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.     

Testing Multiple Non-Nested Factor Demand Systems

This article explains how to obtain straightforward extensions of the most popular univariate non‐nested statistics, and of the RESET‐test, to a multivariate context and examines how to use these tests to compare alternative factor demand systems. The empirical application involves the classical Berndt–Khaled KLEM data set. A statistically adequate specification is determined for each competing factor demand system. The empirical results are interpreted for each system, the models are compared on the basis of multivariate paired and joint non‐nested procedures and practical indications about what to expect if these tests are applied to alternative factor demand specifications are provided.     

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 theory of storage in the crude oil futures market,the role of financial conditions

This study examines the impacts of inventory and financial instability on the basis of the crude oil market. The results show that, first, the basis rises with inventory, and this effect is higher during low inventory regimes. This validates the theory of storage in the crude oil market. Second, the basis rises with financial instability, and this effect is higher during turbulent regimes. These results warn the oil market participants that, to make decisions based on the basis variation, traditionally known as a signal of scarcity or abundance, the underlying cause of the variation has to be considered.     

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.     

Empirical factor demands and flexible functional forms: a bayesian approach

In this paper we compare classical econometrics, calibration and Bayesian inference in the context of the empirical analysis of factor demands. Our application is based on a popular flexible functional form for the firm's cost function, namely Diewert's Generalized Leontief function, and uses the well-known Berndt and Wood 1947–1971 KLEM data on the US manufacturing sector. We illustrate how the Gibbs sampling methodology can be easily used to calibrate parameter values and elasticities on the basis of previous knowledge from alternative studies on the same data, but with different functional forms. We rely on a system of mixed non-informative diffuse priors for some key parameters and informative tight priors for others. Within the Gibbs sampler, we employ rejection sampling to incorporate parameter restrictions, which are suggested by economic theory but in general rejected by economic data. Our results show that values of those parameters that relate to non-informative priors are almost equal to the standard SUR estimates, whereas differences come out for those parameters to which we have assigned informative priors. Moreover, discrepancies can be appreciated in some crucial parameter estimates obtained with or without rejection sampling.     

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.
