A discrete choice model with endogenous attribute attendance

This paper develops a discrete choice model in which the decision to consider an attribute in the choice process is modelled endogenously. In an application to patients' choice of general practitioner it is found that the proposed model outperforms the standard logit model in terms of goodness of fit and produces substantially different estimates of willingness to pay.
