We correct and extend the results of Gans (2015) regarding the effects of net neutrality regulation on equilibrium outcomes in settings where a content provider sells its services to consumers for a fee. We examine both pricing and investment effects. We extend the earlier paper's result that...

We discuss network neutrality regulation of the Internet in the context of a two-sided market model. Platforms sell broadband Internet access services to residential consumers and may set fees to content and application providers on the Internet. When access is monopolized, cross-group...

The axiomatic route to the foundation of contest success functions (CSF) has proved to be both useful and prolific. The standard approach in the literature is based on the decision-theoretic notion that choice probabilities should be independent of irrelevant alternatives (Skaperdas, Economic...

Using a simple monopoly model, this note analyses the incentives of a vaccine producer. Because a vaccine tends to eradicate the disease for which it is intended, it also tends to destroy its own market. This means that monopolistic producers may be tempted, in a socially non-optimal way, to...

This paper analyses the profit maximising capacity choice of a monopolistic vaccine producer facing the uncertain event of a pandemic in a homogenous population of forward-looking individuals. For any capacity level the monopolist solves the intertemporal price discrimination problem within the...

This expository paper describes the factors that contribute to failure of health insurance markets, and the regulatory mechanisms that have been and can be used to combat these failures. Standardized contracts and creditable coverage mandates are discussed, along with premium support, enrollment...

In this paper we analyze a stochastic dynamic advertising and pricing model with isoelastic demand. The state space is discrete, time is continuous and the planing horizon is allowed to be finite or infinite. A dynamic version of the Dorfman–Steiner identity will be derived. Explicit...

In infinite horizon, a credible durable-good monopolist may resort to intertemporal price discrimination. We provide an analytical characterization of his optimal price policy when consumers and the monopolist have different values for the trade because of distinct discount factors.

We study the principal–agent problem. We show that b-convexity of the space of products, a condition which appears in a recent paper by Figalli, Kim and McCann (2011) [9], is necessary to formulate the problem as a maximization over a convex set. We then show that when the dimension m of the...

Carbon capture and storage (CCS) has been demonstrated as a viable option for reducing carbon emissions to the atmosphere. We consider a situation where a tax on emissions is imposed on carbon dioxide (CO2) producers to encourage their participation in CCS. Operators of CO2 transportation...
