....way of proceeding. Estimation in both models can follow BLP. This involves solving for the values of # that predict market shares exactly. There is a very easy algorithm for doing this in the random coe#cients case, whereas there is an analytic formula for it in the nested logit. As shown in Berry (1994), the analytic form for # in the nested logit model can be used to generate a linear estimating equation for that model. Since we will need that form below we repeat it here as ln(s j ) ln(s 0 ) x j # # p p j (1 # g )ln( s j s r ) # j , 5) where s r # # r d j,r s j , ....
....j (1 # g )ln( s j s r ) # j , 5) where s r # # r d j,r s j , is the total share of the r th group. Note that the disturbance term is the value of the unobserved characteristic for product j. These # j will be correlated with ln( s j sr ) by construction, and as stressed in Berry (1994) and in BLP, regardless of the form of the demand function we expect the # j to be correlated with price in almost any reasonable model of price formation. 3 Prediction Exercises In addition to relying on a set of primitive assumptions and estimates, any prediction excercise must be clear about ....
