Before 1978, most of the U.S. domestic copper production and an important fraction of the imports were traded at a price set by the major U.S. producers. Simultaneously, the rest of the world was trading copper at prices determined in auction markets. This two-price system ended in 1978, when...

Market power on each side of a multisided platform, whether in the form of increasing prices or decreasing quality, is constrained by the risk of losing sales on the other sides. That tends to weaken market power on each side and encourages platforms to keep prices lower and quality higher than...

The issue of how to allocate pollution permits is critical for the political sustainability of any cap-and-trade system. Under the objective of offsetting firms' losses resulting from the environmental regulation, we argue that the criteria for allocating free allowances must account for the...

This article finds that the introduction of a carbon tax increased short-run carbon emissions in an imperfectly competitive wholesale electricity market. The unique feature of the Western Australian setting is that the same carbon tax was introduced and later repealed, but the market structure...

Television is the dominant entertainment medium for hundreds of millions. This chapter surveys the economic forces that determine the production and consumption of this content. It presents recent trends in television and online video markets, both in the US and internationally, and describes...

This paper develops a theory of oligopoly and markups in general equilibrium. Firms compete in a network of product market rivalries that emerges endogenously out of the characteristics of the products and services they supply. My model embeds a novel, highly tractable and scalable demand system...

Increasing competition and reducing market power are core interests of economists, regulators and the public to maximise aggregate social welfare. Low prices are achieved through intense competition in the retail gasoline market. The absence of fierce competition is referred to as market power....

We discuss the benefits of net neutrality regulation in the context of a two-sided market model in which platforms sell Internet access services to consumers and may set fees to content and applications providers on the other side of the Internet. When access is monopolized, we find that...

This paper studies an industry in which firms can choose to provide open or closed platforms. Open platforms, as opposed to closed, are extendable so third-party producers can develop extensions for them. Building on a two-sided market model, I show that firms might prefer to commit to keeping...

We compare four approaches to network neutrality and network management regulation in a two-sided market model: (i) no variations in Quality of Service and no price discrimination; (ii) variations in Quality of Service but no price discrimination; (iii) variations in Quality of Service and price...
