In this paper, we develop a panel data negative binomial count model that corrects for endogenous stratification and truncation. We also incorporate a latent class structure into our panel specification, which assumes that the observations are drawn from a finite number of segments, where the...

In this article the concept of multiproduct cost economies is modified to the case of production at vertically related stages to derive an explicit and general measure of economies of vertical integration. The utility of this measure is then demonstrated ...

Using multiple choice tasks per respondent in discrete choice experiment studies increases the amount of available information. However, respondents’ learning and fatigue may lead to changes in observed utility function preference (taste) parameters, as well as the variance in its error term...
