This paper examines vertical arrangements in electricity markets. Vertically integrated wholesalers, or those with long-term contracts, have less incentive to raise wholesale prices when retail prices are determined beforehand. For three restructured markets, we simulate prices that define...

We prove that, for general demand and cost conditions and market structures, the fraction of first-best surplus that a monopolist is unable to extract in a market provides a tight upper bound on the relative distortions arising from firms' equilibrium decisions at all margins (entry and...

This paper argues that the market rules governing the operation of the England and Wales electricity market in combination with the structure of this market presents the two major generators National Power and PowerGen with opportunities to earn revenues substantially in excess of their costs of...

We analyze entry, pricing and product design in a model with differentiated products. Under plausible conditions, entry into an initially monopolized market leads to higher prices for some, possibly all, consumers. Entry can induce a misallocation of goods to consumers, segment the market in a...

We examine the relationship between market structure and the persistence of U.S. dollar-based sectoral real exchange rates for fourteen OECD countries. Our empirical results based on disaggregated data suggest that differences in market structure significantly determine the rates at which...

Industry cost and demand conditions can vary across countries leading to differences in industry market structure, including the distribution of output and productivity across firms and the magnitude of entry and exit flows. It has been argued that despite many outward similarities, two of the...

The relevance of imperfect competition for models of aggregate economic fluctuations has received increased attention from researchers in both macroeconomics and industrial organization. Measuring properly the size of industry markups of price over marginal cost is important both for assessing...

This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

This paper examines the relationship between the structure of banking markets and economic growth using a new dataset on manufacturing industry-level growth rates and banking market concentration for U.S. states during 1899-1929--a period when the manufacturing sector was expanding rapidly and...

We document the behavior of trade prices during the Great Trade Collapse of 2008-2009 using transaction-level data from the U.S. Bureau of Labor Statistics. First, we find that differentiated manufactures exhibited marked stability in their trade prices during the large decline in their trade...
