The Stability Pact ‐ intended to make EMU governments run prudent budgets ‐ is losing its credibility. This article asks the question: what will happen if national debts start to rise again and some governments then have difficulty borrowing? It suggests that there will be calls for bailout, that the EU's political structures will not cope well with the resulting arguments over which countries will pay, and that the eventual and painful result will be a return to the principle that currencies and political areas coincide. 相似文献

This study investigates how participating in strategic alliances with rivals affects the relative competitive positions of the partner firms. The paper builds on studies that show significant differences in the outcomes of scale and link alliances. The study argues that the more asymmetric outcomes of link alliances translate into greater changes in the relative market shares of the partner firms, due to unbalanced opportunities for inter‐partner learning and learning by doing. We find support for this argument by examining 135 alliances among competing firms in the global automobile industry, from 1966 to 1995. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

This paper considers finite sample motivated structural change tests in the multivariate linear regression model with application to energy demand models, in which case commonly used structural change tests remain asymptotic. As in Dufour and Kiviet [1996. Exact tests for structural change in first-order dynamic models. Journal of Econometrics 70, 39–68], we account for intervening nuisance parameters through a two-stage maximized Monte Carlo test procedure. Our contributions can be classified into five categories: (i) we extend tests for which a finite-sample theory has been supplied for Gaussian distributions to the non-Gaussian context; (ii) we show that Bai et al. [1998. Testing and dating common breaks in multi-variate time series. The Review of Economic Studies 65 (3), 395–432] test severely over-rejects and propose exact variants of this test; (iii) we consider predictive break test approaches which generalize tests in Dufour [1980. Dummy variables and predictive tests for structural change. Economics Letters 6, 241–247] and Dufour and Kiviet [1996. Exact tests for structural change in first-order dynamic models. Journal of Econometrics 70, 39–68]; (iv) we propose exact (non-Bonferonni based) extensions of the multivariate outliers test from Wilks [1963. Multivariate statistical outliers. Sankhya Series A 25, 407–426] to models with covariates; (v) we apply these tests to the energy demand system analyzed by Arsenault et al. [1995. A total energy demand model of Québec: forecasting properties. Energy Economics 17 (2), 163–171]. For two out of the six industrial sectors analyzed over the 1962–2000 period, break and further goodness-of-fit and diagnostic tests allow to identify (and correct) specification problems arising from historical regulatory changes or (possibly random) industry-specific effects. The procedures we propose have potential useful applications in statistics, econometrics and finance (e.g. event studies). 相似文献

Kurt Lewin and the Planned Approach to Change: A Re-appraisal 总被引:3,自引:0,他引:3
Bernard Burnes 《Journal of Management Studies》2004,41(6):977-1002
abstract The work of Kurt Lewin dominated the theory and practice of change management for over 40 years. However, in the past 20 years, Lewin's approach to change, particularly the 3-Step model, has attracted major criticisms. The key ones are that his work: assumed organizations operate in a stable state; was only suitable for small-scale change projects; ignored organizational power and politics; and was top-down and management-driven. This article seeks to re-appraise Lewin's work and challenge the validity of these views. It begins by describing Lewin's background and beliefs, especially his commitment to resolving social conflict. The article then moves on to examine the main elements of his Planned approach to change: Field Theory; Group Dynamics; Action Research; and the 3-Step model. This is followed by a brief summary of the major developments in the field of organizational change since Lewin's death which, in turn, leads to an examination of the main criticisms levelled at Lewin's work. The article concludes by arguing that rather than being outdated or redundant, Lewin's approach is still relevant to the modern world. 相似文献

The authors examine the role of organizational factors affecting interdepartmental interactions and their subsequent effects
on product quality. Results from a national study suggest that product quality is affected by interdepartmental conflict and
connectedness. Importantly, the linkage between interdepartmental conflict and product quality appears to be robust across
varying levels of market turbulence and technological turbulence. In contrast, interdepartmental connectedness appears to
be more important for product quality under conditions of high market and technological turbulence. The results also indicate
that interdepartmental interactions are influenced by leadership characteristics (risk aversion of top managers), reward system
orientation, and organization structure (centralization, departmentalization, and hierarchical levels). Managerial implications
and directions for future work are proposed.

A bstract . Ethics and ethical thinking involve two primary and interdependent elements of analysis: the individual and the society. Economic thought dichotomized these two elements into the individual (competitive capitalism ) or the society (Marxist socialism ), with one element being the cause, and the other the effect. Views of economic reality were developed not on the basis of the interdependence of the individual and the society but their mutual antagonism.
Economic thought is based on the scientific reasoning of the seventeenth and eighteenth centuries. Its abstract definition of reality narrowed the significance of the concrete appearances of things in favor of the rules (science) that define things. Science requires both an objective causal order (independent of human definitions and beliefs) and the development of laws (independent of the human observer or participant) that explain the nature of the objective world. Ethical reasoning requires that economic causality be defined to include both the individual and the society. Ethical reasoning is needed to bring together both the scientific and the metaphysical for human meaning. The science of means must be joined to the human purposes of ends. 相似文献

In this paper the concept of a municipal welfare function is defined. It reflects the evaluation by local authorities of several levels of local expenditures. On the basis of an extensive survey among all Dutch municipal authorities these functions are estimated for about 550 Dutch municipalities with respect to total expenditures and differentiated with respect to several portfolios, like public works, education, etc. The variation of the estimated municipal welfare parameters is explained by objectively measurable municipal characteristics like the number of the inhabitants, age distribution of inhabitants and houses, number of unemployed, regional situation. 相似文献

This article describes the results of a research project which examined 171 alliances set up by competing firms in an international context. It presents an empirically-based taxonomy of such alliances constructed on the basis of a set of variables chosen for their demonstrated or assumed influence on the evolution and outcomes of strategic partnerships. Three contrasted types of alliances are identified: quasi-concentration alliances, market penetration alliances and shared supply alliances. They differ according to two fundamental dimensions: their symmetrical or dissymmetrical nature and the way in which they alter competition. Legal structure, often emphasized in previous research on the subject, does not emerge as a strongly discriminating factor. Hypotheses on the likely evolution and outcomes of each type of alliance are derived from the taxonomy.We are grateful to Barbara Gray, Stuart Hart, Aneel Karnani, Will Mitchell, Michel Tenenhaus, and to two anonymous reviewers for their very valuable and helpful comments on earlier drafts of this article. Our research project was funded by Fondation HEC, whose support we gratefully acknowledge. 相似文献

This study proposes a new approach to the estimation of daily realised volatility in financial markets from intraday data. Initially, an examination of intraday returns on S&P 500 Index Futures reveals that returns can be characterised by heteroscedasticity and time-varying autocorrelation. After reviewing a number of daily realised volatility estimators cited in the literature, it is concluded that these estimators are based upon a number of restrictive assumptions in regard to the data generating process for intraday returns. We use a weak set of assumptions about the data generating process for intraday returns, including transaction returns, given in den Haan and Levin [den Haan, W.J., Levin, A., 1996. Inferences from parametric and non-parametric covariance matrix estimation procedures, Working paper, NBER, 195.], which allows for heteroscedasticity and time-varying autocorrelation in intraday returns. These assumptions allow the VARHAC estimator to be employed in the estimation of daily realised volatility. An empirical analysis of the VARHAC daily volatility estimator employing intraday transaction returns concludes that this estimator performs well in comparison to other estimators cited in the literature. 相似文献
