Adoption of crop insurance in Ghana: an application of the complementary log-log truncated Poisson double-hurdle model
(Emerald Publishing Ltd, 2021) Addey, K.A.; Jatoe, J.B.D.; Kwadzo, G.T.
Purpose – The aim of this paper is to identify the factors that influence rice farmers’ decisions to adopt crop insurance and premium payments (willingness to pay [WTP] amounts). The paper also demonstrates the usefulness of the complementary log-log (cloglog) truncated Poisson double-hurdle model as an alternative hurdle model. Design/methodology/approach – The study first investigated the nature of the dependent variable, which had non-normal residuals and was overdispersed. The probit truncated normal regression double-hurdle model was tried but it failed the normality and homoscedasticity tests; hence, the cloglog truncated Poisson double hurdle model was employed in the study. Findings – An estimated 61% of respondents would purchase crop insurance, despite farmers not having prior experience with this product. Amongst others, the factors that influence insurance adoption amongst rice farmers are the share of rice in total income, reliability perception of crop insurance schemes and the probability of failure to achieve target yields. The latter helps the authors to address adverse selection, a central issue to the viability of such an insurance programme. The determinants of farmers’ WTP are also identified. Research limitations/implications – Sampling was limited to farmers using irrigation and living in one region of Ghana, which may limit the study’s wider applicability. Originality/value – As far as the authors are aware, this study is the first to select the appropriate hurdle model based on established properties of the dependent variable on this topic – crop insurance decisions.
The Economic Cost of Malaria and the Behaviour of Farmers Towards Malaria Care in Amansie East And Kwaebibrem Districts of Ghana
(1994-09) Dzator, J.A.; Asenso-Okyere, W. K.; Al-Hassan, R.; Kwadzo, G.T.; University of Ghana, College of Basic and Applied Sciences, School of Agriculture, Department of Agricultural Economics and Agribusiness
The study focused on malaria care seeking behaviour of farm households in general. Time and money costs of care, the impact of socio-economic factors affecting health care seeking behaviour and household choice of malaria care providers were investigated.The findings show that households appear to be more sensitive to time costs in choosing malaria care providers. The report presents direct costs and indirect costs of treating an episode of malaria and also traced malaria treatment behaviour.
The Structure and Efficiency in Resource Use in Maize Production in the Asamankese District of Ghana
(University of Ghana, 1996-12) Amankwah, C. Y. G.; Kwadzo, G.T.; Al-Hassan, R.; University of Ghana, College of Basic and Applied Sciences, School of Agriculture, Department of Agricultural Economics and Agribusiness.
The study sets out to find out on one hand, the present structure of resources in agricultural production and secondly, to delve deeper into the controversy surrounding the comparative efficiency in resource use by sharecroppers and owner farmers in agricultural production. The approaches used to assess the structure of the resources are frequency distributions, descriptive analyses and estimation of cost composition of individual resources. In assessing the comparative efficiency in the use of resources by sharecroppers and owner farmers, the gross margins method and the allocative efficiency method based on the profit maximizing assumption were used. The findings of the study indicate that, there is limited use of fertilizers, weedicides and improved seeds. Cutlass is widely used. Mixed cropping is widely practiced, land areas cultivated to maize fall mostly below one hectare and the major source of labour on almost all the farms studied is the family. The study also found that there were no significant differences in the efficient use of land and labour by owner and sharecropping farmers. It is therefore concluded that the traditional way of farming based on the structure of the resources has not changed in the study district. With the efficiency in the use of land and labour by sharecroppers and owner farmers, the conclusion is that both farmer groups use land and labour inefficiently.
