This study analyzes the economic efficiency of rice farms incorporating the rice income direct payment program as a constraint and examines how factors such as producer characteristics, scale, specialization, producing and asset features affect the efficiency. We use a mathematical optimization model with the capital constraint, output price risk, and the program. The empirical results show that the bias in the efficiency measurement from omitting the policy effect is substaintial.
