Distance functions are gaining relevance as alternative representations of production technologies, with growing numbers of empirical applications being made in the productivity and efficiency field. Distance functions were initially defined on the input or output production possibility sets by Shephard (1953, 1970) and extended to a graph representation of the technology by Färe, Grosskopf and Lovell (1985) through their graph hyperbolic distance function. Since then, different techniques such as non parametric-DEA and parametric-SFA have been used to calculate these distance functions. However, in the latter case we know of no study in which the restriction to input or output orientation has been relaxed. What we propose is to overcome such restrictiveness on dimensionality by defining and estimating a parametric hyperbolic distance function which simultaneously allows for the maximum equiproportionate expansion of outputs and reduction of inputs. In particular, we introduce a translog hyperbolic specification that complies with the conventional properties that the hyperbolic distance function satisfies. Finally, to illustrate its applicability in efficiency analysis we implement it using a data set of Spanish savings banks.  相似文献

In a relatively short period of time, new immigration patterns have changed the geography of immigration of the EU15, bringing three old emigration countries, Ireland, Spain and Greece, to the forefront of the new immigration wave. This article studies the analogies and differences of the recent immigration experience of this group of countries, focusing on the demographic characteristics of the immigrants (origin, sex, gender and education), labour market insertion (wages, labour market segregation and quality of matching) and overall economic performance in terms of poverty rates.  相似文献

Energy supply and demand, and as a consequence energy prices, are likely to represent one of the biggest challenges of the 21st century. Commodity markets exhibit increased volatility when there is little or no underutilized supply capability to meet natural fluctuations in demand. In the case of energy markets, the large capital requirements and significant lead times associated with energy production and delivery make them more susceptible to the imbalances in supply capability and demand. Energy price volatility has destructive impact on market agents, and this impact is intensified when the prices exhibit asymmetric volatility. This article pursues two aspects of the issue. First we consider general aspects, especially the asymmetric pattern of volatility of daily returns of different types of energy products. Then, we analyze the behaviour of daily returns by using traditional models of volatility that include AGARCH, TGARCH, EGARCH, and ARSV strategies, as well as a threshold asymmetric autoregressive stochastic volatility (TA-ARSV) model that we propose. The energy products considered in this analysis are probably the most relevant energy products for the economic activity of the nations and the economic relations between countries: Crude Oil (OPEC reference basket and London Brent index), Gasoline, Natural Gas, Butane, and Propane. We use spot prices and the time reference ranges from 1986–1993 to 2009 depending on the product.  相似文献

abstract Much has been written on the nature of skills and the extent to which there is increased skills development or a deskilling of workers in modern workplaces. This paper broadens the debate and explores these issues in the novel context of UK‐ and Japanese‐
invested retailers' operations in China. Data derived from over two hundred interviews at twelve retail stores in six Chinese cities and questionnaires completed by almost eight hundred employees elicited contextualized accounts of interactive service workers' own perceptions of their training and skills development. It was found that these firms made a substantial contribution to skills development, fostered and enhanced both directly by company training and also through experiential workplace‐based learning. It might be, however, that this constitutes an essential but ‘one‐off’ increase in skills in transitional economies such as that of China.  相似文献

Mixed methods research is becoming an increasingly popular approach in several fields. However, its application in the field of entrepreneurship has not been studied. The authors reviewed the use of mixed methods research in three entrepreneurship journals and two leading generalistic journals that publish entrepreneurship research, examining the main purposes and designs. A total of 955 articles were reviewed and 81 mixed methods studies were identified. The analysis of these articles revealed opportunities associated with the application of this approach. Mixed methods may help to improve entrepreneurship research addressing challenges emphasized in earlier studies. Suggestions on why and how to use mixed methods research are offered, and recommendations are provided to guide future mixed methods studies to advance our understanding of the entrepreneurial phenomenon.  相似文献

The aim of this research is to conduct a quantitative analysis of the factors leading Spanish companies to adopt certain forms of organization that are typical of flexible businesses and high performance organizations. Despite the supposed inflexibility of the Spanish labour market, the results both point towards the high capacity of Spanish companies to select the form of work organization that best suits them and show the key role that competitive strategy plays when it comes to differentiating or segmenting types of work or workers, over and above the rigid working regulations that, purportedly, standardize labour relations in Spain.  相似文献

Benefit transfer is a method for estimating the value of environmental goods that involves the use of past information on identical or similar goods. This paper considers the extent to which benefit transfer can be based on prior distributions elicited from expert opinion. We propose two alternative methods to elicit the parameters of a prior distribution from experts on environmental valuation. An experiment is carried out on the value of National Parks in Spain. The results from the elicited distributions are compared with the information provided by onsite samples of visitors. The results indicate that individual experts made different predictions about the potential value of the policy areas that were diverse and unable to accurately predict the value for each policy site. However, the average across the elicited distributions approaches the estimated distribution with empirical data and accurately predicts the relative values for the two policy sites considered.  相似文献

This survey examines the empirical literature on the relationship between public R&D subsidies and private R&D investment over the past five decades. The survey reveals a considerable heterogeneity of empirical results that cannot be explained fully by methodological issues. We aim to provide further explanations of the possible causes of that heterogeneity. In particular, we emphasise a set of issues that, in our view, are critical to understanding the potential effect of public R&D subsidies on private R&D spending. Special attention is paid to the dynamic aspects and composition of firm R&D, the constraints faced by the firm (such as financial constraints), and the amount and source of public subsidies. None of these issues have been investigated in depth. We formulate a set of research assumptions to guide future empirical research in this field.  相似文献

Estimating Krugman’s Economic Geography Model for the Spanish Regions   总被引:1,自引:0,他引:1  
This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography.  相似文献
