Increasing exchange rate fluctuations, such as those that have occurred in the US dollar, have recently revived the discussion about the causes of such movements and the criteria for calculating the long-term over- or undervaluation of a currency. This article stresses some aspects that have attracted little attention hitherto.  相似文献

The Trans-European Automated Real-Time Gross settlement Express Transfer system (TARGET) imbalances within the Eurozone can be interpreted as a sign of a missing balance of payments adjustment mechanism for the member countries. As the Eurozone lacks a fiscal union, in theory it is more of an exchange rate union or a system of fixed exchange rates than a monetary union. This paper will show why the TARGET is a crucial indicator for the Eurozone not being a monetary union but instead an exchange rate union, and why countries holding TARGET liabilities against the European System of Central Banks can be compared to a reserve currency country, like the US under the Bretton-Woods System.  相似文献

The need for new methods to deal with big data is a common theme in most scientific fields, although its definition tends to vary with the context. Statistical ideas are an essential part of this, and as a partial response, a thematic program on statistical inference, learning and models in big data was held in 2015 in Canada, under the general direction of the Canadian Statistical Sciences Institute, with major funding from, and most activities located at, the Fields Institute for Research in Mathematical Sciences. This paper gives an overview of the topics covered, describing challenges and strategies that seem common to many different areas of application and including some examples of applications to make these challenges and strategies more concrete.  相似文献

This study focuses on three different milestones in the business gestation process, i.e. becoming an aspiring entrepreneur, a nascent entrepreneur, and a founder of a fledgling new business. Moreover, this study uses a combination of both individual and regional (or environmental) factors in predicting individuals’ success or failure to reach each of these three milestones. Hypotheses are developed to test the effect that human and environmental resources have on the odds of reaching the different milestones in the business start-up process. The study is based on interviews of a representative sample of 9533 Norwegians aged 18 years or older. From this group, 197 respondents qualified as nascent entrepreneurs. These were subsequently interviewed in follow-up interviews conducted in 1996, 1997 and 1999. In addition, regional data at the municipality level is included to measure the available pool of environmental resources. The results indicate that entrepreneurial experience is the single most important factor for predicting the outcome of the business start-up process. Even though environmental resources play a role, human resources are generally found to be better predictors of the outcome of the business start-up process. Several important implications for policy-makers are presented.  相似文献

Eine nachhaltige Finanzpolitik der L?nder sollte zu den Zielen einer F?deralismusreform geh?ren. Wie kann die Ver?ffentlichung von Indikatoren dazu beitragen, dieses Ziel zu erreichen? Welche Nachhaltigkeitskonzepte gibt es und wo liegen deren Chancen und Grenzen? Welche besonderen Probleme sind auf L?nderebene zu beachten? Dr. Beate Jochimsen, geb. Milbrandt, 38, ist wissenschaftliche Assistentin am Institut für ?ffentliche Finanzen und Sozialpolitik der Freien Universit?t Berlin.  相似文献

Die Finanzierung des Haushalts durch Kreditaufnahme ist für die St?dte und Gemeinden in Deutschland üblich. Ist diese Kreditaufnahme zu rechtfertigen? Was würde geschehen, wenn man sie verbieten würde? Wie ist in diesem Zusammenhang die Kreditaufnahme von Bund und L?ndern zu beurteilen? Prof. Dr. Horst Zimmermann*, 72, ist Emeritus des Lehrstuhls für Finanzwissenschaft an der Philipps-Universit?t Marburg, Mitglied des Wissenschaftlichen Beirats beim Bundesministerium der Finanzen und Vizepr?sident der Akademie für Raumforschung und Landesplanung in Hannover. * Der Beitrag wird Ende 2006 in einer Festschrift erscheinen.  相似文献

Although the share of older people in our society increases, the media sciences rarely examine this group of media users. Existing studies often limit themselves to chronological age and neglect a more theoretical approach. This study includes theoretical references from gerontological research, which describes aging as a multidimensional process, and links them to user-oriented perspectives of mass communication research. Referring to qualitative data from interviews with elderly people, the study achieves to identify prospects, appraisals and resources, which influence media use of people in the process of aging.  相似文献
