The economic consequences of price support policies in semi-subsistence economies

Semi-subsistence households in developing countries play a considerable role as both producers and consumers of agricultural products, with a substantial part of their consumption contributed by home production for home consumption (HPHC). This study employs a modeling framework that integrates an HPHC augmented database with a modified economywide model that accommodates the distinct features of these households. Results from model simulations with border price shocks and several policy responses indicate that farm households are less influenced by external price shocks but are more responsive to enhancements in the local marketing system. Subsidies to strategic non-food imports during soaring prices appear less effective in inducing agents to engage in production. This finding suggests that the welfare gains reported by studies on price incentives locally, and agricultural policy reforms in developed market economies are likely to be large overestimates of the welfare implications for semi-subsistence households in many of the least developed economies.
