ENERGY INTENSITY IMPROVEMENTS IN STEEL MINIMILLS

Over the past 20 years, U.S. steel manufacturing has experienced an episode of creative destruction. Iron-ore based plants closed, and new electric arc furnace (EAF) plants–the "minimills"–opened. The steel industry is an energy intensive segment of manufacturing, and the changeover causes major change in energy use. The analysis here links a plant-level database from the Bureau of the Census with publicly available sources and obtains measures of the best practice energy use in minimills. The analysis examines how technical efficiency, vintage, and capacity utilization affect plant-level electricity use per ton of steel. This measure of electricity use gives a plant's "energy intensity." Plants in the sample keep operating even during deep recessions, suggesting that energy, e.g., BTU, taxes may fall short of the fullest potential for reducing energy use. During recession, plants actually may continue to operate at lower output rates and higher energy intensities rather than close down. Substantial potential exists for energy improvements of as much as 1 billion kWh per year. New facilities exhibit energy intensity improvement of 6.2 kWh/ton per year. This finding is consistent with engineering estimates. Realizing this potential among all plants would require policies that assist capital turnover.     

CERCLA AND DEEP POCKETS: MARKET RESPONSE TO THE SUPERFUND PROGRAM

This paper uses event study methods to estimate wealth effects upon shareholders who are named by the U.S. Environmental Protection Agency (EPA) as potentially responsible parties at a Superfund site. Impacts appear to be divided into three periods: an initial program period where stock market effects depend largely on prior visibility of the site, a second period where likely financial impact is more important, and a third period where notification has little association with either visibility or financial measures. However, the expected remediation cost burden is not borne evenly. "Deep-pocket" firms appear to be disproportionately penalized by the market during the second period.     

Beyond Stratification: The Emerging Class Structure in Rural Russia

Using survey data from Russian villages, this article examines the development of a rural class structure in postcommunist Russia. It is argued that as a result of market reforms, social and economic relations have evolved beyond stratification, and that, rather, a rural class structure is emerging. Five measures of an emerging class structure are posited: income stratification, land holdings, capital stock, class consciousness, and shared attitudes and values. Focusing on upper and lower income strata, significant differences are documented for each measure. The economic and political implications of the findings are discussed.     

Lancashire,India, and shifting competitive advantage in cotton textiles, 1700–1850: the neglected role of factor prices1

In the early eighteenth century, wages in Britain were more than four times as high as in India, the world's major exporter of cotton textiles. This induced the adoption of more capital‐intensive production methods in Britain and a faster rate of technological progress, so that competitive advantage had begun to shift in Britain's favour by the late eighteenth century. However, the completion of the process was delayed until after the Napoleonic Wars by increasing raw cotton costs, before supply adjusted to the major increase in demand for inputs.     

Expectations Models of Asset Prices: A Survey of Theory

This paper identifies restrictions on preferences under which various classes of “expectations” theories of asset prices—i.e., uncertainty models of asset prices which coincide with the corresponding certainty theory except that expected future prices replace actual future prices—are valid. Major classes of expectations models surveyed are martingale models, the expectations hypothesis of the term structure of interest rates, and models of exhaustible resources and futures markets. In each case the required restriction is related to the assumptiono f risk—neutrality, but the precise nature of the required restriction is shown to differ significantly among the various classes of expectations theories.
