Did BSE affect demand for beef in Canada? An Application of the Quadratic Almost Ideal Demand System∗
نویسنده
چکیده
A quarterly, weakly-separable, Quadratic, Almost Ideal Demand System is estimated for beef, pork and chicken in Canada. The restrictions that would lead to the less flexible AIDS model were rejected at the five per cent level. Results for the first stage model indicated that demand for the meat group is inelastic, with an own-price elasticity of -0.24. Demand for beef in Canada was inelastic during the period under study. The conditional, uncompensated own-price elasticity of demand was -0.83, while the unconditional, uncompensated elasticity of demand for beef was -0.43. Demand for beef in Canada appeared to become more inelastic prior to discovery of BSE in Canada, but since then beef demand has become less inelastic, although the change is subtle.
