Average Monotonic Cooperative Games

A subclass of monotonic transferable utility (T.U.) games is studied: average monotonic games. These games are totally balanced. We prove that the core coincides with both the bargaining set à la Davis and Maschler and the bargaining set à la Mas-Colell. To obtain this result a technique based on reduced games is used.

Income,distance and amenities. An empirical analysis

This paper analyses the income distribution of households in Barcelona metropolitan area. For this purpose we use the monocentric model. As the basic model does not have direct implications for this distribution, we survey the extensions of the model that have been used in empirical literature. One of the most promising ways is to introduce externalities in the decision process; they can result directly from exogenous amenities (given traits of urban area) or be created by other agents’ decisions. We first test the simple model relating income to distance. Then we introduce and test the model with exogenous amenities; recreational areas, transportation systems, health, educational and cultural infrastructure. In the third stage we test the model with spatial effects. We present evidence that any model with spatial effects improves significantly the empirical results.     

Must we choose? European unemployment, American inequality, and the impact of education and labor market institutions

In the last 15 years, two equilibria have arisen in the advanced world. On the one hand, wage dispersion has widened in those countries where unemployment has remained low (with cyclical variations). On the other hand, wherever income inequality has remained unchanged, unemployment has shot upwards. To account for these distinct patterns, we develop a political–economic model showing that, controlling for the skills of the population, the effects of technological and trade shocks (that have affected OECD nations) that are contingent on the institutional rules in place. Economies with generous unemployment allowances adjust through subsidized unemployment. By contrast, low levels of social protection lead to less unemployment but wider wage dispersion. The level of qualifications of the labor force determines the extent of the adjustment for a given institutional arrangement. We derive, in turn, the institutional structure of each country from the political conditions in place at the time of the shock. The empirical part successfully tests the model for the sample of European regions and US states.     

Retail trade and payment innovations in the digital era: a cross-industry and multi-country approach

Abstract

This article introduces a novel approach to payment innovations. It t identifies a cross-industry (retail trade and retail banking) and multi-country (USA, some Western European countries and Japan) approach to the interaction between these industries and the new retail payment systems from the 1970s to the mid 1990s. It documents and discusses the different trajectories that have been seen in the different competitive environments, particularly in regard to payment cards. It also analyses the involvement of bankers and retailers in the evolution of card payment systems and their contribution to the global adoption of bank cards. These processes have occurred within a framework in which sectoral boundaries have taken precedence over the payment alternatives associated with cross-industry solutions.     

The Strategic Social Map of a Nongovernmental Organization

Currently, the traditional states-nation, as far as their social commitments are concerned, are giving way to the nongovernmental organizations (NGO). These organizations have a mission, strategy, and goals different from those organizations looking simply for profits. Nevertheless, NGOs are concerned about using management and information systems at least as good as those used by private companies. Organizations try to develop a social strategy taking their social responsibility as starting point. In this paper, the authors describe how to fix the organization mission, its strategy and goals, and also how to make its action map. A strategy proposal will be described, as well as the way on how to put it into practice. The main goals of this paper is to describe the mission, strategy, and goals of the organization; design its strategic social map; fix the limits of the organization's action; apply the theoretical model to a NGO; and design an information model in order to manage the strategic development. The authors would like to express their gratitude to M. Dolors Celma Benaiges, lecturer at the Escola Universitària del Maresme, Universitat Pompeu Fabra, for her assistance reviewing and translating the paper.     

Activity-based costing methodology for third-party logistics companies

This paper will analyze the main costs that third-party logistics companies are facing and develops an activity-based costing methodology useful for this kind of company. It will examine the most important activities carried out by third-party distributors in both warehousing and transporting activities. However, the focus is mainly on the activity of distributing the product to the final receiver when this final receiver is not the customer of the third-party logistics company.The author is grateful to Gerard Ryan for his invaluable comments on this paper.     

Benchmarking Corporate Social Responsibility within Spanish Companies

In this paper, the authors focus on the influence of corporate social responsibility (CSR) upon business profitability. In order to be capable of working with homogeneous data, the authors’ starting point is to use the criteria defined by PricewaterhouseCoopers’ work on the subject, and published by the Spanish journal Actualidad Económica. In this work, an index was created which assigns between one and five points to the companies depending on the importance given by them to CSR. The CSR measurement published by the Observatorio de la RSE will also be considered. In order to measure companies’ profitability, this paper will take into account their return on equity (ROE) and return on assets (ROA) of 2005 and 2006. The authors’ purpose is to demonstrate that the relationship between CSR and business profitability is neutral.

On the joint effect of technological and management innovations on performance: increasing or diminishing returns?

Most studies on innovation are aimed at covering technological innovation, neglecting other modes of innovation based on non-technological drivers. The latter, referred to as management innovation, consists of the implementation of new management practices, processes or organisational tasks. This work advances knowledge on the topic by exploring the joint effect of simultaneously introducing technological and management innovations on performance. Based on an analysis of 12,563 Spanish firms drawn from CIS data, our findings suggest that firms frequently pursue the simultaneous or joint introduction of both technological and management innovations and that integration impacts positively on a firm’s performance, evidencing an inverted U-shape that suggest positive but diminishing returns. A theoretical framework using the capability-based view embraces the emerging conversation on management innovation issues and its relationship with the well-researched technological one.     

Loss of water availability and stream biodiversity under land abandonment and climate change in a Mediterranean catchment (Olzinelles,NE Spain)

In the north rim of the Mediterranean region, where forest cover is increasing as a result of land abandonment and temperatures are rising as a result of climate change, there is increasing interest for the effects of such changes on the runoff of water courses. This is a paramount issue for the conservation of many freshwater habitats and species. In this work we studied the effects of both an increase in forest cover after depopulation and land abandonment and an increase in temperature on the runoff of a Mediterranean catchment and on the aquatic and semi-aquatic fauna species of the stream (Olzinelles valley, NE Spain). Although in our simulation no decreasing trend in runoff is detected, the monthly runoff-rainfall ratio is now 15% lower than 30 years ago, a fact that may be attributed to a drier period rather than to the small afforestation experienced by the catchment in the last decades. Other factors such as increasing temperatures, changing rainfall patterns and increasing canopy cover are discussed. The observed decrease in the water flow has caused the disappearance of white-clawed crayfish (Austropotamobius pallipes), Mediterranean barbel (Barbus meridionalis), chub (Squalius cephalus), European eel (Anguilla anguilla), and southern water vole (Arvicola sapidus). Our results suggest that in a progressively warmer climate, and especially after land abandonment processes, management of Mediterranean mountain areas should be oriented towards an appropriate distribution of agrarian and forest land-covers in terms of water availability. Down to the stream scale, the pools that keep water throughout the year should be conserved and extended to enhance its potential to maintain aquatic and semi-aquatic species populations.     

New Competences for Crisis Times

In general, people always try to achieve their goals in several aspects of their lives such as the studies, jobs, and leisure time. Unfortunately, goals are not always achieved. Sometimes people simply give up on achieving them, or on other occasions, goals are not achieved completely (later, more costly, and to a lesser extent than desired). The principal objective of the present paper is to identify which variables determine success while people try to achieve their own goals. In order to analyze this fact, the authors will define a sample of university students, taking as a goal their current situation, defining the maximum quality of not staying down or not having more than two subjects left to pass. A questionnaire will be developed in order to identify which variables are more important to achieve goals. Answers from the students will permit one to know the importance given to the different variables by them, as well as how students manage these variables in order to achieve their goals. Moreover, a mathematical model will be used to evaluate what is the influence and relevance of each variable to achieving personal goals.
