Estimating the Demand for Calories in India
利用印度1961-1992年的总量数据，研究人均卡路里摄入与人均收入及食品价格的长期关系，发现收入弹性为0.34，而食品价格弹性不显著，表明经济增长显著改善了卡路里摄入，但食品补贴效果有限。
Abstract This article examines the long‐run relationship between per capita calorie intake, per capita income, and food prices using aggregate data for India, 1961–1992. Cointegration analysis yields an income elasticity of calorie intake of 0.34, while the food‐price elasticity is insignificant. Thus, economic growth in India, as measured by increasing per capita income, has significantly improved calorie intake; future income growth can alleviate further inadequate nutrition. However, significant improvements in calorie intake cannot be made directly by food subsidies. A further result is that calorie intake is Granger‐caused by income and not vice versa: income generation is unconstrained by calorie intake.
