We analyze the welfare effects of parity rules, prevalent in telecommunications and other regulated industries, that force a vertically-integrated input monopolist to treat its own downstream affiliate and downstream competitors comparably in terms of input price and quality. When input pricing...

This paper examines the tension between competition for the customer and competition in the market in a differentiated-product oligopoly. Consumers make purchases through an exclusive supply relationship that is modeled as a discrete-continuous choice problem. We characterize Bertrand-Nash...

We analyze the welfare effects of “parity” rules that force a vertically-integrated input monopolist (VIM) to treat downstream affiliates and competitors alike in terms of price and quality. We find that input-quality parity can lower social welfare when input pricing is unregulated. In...

We examine the impact on inter-regional trade in eastern U.S. electricity markets arising from the FERC-supported creation of Independent System Operators (ISOs). Our analysis focuses on the PJM ISO (Pennsylvania, New Jersey, Maryland, and other states) and its trade with the New York ISO and...

We investigate the impact of creating Independent System Operators (ISOs) to independently manage regional electricity transmission resources and institute regional electricity exchange markets. Our analysis examines how the formation of the PJM Independent System Operator (ISO) in Pennsylvania,...

This paper compares one-part pricing and two types of two-part pricing in a general discrete-continuous choice model, providing more extensive welfare results than prior literature. Under two-part pricing, firms may set fixed fees with or without unit-price commitment. When unit-price commitment...

In electricity and other industries, it is increasingly common for a utility's upstream affiliate (i.e., an electric generation supplier) to be unregulated while its downstream affiliate (i.e., the local distribution company offering retail service) is subject to regulation. In these industries,...

We investigate the competitive effects of exchanges or sales of airport landing slots. In our model, airlines with potentially asymmetric slot allocations must decide upon which routes to use their landing slots. When all airlines serve the same routes in a slot-constrained Cournot Nash...
