Business and Social Reputation: Exploring the Concept and Main Dimensions of Corporate Reputation

Different theoretical approaches highlight the growing relevance of corporate reputation as strategic factor. Among these approaches the arguments of the Resource-Based View are special worthwhile (Grant, 1991, California Management Review 33(3), 114–135; Barney, 1999, Sloan Management Review Spring, 137–145). Nevertheless, this topic poses several methodological problems (Barney et al., 2001), as the unavailability to identify and measure this organizational factor, that is “socially complex” and intangible in its nature. In this work, using the findings of our empirical research on Spanish biotechnology firms, we carry out an identification and measurement of corporate reputation, highlighting its two key components: “business reputation” and “social reputation”.

A Conceptual Framework for the Design of Geo-Collaborative Systems

Geo-collaborative systems address the computational support to situations where people are working in different locations, gathering geographically-related data in the field and sharing knowledge. We propose a conceptual framework identifying the design issues that fundamentally set the stage for eliciting the requirements of geo-collaborative systems. The conceptual framework has five elements: places, teams, tasks, artifacts and geo-referenced knowledge. We also highlight two important relationships between some of these elements: (1) a task-artifact relationship, related with the need to increase the organizational decision making abilities through concerted efforts; and (2) an artifact-knowledge relationship, related with the need to support mechanisms for jointly understanding geo-referenced data. The conceptual framework was applied to the development of a groupware tool aiming to increase the productivity of the geological mapping process followed by a national agency with competence in this area. The paper describes in detail how the conceptual framework influenced the groupware design. The obtained results indicate that the framework can focus the designers on the human aspects of geo-collaboration and guide them through the initial design stages.     

Managing complexity： A problem of chaos in fisheries policy

This work intends to present chaos theory （and dynamical systems such as the theories of complexity）, in terms of interpretation of ecological phenomena. The chaos theory applied in the context of ecological systems, especially in the context of fisheries has allowed the recognition of the relevance of this kind of theories to explain fishing phenomena and fisheries policies. It has permitted new advances in the study of marine systems, contributing to the preservation of fish stocks. This paper deals with the way how to manage fisheries taking chaos in account of the problem.     

Access to Bottleneck Inputs under Oligopoly: A Prisoners' Dilemma?

We analyze the incentives of vertically integrated oligopolists to concede access to their bottleneck inputs to an entrant in the downstream market. First, two vertically integrated incumbents make access price offers to an entrant that chooses which one to accept, if any. Second, firms compete on Salop's circle. The firms may be asymmetrically located on the circle, to reflect differences in consumer shares. For some levels of asymmetry, the incumbents face a prisoners' dilemma with respect to conceding access to their bottleneck inputs. Entry by a downstream firm may lead to lower retail prices. However, entry may also lead to higher retail prices for the access provider and for the entrant. We also consider the cases where there are several incumbents and where the entrant makes the access price offers.     

Quality of schooling and inequality of opportunity in health

This paper explores the role of quality of schooling as a source of inequality of opportunity in health. Substantiating earlier literature that links differences in education to health disparities, the paper uses variation in quality of schooling to test for inequality of opportunity in health. Analysis of the 1958 NCDS cohort exploits the variation in type and quality of schools generated by the comprehensive schooling reforms in England and Wales. The analysis provides evidence of a statistically significant and economically sizable association between some dimensions of quality of education and a range of health and health-related outcomes. For some outcomes the association persists, over and above the effects of measured ability, social development, academic qualifications and adult socioeconomic status and lifestyle.     

Networks of queues with infinite servers in each node applied to the management of a two echelons repair system

After a report of results about infinite servers queues, essentially on its busy period, a model is built, using networks of queues with infinite servers in each node, to study a two echelons repair system for example of a fleet of aircraft, shipping or trucks. The customers are the failures, and their service time is the time that goes from the instant at which they occur till they are completely repaired. The failing repairs occur in a base or in a remote station. The whole failures detected in the base are repaired there. Some of the failures detected in the station are repaired there and the others in the base. The results referred above allow the determination of a two echelons repair system performance measures. In this application, models of Carrillo （1991） and Ferreira （1996） are considered, improved and completed. The theory is illustrated with a numerical example.     

Agency-Theory and Internal-Labor-Market Explanations of Bonus Payments: Empirical Evidence from Spanish Firms

This paper combines agency theory and internal-labor-market theories to explain the determinants of bonus payments among a large sample of top and middle managers from Spanish firms. A distinction is made between the decision whether to pay bonus or not and the size of the bonus. The empirical evidence confirms that the two decisions are determined by different factors. The results of the analysis show a trade-off between short-term and long-term incentives (bonuses and promotion opportunities) as well as differences in the pattern of compensation policies across economic sectors and functional areas inside the firm.     

Accruals quality and corporate cash holdings

This Work Uses Panel Data For Firms Listed In The Spanish Stock Exchange Over The Period From 1995 To 2001 To Analyse The Effect Of Accounting Quality On Cash Holdings. The Results Show That Firms With Good Accruals Quality Hold Lower Cash Levels Than Firms With Poor Accruals Quality. This Finding Suggests That The Quality Of Accounting Information May Reduce The Negative Effects Of Information Asymmetries And Adverse Selection Costs, Allowing Firms To Reduce Their Level Of Corporate Cash Holdings. The Results Also Show That Cash Holdings Decrease When Firms Increase Their Use Of Bank Debt And In The Presence Of Cash Substitutes. In Contrast With This, Firms With Higher Cash Flow Hold Higher Levels Of Cash.     

The consumer loss of the minimum duration for mobile telephone calls

This article estimates price elasticities of demand for the duration of mobile telephone calls for Portugal, as well as the monetary loss per consumer of the existence of a minimum duration of calls. The demand for the duration of calls is estimated using a Tobit model for panel data with individual random effects. The elasticity of demand is found to be small and to vary across firms. At current prices, the average duration of calls ranges between 101 and 109 s, while the estimated average length of calls without minimum duration ranges between 63 and 66 s. Hence, the existence of a minimum duration for calls results in a monetary loss of 35–40% of the average invoice.
