| Government price policy in Pakistan affects both the supply and demand of wheat. The wheat market has been established in a particular idiosyncratic manner in Pakistan, and a thorough appraisal of policy needs to take this into account. Hence, to analyse various policy interventions, this study develops a multi-level wheat market model. After considering the real world aspects of the wheat marketing chain, a conceptual framework is developed involving five market levels. This is then translated into a multi-equation econometric model. The model is based on secondary time series data from 1971 to 1996. It consists of equations representing supply, demand, stock holding, importing and price formation. The model is used to estimate changes in consumer... |

| The paper describes a study of canal and supplemental ground water used by 544 farmers for wheat crop in the Rechna Doab catchment of Pakistan. The main objective was to assess the on-farm financial gains through conjunctive water use. For econometric analysis, a linear relationship between the wheat production and different determinant variables was assumed. The results highlighted the problem of increased use of tubewells water in the saline zones that had resulted in the deterioration of the groundwater quality and led to the problem of permanent upconing of saline groundwater. Conjunctive water management increased the farm income by about Rs. 1000 and 5000 per hectare compared to only using the canal and tubewell water, respectively The results of... |
