Evidence of different models of socially responsible HRM in Europe

Socially responsible human resource management (SR‐HRM) is becoming increasingly important for academics and managers. The interface between HRM and corporate social responsibility (CSR) is the subject of analysis in this article. It adopts a contextual perspective to analyze whether the institutional context influences the implementation of socially responsible HRM (SR‐HRM). Considering the differences in the national institutional contexts across Europe, this study explores the different models of SR‐HRM in that region. The research is focused on a sample of 153 companies headquartered in Germany, Spain, Sweden, and the United Kingdom. The findings evidence the influence exerted by the national institutional context on the implementation of SR‐HRM. Differences among country clusters suggest the existence of different models of SR‐HRM in Europe. However, these models do not correspond to the blocks on HRM or on CSR identified by the literature but instead provide a novel categorization.     

Distinctive Features of Environmental Innovators: An Econometric Analysis

This paper analyzes the main determinants influencing environmental innovators (i.e. firms developing or adopting environmental innovations) in Spain with respect to non‐environmental innovators. Similarly to other contributions in the literature, our results show that Spanish environmental innovators respond to regulatory stimulus in the form of demand‐pull and technology‐push instruments. They have a high internal technological capability and combine internal and external information sources, mostly in cooperation with knowledge institutions. Environmental innovators are more concentrated in mature, traditionally highly polluting sectors, but new firms are not more environmentally innovative than incumbents. Most importantly, in contrast to other environmental innovation studies, mostly carried out in a German context, we have not found evidence of a market pull from either the domestic or international markets. Furthermore, cost savings are not found to be a distinctive driver for environmental innovators. These differential results are possibly related to the special features of Spain regarding its national innovation system and the degree of stringency of environmental regulation and environmental consciousness of its consumers.

Managerial Problem-Solving Styles: A Cross-Cultural Study

ABSTRACT

The literature suggests that North American business-people differ from their Latin American counterparts with respect to specific behavioral traits. Our particular interest is in problem solving and in effecting changes in behavior to achieve better problem-solving capability. The purpose of the present study is to assess whether there are differences in problem-solving styles between two culturally different groups of managers registered in MBA Programs: Anglo American and Latin American. Using Kolb's (1984 2006) Learning Style Inventory, it was found that Anglo American managers tended to be relatively action-oriented, “Convergers” (they emphasize decision-making and use deductive reasoning), while Latin American managers tended to be reflection-oriented, “Assimilators” (they emphasize planning and like to create models in their analyses) in their problem-solving styles. The positive and negative aspects of each style are discussed and suggestions for improved decision-making are offered.

RESUMEN. La literatura sugiere que los empresarios norteamericanos difieren de sus contrapartes latinoamericanos, en lo que atañe a ciertos trazos comportamentales específicos. Nuestro interés particular se orienta a la solución de problemas e implementación de cambios comportamentales, con el propósito de adquirir habilidades específicas para la solución de problemas. El propósito de este estudio es evaluar si existen diferencias entre los estilos empleados para solucionar problemas entre diferentes grupos culturales de gerentes matriculados en Programas MBA angloamericanos y latinoamericanos. Usando el sistema de estilos de Kolb (1984 2006) denominado Learning Style Inventory, descubrimos que los gerentes angloamericanos tienden a orientarse con bastante frecuencia en la acción, los llamados ‘Convergentes’ (que hacen hincapié en la toma de decisiones y el uso del razonamiento deductivo), mientras que los gerentes latinoamericanos tienden a volcarse a la reflexión, los llamados ‘Asimiladores’ (que hacen hincapié enplanear y les gusta crear modelos en sus análisis), como característica de sus estilos para solucionar problemas. Discutimos los aspectos positivo y negativo de cada estilo, y hacemos sugerencias para mejorar la toma de decisión.

RESUMO. A literatura sugere que os homens de negócios norte-americanos diferem de seus colegas latino-americanos em traços comportamentais específicos. Nosso interesse particular recai sobre a resolução de problemas e a introdução de mudanças de comportamento para obter uma melhor capacidade de resolução de problemas. O objetivo deste estudo é avaliar se existem diferenças nos estilos de resolução de problemas de dois grupos culturalmente diferentes de gerentes matriculados em cursos de MBA: anglo-americanos e latino-americanos. Utilizando o inventário LSI (learning style inventory) de Kolb (1984 2006), constatou-se que os gerentes anglo-americanos tendiam a ser relativamente orientados para a ação, “convergentes” (eles enfatizam a tomada de decisões e o raciocínio dedutivo), enquanto os gerentes latinoamericanos tendiam a ser orientados para a reflexão, “assimiladores” (eles enfatizam o planejamento e gostam de criar modelos em suas análises) em seus estilos de resolução de problemas. Os aspectos positivos e negativos de cada estilo são discutidos, e sugestões para melhorar a tomada de decisões são oferecidas.     

Note on the applicability of the VCG mechanism to capacitated assignment problems and extensions

For the allocation of heterogeneous items, it is known that the buyers-are-substitutes condition is necessary and sufficient to ensure that a pricing equilibrium can yield the same allocation and payments as the VCG mechanism. Furthermore, concavity of the corresponding transferable utility TU-game guarantees that this VCG outcome can also be achieved by an ascending price auction. We show that concavity, and hence the buyers-are-substitutes condition, holds for the TU-game of the assignment problem with general capacities. Therefore, the VCG mechanism is supported by a pricing equilibrium which can also be achieved by an ascending auction. We also show that the buyers-are-substitutes condition, and hence concavity, does not hold anymore for very natural and straightforward extensions of this problem. This shows that the necessity of the substitutes property is a considerable restriction on the applicability of the VCG mechanism.     

A methodology to assess the current situation in irrigated agriculture: An application to the village of Tauste (Spain)

Abstract

This paper presents a simple weighted goal programming model which can be used to predict the current allocation of agricultural enterprises in a particular geographical area. Moreover, it also shows how the approach proposed can be integrated into a multiobjective framework to measure the opportunity cost of maintaining the current situation in terms of several criteria relevant from a private and a public perspective. In this way, the opportunity cost of sustaining the current allocation of agricultural enterprises in the irrigated lands of Tauste (Spain) is assessed in terms of gross margin, employment, seasonal labour and water consumption.     

A Note on Distributive Equity and Social Efficiency

This note proposes a social welfare function (SWF) where most functions, such as the Benthamite or the Rawlsian functions, found in the literature can be considered particular cases. Moreover, the SWF propounded let us obtain compromises or balances between the welfare criteria of social efficiency and distributive equity. The level of compromise or balance is established with the help of a simple and operational parameter.     

A Test of Two Skew Models to Explain Cooperative Breeding

Synopsis Two competing models, reproductive skew and skew selection, have been constructed to explain the evolution of cooperation among unrelated breeders. Reproductive skew is a trade-off model that assumes breeding occurs under scarce resource conditions. One breeder gains units of fecundity at the expense of other breeders during aggressive, altruistic or tug-of-war transactions. After joining, the distribution of fecundity among breeders shifts from symmetrical to asymmetrical. In contrast, skew selection is a surplus model that assumes breeding occurs during a springtime glut. Skew selection assumes that fecundity among breeders is initially asymmetrical and that joining reduces the asymmetry of fecundity. This paper reports findings from a breeding experiment on the fire ant, Solenopsis invicta, which supported skew selection rather than reproductive skew. Joining was a win-win strategy for alpha and beta breeders; beta breeders gained within-group survival benefits; alpha breeders gained between-group survival benefits. In summary, skew selection extends Darwin’s theory of natural selection by revealing the self-interested core of cooperative breeding.      

Organizational Culture, Individual Differences and the Participation System in Cooperativism of Associated Workers in Andalusia, Spain

From a psychosocial perspective, we have attempted to identify the characteristics of the democratic systems of a sample of 36 Andalusian cooperatives of associated workers. In this study it has become evident that those who participate the least in the governments of their organizations are the workers and those with less education. Thus, there is a high degree of association between participation in the governing of the cooperative and the development within it of an appropriate organizational culture. The results of this study have allowed us to empirically deconstruct the concept of cooperative democracy, and this process may have an effect on the improvement of human resource administration in this type of organization.
