In literature and R&D organizations alike, project success consists in minimizing the deviations from set targets in terms of quality, cost and time. The main management task is to execute and monitor progress to reduce risks – assuming that project attributes are known, necessary resources can be estimated and a reasonable time table can be agreed upon. In such a context, evaluating project success is easy. However, in an innovative context, setting project targets initially is difficult and the contributions of the projects sometimes are of an unexpected nature. This paper investigates if projects can be evaluated in terms of how they contribute to the building of innovative capabilities of the firm instead of independently. Based on a case study at the Régie Autonome des Transports Parisians and the theoretical framework of innovation fields, a framework for evaluating projects from an additional perspective is proposed. Based on the following four criteria: financial resources, the development of a structured, refined and expanded strategic vision, developed competences (with related suppliers) and identification of knowledge gaps (occasionally with related partners for knowledge production), this framework shows how seemingly failed R&D projects can instead be considered as invaluable to the overall innovation process. 相似文献

Considering that the level of the association between stock returns and accounting earnings provides a measure of the extent to which earnings summarize the information which is useful for firm valuation, this paper analyses the contemporaneous association between stock returns and earnings changes or earnings level of individual French stocks and portfolios for periods of one, two and five years between 1981 and 1990. The empirical findings are as follows. (a) Stock returns are more linked to earnings changes than to earnings levels indicating that earnings provide more information about changes in firm value than about firm value. (b) Earnings prepared in accordance with the French accounting principles are not less value-relevant than those prepared in accordance with US or UK GAAP. (c) A cross-sectionally and time-aggregated data procedure provides a large increase in the explanatory power of earnings for returns which is consistent with a noise-in-earnings effect probably induced by accounting measurement and valuation principles and with a recognition lag effect due to the fact that value-relevant events are not integrated into earnings exactly when they occur. These two effects are shown to be the major causes of the low association between earnings and returns generally observed in studies based on short period data for individual stocks. 相似文献

AbstractThe present research examines the relationships between progressive HRM practices and the organizational citizenship behaviors (OCB) of professional employees. Drawing on recent HRM literature, our research model includes a perceived organizational support (POS)-commitment mediation hypothesis. Taking into account previous studies on professional employees, a job satisfaction-commitment pathway is also integrated. We tested both mediational pathways as part of a single structural equation model using a sample of 329 professional employees. Our results show that the relationship between recognition and OCB is mediated by the POS-commitment pathway, while the relationships between fairness of rewards, skills development and OCB are mediated by the job satisfaction-commitment pathway. The specificities of the HRM of professional employees related to their multiple cognitive orientations are discussed. 相似文献

This article tests and extends the evolutionary theory of household consumption behavior, which is an alternative to neoclassical theory. Evolutionary economists offer novel approaches to the analysis of consumption behavior that emphasize the major role of learning in the evolution of consumer preferences and wants. As a possible inspiration for further progress in evolutionary thought, this paper examines the idea of consumer learning by studying the nature of what consumers should learn in the context of ‘novelty’. Our empirical results regarding novelty during the learning process show that consumers learn the ‘new characteristics’ of consumer goods, contrary to the Lancasterian approach, which suggests that the characteristics space of goods is fixed. We show that during the process of consumption, ‘consumer learning’ extends the characteristics space of consumer goods; this phenomenon is far from negligible and differs across product types. Moreover, our results show that the emergence of new characteristics cannot be modeled as a Poisson process because these new characteristics exhibit clear interdependence over time. 相似文献

In the U.S., virtually no new coal-fired power plants have been built in recent years. Both industry experts and academics seem to believe that no rational firm will build a new coal-fired plant. Will such a trend continue in the future? To provide insights into this question, we investigate the optimal decision of an electricity company with an irreversible and deferrable opportunity to build either a new coal-fired or natural gas-fired power plant as its new base-load resource. According to our real option analysis, the optimal decision depends on the location. In the case of the eastern U.S., it is optimal to choose a natural gas plant if a firm is given a choice among a new natural gas plant, a new coal plant and deferring the investment. However, contrary to the common sentiment in the industry and academia, building a new coal plant in the western U.S. is still more economical than building a new natural gas plant in the absence of emission pricing. Furthermore, introducing carbon pricing to western U.S. states, as California did, can substantially increase the probability that a firm will optimally choose a natural gas plant over a coal plant. 相似文献

In the context of the Partnership Agreements between the European Union (EU) and the African, Caribbean, and Pacific countries, this study estimates ad valorem tariff equivalents of European food safety standards on imports of key horticultural and fish products from Kenya, Tanzania, Uganda, and Zambia. The study uses an extension of the price‐wedge method to account for imperfect substitution and factor endowment in monopolistic competition. The estimated tariff equivalents are 55% and 98% for imports of fresh peas from Zambia to the Netherlands and the U.K., respectively. They range from 39% to 64% for imports of green beans and avocados from Kenya and from 63% to 270% for imports of frozen fish fillets in EU countries from the East African Community. We also observe large variations in tariff equivalents for the horticultural and fish products over time and EU importing countries. 相似文献

This paper introduces a model seeking to explain the discretionary write-downs, write-offs, and other restructuring provisions reported by managers. The model comprises a firm, a manager, and a financial market. The firm is about to be restructured. The manager has some private information about the likelihood of success of his restructuring action. The manager may recognise all or part of the expenditure associated with his future restructuring action by reporting a discretionary restructuring provision. The manager chooses whether or not to report a provision, recognising the impact of the provision on his compensation. The paper shows how, under certain conditions, the manager may credibly communicate his private information to investors through his provision policy. Testable implications are consistent with the empirical evidence reported by Strong and Meyer (1987), Elliott and Shaw (1988), and Zucca and Campbell (1992). 相似文献
