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.
