Description
Summary:This study investigates the impact of improved maize varieties and inorganic fertilizer on productivity and consumption expenditure of smallholder farmers in Eastern Ethiopia. The study uses primary data of maize farmers and a multinomial endogenous switching regression model to account for selection bias. The findings show that combining the two technologies boosts maize yield and consumption expenditure significantly than adopting the technologies in isolation. As a result, policies targeted at improving farm household welfare and productivity should promote the adoption of a combination of agricultural technologies rather than a single technology.
