Technical Efficiency and Its Determinants on Thailand’s Rice Production

This study employs the time-varying stochastic frontier production function in order to analyze technical efficiency of rice production in Thailand and its determinants. The unbalance panel data of rice production between 1987/88 and 2007/08 crop years were employed. The result indicated that the technical efficiency is decreasing from 88.32% in 1987/88 crop year to 72.63% in 2007/08 crop year. This reflects that the farmers in 1987/88 crop year used their available resources more effectively than the farmers in 2007/08 crop year. The factors affecting technical efficiency are the ratio of hired labor and machinery use, access to farm credit, farm income and farm size. To improve technical efficiency at the farm level, the study suggests that followings: (1) establishing farmer organized networks for creating an economy of scale in acquiring some inputs; (2) a promotion of alternating green manure crop in rice cropping system would enhance a soil quality management and (3) providing supervised credit in the form of technical assistance and farmer capacity built up is necessary.
