Regulatory Control of the Track Access Charges of Railtrack plc

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.     

The political economy of quality measurement: a case study of the USA slaughter cattle market

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.     

Länger leben — Siechtum und Pflege ohne Grenzen?

At present, our society and its social security system are not prepared to cope with the challenges resulting from the continuous increase of life expectancy. The traditional concept of disease has to be modified for serving the special needs of the elderly. The optimistic compression of disease theory is an intriguing model, but lacks prove by available data. The anti-aging boom diverts the focus from the social and financial burden that will be unevitably caused by long-term care in the future. If there will not be an — up to now unforeseeable — breakthrough in research, particularly dementia will have an enormous impact on social cost which is often underestimated.

Explaining the Cross‐Section of Stock Returns in Japan: Factors or Characteristics?

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.     

Some 'real' problems of 'virtual' organisation

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.
