The Price Response of Major Crops in Pakistan: An Application of the Simultaneous Equation Model
This paper specifies a model to simultaneously estimate the price response, assuming an interdependence among crops. The model is applied to estimate own-and cross-price elasticities of five major crops in Pakistan, viz., wheat, cotton, rice, sugarcane, and maize based on the production and expected wholesale-price data for the period 1957-86. The study found little potential to enhance overall agricultural productivity by increasing the single crop price, since either the own-price elasticities were low or, otherwise, the nagative cross-price effects on the production of other crops were high. However, a 10-percent systematic improvement in terms of trade for agriculture will increase overall agricultural productivity by about 6 percent in the long run.
