Özet (Çeviri)
Aggregation methods for making aggregate predictions from disaggregate pure discrete choice models have previously been developed and analyzed by numerous atliors. This dissertation first introduces two more methods which are some variations of one of the existing methods. The dissertation then modifies these methods to incorporate heterogeneity of choice sets. The resulting adjusted methods are shown to produce more accurate predictions. After this modification, the dissertation extends the aggregation methods to mixed continuous/discrete choice models where the choice sets of individuals consist of both discrete and continuous alternatives. Once aggregation methods are defined for such models, the focus of the analysis is the comparison of the aggregation methods in terms of their accuracy. Following a section on theoretical comparisons, some em- pineal results which are obtained from a multinomial mixed/continuous transportation demand model are presented to provide some evidence as to the relative performance of the methods.Related to the aggregation problem is the measurement of aggregate welfare change of consumers when evaluating alternative policies based on models *vhere agents are assumed to face discrete and/or continuous choices. The final section of the dissertation first develops a measure of welfare change for evaluating the welfare change of a single profit maximizing firm whose behavior is modeled within a mixed continuous/discrete choice framework. Then, it is shown that the aggregation methods analyzed in the previous sections can be applied to measuring aggregate welfare change as well. An empirical example, which deals with measuring the welfare change due to elimination of some alternatives; completes the dissertation.
