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.     

THE EFFECT OF REPUTATION ON THE DECISION TO JOINT VENTURE

This paper focuses on the impact that reputation has on the decision to proceed with a strategic alliance. Employing reputation constructs adapted from the Fortune Corporate Reputation Survey, we manipulated a target firm’s reputation in an experimental design. The subjects were placed in the role of CEO of the partner firm and asked whether they would engage in the alliance. Findings indicate that (1) reputation is a multidimensional construct, (2) the personal information-processing characteristics of the decision-maker mediate the reputation effect and may suppress the reputation information, (3) subjects may compensate weaker elements of reputation for stronger ones when making decisions, (4) product and management reputation are the most important factors, and (5) reputation is a factor affecting the decision regardless of whether the proposed target is a supplier or a competitor. © 1997 by John Wiley & Sons, Ltd.     

Insider Trading, News Releases, and Ownership Concentration

This paper investigates the market's reaction to U.K. insider transactions and analyzes whether the reaction depends on the firm's ownership. We present three major findings. First, differences in regulation between the U.K. and United States, in particular the speedier reporting of trades in the U.K., may explain the observed larger abnormal returns in the U.K. Second, ownership by directors and outside shareholders has an impact on the abnormal returns. Third, it is important to adjust for news released before directors' trades. In particular, trades preceded by news on mergers and acquisitions and CEO replacements contain significantly less information.     

THE STRATEGIC TIMING OF DIRECT DEMOCRACY

This paper focuses on the strategic timing of elections by agenda-setters in direct democracy settings. Because concurrent elections affect turnout, scheduling referenda for different elections will produce different median voters. I hypothesize that agenda-setters with power over the timing of a referendum will schedule the referendum in conjunction with the other set of races that produce a policy closest to their preferred outcome. Consistent with the theory, I show that Wisconsin school boards' use of special elections for school referenda are related to differences in the revealed preferences of voters in low- and high-turnout elections.     

AN EMPIRICAL ANALYSIS OF PAYMENT CARD USAGE*

I exploit a unique data set on the payment card industry to study issues associated with network effects and two‐sided markets. I show that consumers concentrate their spending on a single payment network (single‐homing), although many maintain unused cards that allow the ability to use multiple networks (multi‐homing). Further, I establish a regional correlation between consumer usage and merchant acceptance within the four major networks (Visa, Mastercard, American Express and Discover). This correlation is suggestive of the existence of a positive feedback loop between consumer usage and merchant acceptance.     

Re‐Use of Collateral in the Repo Market

This paper introduces a methodology to estimate the re‐use of collateral based on actual transaction data. With a comprehensive data set from the Swiss franc repo market we are able to provide the first systematic study on the re‐use of collateral. We find that re‐using collateral was most popular prior to the financial crisis when roughly 10% of the outstanding interbank volume was secured with re‐used collateral. Furthermore, we show that the re‐use of collateral increases with the scarcity of collateral. By giving an estimate of the collateral re‐use and explaining its drivers, the paper contributes to the on‐going debate on collateral availability.     

Asymptotics of the price oscillations of a European call option in a tree model

It is well known that the price of a European vanilla option computed in a binomial tree model converges toward the Black-Scholes price when the time step tends to zero. Moreover, it has been observed that this convergence is of order 1/ n in usual models and that it is oscillatory. In this paper, we compute this oscillatory behavior using asymptotics of Laplace integrals, giving explicitly the first terms of the asymptotics. This allows us to show that there is no asymptotic expansion in the usual sense, but that the rate of convergence is indeed of order 1/ n in the case of usual binomial models since the second term (in     ) vanishes. The next term is of type   C ₂( n )/ n   , with   C ₂( n )  some explicit bounded function of n that has no limit when n tends to infinity.     

Transnational Organizing in Agrarian Central America: Histories, Challenges, Prospects

Central America was one of the principal regions where transnational peasant organizing emerged and from which it spread in the late 1980s and early 1990s. Yet by the late 1990s the seemingly powerful transnational peasant coalitions were in disarray. Their successors have had only a modest impact since 2001. The article points to two main sources of weakness in Central America's transnational peasant coalitions: first, a variety of intra-organizational problems, including political differences, disputes over resources, over-funding by cooperation agencies, and an emphasis on networking activity, rather than concrete gains, as a measure of success; and second, an external political, economic and demographic environment that has become increasingly unfavourable. Elements of the latter include the long-term declines in maize and coffee prices, only recently reversed in 2006; the declining importance of agriculture and the imposition of a new economic model centred around industrial and financial activities; and the rapidly growing levels of out-migration and of dependence of those remaining in the countryside on family remittances and non-agricultural activities. The article concludes not with definitive arguments, but rather with a series of questions about what might constitute effective strategies for transnational peasant organizing in an extremely problematic context, such as contemporary Central America.
