Adult Equivalent Scales: An Alternative Approach

Abstract

Adult equivalent scales were estimated for five food groups and total food consumed at home. The scales were specified as continuous functions of age and restrictions were placedon the scales so that they approximate the way an individual affects household food expenditures throughout his life. The scale function is easily incorporated into expenditure models, and statistical tests can be used to determine the importance of household composition in explaining household expenditure behavior. Children were found to consume less total food-beef, pork, and vegetables-than adults, while the middleaged spent less on fruit than the elderly.

Review Faktor Determinan Keragaman Konsumsi Pangan

“…Preferensi pangan pada anak-anak berbeda dengan kelompok orang dewasa dan kelompok usia lanjut (Buse & Salathe 1978). Konsumsi pangan pada kelompok anak-anak umumnya bergantung dari apa yang diberikan oleh ibu atau orangtuanya (Abraham 1988;Blanciforti et al 1981;Horton 1985;Buse & Salathe 1978) yang tentunya berbeda dengan yang diberikan untuk kelompok remaja atau dewasa.…”

Kelompok remaja dan dewasa lebih suka untuk memilih pangan yang dikonsumsinya sendiri dan pada kelompok remaja biasanya kurang begitu peduli dengan kandungan gizi yang tinggi pada pangan dan mereka cenderung lebih menyukai pangan yang sedang populer (Blanciforti et al 1981;Rappoport et al 1992;Kelly 1981;Woodward 1985).…”

Food Price Volatility and Its Implications for Food Security and Policy

“…23 An alternative approach to account for such differences employs equivalency scales that take into account nutritional requirements based on age and, sometimes, gender when calculating per capita measures. For an early example, see Buse and Salathe (1978). 24 It is often assumed the poorer households smooth consumption in the face of shocks; however, using a poverty trap model, Carter and Lybbert (2012) show that below a critical wealth level, poorer households smooth (or protect) assets rather than consumption due to high marginal values of assets and the potential of future-negative shocks.…”

“…See, for an early example, Buse and Salathe (1978). An advantage of including household composition in the specification, rather than using equivalence scales, is that this method allows the data to specify the parameterization of the scales.…”
