Railtrack plc, floated in 1996, was the private sector owner of Britain's railway track, signals and stations. Its major source of revenue came from track access charges, which individual train operating companies (TOCs) paid for use of the infrastructure. Since many of these TOCs received substantial subsidies to assist in paying their track access charges, Railtrack was in effect being heavily subsidised. In October 2001, the Government decided that these arrangements were no longer viable and placed Railtrack into administration. This article explains how the level of indirect subsidies to Railtrack had become excessive, and raises crucial questions that need to be addressed in settling the future shape of the railway industry.  相似文献

As agricultural products move from being economic commodities to quality–differentiated goods, price dispersion within specific markets increases and implicit subsidies from high quality producers to low quality producers are removed. The present paper examines how these distributional effects can influence patterns of support and opposition to changes in marketing arrangements. The simple model developed is calibrated using data from the USA slaughter cattle market. Estimates of the impact on prices of measuring quality more accurately are found to be similar in size to previous estimates of market power price suppression in the market.  相似文献

Japanese stock returns are even more closely related to their book-to-market ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman (1997) tests on a Japanese sample, reject the Fama and French (1993) three-factor model, but fail to reject the characteristic model.  相似文献

Some 'real' problems of 'virtual' organisation   总被引:1,自引:0,他引:1  
This paper presents an ethnographic study of organisational change in a retail bank considering issues surrounding the supposed emergence of the 'virtual organisation'. It outlines emerging problems in organisational work as a consequence of the shift toward 'virtuality' and questions the explanatory value of such theoretical stances.  相似文献

In 1983, the Greater London Council adopted a policy of 'Contract Compliance' designed to ensure that firms selling goods and services to the Council complied with its equal opportunity requirements. The initiative aroused wide interest and many other local authorities - 40 are known of to date - have been considering introducing such a policy. Although simple in essence, its execution can be complex and difficult. In April 1986, the Inner London Education Authority, a partner in the GLC policy, took over the Contract Compliance Unit following the GLCs abolition. Linda Smith explains the background to contract compliance, how the GLC, now ILEA, operates the policy; assesses its achievements and its significance and explores some of the lessons learnt in its three years of operation.  相似文献

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

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
