The impact of informal credit on rural agricultural productivity in the savannah ecological zone of Ghana

Purpose The purpose of this paper is to examine the impact of informal credit access on agricultural productivity in rural Ghana. Design/methodology/approach Data sets from the Ghana Feed the Future baseline survey involving a total sample of 2,437 rural farm households were used. In order to address the problem of endogeneity and sample selectivity bias, the endogenous switching regression (ESR) model was employed to examine whether rural farm households' with access to informal credit and those without access differ in terms of their productivity levels and whether access to informal credit affects agricultural productivity. Findings Estimates from the ESR show that access to informal credit significantly promotes agricultural productivity. Specifically, farmers with access to informal credit were able to achieve a yield of 48.42 kg/ha more than their counterparts without informal credit access. In terms of the counterfactual, farmers without informal credit access would have increased their yield by 57.61 kg/ha if they were to have access to informal credit. Research limitations/implications - The study was restricted to the savannah ecological zone of Ghana. This limits the extent of generalisation of results. Originality/value This study provides a rigorous econometric analysis of the impacts of access to informal credit on agricultural productivity in rural Ghana. The study contributes to the current debate on the link between access to informal credit and agricultural productivity and provides valuable input for policymakers.
