De Ginebra a San José: las normas de la OIT y el sistema interamericano de protección de los derechos humanos

Los autores analizan cómo los órganos interamericanos de derechos humanos utilizan las normas de la OIT como referencia en asuntos de libertad sindical y de asociación y derechos de los pueblos indígenas. Exponen los límites del método por litispendencia y competencia y analizan cómo estas normas han influido en la reciente jurisprudencia interamericana sobre ciertos derechos económicos, sociales y culturales. Defienden la conveniencia de este método de referencias cruzadas, que permite a los órganos interamericanos basarse en interpretaciones autorizadas, al tiempo que aumenta la credibilidad, la legitimidad normativa y la universalidad de sus decisiones.     

Transaction Costs,Option Prices,and Model Risk in Fair Value Accounting

This paper examines the reliability of option fair value estimates in the presence of transaction costs. The Black Scholes Merton (BSM) framework assumes zero transaction costs and thus might not provide a reasonable approximation in this context. We investigate the model adjustments companies make to their BSM models to deal with these transaction costs. We specifically examine Employee Stock Option (ESO) plans listed on the French stock exchange, as detailed disclosure on modeling is available for these ESOs. Our analysis questions the reliability of these model adjustments, especially their bias and the extent to which they provide a faithful representation of option fair values. Holding parameter values constant, we find that the model adjustments lead to a median understatement of 52% compared to the BSM model price, higher than the discount we observe for the opportunistic determination of model parameters (below 20%). The paper contributes to the fair value literature by highlighting model risk in the fair valuation of options. This model risk stems from assumptions made about the size of transaction costs and complements the notion of parameter risk analyzed in previous literature. As a result, the model itself might be a possible channel for fair value management.     

Endogenous growth and environmental policy: are the processes of growth and tertiarization in developed economies reversible?

The starting point for this article is the idea put forward by Gadrey (2008, 2010) that environmental problems and a policy of addressing them by introducing an environmental tax could trigger economic contraction and downscaling and a shrinking of the service sector in developed economies. The purpose of this article is to test these hypotheses using an evolutionary simulation model. To this end, we use a model of endogenous growth and structural change into which an environmental dimension is incorporated. The results of our simulations certainly reveal structural change within service industries but no change in the distribution of employment between services and manufacturing. Furthermore, we show that the environmentally desirable stagnation of labor productivity in the capital goods sector is compatible with a largely positive growth trend in the economy as a whole, with the development of knowledge-intensive business services apparently able partially to offset the stagnation of productivity in the capital goods sector. We conclude by emphasizing the need for environmental innovation in service activities and cast doubt on the long-term effectiveness of an environmental tax in the fight against pollution.     

Worker Information and Firm Disclosure Analysis on French Linked Employer–Employee Data

Information disclosure requirements significantly increased in French listed companies in the early 2000s, converging toward the U.S./U.K. stock market standards. We investigate the consequences of this process regarding worker information: does more information for shareholders mean more information for workers? Our empirical analysis takes advantage of a French establishment survey that generates linked “employer–employee” data at two points in time, 1998 and 2004. Our results show that worker information has improved in listed companies as an externality of the financialization process. We find, however, that this extra information is only partially correlated with greater employee satisfaction.     

The economics of the smart card industry: Towards coopetitive strategies

This article uses an explorative case study of the smart card industry where ‘coopetition’ is to be found. We show that the nature of interaction between smart card actors, dealing with industry and market conditions that create a very complex competitive landscape, constitutes a mix of competition and cooperation. Here, we assume that the paradoxical aspect of competition and cooperation [Quinn, R.E. and Cameron, K.S. (1988) Paradox and Transformation. Cambridge, MA: Ballinger] can be juxtaposed in order to understand the strategic phenomena characterizing actors' interactions. Actors cooperate in some activities and compete on other ones. Such strategic behaviour is called coopetitive strategy, which is increasingly adopted by high-tech industry players.     

Measuring innovation in a ‘low-tech’ service industry: the case of the Dutch hospitality industry

This article presents the findings of a survey among 613 firms in the Dutch hospitality industry adopting a demarcation perspective. The paper illustrates that innovation in this service industry is much higher and more varied than regularly reported. It further indicates that innovation activities in ‘low-tech industries’ can be in place with less formalized forms of (service) innovation management. Finally, it is shown that a higher innovation intensity is associated with better firm performance. Based on this, some implications for managing innovation in the hospitality industry are discussed. Finally, some fundamental issues in the measurement of service innovation are raised.     

The performance effects of major workforce reductions: longitudinal evidence from North America

This paper investigates the performance effects of major job cuts.1 1 Like Wayhan and Werner (2000 Wayhan, V. and Werner, S. 2000. The Impact of Workforce Reductions on Financial Performance: A Longitudinal Perspective. Journal of Management, 26: 341–63. [Crossref] , [Google Scholar]), we interchangeably use the expressions ‘workforce reduction’ and ‘job cuts’ instead of the broad concept of ‘downsizing’ which is subject to multiple confusing definitions (DeWitt, 1998 DeWitt, R.L. 1998. Firm Industry and Strategy Influences on Choice of Downsizing Approach. Strategic Management Journal, 19: 59–79.  [Google Scholar]). Using data from Compustat S&P database, we examined the longitudinal impact of workforce reductions on labour productivity and operational indebtedness of 239 US and Canadian companies. Repeated measures analysis showed that firms that substantially cut jobs failed to improve their labour productivity and their operational indebtedness. Then, taken a step further, statistical analysis surprisingly revealed that firms that cut the highest proportions of their workforce had a significant deterioration of their operational indebtedness and a non-significant change of their labour productivity. These results call into question the economic legitimacy of major workforce reductions increasingly institutionalized to the detriment of the strategic approach of HRM.     

Political dependence,social scrutiny,and corporate philanthropy: Evidence from disaster relief

This study explores why and how firms respond to social demands through philanthropic giving in the context of a severe natural disaster. Drawing on Marquis and Qian's organizational response model to government signals, we integrate resource dependence theory and institutional theory to build a two‐step model of organizational response to social needs, in situations of disaster relief. We argue that firms depending more on the government for support are more likely to donate in disaster relief, while firms who receive more scrutiny from the government and the general public and firms having more slack resources are likely to donate more. Evidence from Chinese listed companies' donations to the 2008 Sichuan earthquake largely supports our predictions. This study provides a more precise understanding of the corporate philanthropic decision process, decoupling the drivers of philanthropic giving, and those determining the amount given. Theoretical and practical implications are suggested.     

WELFARE AS EQUITY EQUIVALENTS

Equity (or, its counterpart, inequity) plays a fundamental role in the evaluation of social welfare in different dimensions. In this paper, we revisit the concept of inequity – in the sense of unequal distributions – across individuals, time, and states of the world using a unified framework that generalizes the standard expected discounted utilitarianism approach. We propose a general measure of welfare as equity equivalents and a corresponding inequity index. We show that allowing for different attitudes toward inequity across different dimensions covers a scope of possible inequity preferences with different interpretations. We then prove that the order of aggregation across the different dimensions matters for welfare evaluations. Finally, we show that many of the welfare-theoretical approaches recently developed in the literature can be interpreted as special cases of this general framework.     

The effectiveness of a permaculture education project in Butula,Kenya

In the 1980s, agricultural development organizations began promoting permaculture, an agroecological approach that emphasizes local autonomy, through training programmes in the developing world. Few assessments have measured the effectiveness of such projects. Here we surveyed and interviewed small-scale farmers to assess the perceived impacts of a Canadian permaculture non-governmental organization’s (NGO) project in Butula, Western Kenya. Two types of projects are evaluated and compared: community projects (CPs) at six primary schools, and an intensive two-week permaculture design certification (PDC) programme. Our results suggest that both PDC and CP participants felt that they had benefited from the projects. However, PDC participants developed a more comprehensive understanding of permaculture, felt empowered and frequently related permaculture to their own traditional cultural values whereas CP participants often misunderstood permaculture, felt frustrated by the limited immediate economic benefits and frequently contrasted permaculture against traditional cultural values. These differences may have occurred because CP participants had fewer opportunities to interact directly with the permaculture teachers, to ask questions, or to clarify points of uncertainty. This study emphasizes the importance of direct, reciprocal communication between NGOs and project participants for fostering feelings of autonomy and competence, thereby strengthening resilient agroecological systems.
