We examine the incentives and implications of supplier encroachment, when final good produc-tion requires the use of multiple complementary inputs and the entry of a supplier into the final good market gives rise to mutual outsourcing of inputs between the encroaching supplier and the incumbent....

The comparison between specific (per unit) and ad valorem (percentage) taxation has been one of the oldest issues in public finance. In Cournot markets, with deterministic costs structures, onventional wisdom has it that ad valorem taxation welfare-dominates specific. The objective of this paper...

We develop a two-sided market model with an upstream-downstream structure. More specifically, the platform consists of two rival upstream firms and a downstream monopolist. Each upstream firm negotiates the input price (license fee) with the downstream monopolist and also chooses the amount of...

There are examples of entry in two-sided markets, where first entrants occupy a `central location' and serve agents with `intermediate tastes', while later entrants are niche players. Why would the first entrant choose to become a `general' platform, given that later entrants will not have...

We propose a new location model where consumers are allowed to make multiple purchases (i.e., one unit from each firm). This model fits many markets (e.g. newspapers, credit cards, scholarly journals, subscriptions to TV channels, etc.) better than existing models. A common feature of these...

"We develop an upstream-downstream model to analyze downstream firms' incentives to bundle. In our framework, the upstream firms are content providers (such as television stations) and the downstream firms are system operators (such as cable/satellite operators). We show that an a la carte...

An interesting feature of the data is that the price distribution in the absence of promotional activities first order stochastically dominates that under display or feature advertising. The theoretical model we introduce can yield an equilibrium that is consistent with the above observations.
