Demand for Beef and Chicken Products: Separability and Structural Change

Abstract

Dynamic almost ideal demand systems are estimated for meat aggregates and for disaggregated meat products. Tests for weak separability show that consumers choose among meat products rather than meat aggregates such as “beef” or “chicken.” Therefore, tests for structural change in the meat aggregates may be biased. Tests for structural change in the meat products show an exogenous constant annual 6.4% growth in chicken parts demand from 1965 to 1985 and a 3.5% decline in beef table cut demand after 1974. Increased demand for convenience may explain these changes.

Market Demand Elasticity and Income Inequality

“…4 See also Eales and Unnevehr [11] for estimates of demand systems for meat products. 5 We thank an anonymous referee for drawing our attention to this reference and to the almost ideal demand system [10] discussed in Example 3.…”

Estimating Structural Change with Smooth Transition Regressions: An Application to Meat Demand

“…Examples pertaining especially to meat demand in the U.S. and elsewhere include Chavas (1983), Dahlgran (1987), Eales and Unnevehr (1988) Moschini and Mielke (1989), Alston and Chal-fant (1991), and more recently, Davis (1997) and Bryant and Davis (2008). Work in a similar spirit has been done in the context of the demand for fats and oils by Goodwin et al (2003) and in factor demand equations for U.S. food and kindred products manufacturing sector by Goodwin and Brester (1995).…”

Consumption Pattern of Fish in Uttar Pradesh, India

“…For multistage framework, separability assumption was necessary. It required that the marginal utilities derived from the fish consumption should be independent of marginal utilities derived from other food commodities (Eales and Unnevehr 1988, Jorgenson et al, 1988, Yen and Roe 1989, Michalek and Keyzer 1992.…”
