The alternative minimum tax (AMT) is reaching a broader segment of individuals. Yet, many of these taxpayers are not aware of the implications of this tax. Even worse, some of their tax advisors are not as informed as they should be. By identifying items that trigger the individual AMT,...

When agents make their choices simultaneously, network effects often give rise to a selection problem involving perfectly coordinated, Pareto-optimal equilibria. We characterize this selection problem, and introduce a generalized sequential choice model to address it. In this model, we show how...

Can indirect network effects lead to adoption externalities? If so, when? We show that in markets where consumption benefits arise from hardware/software systems, adoption externalities will occur when there are (i) increasing returns to scale in the production of software, (ii) free entry in...

The conventional wisdom is that indirect network effects, unlike direct network effects, do not give rise to externalities. In this Paper we show that under very general conditions, indirect network effects lead to adoption externalities. In particular we show that in markets where consumption...
