Effects of Manufacturing Exports and Human Capital on Total Factor Productivity and Economic Growth in OIC Countries

in this investigation, first the equation of food demand was estimated using an almost ideal demand system (AIDS) and the Iranian cross sectional survey of income expenditure in 2005. Because of the cross sectional form of the data, the prices were calculated as marginal or unit values. Then by applying the elasticities of food categories, nutrient elasticities were extracted using Lancaster technology of consumption. These elasticities are useful to the analysis of the effects of aid policy on food demand and nutrient consumption respectively, and show the effects of the change in one food category7 price or food expenditure on the availability of each nutrient. In this article, as demand equation is blocked-recursive simultaneous system and zero value is a dependent variable, we use seemingly unrelated regressions (SUR) and Tobit model. In another section, effects on demographic variables on food prices are examined. These variables are age, education, region, urban or rural and Percapita income. Results have shown that more food expenditure causes more food quality or food consumption and education, household size and other demographic variables are often effective on the quality of food.
