This article proposes and estimates an inflation indicator for the European Monetary Union (EMU). This indicator is set up so that it is contemporarily not affected by the changes in price differentials among EMU countries. The results show that the Monetary Union Index of Consumer Prices (MUICP), which is the inflation measure that the European Central Bank (ECB) takes as a reference for monetary policy purposes, could be understating the value of the inflation in the euro zone. It is also concluded that regional peculiarities are fundamental in the evolution of prices in the different EMU countries.  相似文献

One of the perceived advantages in mutual fund management is the presence of economies of scale resulting from fund size. This article analyses the impact of mutual fund cash flows on the relation between size and performance, demonstrating that performance determines asymmetric variations in fund assets, particularly in mutual equity funds. Therefore, the more efficient funds generate broad enough cash flow entry that increases the relative size of the fund, leading to an implicit and positive relation between size and performance. So, if the average size over the period sample is used as a measure of size, such a relation would be biased. When the initial size is used, this bias is avoided and, in general, an insignificant relation is found between size and performance. These results are controlled by mutual fund costs using gross returns to estimate performance. The evidence is robust, and shows only weak evidence of a negative relation between size and performance for the balanced funds that is driven by a low positive relation between costs and size; precisely, the contrary that is expected from the hypothesis of the presence of economies of scale.  相似文献

The severe consequences of a Critical Infrastructure (CI) crisis demand continued research directed toward proactive and reactive management strategies. Despite the best efforts of governments and communities, the diversity of stakeholders, conflicting demands for resources, and a lack of trust among organizations create complexities that limit the effectiveness of the response. This paper identifies four specific problems that appear to reoccur when CIs are challenged: heterogeneity, multiple and inconsistent boundaries, resilience building and knowledge transfer and sharing. A combination of collaborative modeling and software simulation methodologies is proposed in order to identify the interrelationships among diverse stakeholders when managing the preparation for and reaction to a CI crisis. This approach allows experts to work together and share experiences through the modeling process which can lead them to a better understanding of how other organizations work and integrate different perspectives. In addition, simulation models enable domain experts to understand the consequences of certain policies in the short and long terms, thus improving the crisis managers' knowledge for future crisis situations. This paper presents a practical case of a hypothetical crisis in the CI sector and the approach used in order to deal with the four problems identified above.  相似文献

Knowledge intensive services and, in particular, R&D services contribute significantly to innovation in firms. The objective of this paper is to find out which characteristics of firms explain the acquisition of R&D services and to analyse whether there are differences depending on the typology of the supplier (universities, technology centres and consulting firms). Three main conclusions emerge from the econometric estimations carried out with information from a survey of innovative firms in the region of Valencia in Spain. First, the results show that firm size and age matter in the decision to buy R&D services. Second, our results are consistent with the relevance that the literature gives to human capital in absorbing external knowledge. Third, innovation policy has a significant influence on the decision to acquire R&D services, particularly from universities and technology centres.  相似文献

This paper develops a dynamic duopolistic model of advertising and price competition. Advertising accumulates a stock of goodwill which enters directly into the demand functions and both the cooperative and predatory effects of advertising are considered. It is shown that firms invest more in advertising the higher the degree of cooperativeness of advertising and some comparative static results are provided. In the second, empirical part of the article, estimations of the demand equations are presented using data from the German automobile industry. The main conclusion drawn is that advertising plays an important role in this market and has a predatory nature.  相似文献

The purpose of the paper is to pinpoint the date of the change of monetary policy regime which occurred in Spain during the year 1984, when it moved away from controlling monetary aggregates towards interest rate targeting. The most likely date for the change is estimated and, surprisingly, there is evidence that agents learned about the new intermediate target quite rapidly.A week after the change, the term structure of interest rates showed how market agents attributed much more informational content to interest rate changes than they had previously. Two types of transitions are tried: a one-step and a gradual logistic swithing function.  相似文献

In the field of territorial economic growth, it is possible to identify important characteristics in the entrepreneurial structure, such as the structure of the size of firms, main activity sectors, or the degree of innovation. However, other lesser known characteristics are important also, such as functional dependency, which considers the relationship between small and medium enterprises (SMEs), and suppliers and clients belonging to any territorial field or productive dependency, which considers the level of concentration in terms of buying and selling in connection with the main suppliers and clients, respectively. In order to empirically contrast the importance of these entrepreneurial characteristics and try to relate them with territorial economic growth, a sample of 400 enterprises in the province of Seville (Spain) is used.   相似文献

The willingness to pay (WTP) for a coyote conservation program is estimated using a novel payment-vehicle, based on how many ‚problem’ coyotes respondents would be willing to sponsor for a year. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince Edward Island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses. This is particularly important in the case of coyotes, often regarded as an economic bad. Estimates of WTP per coyote per year around $18–$22 and annual WTP per contributor of about $46–$57 are obtained.   相似文献

Environmental Product Differentiation and Environmental Awareness   总被引:1,自引:0,他引:1  
In this paper, we have considered a duopolistic model of environmental product differentiation with two types of consumers (green and brown) to analyze how environmental awareness affects the environment. “Green” consumers value the physical and environmental attributes of the good they purchase while “brown” consumers only value the physical attributes. We find that more environmental awareness may not be good news for the environment as the firm that produces the good without environmental attributes may increase its sales. The result depends on the degree of product differentiation and the cost to achieve it. Social welfare can also be inversely related to environmental awareness if the negative environmental effect dominates the positive market effect.   相似文献
