Money Demand and Monetary Policy in Europe.—The European Central Bank will soon have to decide on her monetary strategy. This paper discusses properties of money demand functions and implications for monetary policy in a monetary targeting regime. Special attention is paid to different concepts of stability of money demand, to the length and variability of adjustment lags, and to the controllability of the money stock. At the European level, stable money demand functions are identified for M1 and M3. However, M3 appears to be less controllable than M1. Long and variable adjustment lags in the demand for M3 weaken the case for broad money as a monetary target. JEL no. E41, E52  相似文献

The reduction of energy-related CO2 emissions by more efficient enery use in medium sized companies is one of the most profitable options. However, these opportunities are scarcely realised because of many obstacles and market failures. High transaction cost and decision routines play an important role for decision making and procurement of the companies. A network concept being developed in Switzerland and covering an initial consulting of each participating company, targets for the network, regular and moderated meetings of the energy managers for mutual exchange of experiences and a yearly monitoring alleviates many of these obstacles. It doubles the energy efficiency progress relative to the average progress of industry. This network concept can be fully realised by industry itself. Average energy savings per site and year are 100,000 € and average CO2 emission reduction about 500 t CO2 per year and site. Assuming a maximum potential of 700 Networks, additional emission reductions of some 10 Mio. t CO2 seem to be possible in Germany by 2020. A network management system for consulting engineers and moderators allows a minimum performance standard of how to start and operate those efficiency networks.  相似文献

We demonstrate how an evolutionary agent-based model can be used to evaluate climate policies that take the heterogeneity of strategies of individual agents into account. An essential feature of the model is that the fitness of an economic strategy is determined by the relative welfare of the associated agent as compared to its immediate neighbors in a social network. This enables the study of policies that affect relative positions of individuals. We formulate two innovative climate policies, namely a prize, altering directly relative welfare, and advertisement, which influences the social network of interactions. The policies are illustrated using a simple model of global warming where a resource with a negative environmental impact—fossil energy—can be replaced by an environmentally neutral yet less cost-effective alternative, namely renewable energy. It is shown that the general approach enlarges the scope of economic policy analysis.  相似文献

A study was undertaken to understand why cost overruns and schedule delays have occurred and continue to occur on large‐scale U.S. Department of Defense and intelligence community programs. Analysis of data from this study infers the causes of cost overruns and schedule slips on large‐scale U.S. federal defense and intelligence acquisition programs to ineffective human resources policies and practices, consolidation of the aerospace industry, and too many stakeholders. In this article, each inferred cause and the resulting systematic effects are discussed in detail. Moreover, block diagrams have been developed for each cause and illustrate the sequential flow from inferred cause to systematic effects and reveal key interrelationships among each cause.  相似文献

Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this article we present the first analysis of the effect of language on trade in an intra‐national context. Analyzing unique data for a single‐language country, Germany, we find that similarities in the local dialect have a significantly positive impact on regional trade. We interpret this finding as evidence for the trade‐promoting effect of culture, because linguistic similarities likely reflect cultural ties across regions, rather than lower costs of communication or similar institutions.  相似文献

Zusammenfassung  Die Bundesregierungen verfolgen seit langem — zum Teil durch das Bundesverfassungsgericht dazu veranlasst — das Ziel, niedrige Einkommen steuerlich zu entlasten. Mit dem Konjunkturpaket II wurden wiederum Tarifkorrekturen für 2009 und 2010 beschlossen. Welche Folgen diese Politik seit 1990 für die mittleren Einkommen hat, zeigt Volker Stern vom Karl-Br?uer-Institut des Bundes der Steuerzahler. Volker Stern, 55, Dipl.-Volkswirt, ist Mitarbeiter im Bereich Haushaltspolitik, Steuerpolitik und Steuerrecht des Karl-Br?uer-Instituts des Bundes der Steuerzahler in Berlin.  相似文献

Reviewing the evolution of Chinese economic aid, it can be found that the People’s Republic, though labouring under relatively adverse conditions, has proved its mettle in this field by actively supporting less developed countries (LDCs) over many years.  相似文献
