We examine welfare effects of real-time pricing in electricity markets. Before stochastic energy demand is known, competitive retailers contract with final consumers who exogenously do not have real-time meters. After demand is realized, two electricity generators compete in a uniform price...

This paper studies how competition and vertical structure jointly determine generating capacities, retail prices, and welfare in the electricity industry. Analyzing a model in which demand is uncertain and retailers must commit to retail prices before they buy electricity in the wholesale...

The so-called excess-entry theorem (Mankiw and Whinston 1986, Suzumura and Kiyono, 1987) establishes conditions guaranteeing that more firms enter a homogeneous Cournotoligopoly in equilibrium than a benevolent government prefers. We generalise the approach and analyse the behaviour of a...

The internet giants - Facebook, Amazon, Netflix and Google, among others - have transformed society with both positive and negative effects. The negative effects have been stark. There have been huge disruptions caused by e-commerce. More recently, subtler, but even more serious negative effects...

We here want to analyze how the imperfect competition mark-up and pass-through are transmitted through the production chain and how they change, as a function of the number of firms existing at each production stage. In order to have an analytical closed form solution, we use the standard linear...

One important concern for the upcoming and highly-complex voluntary incentive auctions for broadcast television spectrum is the degree to which the largest mobile wireless providers will be allowed to participate. Recently, the U.S. Department of Justice encouraged the Federal Communications...

We study sequential and single-round uniform-price auctions with affiliated values. We derive symmetric equilibrium for the auction in which k1 objects are sold in the first round and k2 in the second round, with and without revelation of the first-round winning bids. We demonstrate that...

This paper analyzes incentives of a multinational enterprise to manipulate an internal transfer price to take advantage of corporate-tax differences across countries under both monopoly and oligopoly. We examine “cost plus” and “comparable uncontrollable price” as two alternative...
