Tax mimicking among local governments: some evidence from Spanish municipalities

The aim of this paper is to study the spatial patterns in the Spanish local tax system. The three most relevant taxes are analyzed: the property tax, the motor vehicle tax and the building activities tax, which jointly represent 80% of the tax revenue at local level in Spain. Using spatial econometrics procedures, three alternative weight specifications to define competitors are explored: contiguity, distance and a combination of economic and geographical characteristics. After carrying out an exploratory spatial analysis, the results of the estimation of spatial lag and spatial error models confirm positive spatial-autocorrelation for the property tax and the building activities tax, with an order of magnitude between 0.3 and 0.5. On the contrary, the motor vehicle tax does not exhibit a significant spatial pattern.     

Selección de proveedores basada en análisis dimensional

This article presents the evaluation of a group of six suppliers for an electromechanical component of hydraulic bombs. The comparison is made by using the dimensional analysis technique and the attributes evaluated were the component´s costs, product quality, post sale service from supplier, product reliability, supplier’s administration and organization and production technology in their production system. In addition, in order to integrate the opinion of several persons in the selection and decision process, the information analysis was done with the aid of a decision group integrated by five persons with responsibilities in the purchase area. The technique is easy to apply and has been widely accepted by its users, who are making its use extensive to other components supplier’s selection process.     

Corporate valuation and social capital: a cross-country analysis

This article analyses the influence of social capital on corporate valuation for a sample of 55 countries over the period 1995–2012. The results suggest that social capital is an important determinant of corporate valuation. Interpersonal trust and civic cooperation enhance corporate valuation, even though other institutional and legal characteristics are considered. Furthermore, our results reveal that corporate valuation increases with the GDP annual growth rate, legal enforcement and the protection of shareholders’ rights, but that it is negatively affected by corruption and protection of creditors’ rights. We also obtain some evidence suggesting that civic cooperation has a greater influence over corporate valuation in poorer countries.     

Designing a forest-energy policy to reduce forest fires in Galicia (Spain): A contingent valuation application

Recent issues of this journal have presented an interesting debate regarding forest fires in Galicia, Spain. This article proposes a forest-energy programme that will contribute to reducing the risk of forest fires in this Atlantic Region of Southern Europe. We apply the contingent valuation method to assess a programme whereby 10% of the electricity produced from coal, fuel oil and gas would be replaced by electricity generated in biomass power plants. The programme would begin implementation in 2005 and it would take 6 years (up to 2010) before we reach the 10% goal. The results show that Galician households are willing to pay a mean of 38 Euros per year. In addition, we have introduced an innovative procedure to detect protest responses related to the payment vehicle in a contingent valuation. Heckman's sample-selection procedure is used to analyse the WTP function.     

Declaraciones institucionales y percepciones individuales sobre la sustentabilidad en escuelas de negocios mexicanas

The objective of this paper is to analyze how business schools of Mexican universities deal with the concept of sustainability as part of their educational task. In order to achieve a comprehensive vision, this study considers the environmental, the social, and the economic components of sustainability. After discussing the conceptual dimensions of education for sustainability, the empirical part of the paper consists of two sections: a content analysis of how official university documents handle the concept of sustainability and a survey of professors’ and students’ perceptions of sustainability. The analysis shows that both professors and students in the Management and Accounting disciplines need to extend their understanding about the economic and environmental aspects of sustainability. The results of this study provide information that can guide the efforts made by institutions of higher learning for training their professors and offering a comprehensive education for their students in all three components of sustainability.     

Which workers get insurance within the firm?

Industry-level time series data suggest that low-skilled workers get less insurance within the firm than high-skilled workers. In particular, wages respond relatively more to productivity shocks in low-skilled industries than high-skilled industries. Our theory is that low-skilled workers get relatively less insurance from their firms because they have relatively lower displacement costs. Under limited commitment, lower displacement costs make the workers' outside options more attractive, and hence decrease the amount of risk sharing sustainable within the firm. Evidence on average displacement costs by industry support the theory's predictions.     

The Impact of Foreign Aid Linked to Infrastructure and Pollution Abatement

This paper studies the macroeconomic effects of foreign aid taking into account environmental quality. We develop a dynamic equilibrium model in which public investments in both infrastructure and pollution abatement can be co‐financed using domestic resources and international aid. We consider untied aid, aid fully tied to either infrastructure or abatement and aid equally tied to both expenditures. We find that when the extent to which agents are affected by environmental problems is taken into account, then, regardless of the chances of substitution between factors, transfers linked to both infrastructure and pollution abatement may be the best welfare‐enhancing alternative.
