Descripción
The effect of government policies on poor people's food consumption and nutrition is determined largely by the resulting changes in incomes and prices and the response of the poor to such changes. Although responses of the poor to changes in income as measured by income elasticities of demand for food commodities have been estimated for a long time, few estimates of the responses of the poor specifically to price changes were available until the mid 1970s. During the last 10 years, however, a number of such estimates have been made using a variety of methods. the purpose has been to estimate how changes in the prices of various food commodities affect food consumption by the poor as compared with the population at large
