The literature on vertical integration in markets with regulated upstream prices suggests that the integrated upstream firm might engage in non-price discrimination. Several studies provide policy recommendations derived either from case study approaches or based on theoretical modeling which...

We examine the bidding behavior of firms competing on ERCOT, the hourly electricity balancing market in Texas. We characterize an equilibrium model of bidding into this uniform-price divisible-good auction market. Using detailed firm-level data on bids and marginal costs of generation, we find...

Although much work has been done analysing the possible causes of the New Zealand-Australian income gap, to date there has been little analysis of the extent to which this gap differs by gender and age. Using New Zealand and Australian employment and census data we examine these differences and...

Estimating market power is often complicated by the lack of reliable measures of marginal cost. Instead, policy-makers often rely on other summary statistics of the market, thought to be correlated with price cost margins---such as concentration ratios or the HHI. In many industries, these...

The paper examines the economic and regulatory factors that led to an explosion in the wholesale power prices, supply shortages, and utility insolvencies in California’s electricity sector. A necessary first step in determining the lessons learned from the California electricity crisis is a...

“Network neutrality” and “open access” are two policies designed to preserve openness on the Internet. Open access mandates openness of conduits (e.g. television cable and DSL) to service providers (e.g. America Online), while network neutrality mandates openness to advanced content...

This paper examines problems of entry, exit and competition in Ukrainian product markets. It finds that Ukraine still has too little of all three, and that exit mechanisms, in particular, function poorly. Since impediments to entry and exit are largely the product of excessive and ill...

Broadband “open access” regulation mandates openness of conduits (e.g. upgraded cable television) to service providers (e.g. America Online), but policy discussion often suggests that the ultimate goal is openness to advanced content (streaming video, interactive e-commerce, etc.). We define...

Ein Jahr nach Inkrafttreten der deutschen Energierechtsnovelle sind die Konturen der zukünftigen Strommarktregulierung noch zu weiten Teilen ungeklärt. Vor diesem aktuellen wirtschaftspolitischem Hintergrund wird in diesem Papier die Frage nach einer sachgerechten Ausrichtung der...
