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

Models for which the MLE and the conditional MLE coincide 总被引:1,自引:0,他引:1
The MLE, CMLE and MMLE coincide in a linear regression model with fixed individual effects. In this case, there is no incidental parameters problem and the MLE is consistent. The equivalence of these estimators is important because CMLE=MLE implies both the consistency of the MLE and the efficiency of the CMLE. In general, we cannot expect to find a CMLE or MMLE, since there may be no fixed-dimension sufficient statistic for the effects, nor an appropriate transformation of the data whose distribution does not depend on the effects. However, we show that the MLE, CMLE and MMLE do coincide in systems of seemingly unrelated regressions and in systems of simultaneous equations. We establish this result for systems in which (exogenous) variables in addition to (or other than) the intercept may have coefficients which vary over individuals, provided that the set of such variables is the same in every equation.The financial support of the National Science Foundation is gratefully acknowledged. 相似文献

This paper is concerned with one central question: the choice between theories, and the role played by data in that choice. It deals with the uses economists may make of data and the importance of understanding the institutional basis that gives rise to the data - an area in which labour economists have traditionally been particularly strong - and with the relevance of assumptions. It deals with the ultimate need to choose between competing theories (despite the role of conventionalism) on the basis of data rather than retreating into a comfortable 'methodological pluralism'. It considers the role of test replication, with reference to the practice in natural science (and its role there in checking scientific fraud) and concludes that, despite extensive technical problems of testing, economists have to accept a data check if the rhetoric of mathematical technicality is not to overwhelm the need to explain. Parallels are drawn with experience in physics (and the implications of the development of Chaos and Catastrophe for a naively predictionist view are noted), medicine and history (of which, it is argued, modern economists are far too neglectful). 相似文献

The feminization of poverty refers to female householders and their children becoming an increasing percentage of the poor
population. After examining effects of race on poverty of female-headed households from 1959 to 1989, this study investigates
statistical relationships among female poverty, economic and labor market conditions, and transfer payments (specifically
AFDC) by means of the Granger causality test over the period from 1966 to 1988. This study reinforces the plausible assumption
that policies which would lower the unemployment rate of females and would increase real economic growth could be expected
to reduce the number of poor female households. 相似文献

Our examination of the cross-section of expected returns reveals economically and statistically significant compensation (about 6 to 9 percent per annum) for beta risk when betas are estimated from time-series regressions of annual portfolio returns on the annual return on the equally weighted market index. The relation between book-to-market equity and returns is weaker and less consistent than that in Fama and French (1992). We conjecture that past book-to-market results using COMPUS-TAT data are affected by a selection bias and provide indirect evidence. 相似文献

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

External Sources of Innovative Capabilities: The Preferences for Strategic Alliances or Mergers and Acquisitions 总被引:2,自引:0,他引:2
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
