Investigating the Quantitative Effect of Trade Liberation on Export Supply of Agriculture Sector: Export of Fruit and Its Dried Products in Iran

This paper deals with the effects of trade liberation policy regarding agriculture sector. to this end, the quantitative effects of coherence, structural-technical obstacles, the consumption gap of domestic demand, exchange price and the relative prices of the export supply of fruit and its died products in iran during 1963-2001 have been investigated. the significance of the cointegration of variables and the results of the estimation of the parameters of the model, using minimum squares method show that: firstly, there is a difference between the short and long run ties of export in this sector. secondly, assuming constant conditions, the short and long run price elasticity of export supply of fruit and its dried products is trivial and les than unity. therefore, liberating the foreign trade of this sector will not maintain its share in the world market. thirdly, the effect of coherence, structural-technical obstacles, as well as those related to technology and legality, and the variable of consumption demand gap are more serious compared to relative prices. fourthly, the oil shock of the 60s has brought about significant positive differences between the short and long run ties of the export supply model of these products
