| dc.description.abstract | Energy and protein malnutrition has been a persistent problem in the Philippines. According to the 1998 National Nutrition Survey, it was found that among the nutrients, Filipinos in general only meet the corresponding RDA for proteinĀ· at 106%. Energy was only 87.8% of RDA, while the intake of vitamins and minerals remained grossly inadequate, ranging from 57.1% to 88.1% of RDA. This paper aims to determine the effect of changes in income and food prices on the consumption behavior of Metro Manila residents. Also, the effect of price changes on their nutritional intake is determined by estimating the sensitivity of their nutrient intake to changes in prices, specifically calorie and protein intake. Using the raw data from the 1999- 2000 Food Consumption Survey conducted by the Bureau of Agricultural Statistics (BAS), the demand function of the 13 most commonly consumed food items is estimated using the tobit stochastic model. Then the demand elasticities and nutrient price elasticities of these food items are calculated. Among the 13 food items, only 8 (rice, instant noodles, beef, chicken, egg, tomato, mango and milkfish) are regressed by EViews, the statistical software used due to the technical or illegal processes. The resulting income elasticities indicate that all sources of protein (meat), with the exception of egg, are luxury items while all sources of carbohydrates are found to be normal goods. This is despite the findings of FNRI that Filipinos are able to meet the required protein intake while having deficiencies in the required intake of carbohydrates. This ability to meet protein requirements can be attributed to the fact that carbohydrate sources, like rice, also have high protein content. The demand for almost all food items are found to be sensitive to changes in income among lower socioeconomic classes. This findings support the view of the World Bank (1981) that the most efficient policy to increase the calorie and protein consumption is to raise the income of the poor. The demand for these food items and nutrients, on the other hand, are insensitive to changes in price. Most of these items have nutrient-price elasticities within the range of -0.01 to -0.02. Because of these findings, price stabilization of these food items is not the answer to combat energy and protein malnutrition. Rather, it promotes the findings of several economists such as Haddad (2003), who stated that investment in education and sanitation is most important to improve nutrition in the long run. | |
