“…In most studies addressing beef demand, beef is considered an undifferentiated commodity (Hahn, 1988; Alston and Chalfant, 1993; Brester and Wohlgenant, 1993; Eales and Unnevehr, 1993; Kesavan et al, 1993; Eales, 1994; Eales and Unnevehr, 1994; Hahn, 1994). In addition, a number of studies recognize that, in reality, beef quality varies greatly (Eales and Unnevehr, 1988; Heien and Pompelli, 1988; Brester and Wohlgenant, 1991; Capps et al, 1994; Huang and Hahn, 1995). Among these studies, some divide beef into basically two or more categories, especially hamburger and other cuts of beef (Huang, 1985; Eales and Unnevehr, 1988; Brester and Wohlgenant, 1991; and Huang and Hahn, 1995).…”
