Zusammenfassung Zum “trade-off” zwischen Lohnindexierung und Intervention auf dem Devisenmarkt. - In diesem Aufsatz analysieren die Verfasser die Beziehung zwischen dem optimalen MaΒ für Lohnindexierung und dem für Wechselkursinterventionen. Die optimalen Gr?Βen für diese beiden wirtschaftspolitischen Instrumente werden mit Hilfe einer gemeinsamen Optimierung unter Berücksichtigung ihrer wechselseitigen Interdependenz ermittelt. Das bei der Untersuchung verwendete Modell wird gepr?gt durch die Charakteristika der stochastischen Schocks, die die Volkswirtschaft beeinflussen, und durch das Informations-bündel, das die Wirtschaftssubjekte annahmegem?Β besitzen. In der Analyse wird sowohl geprüft, wie der optimale Lohnindexierungsgrad mit dem gesamten Spektrum m?glicher Wechselkurssysteme zusammenh?ngt, als auch untersucht, wie das optimale AusmaΒ der Wechselkursinterventionen von dem gesamten Spektrum m?glicher Lohnindexierungsgrade abh?ngt. Eines der Hauptergebnisse ist, daΒ es keine monotone Beziehung zwischen den optimalen Werten der beiden wirtschaftspolitischen Instrumente gibt. Worin der “trade-off” zwischen ihnen genau besteht, wird in der Untersuchung im einzelnen dargelegt.
Résumé Le ?trade-off? entre l’indexation salariale et l’intervention en taux de change. — Dans cet article les auteurs analysent la relation entre les degrés optimum de l’indexation salariale et l’intervention en taux de change. Les valeurs optimum des deux instruments de politique sont obtenues par une ?optimisation? jointe considérant leur interdépendance mutuelle. Le modéle utilisé est déterminé par les caractéristiques des chocs stochastiques qui affectent l’économie et par les informations des individus. L’ analyse examine la dépendance du degré optimum de l’indexation salariale du spectre total des régimes possibles de taux de change et, vice-versa, la dépendance du degré optimum de l’intervention du spectre total des degrés possibles de l’indexation salariale. Un des résultats principaux est l’absence d’une relation monotone entre les valeurs optimum des deux instruments de politique. De plus, l’analyse détermine la nature précise du ?trade-off? entre eux.

Resumen Sobre el ?trade-off? entre la indexaci?n de salarios y la intervenci?n en el mercado de cambios. - En este trabajo los autores estudian la relaci?n entre grados óptimos de indexaci?n de salarios y de intervenci?n en el mercado de cambios. Mediante una optimizaci?n simultánea, que toma en cuenta la interdependencia de estas medidas, se obtienen valores óptimos para ambos instrumentos de politica económica. El modelo utilizado incorpora las caracterfsticas de los shocks estocásticos que afectan a la economfa y el conjunto de informaciones a disposici?n de los individuos. El análisis examina la dependencia del nivel ?ptimo de indexaci?n de salarios de todo el espectro de polfticas cambiarias posibles, como también la dependencia del nivel ?ptimo de intervenci?n en el mercado de cambios de todo el espectro de grados de indexaci?n de salarios posibles. Uno de los resultados centrales es la ausencia de una relaci?n monot?nica entre los valores óptimos de ambos instrumentos; en el análisis se détermina la naturaleza exacta del ?trade-off? que existe entre ellos.

This paper studies the institutional design of the coordination of macroeconomic stabilization policies within a monetary union in the framework of linear quadratic differential games. A central role in the analysis plays the partitioned game approach of the endogenous coalition formation literature. The specific policy recommendations in the European Economic and Monetary Union (EMU) context depend on the particular characteristics of the shocks and the economic structure. In the case of a common shock, fiscal coordination or full policy coordination is desirable. When anti‐symmetric shocks are considered, fiscal coordination improves the performance but full policy coordination does not produce further gains in policymakers' welfare.  相似文献

We analyse additive regression model fitting via the backfitting algorithm. We show that in the case of a large class of curve estimators, which includes regressograms, simple step-by-step formulae can be given for the back-fitting algorithm. The result of each cycle of the algorithm may be represented succinctly in terms of a sequence of d projections in n-dimensional space, where d is the number of design coordinates and n is sample size. It follows from our formulae that the limit of the algorithm is simply the projection of the data onto that vector space which is orthogonal to the space of all n-vectors fixed by each of the projections. The formulae also provide the convergence rate of the algorithm, the variance of the backfitting estimator, consistency of the estimator, and the relationship of the estimator to that obtained by directly minimizing mean squared distance.  相似文献

Summary The German economy is usually assumed to take a leading position. In principle this gives smaller countries, which are dependent on Germany, the opportunity to predict their own economic future conditional on the state of the German economy. This paper uses this opportunity for The Netherlands by applying a Vector Auto Regressive model on Dutch and German series. Because the traditional VAR models appear to be overparameterized, their forecast performance can be improved significantly by using shrinkage estimators based on the so-called Minnesota prior. Such a Bayesian VAR forecasts well and confirms the interdependence between Germany and The Netherlands. Variance decomposition of forecast errors and impulse response simulations strengthen the impression that the BVAR model properties are plausible.The author works at the Econometric Research and Special Studies Department of the Nederlandsche Bank.

In many organizations people need to locate colleagues with knowledge and information to resolve a problem. Computer-based systems that assist users with finding such expertise are increasingly important to industrial organizations. In this paper we discuss the development of Expertise Finders suitable for use within the engineering design environment, as illustrated through the use of a scenario. A key feature of this work is that the Expertise Finder returns both recommended contacts and supporting documentation. The Expertise Finder bases its results on information held within the organization, e.g. on-line publications repositories, human resource records, and not on individually compiled Curriculum Vitaes or other forms of user-maintained records. The recommendations are presented to the user with due regard to the social context, and are supported by the documents used to make the recommendation.

Marketing decisions are particularly vulnerable to legal rulings made in both the courts and the legislatures. The effective management of those legal implications challenges the modern marketing professional. Grasping marketing’s overall legal environment, including its governing case law, regulatory statutes and future trends, is essential. This review will provide analysis of recent court cases and legislation with particular emphasis on creatively assisting the marketer’s management of the legal factor.  相似文献

The role of time and mood as consumer behavior constructs has seen increasing independent attention over the past several years. Two studies on the impact of transient affective states on consumers' temporal judgments are reported. In accordance with the research hypotheses, both studies demonstrated strong mood effects on subject's time perception and orientation. The findings were validated across two different mood-inducing manipulations and supported the general theoretical foundation of the mediating roles of affective states on consumers' temporal judgments. © 1993 John Wiley & Sons, Inc.  相似文献

According to software vendors and consultants, Enterprise Resource Planning systems (ERPs) transform the nature, structure and management of work regardless of organisational context. This paper contests this technologically deterministic view of organisational change by demonstrating the role that discourse plays in the social construction of ERPs.  相似文献
