Item Does the Inverse Farm Size-Productivity Hypothesis Hold Beyond Five Hectares? Evidence from Ghana(Journal of Agricultural and Applied Economics, 2022) Debrah, G.; Adanu, K.We contribute to the inverse farm size-productivity puzzle (IR) literature by examining the relationship using a unique data set from southern Ghana that covers farms between 5 and 70 ha. The study uses an instrumental variable (IV) for land size to mitigate some effects of measurement error in land size. The inverse relationship between farm size and farm productivity is upheld when ordinary least squares estimators (OLS) are applied but becomes insignificant, although still negative in the IV estimation. The results show that measurement error in land size attenuate the IR. While some studies found the IR to flatten and then become positive, this study finds that in Ghana, the IR only flattens.Item Education, skills, and duration of unemployment in Ghana(Cogent Economics & Finance, 2023) Gyan, E.Y.; Debrah, G.; Adanu, K.; Atitsogbui, E.The unmatched growth in available jobs, given the rising youth popula tion, is a major concern for policymakers in sub-Saharan African countries (SSAs), particularly Ghana. The weakness in the link between education and the needed skill by the industry, has been labelled as the cause of rising unemployment and prolonged unemployment duration in Ghana. This paper presents new evidence on the effect of education and skill—language, computer and numeracy skills—on unemployment duration in Ghana using the Skill Towards Employment and Productivity (STEP) skill dataset collected by the World Bank in 2013. The study employs Cox’s Proportional Hazard Model to examine the effect of education, language, computer and numeracy skill on unemployment duration. We found that education reduces the duration of unemployment in general. However, the effect is higher for exiting salaried work compared to self-employed jobs. Proficiency in computer, English or Ewe reduces the duration of unemployment. In particular, we observe that individuals highly skilled in computer use are 34.4% more likely to exit unemployment compared to those without computer skills. Interestingly, the effect of computer skills is through channels other than formal education.Item Education, skills, and duration of unemployment in Ghana(Cogent Economics & Finance, 2023) Yirenkyi, E.G.; Debrah, G.; Adanu, K.; Atitsogbui, E.bstract: The unmatched growth in available jobs, given the rising youth popula tion, is a major concern for policymakers in sub-Saharan African countries (SSAs), particularly Ghana.
