Comments on “ Alternative models of demand for automobiles ” by Charlotte Wojcik

چکیده
In a recent paper in this journal, Wojcik (2000) argues that the nested logit model “is likely to be superior” to alternative random coefficients logit specifications, like those we and many others have used in recent work (e.g. Berry, Levinsohn, and Pakes (1995), henceforth BLP). Her conclusion is based on a within sample “prediction” exercise. We would like to raise several issues about her conclusion.

This paper uses data on automobile purchases to compare two alternatives to the multinomial logit model. The results indicate that the nested logit model is likely to be superior to the more general Berry–Levinsohn–Pakes model for applications using aggregate-level data. 2000 Elsevier Science S.A.
