the frequency of repeat visits is high. Social imperatives dominated the motives for travel, while key socio-demographic variables (especially the respondent’s age) were found to influence travel propensities significantly.

This study hypothesized that climate variability affect input substitutability and technological differential of maize farms across agro-ecological zones in Ghana. A metafrontier production function model for farms in different agro-ecological zones having different technologies were analyzed. Using cross-sectional data from 622 farmers across the three major agro-ecological zones, we found that all maize farms across the agro ecological zones are less efficient. However, farms in the forest zone have higher efficiency scores than farms within coastal and savannah zones. Farms in the coastal and savannah zones are closer to their potential output defined by the metafrontier function than farms within the forest zone. The stochastic frontiers for all farms within coastal and savannah zones are tangent to the stochastic metafrontier. Farms within coastal and savannah zones use more advanced technology than farms within the forest zone as indicated by the intercept term in the production function. Policy makers should ensure that climatic conditions prevailing in the different agro ecological zones across the country are taken into consideration while formulating agricultural policy. Since climate variability may have either positive or negative effects on these policies as well as farm technologies used.

A sample of 400 Batik producers was interviewed for the purpose from the Central Region of Ghana. The Stochastic Frontier approach was used in determining the levels of technical efficiency of the Batik producers, after which the determinants of the technical efficiency were also estimated. Results indicate that the mean technical efficiency of Ghana’s batik production industry was 66.5 percent on the average: ranging from 8.4 to 99.6 percent. The wide variation in the level of efficiency suggests that there was ample opportunity for these enterprises to raise their level of efficiency. The level of education, business experience, and training programs of entrepreneur and accessibility to credit were found to be highly positively significant in affecting the level of efficiency of the batik enterprises. The study suggest that more resources be invested in the training of the entrepreneurs, access to credit should be improved, to increase the technical efficiency of batik entrepreneurs in Ghana.nter Abstract Body]

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.

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.

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 ye...

To understand the choice of adaptation strategies farmers adopted, the study used a cross-sectional data from 622 randomly selected farmers from 18 villages across the three major agro ecological zones using structured questionnaire. The study hypothesized that farm characteristics, climatic variables and extreme weather events had no significant influence on farmers' choice of various adaptation strategies across agro-ecological zones. To capture the factors that influence the choice of adaptation strategies, the study employed the Multinomial logit Model. The results indicated that irrigation farming, income-generating activities, crop diversification, tree planting and shifting planting dates are some of the adaptation strategies farmers used to adapt to changes in the weather and other related factors. The study recommends, therefore, the intensification of the use of these adaptation strategies through support from government and other stakeholders to help the farmers to cope very well with the vagaries of the weather and improve food crop production in Ghana.
