Information and communication technology in retailing: A cross-industry comparison

Information technology (IT) may represent a source of competitive advantage for businesses in general and for retailers in particular. However, there is debate in the literature over the usefulness of investing in technology. This paper aims at analyzing the relationship between consumers’ perception on the use of information and communication technology by the retailer and consumer satisfaction with retailer technologies. Results support the need to restrict the investment in IT to what is strictly necessary, although there are significant differences according to retailer activity.     

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.

Voting in small networks with cross-pressure

We present a model of participation in elections in small networks, in which citizens suffer from cross-pressures if voting against the alternative preferred by some of their social contacts. We analyze how the existence of cross-pressures may shape voting decisions, and so, political outcomes; and how parties may exploit this effect to their interest. We characterize the strong perfect equilibria of the game and show that, in equilibrium, the social network determines which party wins the election. We also show that to dispose of the citizens better connected in the network with the other faction is not a guarantee to win the election.      

The State in Court: the economic effects of fee-shifting rules in Spain when suing the government

Following the recent public debate concerning the situation of the Judicial system in Spain, the paper analyses the special position of the State in Court, essentially with reference to suits brought by individuals against the State before Spanish first instance Courts, although international Courts are touched as well. The analysis focuses on the incentives to litigate and to settle in a dispute with the State, focusing on the State’s special procedural rules and the fee-shifting rules applied in the Spanish Justice system. The asymmetries in favor of the State reduce the incentives to litigate against the State, but also reduce the settlement range in order to achieve out-of-Court settlements.     

Strategies developed by leading EU agrifood cooperatives in their growth models

The objective of this article is to identify the factors that have brought about the greatest degree of competitiveness in some of the principal agrifood cooperative groups in the European Union (EU), using pertinent case studies from a range of sectors including the dairy, meat and fruit and vegetable sectors from three EU member states: Holland, Ireland and Denmark. With this purpose in mind, seven cases were identified for inclusion: Kerry Group, the Irish Dairy Board, Arla Foods, The Greenery BV, Danish Crown, Agrifirm and DLG. The article identifies the main barriers and problems faced by this type of cooperative and shows the strategies developed by leading cooperatives in their sector within the current comparative context and familiarizes readers with the different growth models these cooperatives use to achieve and maintain their market standing.     

Unifying exotic option closed formulas

This paper aims to unify exotic option closed formulas by generalizing a large class of existing formulas and by setting a framework that allows for further generalizations. The formula presented covers options from the plain vanilla to most, if not all, mountain range exotic options and is developed in a multi-asset, multi-currency Black?CScholes model with time dependent parameters. It particular, it focuses on payoffs that depend on the distributions of the underlyings prices at multiple but set time horizons. The general formula not only covers existing cases but also enables the combination of diverse features from different types of exotic options. It also creates implicitly a language to describe payoffs that can be used in industrial applications to decouple the functions of payoff definition from pricing functions. Examples of several exotic options are presented, benchmarking the closed formulas?? performance against Monte Carlo simulations. Results show a consistent over performance of the closed formula reducing calculation time by double digit factors.     

The Main Determinants of the Use of the Cost Accounting System in Portuguese Local Government

Abstract: This paper explores the main determinants of the use of the cost accounting system (CAS) in Portuguese local government (PLG). Regression analysis is used to study the fit of a model of accounting changes in PLG, focused on cost accounting systems oriented to activities and outputs. Based on survey data gathered from PLG, we have found that the use of information in decision‐making and external reporting is still a mirage. We obtain evidence about the influence of the internal organizational context (especially the lack of support and difficulties in the CAS implementation) in the use for internal purposes, while the institutional environment (like external pressures to implement the CAS) appears to be more deterministic of the external use. Results strengthen the function of external reporting to legitimate the organization's activities to external stakeholders. On the other hand, some control variables (like political competition, usefulness and experience) also evidence some explanatory power in the model. Some mixed results were found that appeal to further research in the future. Our empirical results contribute to understand the importance of interconnecting the contingency and institutional approaches to gain a clear picture of cost accounting changes in the public sector.     

Twin Crises in Emerging Markets: The Role of Liability Dollarization and Imperfect Competition in Banking

Currency crises in emerging markets have been accompanied by banking crises, with concentration in the market for bank credit increasing after large devaluations. This paper examines how the presence of imperfect competition and liability dollarization in banking shapes the real effects of the just mentioned twin crises. An important gap in the theoretical literature is filled, by being the first paper to provide a model of twin crises in the presence of imperfect competition in banking, and the changes in market structure that occur in the aftermath of crises. Doing so, the analysis is able to reveal that currency devaluations generate more severe twin crises in economies with less competitive banking sectors. This result is consistent with the empirical evidence on the concentration‐fragility view, and it unveils the importance of prudential regulation that focuses on the market structure in banking.     

Fuzzy Negotiation Solutions of n-Person Cooperative Games by Knowledge Engineering in Bargaining

A model for negotiation is developed upon the basis of a previous model called Fuzzy Negotiation Solution by Knowledge Engineering. The new model, called Compensatory Negotiation Solution by Knowledge Engineering and FNSKE are based on the combination of knowledge of experts in negotiation, rather than on classical notions of rationality. The experts in negotiation present four propositions in a non-mathematical way and with a natural language, according to the theory of Knowledge Engineering. In the CNSKE model, knowledge is represented through logic predicates, and the calculations are made using the Compensatory Fuzzy Logic system. CFL is a system whose operators satisfy the axioms of Utility. The CFL operators, especially because of the compensation property, are more adequate than the norm and co-norm’s operators to model human decision-making, according to empirical results. The Good Deal Index in CNSKE is statistically estimated from the GDI in FNSKE. This is a quantitative index, which provides the solution concept. The fuzzy function f(C) represents the likelihood the players of a coalition C to reach an agreement into this coalition. Counterpart Convenience Indexes 1, 2 allow each player to select the best coalition for negotiation. The advantage of CNSKE over FNSKE is that the idempotency of conjunction and disjunction operators give every membership function -obtained from the predicates- the possibility to be interpreted by itself. Hence, the truth-values of the CNSKE membership functions can be semantically interpreted. In addition, CNSKE can be easily applied to solve real negotiation problems.     

Transforming Human Resource Management Systems to Cope with Diversity

The purpose of this study is to examine how workgroup diversity can be managed through specific strategic human resource management systems. Our review shows that ‘affirmative action’ and traditional ‘diversity management’ approaches have failed to simultaneously achieve business and social justice outcomes of diversity. As previous literature has shown, the benefits of diversity cannot be achieved with isolated interventions. To the contrary, a complete organizational culture change is required, in order to promote appreciation of individual differences. The paper contributes to this discussion by exploring the implications of this change for human resource management, and explaining how the systems of practices should be changed when they are directed to diverse groups. The model designed to test this notion includes: (1) demographic and human capital diversity as independent variables, (2) group performance (measured as innovation outcomes) as the dependent variable and, (3) the orientation of the strategic human resource management system as a potential moderator of this relationship. The main conclusion of the empirical analysis developed is that different patterns of human resource management practices can be used, depending on the type of diversity that the organization faces, and the specific effects that it wishes to manage. Concretely, three alternative management systems are identified in this paper, with different moderating effects. This result has interesting implications for human resource management professionals, explained in the last section. The limitations of this study are also discussed, as well as some issues that future research in this field should address.
