This study analyzes the effects of an important postderegulation innovation on rail freight productivity: the elimination of cabooses and related crew members. It also analyzes the overall growth of productivity in rail freight between 1983 and 1997 (using a translog rail cost function estimated over a sample of Class I railroads between 1983 and 1997). The results indicate that elimination of cabooses and associated crew members from freight trains reduced costs by 5-8% on the typical Class I railroad in 1997, equivalent to an annual cost saving of $2 billion to $3.3 billion for all Class I railroads. Moreover, if Class I railroads had no other technological advances since 1983, their 1997 costs (with 1997 factor prices) would have been 36-43% higher than they in fact were. Finally, the results show that overall productivity growth in rail freight did not decelerate between 1983 and 1997; if anything, it accelerated slightly.  相似文献

Australian sugar-producing regions have differed in terms of the extent and rate of incorporation of new technology into harvesting systems. The Mackay sugar industry has lagged behind most other sugar-producing regions in this regard. The reasons for this are addressed by invoking an evolutionary economics perspective. The development of harvesting systems, and the role of technology in shaping them, is mapped and interpreted using the concept of path dependency. Key events in the evolution of harvesting systems are identified, which show how the past has shaped the regional development of harvesting systems. From an evolutionary economics perspective, the outcomes observed are the end result of a specific history.  相似文献

The Stability Pact ‐ intended to make EMU governments run prudent budgets ‐ is losing its credibility. This article asks the question: what will happen if national debts start to rise again and some governments then have difficulty borrowing? It suggests that there will be calls for bailout, that the EU's political structures will not cope well with the resulting arguments over which countries will pay, and that the eventual and painful result will be a return to the principle that currencies and political areas coincide.  相似文献

Equity Volatility and Corporate Bond Yields   总被引:8,自引:0,他引:8  
This paper explores the effect of equity volatility on corporate bond yields. Panel data for the late 1990s show that idiosyncratic firm‐level volatility can explain as much cross‐sectional variation in yields as can credit ratings. This finding, together with the upward trend in idiosyncratic equity volatility documented by Campbell, Lettau, Malkiel, and Xu (2001), helps to explain recent increases in corporate bond yields.  相似文献

Open-bank assistance (OBA), provided to troubled banking institutions by the FDIC to prevent their failure, has been criticized extensively on grounds that closed-bank transactions, especially early closed bank transactions, are less expensive to the FDIC. This article analyzes a case in which OBA makes public policy sense, under conditions in which uncertainty is introduced into the valuation of a bank's nonperforming assets. Under such uncertainty, the FDIC may play a role by providing to the acquiror of the troubled institution essentially costless (to the FDIC) standby insurance on the ultimate workout values of the nonperforming assets. If properly structured, such an OBA transaction would meet critics' objections by minimizing FDIC cost and creating incentives for the early recapilization of troubled banks.  相似文献

The article considers six standard arguments in favour of an unfettered free market: (1) the freedom to consume; (2) the freedom of the seller; (3) the freedom of the producer; (4) freedom from government interference; (5) lower costs; (6) promotion of democracy. It demonstrates that each of these arguments turns out to be incoherent on closer examination. The ground of this incoherence it is shown, is the market doctrine's systematic omission of non-business costs and benefits from its analysis, a methodological blindness which can only be overcome by a wider-lensed comprehension of economic value.  相似文献

This article estimates economies of scale for a sample of five cellular telephony firms in the United States. We reject constant returns to scale for all but the smallest firm studied; the remaining firms exhibit decreasing returns to scale. This finding suggests that scale economies cannot be used to justify the current regulated duopoly structure of United States cellular markets.  相似文献

The authors propose a model for business ethics which arises directly from business practice. This model is based on a behavioral definition of the economic theory of profit maximization and situates business ethics within opportunity costs. Within that context, they argue that good business and good ethics are synonymous, that ethics is at the heart and center of business, that profits and ethics are intrinsically related.Marist Father Pat Primeaux is a Professor of Theology at Saint John's University, (New York). John Stieber is a Professor of Finance and Economics at Southern Methodist University's Edwin L. Cox School of Business (Dallas). They have collaborated on several articles on the behavioral dimension of economic efficiency. They have also designed and taught courses in business ethics at both the graduate and undergraduate level.  相似文献
