The raw material basis of global value chains: allocating environmental responsibility based on value generation

A new approach to allocate environmental responsibility, the ‘value added-based responsibility’ allocation, is presented in this article. This metric allocates total environmental pressures occurring along an international supply chain to the participating sectors and countries according to the share of value added they generate within that specific supply chain. We show that – due to their position in global value chains – certain sectors (e.g. services) and countries (e.g. Germany) receive significantly greater responsibility compared to other allocation approaches. This adds a new perspective to the discussions concerning a fair distribution of mitigation costs among nations, companies and consumers.     

Carbon taxes and the double dividend hypothesis in a recursive-dynamic CGE model for Spain

A carbon tax is potentially a policy that can reduce CO₂ emissions and mitigate climate risks, at lowest economy-wide costs. We develop a dynamic CGE model for Spain to assess the economic and environmental effects of a carbon tax, and test the double dividend (DD) hypothesis. We simulate the impact of three carbon taxes: €10, €20 and €30 per ton of CO₂. For each tax, four ‘revenue recycling’ scenarios are examined: a reduction of taxes on capital, on labor, on value-added tax, and a scenario in which revenues are not recycled. We find a DD for taxes of €10/ton and lower, within five to seven years of implementation. We estimate an annual CO₂ emissions reduction of around 10% with this tax. Under some circumstances, the DD can be achieved for a tax of €20/ton. In any case, recycling revenues to cut pre-existing taxes reduces costs of imposing carbon taxes.     

An application of co-word analysis and bibliometric maps for detecting the most highlighting themes in the consumer behaviour research from a longitudinal perspective

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield, concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR. It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future research could lead.     

An approximation method to derive confidence intervals for quantiles with some applications

Standard jackknife confidence intervals for a quantile Q _y (β) are usually preferred to confidence intervals based on analytical variance estimators due to their operational simplicity. However, the standard jackknife confidence intervals can give undesirable coverage probabilities for small samples sizes and large or small values of β. In this paper confidence intervals for a population quantile based on several existing estimators of a quantile are derived. These intervals are based on an approximation for the cumulative distribution function of a studentized quantile estimator. Confidence intervals are empirically evaluated by using real data and some applications are illustrated. Results derived from simulation studies show that proposed confidence intervals are narrower than confidence intervals based on the standard jackknife technique, which assumes normal approximation. Proposed confidence intervals also achieve coverage probabilities above to their nominal level. This study indicates that the proposed method can be an alternative to the asymptotic confidence intervals, which can be unknown in practice, and the standard jackknife confidence intervals, which can have poor coverage probabilities and give wider intervals.     

Social capital as a distinctive feature of Social Economy firms

In recent years, the growing importance in developed countries of the Social Economy sector and the contribution of social capital to regional economic development are being studied in depth. Linking these two fields of research, the aim of the present work is to analyse the social capital endowments of Social Economy firms in comparison to those in traditional profit-maximizing firms. To do so, a literature review will be firstly carried out to clarify both the concept of social capital and, more specifically, its relation with entrepreneurship and social enterprises. In the empirical section, the social capital endowments both of social firms (cooperatives and owned-worker enterprises) and traditional firms are compared using data from two surveys conducted in Andalusia, a lagged Spanish region with long tradition in the Social Economy sector. Results show that social capital endowments measured through cooperation agreements and company links with local suppliers and costumers are higher in cooperatives and worker-owned companies. Therefore, Andalusian authorities must continue with its support policy to these enterprises as a mean to reinforce the regional economic development.     

A qualitative approach to the challenges for women in management: are they really starting in the 21st century?

Traditionally, the role of women in business responsibility jobs has provided extensive and much discussed issues. Almost 20?years ago research on WIB was very rich. Some discussions surrounding women in business included, for instance: learning about their situation at work, their strong and weak management capabilities and possible setbacks to their promotion and consolidation in positions of responsibility. In any case, it did seem that conciliation between family and work lives, in general, was a setback for most women. By the beginning of 21st century the work of Leonard (Women??s Stud Int Forum 24:67?C78, 2001) analyzed the state-of-the-art, concluding that not much had changed in terms of the challenges faced by women. Therefore, it may seem appropriate, to readdress the situation for women in management as this new century reaches its first decade. This paper takes as a reference the context of an occidental and developed country such as Spain. We develop a multi-case study which allows us to (i) analyze the opinion of a group of women and men who work in high and intermediate management positions, (ii) defend the suitability to overcome the differences between men and women and (iii) admit the consideration of different female profiles. In such cases, firms may take several advantages stemming from both gender and personal characteristics.     

Does mandatory disclosure affect subprime lending to minority neighborhoods?

We examine changes in lending behavior in response to the Federal Reserve??s requirement for disclosure of loan pricing information implemented in 2004 for two broad types of lenders, depository and nondepository institutions. We find that although subprime approval rates generally increased after 2004 as the housing market boomed, there was nonetheless a reduction in subprime approval rates to minority neighborhoods following implementation of the pricing disclosure requirement. We also find that the effect of the pricing disclosure requirement on subprime approval rates was stronger for depository institutions than for nondepository institutions. Moreover, depository institutions with good reviews from regulators for effectively serving the financing needs of local communities are less likely to issue higher-priced subprime loans.     

Union games: technological unemployment

Summary. Given a production economy, we define union games by considering strategic behavior of the suppliers of factors. We refer to the Nash equilibria of this game as union equilibria. We analyze situations where the unemployment of factors is supported as a union equilibrium. The degree of unemployment depends on technological conditions. This allows us to model a source of unemployment which differs from the usual sources provided in the literature. We state a limit result that demonstrates that, as the market power of unions decreases, the corresponding sequence of union equilibria converges to the Walrasian equilibrium, that is, to full employment of factors. We also provide some examples that illustrate the main results.Received: 21 October 2004, Revised: 14 December 2004, JEL Classification Numbers: D51, C72. Correspondence to: Emma Moreno-GarcíaE.

Buy-price English auction

Consider an English auction for a single object in which there is an option for a bidder to guarantee a purchase at a seller-specified buy price b at any time. We show that there exist and (), such that a bidder purchases at the buy price immediately if his valuation v is no less than or and at least one other bidder is participating in the auction. If , he purchases at the buy price once the current bid reaches a strategically chosen threshold price. A properly set buy price increases expected social welfare and the expected utility of each agent when either buyers or seller are risk-averse.
