In German electricity submarkets for residential customers standard contracts offered by former monopolists are the more costly option for customers who have not switched to an alternative contract yet. As most German households are served with this contract type we follow the Limit Pricing...

This paper addresses the issue of investment in electricity generation in the context of a liberalised market. We use the main results derived from a theoretical model where firms invest strategically to simulate the Spanish electricity system with real-world data. Our results indicate that,...

We try to better understand the comparative advantages of structural and behavioral remedies of deregulation in electricity markets, an eminent policy issue for which the experimental evidence is scant and problematic. Specifically, we investigate theoretically and experimentally the effects on...

This paper introduces strategic behavior of the electricity network operator in a congested network with imperfect competition for generation. It models a two stage Stackelberg game. First, the network operator sets transmission prices, then generators set output and sales. Several scenarios for...

In markets with significant scale economies and network effects, scholars and policymakers often tout open access and interoperability requirements as superior to both regulated monopoly and the break-up of dominant firms. In theory, by compelling firms to coordinate to develop common...

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...

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...

This paper evaluates the recent literature claiming that the US economy has generally become less competitive causing the US economy to perform poorly and that lax antitrust policy is one important reason for the decline in economic performance. Although there certainly are empirical facts...

This paper identifies substantial flaws in how U.S. government agencies and courts assess the impact of proposed mergers by firms using broadband networks to reach consumers. Based on current market definitions, consumer impact assessments and economic doctrine, antitrust enforcement agencies...
