This article examines the "squaring the welfare circle" thesis and its usefulness to our understanding of welfare developments in Greece and Spain in the 1990s. The welfare state in both Greece and Spain was expanded considerably in the early 1980s by the newly elected socialist governments, only to hit the buffers of diminishing resources and rising demands in the late 1980s as well as the hostile neo-liberal welfare ideology. The process of welfare expansion was halted in the 1990s, labour market deregulation was encouraged and containment of welfare expenditure became the dominant aim of government policies. This article concentrates on the actual policies of governments in the 1990s rather than on the rhetoric of political parties. It concludes that governments of both the Left and the Right in both countries attempted to "square the welfare circle" mainly through reductions in the supply of welfare. This general conclusion is country-specific and may not apply to other countries involved in welfare restructuring. While recognizing the significance of institutional factors to welfare reform, the article concentrates on the outcomes of reforms rather than on the political process leading to them. 相似文献

When the method of least squares is used to estimate the parameters in a general model and the generated system of normal equations is linearly dependent, the estimate of the vector of parameters which satisfies the criterion is not unique. However, there exist certain functions of the estimated vector of parameters which are invariant to the least squares solution obtained from the normal equations. We define those invariant functions to be estimable, and present a technique to determine the functions of the parameters which are estimable for the general model. The method results in solving either a linear first order partial differential equation or a system of linear first order partial differential equations corresponding, respectively, to a single or multiple dependency between columns of the Jacobian matrix of the mean of the model. The usual results concerning estimability for linear models are a special case of the general results developed. 相似文献

Abstract In ‘Defending the City’ George Pattison seeks to defend the modern city against the charge — made, for example, by Graham Ward — that it is a merely secular phenomenon. Instead, he argues that, in its essence, it is multi‐dimensional and pluralistic, representing a range of diverse possibilities, creative as well as destructive. Also, the modern city is shown to anticipate the essential features of the postmodern city. The argument is illustrated by references to Pugin's critique of architectural eclecticism, to Dostoevsky's invocation of the fantastical reality of St. Petersburg, to Kierkegaard and to Murnau's film Sunrise. It is claimed that the best Christian response to the city is to defend, not to subvert, its pluralism. 相似文献

Two often-quoted necessary and sufficient conditions for ordinary least squares estimators to be best linear unbiased estimators are described. Another necessary and sufficient condition is described, providing an additional tool for checking to see whether the covariance matrix of a given linear model is such that the ordinary least squares estimator is also the best linear unbiased estimator. The new condition is used to show that one of the two published conditions is only a sufficient condition. 相似文献

In this note, we report a dramatic improvement in the computational efficiency of semiparametric generalized least squares(SGLS) estimation. Computation of SGLS estimates no longer presents serious problems with data sets of moderate size. We also correct a numerical error in the standard errors of the SGLS estimates reported in our recent paper in this journal (Horowitz and Neumann, 1987). The corrected standard errors of SGLS are comparable to those we reported for quantile estimates. 相似文献

This study examines perception of various business practices of Russian and American managers. Using data collected from 136
Russian managers and 252 American managers we found that cross-national differences account for many differences between perceptions
of business practices. Implications for managerial practice are discussed.

Assuming a statistical model in which the joint distribution of the unobservable errors is drawn from independent univariate Student t's that are identically and symmetrically distributed, the sampling performance of traditional robust estimators and a family of Stein-like estimators are compared and evaluated. These results suggest that under thick-tailed distributions, the relative sampling performances and risk characteristics for a range of nonconventional Stein estimators remains approximately the same as in the case of their normal counterparts. The empirical risk implications of misspecifying the error distribution are investigated. 相似文献
