Abstract

In this study impacts of government intervention on supply, yield and cropping area of WHEAT was investigated using NOMINAL PROTECTION RATE. The data set applied in the study was obtained from different sources such Ministry of Statistical Yearbook and FAO website for period of 1353-1384. After testing data stationary and calculating the NOMINAL PROTECTION RATE, the impact of supporting policies was studied using ARDL approach and Nerlove model. The results of the study showed that NOMINAL PROTECTION RATE was negative during the study period, indicating that not only WHEAT producers were implicitly taxed. The negative support tends to decrease slowly during the period. WHEAT real price did not show considerable impact on WHEAT supply in the short run. While in the long run WHEAT real price, technological change and cropping area revealed a positive impact on WHEAT supply. The results also showed that while NOMINAL PROTECTION RATE had no impact on cropping area, it is affected by lagged cropping area.
