Abstract


In order to solve serious problem on the lack of job opportunity and poverty in Indonesia, oil palm expansion driven by smallholders have been taken into the economic development agenda. The evidence shows that oil palm expansion by smallholders have a great performance for improving livelihood of rural community. Thus, this study aims to estimate the causal effect of oil palm expansion on farmers’ livelihoods in Indonesia. Using cross-sectional data from 271 households in Riau Province, the determinants of farmers’ decisions to expand oil palm farm size and the impacts of expansion are analyzed. Propensity Score Matching was employed in order to deal with self-selection biased in the evaluation of oil palm expansion impact. In the first step, logit model was applied to analyze the determinant of oil palm expansion. In the second step, each observation is matched with a similar propensity score value in order estimate the average treatment effect for the treated (ATT). Empirical results show that number of family members actively involved in oil palm cultivation, farmers’ financial assets, contract farming, and distance to the market are significantly associated with likelihood for expanding farm size. Positive and significant impacts of crop income from oil palm and per capita expenditures, confirms that oil palm expansion help reducing the problem of job opportunity and poverty in Indonesia. This study implicates that, to improve oil palm expansion practice in Indonesia, several schemes must be considered: enhancing human resources development, integrating oil palm marketing schemes, and improving infrastructure facilities.
