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

Relations between rich and poor (across and within countries) appeared in some questions in Images; there were clear differences between what the powerful and the powerless hoped and expected from the future. This is compared with what actually happened and a deeper analysis is made of ‘power’ as an organizing concept. It turned out that the pessimism associated with powerlessness tended to make better predictions. 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

This paper employs a latent variable approach to isolate the effects of changing tastes on the share of total meat expenditure on different categories of meat products in Greece during the period 1965–1995. We find that changes in the relative expenditure on different categories of meat cannot be explained by changes in the relative prices of the different meat products and increased expenditure alone. For pork products in particular, the increase in the share of expenditure has been greater than would be expected as a result of the relative fall in their price. The increase can therefore be associated with changes in taste. This finding is of general interest to those conducting empirical research into consumer behaviour both in economies where there have been significant changes in patterns of food consumption, and where, as in the case of many less industrialised economies, rapid structural changes in food consumption patterns are still to come. It is also of importance to policy makers in assessing die effectiveness of advertising or promotional campaigns in influencing longer term changes in consumer preferences for different products. 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

We characterize optimal time profiles of risk-reducing expenditures and wreck probabilities for petroleum platforms. The input to our analysis is the development of wreck cost, direct and imputed. Particular attention is paid to the question of how private companies deviating from socially optimal standards may be induced to comply with such standards by means of a) a time-variant penalty, b) a no-wreck bonus and c) a time-invariant penalty. 相似文献
