Impact of improved maize varieties on food security in Eastern Zambia: A doubly robust analysis

摘要: This study investigates the impact of improved maize varieties on household food security in eastern Zambia using survey data from a sample over 800 rural households. Since treatment effect estimates are often prone to misspecification either or outcome equation, we use doubly robust inverse probability weighted regression adjustment method, complemented with propensity score matching six different measures obtain reliable estimates. Generally, find positive adoption across two econometric approaches. Maize being most important staple has great bearing status farm It is therefore imperative that conducive environment created promotes yield improving technologies.
