We investigate whether recent changes in welfare policy affect the migration of low-educated unmarried mothers. Estimates indicate that welfare reform is associated with an increase in employment-related intrastate migration, and a decrease in non-employment related migration, both within and between states. The net effect was a small increase in intrastate migration and a small decrease in interstate migration. The close link between migration and employment suggests that welfare reform has motivated low-income women to move for economic reasons. In general, welfare policy appears to have a much larger effect on residential location because of its relationship to employment than because of benefit differences between states. 相似文献

Tom Sorell 《Journal of Business Ethics》1994,13(11):913-918
Consumers can sustain markets that are morally questionable. They can make immoral or morally suspect demands of individual businesses, especially small businesses. Even when they do not, the costs to firms of consumer protection can sometimes drive them to ruin. This paper presents cases where deference to the consumer is variously unwarranted, cases that may prompt second thoughts about some kinds of consumerism.Tom Sorell is Reader in Philosophy at the University of Essex. He was educated at McGill University and Oxford. He is on the editorial board ofBusiness Ethics: A European Review, and is the author (with John Hendry) ofBusiness Ethics (Butterworth-Heinemann, 1994). 相似文献

The main. nancial goal of Progressive Insurance, the third largest underwriter of auto insurance in the U.S., has remained the same since the late 1960s. Expressed in three words, "96 and grow," the goal tells the company's managers to pursue all growth opportunities while maintaining a "combined ratio" no higher than 96, or what amounts to a minimum 4% spread between revenues (premiums) and costs (including expected losses). Thanks in part to the clarity of mission provided by this goal, the company has produced an average 15% rate of growth in revenues and earnings, along with a remarkably stable 15% return for its shareholders, since going public in 1971.
Progressive's simplicity and clarity of mission is also partly responsible for another of the company's distinctive policies: product pricing that, while disciplined, is aggressive and highly decentralized. Having invested some $500 million per year developing statistical models for pricing individual customer risks and acquisition costs, the company was among the. rst in its industry to underwrite "non-standard" risks. And aided by sophisticated pricing models, each of Progressive's 100 or so local product managers are charged with adapting those models to come up with premiums for their own regions.
To go along with its strategic and organizational innovations, Progressive also has an innovative disclosure policy. Apart from SEC reports, the company's communications seldom mention earnings or earnings per share, and the company has never provided earnings guidance. With the passage of Reg. FD in late 2000, the company brie. y considered offering guidance. But in the spring of 2001, the board decided instead to provide monthly releases of its realized combined ratio. Since adoption of this new disclosure policy, Progressive has seen a 50% drop in the volatility of its stock price. 相似文献

In Search of Theory Development in Grounded Investigations: Doctors' Experiences of Managing as an Example of Fitted and Prospective Theorizing 总被引:1,自引:0,他引:1
This article draws on a study of doctors’ experiences of clinical managing to highlight research conventions that limit the development and use of middle range theories in grounded studies. Using sensemaking and the psychological contract as example frameworks, we illustrate how customary deductive evaluations of middle range theories turn grounded researchers away from theory building. As a correction to these conventions, we offer an inductive approach to building existing theory in grounded investigations that does not depend solely on working with frameworks under different empirical conditions. We suggest that forward theorizing is most likely to progress from a synthesis of fitted explanation and prospective thinking that presses at the limits of the data's usefulness. To illustrate this approach, trialled thinking about novel theoretical juxtapositions and alternative sources was used in conjunction with our clinical director data. The value of this approach was supported in two ways. First, a number of fitted and prospective conjectures are offered about how social identity articulates with psychological contracts and sensemaking in role change situations. Second, new light is shed on the process by which particular social conditions differentially modify employees’ social categorizations, and how these inform employee responses to the evolving experience of role change. The article concludes with some tentative proposals for promoting more discussion of theory building in grounded investigations. 相似文献

This paper is interested in the modelling of the relationship between active and passive labour market policies and the aggregate unemployment outflow rate. Our model is based on a matching function and includes a simple representation of the competition between various groups of job searchers. The empirical analysis uses Belgian data. Faced with variables that are often integrated of order 1 according to the usual tests but which cannot strictly speaking be integrated, we contribute to an important methodological debate by comparing the conclusions of a classical econometric analysis and a cointegration approach. 相似文献

A bilinear multivariate errors-in-variables model is considered. It corresponds to an overdetermined set of linear equations
AXB=C, A∈ℝm×n, B∈ℝp×q, in which the data A, B, C are perturbed by errors. The total least squares estimator is inconsistent in this case.
An adjusted least squares estimator is constructed, which converges to the true value X, as m →∞, q →∞. A small sample modification of the estimator is presented,
which is more stable for small m and q and is asymptotically equivalent to the adjusted least squares estimator. The theoretical
results are confirmed by a simulation study.

Tom Wilson 《Industrial Relations Journal》1991,22(4):250-262
This article looks at industrial relations changes, conflict and control in higher education, particularly among university academics. It suggests a tendency towards proletarianisation, and a focus on the academic labour process is useful in explaining growing conflict. An apparent HRM agenda and (reluctantly) increasing managerialism are forms, not causes, of change which is driven by funding pressures similar to those affecting other HE systems. 相似文献

The EU has neither the power to tax nor the right to run a public debt. We analyze if the EU should receive the right for public indebtedness. We make use of the normative theory of public indebtedness and of positive political economy analysis. Our normative analysis identified specific cases for an appropriate use of public indebtedness. According to the political economy analysis, a misuse of public debt may be possible. As the implementation of strict constitutional constraints can limit this misuse, we propose the assignment of a right to public borrowing to the EU within tight constitutional restrictions. 相似文献
