This paper addresses: (1) the extent to which changes appear to have occurred in managerial strategies and labour and employment relations in Canadian firms, and (2) the role of the state relative to anonymous economic forces in accounting for Canadian developments. The general findings are that, while there have been a number of significant changes, these have been more moderate than expected by 'transformation' theory; furthermore, the Canadian case is consistent with the argument that state actions play a major role relative to more anonymous economic 'forces' in accounting for developments in labour and employment relations. It also suggests an alternative model to that typically assumed by transformation theory, one in which state policies and economic conditions are considered to be important not only for their direct effects on employer policies, but also for their indirect effects, through their implications for worker expectations and union militancy. Although these conclusions are tentative and call for more systematic, comparative research, they are consistent with arguments by Burawoy and others that state actions can serve as an important source of labour regulation at the level of the firm.  相似文献

Summary. This paper defines and studies optimality in a dynamic stochastic economy with finitely lived agents, and investigates the optimality properties of an equilibrium with or without sequentially complete markets. Various Pareto optimality concepts are considered, including interim and ex ante optimality. We show that, at an equilibrium with a productive asset (land) and sequentially complete markets, the intervention of a government may be justified, but only to improve risk sharing between generations. If markets are incomplete, constrained interim optimality is investigated in two-period lived OLG economies. We extend the optimality properties of an equilibrium with land and give conditions under which introducing a pay-as-you-go system at an equilibrium would not lead to any Pareto improvement.

This paper examines occupational performance in Australia across three racial groups in Australia: Indigenous Australians; Asian people, defined as all those whose language spoken at home was either Chinese, Vietnamese or other forms of a South-east or East Asian language; and white people, defined as the residual category. The paper has as its starting point, observed differences in occupational attainment among the three groups in Australia and sets out to account for these observed differences on the basis of both race and non-racial attributes such as, age, education and area of residence.  相似文献

In the present paper, risk‐management problems where farmers manage risk both through production decisions and through the use of market‐based and informal risk‐management mechanisms are considered. It is shown that many of these problems share a common structure, and that a unified and informative treatment of a broad spectrum of risk‐management tools is possible within a cost‐minimisation framework, under minimal conditions on their objective functions. Fundamental results are derived that apply regardless of the producer's preference towards risks, using only the no‐arbitrage condition that agricultural producers never forego any opportunity to lower costs without lowering returns.  相似文献

This paper explores the preferences that companies have as they use alternative (quasi) external sources of innovative competencies such as strategic technology alliances, mergers and acquisitions, or a mix of these. These alternatives are studied in the context of distinct industrial, technological and international settings during the first half of the 1990s. Different strategies followed by companies and the role played by routinized sets of preferences are also taken into consideration. The analysis demonstrates that these options are influenced by both different environmental conditions and firm specific circumstances, such as those related to protecting core businesses.  相似文献

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

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.  相似文献
