Effectiveness Analysis of Agricultural Protection Policy on Food Supply, Export and Farmer-Welfare in Nigeria: Generalized Method of Moment Approach

Abstract

This study examined the effectiveness of agricultural protection policy and other macroeconomic variables on food supply, agricultural export, and farmers welfare in Nigeria, from 1980-2016 with a special interest in their relationship with the political economy. The specific objectives were to (i) estimate the degrees of agricultural protection, domestic agricultural food supply and economic welfare to farmers in Nigeria, (ii) determine the effectiveness of agricultural protection on food self-supply, agricultural export; and farmer-welfare. Data were obtained from secondary sources. Descriptive statistics and generalized method of moment (GMM) were used. Nigeria’s self-food supply was slightly above 50% while the rest of the consumption depended on importation. The welfare measure to farmers was relatively poor and not good enough to motivate them. There was a positive and significant relationship between export and agricultural protection. A significant and positive relationship also exists between farmer-welfare and protection in the sector.
