Did BSE affect demand for beef in Canada? An Application of the Quadratic Almost Ideal Demand System∗

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 du...

Accounting for Trends in the Almost Ideal Demand System

Flexible functional forms of indirect utility and expenditure functions are frequently used in approximating the behavior of utility maximizing consumers to arrive at demand systems that can be easily estimated. A common nding in time series estimations of the Almost Ideal Demand System is strong persistence in the estimated residuals. This paper suggests two explanations for this result. First...
