This article contrasts the characteristic structural and control profiles of educational organizations with those of technical organizations. A group of primary and secondary schools and the operating units of an industrial firm differed both in structural variables and in three activities of control: buffering, smoothing, and forecasting. the article suggests that educational organizations emphasize modes of control that operate on components peripheral rather than central to the organization's technical core.  相似文献

Abstract. In this paper we study the first–order efficiency and asymptotic normality of the maximum likelihood estimator obtained from dependent observations. Our conditions are weaker than usual, in that we do not require convergences in probability to be uniform or third–order derivatives to exist.
The paper builds on Witting and Nolle's result concerning the asymptotic normality of the maximum likelihood estimator obtained from independent and identically distributed observations, and on a martingale theorem by McLeish.  相似文献

Summary So far, the labour market has not received any special attention from macro-econometric model builders. In this article an attempt has been made to describe the labour market in detail, paying attention to such important phenomena as the friction between labour supply and demand, the heterogeneity of labour, the dependence of labour supply on the labour-market situation, the Phillips mechanism and the impact of real wages on labour demand. To make it suitable for policy simulations, the model has been extended to a complete macro-econometric model, taking account of the fact that both labour and capital limit the production possibilities.This paper summarises an extensive Dutch report on the construction of a model for the Netherlands labour market. The title of the original report is AMO-K: Een arbeidsmarktmodel met twee categorieën arbeid; (AMO-K, A labour-market model with two categories of labour) ; it was published by the Netherlands Economic Institute (NEI) in Rotterdam in the so-called Olive Series, 1982-2, pp. 403ff. Some details of the model presented in that report were changed after its publication; see G. den Broeder, AMO-K 81-12, Tussenrapport betreffende de verdere ontwikkeling van het arbeidsmarktmodel (Interim report on the further development of the labourmarket model), Rotterdam, September 1983. Since then, only minor changes have been carried through. The model reproduced in this paper is the modified version. The model was developed within the National Programme of Labour-Market Research (NPAO) (now defunct), the NPAO organisation having granted a commission to the NEI in Rotterdam.  相似文献

"This paper extends the standard (two-factor, one-good) model of international factor movements, to include unemployment due to a minimum-income guarantee within the capital-abundant country. From this country's perspective, we establish important departures from previous (full-employment) results. Most notably, our analysis shows that: (1) free factor mobility is worse than no mobility; (2) the optimal degree of labour migration is zero; and (3) national welfare can always be maximized by an optimal flow of capital. The analysis is then extended to examine: (1) illegal migration; (2) subsidization of employment; and (3) alternative views of unemployment."  相似文献
