In this Perspective, I review arguments that broadband providers may be anticompetitively imposing usage-based pricing to protect their profits from “core” services (e.g., voice, video, texting) against the proliferation of “over the top” services and, as such, new price regulation of...

This paper analyzes e fficient pricing at a congested airport dominated by a single firm. Unlike much of the previous literature, we combine a dynamic (bottleneck) model of congestion and a vertical structure model that explicitly considers the role of airlines and passengers. We show that when...

In this article I analyze the effects of a recent reform intended to decrease switching costs in the cellular industry. The reform, implemented in Chile in 2012, allowed cell phone users to switch operators without any contract restriction while keeping their wireless number. Its aim was the...

We consider a profit-maximizing monopolist that faces N2 different markets while the number k of discriminatory prices is chosen by the regulator. Unlike the classical approach in which only the polar cases are considered, we explicitly analyze the case in which k is an integer between 1 and N....

The standard partial equilibrium formula for pass-through substantially mismeasures incidence in the presence of demand or supply interdependencies. We study general equilibrium tax incidence in a perfectly competitive, multiproduct setting. If only one product is taxed, the general equilibrium...

In recent years the scope for near perfect price discrimination, particularly in the digital economy, appears to have grown. This raises a question over how those jurisdictions in which exploitative price discrimination is an offence will respond. In contrast, the risk of price discrimination...

This paper develops a model to investigate the effects of spatial pricing on ride-sourcing markets. The model is built upon a discrete time geometric matching framework that matches customers with drivers nearby. We demonstrate that a customer may be matched to a distant vehicle when demand...
