Several studies have demonstrated how to use DEA (Data Envelopment Analysis) based techniques to estimate environmental performance indices. None of these studies, however, are taking information on the environmental damage costs of the pressure types considered into account. This study is bridging a gap between environmental indices founded in physical pressures and damage costs founded in welfare economics. The aim of the paper is twofold: first, to demonstrate how to implement the information on environmental damage costs within a DEA based environmental performance index, and second, to estimate these indices at product level by using Danish input-output data and environmental data from 1997.  相似文献

The present article offers a concise theoretical conceptualization and operational analysis of the contribution of innovation to regional development. The latter concepts are closely related to geographical proximity, knowledge diffusion and filters and clustering. Institutional innovation profiles and regional patterns of innovation are two mutually linked, novel conceptual elements in this article. Next to a theoretical framing, the article employs the regional innovation systems concept as a vehicle to analyse institutional innovation profiles. Our case study addresses three Portuguese regions and their institutions, included in a web-based inventory of innovation agencies which offered the foundation for an extensive database. This data-set was analysed by means of a recently developed principal coordinates analysis followed by a Logistic Biplot approach (leading to a Voronoi mapping) to design a systemic typology of innovation structures where each institution is individually represented. There appears to be a significant difference in the regional innovation patterns resulting from the diverse institutional innovation profiles concerned. These profiles appear to be region specific. Our conclusion highlights the main advantages in the use of the method used for policy-makers and business companies.  相似文献

This note discusses topics concerning recent evolutions in financial economics research. It focuses in particular on the progress of quantitative finance and applied economics in the context of the global financial crisis. To this end, I examine various important topics in Economics and Finance and discuss several empirical studies on the statistical properties of macroeconomic and financial data through the application of different econometric methodologies. I analyse their empirical findings and discuss their conclusions.  相似文献

Abstract

The main aim of this paper is to provide a spatial modelling framework for income estimation through the application of a contemporary spatial analysis technique. The application refers to the modelling of mean recorded household income in the area covered by the postcodes of the municipality of Athens in 2001. The main findings suggest that there is a very strong relationship between the proportion of people with a postgraduate qualification (namely, a Master's degree or PhD) and mean household income. Furthermore, there is evidence that this relationship is not stationary across space. This finding allows a better understanding as well as modelling of the main determinants of income in Athens.  相似文献

Abstract

During the last decades the rapid progress in the fields of complex modelling and simulationor in the cognitive and the life sciences was not accompanied by a similar advancement of the socio-economic research tradition itself. Socio-economics as a hybrid field for the complex dynamics of modern societies across their micro-, meso- and macro-levels has still a long way to go in order to reach its full potential. The present article provides a general outline for expanding and advancing socio-economics along four different dimensions which should be able to produce a significant take-off for socio-economic theories, models, methods and mechanisms.  相似文献

Our article aims at understanding the determinants of households’ selective waste-sorting behaviours, based on data from an original survey of 694 individuals in the French Provence–Alpes–Côte d’Azur region. The applied literature focuses mainly on countries with high recycling rates. We focus on a region with the lowest recycling rate in France, a country that recycles less than the European country average. We first apply polychoric principal components analysis to reduce the number of explanatory variables to a set of six factors. In a second step, we use a probit model to estimate the probability of waste sorting as a function of these factors. This model tests several hypotheses emerging from the recent literature on behavioural economics applied to households’ selective sorting. This literature pays particular attention to the social influence on recycling behaviour, which has been studied mostly by sociologists and psychologists. The results of our empirical analysis confirm some of the findings in the literature. However, they also highlight some unique features, such as social influences having a negative impact on recycling. This finding contrasts with most of the literature, which finds a positive relationship of social influence on pro-environmental behaviour.  相似文献

We employ a large scale macroeconometric model to study adjustment problems and long term welfare effects of a Norwegian EU-membership. Accession costs depend significantly on the country's level of GDP, the size of its agricultural sector and tariff and VAT revenues as these elements determine the net membership contribution. Without the transfers, integrating the economy into EU generates a small welfare gain. This result is strongly affected by a long period with under-utilisation of resources. With the net contribution included, we identify a welfare loss. This is especially so if fiscal policy is changed to maintain the public sector budgetary balance.  相似文献

China’s move towards a new normal has been motivated by domestic factors and accelerated by the decline in export opportunities to developed countries. This decline, combined with the knock-on effects of China’s growth adjustments, is disrupting the favourable external environment that made developing countries’ export-led development strategies viable. This paper concentrates on a rebalancing of developing countries’ growth strategies towards a greater weight of household consumption as a potential alternative and discusses three challenges – market size, domestic purchasing power and balance-of-payments constraints. Concentrating on the latter, it analyses changes in sectoral compositions of consumer demand and patterns of international trade. Results point to the risk that a shift in growth strategy causes an import surge. The paper’s findings indicate the scope and speed of required product innovation that would prevent a rebalancing of growth strategies towards a greater role of consumption from running into balance-of-payments constraints.  相似文献

This paper investigates the pattern of inbound tourists' consumption in South Africa, examining four main intercontinental markets and five different tourism goods. The empirical investigation develops an almost ideal demand system (AIDS) model and it extends recent research by allowing tourists to base their spending decision on the real effective price differences between South Africa and their home country. The results show that tourist spending in South Africa is a luxury good, and tourists react normally to a change in the relative price of goods. The cross‐price elasticities suggest that the preferences of different markets influence their view of substitutability and complementary effects between various products in South Africa.  相似文献
