Item Christological Foundations of the New Testament and Contemporary African Christology(Ghana Journal of Religion and Theology (GJRT), 2006) Martey, E.In this article, the author underscores the fact that every Christological discussion must begin with the New Testament foundation and evidence about Jesus the Christ of God. Following Reginald Fuller's trajectory of thought, the author sees the Christology of the New Testament Church developing the three phases upon which three Christo logical paradigms can be discerned. It is from these paradigms, say the author, that 'we get the fullest pattern of Christology ' and 'we are provided with the Christological foundations of the theologies of the New Testament writers'. The writer again points out that it was this same paradigm that the ontological statements of the Church Fathers followed at Nicaea and Chalcedon; and it is the same foundation that African theologians are following today in their search for who Jesus is and what He does for African. Taking the title 'Son of God' as an example, the authoulI1derlines that the African worldview and thought-forms are shedding great lights on New Testament Christo logical titles and concepts.Item Ecological shocks and children’s school attendance and farm work in Ghana(World Development Perspectives, 2023) Martey, E.; Etwire, P.M.; Armah, R.; et al.Accelerating the education of children and reducing child labor in agriculture remains an important development pathway to preventing intergenerational poverty and achieving the sustainable development goals. While several studies have analyzed the impact of ecological stressors on yield, income, and food security, there is limited understanding of the linkages of prevailing ecological shocks to child education and farm work. In this paper, we examine the effect of ecological shocks of pest and weed invasion on children’s school attendance and working hours on the farm using the seventh round of the Ghana Living Standards Survey (GLSS). We employ a multi nomial endogenous switching regression (MESR) model that corrects for selection bias and endogeneity origi nating from both observed and unobserved heterogeneity. The results show that double shocks (pests and weeds) reduced the number of children attending school by 11% and increased children’s on-farm working hours by 0.75 h. Comparatively, the decline in the number of children attending school due to weed invasion (0.88) is higher than the decline due to pest invasion (0.43). Furthermore, weed invasion increases children’s on-farm working hours by 0.05 h while pest invasion reduces children’s on-farm working hours by 0.08 h. Increasing access to improved agricultural technologies bundled with credit and policies are critical to reducing the threats from ecological shocks and improving farmers’ welfare. To avert the decline in school attendance and children’s working hours requires training farmers to reduce the practice of continuous cropping and to embrace crop rotation and fallow to reduce the spread of pests and weeds.Item Non-tariff measures and household welfare: Evidence from Ghana(Journal of International Development, 2023) Martey, E.; Onumah, E.E.; Onumah, J.A.Most studies on the impacts of non-tariff measures (NTMs) economic outcomes are at the macro-level with limited micro-level studies. This study uses primary data on 604 commercial farm households in Ghana to examine the relationship between NTMs and household welfare outcomes. The results show that NTMs are positively associated with assets, household expenditure and income, but negatively associated with food expenditure, household dietary diversity score (HDDS) and poverty probability index (PPI). We find that the results are not likely to be driven by unobserved heterogeneity. Our results suggest that the Potential mechanisms through which NTMs influence welfare outcomes are household income and expenditure. The main implication of the study is that a reduction in the number of customs formalities and the cost of testing and certification can facilitate trade and contribute to the economic development of commercial farm households.Item Nontariff measures and production allocation decisions of cereal farmers in Ghana(wileyonlinelibrary.com/journal/agr, 2023) Onumah, E.E.; Martey, E.; Brümmer, B.Using exogenous variation in trade shocks, this study examines the association between nontariff measures and cereal production allocation decisions among commercial farmers in Ghana. We study nontariff measures from both an extensive (experience of nontariff measures) and an intensive (cost of nontariff measures) perspective using a sample of 455 cereal farmers in Ghana. We employ the seemingly (un)related regression (SURE) and the inverse probability weighting with regression adjustment (IPWRA) to estimate the effect of nontariff measures on production allocation decisions. The result shows that nontariff measures are associated with lower cereal production and intensity of cereal commercialization but positively associ ated with the consumption of cereals. The results are robust after controlling for potential endogeneity using the Lewbel 2SLS. In addition, we find that our results are not likely to be driven by unobserved heterogeneity. We find evidence of consistent and robust estimates of nontariff measures when the IPWRA model is applied and compared to the SURE estimates. Overall, our study shows that nontariff measures can be a depressive pathway to cereal sustainable production and commercialization with associated policy implications for economic development [EconLit Citations: F1, F13, E23, Q13].Item PICS or poly sack: Traders’ willingness to invest in storage protection technologies(Journal of Agriculture and Food Research, 2023) Martey, E.; Etwire, P.M.; Suraj, M.M.; Goldsmith, P.This study applies a simple financial model to compare the profitability of selected grain storage protection technologies (PICS and Poly sacks) in Ghana. To address the objectives, market survey data of soybean traders who represent a section of the soybean supply chain was used. Per the model, the price seasonality for profitable soybean storage was estimated by accounting for costs related to storage (protectants, maintenance, supervision, and labor), the opportunity cost of capital, and storage technologies (PICS and Poly sacks). Results indicated that the profitability associated with poly sacks was higher than the PICS bags over the entire support of seasonal harvest prices and consistent across the different trader types. Secondly, less than 20% of the traders were willing to invest in storage protection technologies since the value of their storage losses is higher than the value of the investment cost.Item PICS or poly sack: Traders’ willingness to invest in storage protection technologies(Elsevier B.V., 2023) Suraj, M.M.; Martey, E.; Etwire, P.M.; et al.ABSTRACT This study applies a simple financial model to compare the profitability of selected grain storage protection technologies (PICS and Poly sacks) in Ghana.

This study analyzed how agricultural innovations and farmer-actor interactions in the AIS contribute to poverty outcomes among agricultural households in Ghana. Data used was the Ghana socio-economic panel survey data with 891 and 2595 observations for cocoa and maize households, respectively. The multinomial endogenous treatment effect model with instrumental variables was employed for the analysis. Adopting digital technologies in combination with other innovations, and having stronger farmer-actor interactions in the innovation system were asso ciated with non-poor outcome in maize-growing households, who were poorer compared to cocoa-growing households. Innovations that consistently increased food security in both crop systems were associated with non-poor outcomes. The findings of the study highlight the need for governments and stakeholders to prioritize agricultural digitalization, encourage the adoption of multiple innovations and focus on food security-improving interventions as strategies to addressing rural poverty reduction.
