This paper investigates the production efficiency of 12 European banking systems over the period 1997–2004, taking into account possible technology heterogeneity. Using a non-parametric metafrontier framework, efficiency and metatechnology ratio measures are computed and decomposed into input- and output-invariant components. Empirical findings indicate the existence of significant and rather increasing technology heterogeneity within European banking. A typology of the national banking systems is also developed, based on the overall productive performance with respect to the European technological edge, the absorptive capacity and the role of knowledge spillover effects. Decomposition results draw attention to catching up policies focusing on input and/or output scale adjustments.  相似文献

A decomposition analysis for consumer demand functions is developed. Changes in Marshallian demand or expenditure shares functions over time are decomposed into a total substitution effect, an income effect, and a habit effect. This framework is applied to post-war Greek consumption patterns through a habit persistence version of the Quadratic Almost Ideal Demand System (QUAIDS). It is found that for all commodity categories (i.e., food, beverages and tobacco, footwear and clothing, settling and housing, and others) the income effect was the main driving force in explaining changes in both quantity demanded and expenditure shares, followed by habit and total substitution effects.  相似文献

This article presents an integrated framework for testing the effects of productive efficiency, i.e. technical efficiency (TE) and scale efficiency (SE), on firm exit, facilitating the identification of the effects, causing a firm's operation at increasing or decreasing returns to scale. A panel data set of firms in the plastics and rubber industry of the Greek manufacturing sector is used to study the effect that TE and SE may have on a firm's probability to exit. Results reveal that technical efficiency is the most critical factor influencing firm exit, while SE exerts a quadratic effect on the probability to exit.  相似文献

Cognitive radio (CR) is considered a promising technology that could provide important benefits in the telecommunication domain. In Europe, the number of research projects, standardization activities and public consultations by the European Commission and regulatory authorities testify to the growing interest in CR. The introduction of CR in the telecommunication market may require new regulations or changes to the way spectrum is licensed and the conditions under which it can be used. The concepts of CR can be applied to various operational scenarios, which are described in this paper.This paper identifies the main challenges for the deployment of CR technology in Europe, provides an overview of the activities by European regulatory and standardization bodies to address the identified challenges and describes a roadmap with potential actions to support the adoption of CR technology.  相似文献

The importance of specific crop sectors can be better cast in a broader framework to account for intersectoral effects. Input-output analysis can provide this framework to assess the importance of the controversial crop, tobacco. In this respect, employment, income, and output multipliers were estimated to demonstrate the dynamics of the sector at the regional and national levels. Furthermore, the impact of totally eliminating tobacco cultivation was computed. Results clearly demonstrate the significance of the tobacco sector and its interrelation with the rest of the economic sectors.This study was partially financed by the Portuguese Association of Tobacco Producers.  相似文献

Studying the factors that contribute to the development of skiing loyalty holds particular interest for ski resort managers and marketers, since it has been reported that recreational skiers’ dropout rates are considerably high. This study examines how intrapersonal, interpersonal and structural constraints, influence the development of skiers’ stage-based attitudinal loyalty (Attraction, Attachment and Allegiance stages), as conceptualised by the psychological continuum model, and further tests if constraints can be used for classifying skiers into the three stages of the model (Attraction, Attachment and Allegiance). Two hundred and thirty (N = 230) recreational skiers from one ski resort in North Greece participated in the study. The results indicated that the intensity of perceived constraints decreased from the lowest (attraction) to the highest (Allegiance) stage of the model. However, the hierarchical influence of constraints was not entirely confirmed, since all three types of constraints contributed to the stage classification of recreational skiers. The theoretical and applied implications of these results are discussed.  相似文献

Economic expansion indirectly promotes class diversification at the neighbourhood scale with a consequent reduction of social divides at the regional scale. To verify this working hypothesis, the present study investigates class diversification at both spatial scales in a Mediterranean city (Athens, Greece) using the European Socioeconomic Classification based on population census data referring to 1991–2001, a phase of economic expansion and intense urban sprawl preceding the 2004 Olympic games. Results of multivariate analysis and diversity indexes outline a local-scale social mix associated to suburban expansion, and regional-scale class segregation, reflecting an increasing polarization in affluent and economically deprived urban districts. The contrasting pattern at the two spatial scales results in a complex social geography with class diversification and moderate changes over time in the economic spatial divide between urban and neighbouring rural areas. These findings contribute to design scale-dependent policies reducing social inequalities and improving quality of life in urban areas. Future paths for socio-spatial processes were delineated for sprawling metropolitan regions under economic expansion and discussed in the light of future demographic trends in both developed and emerging countries.  相似文献

We estimate the duration of out-of-work periods in the German labour market from 1980–90 and their relationship with employment protection legislation. We distinguish between Employment Interruptions that are legally protected and ordinary Layoffs. We investigate the question of whether the size of employer has an impact on the choice of the type of temporary separation. We find that firm size does matter, in both the type and the duration of temporary separations, and we examine the complex re-hiring process.  相似文献

We show that exact computation of a family of ‘max weighted score’ estimators, including Manski’s max score estimator, can be achieved efficiently by reformulating them as mixed integer programs (MIP) with disjunctive constraints. The advantage of our MIP formulation is that estimates are exact and can be computed using widely available solvers in reasonable time. In a classic work-trip mode choice application, our method delivers exact estimates that lead to a different economic interpretation of the data than previous heuristic estimates. In a small Monte Carlo study we find that our approach is computationally efficient for usual estimation problem sizes.  相似文献
