Distributional Effects of Technological Progress in Iranian Agriculture Sector: A General Equilibrium Analysis

Green revlution have uneven implications for income distribution, which is due to growth of agricultural land productivity. There is the possibility that new technologies contribute to unfavorable income distribution, since irrigation systems are typically large and costly projects, The shorter the time of implementation of this projects, the greater is the distributional expasition. Since 1980 for the expasition of exogenons shocks, general equilibrium theory at micro level have been developed for relative productivity of sector specific factors in two farming systems (irrigated and unimated) and, also, the specificity of land has been studied in a number of general equilibrium models, In this paper, distributional effects of technical progress in agricultural sector are discussed in a small open economy framwork. The results show that in an unbalanced growth model, for two systems of farming, i.e irrigated and unirrigeted systems, neutral technical changes. Labor saving - capital using technology (Chemical technology), have favorable effects on the labor force and small scale capital. Biotechnology - chemical technology has the greatest effect on income distribution.
