R&D competition, absorptive capacity, and market shares   总被引:3,自引:0,他引:3  
This paper deals with an oligopolistic industry where firms are engaged in cost-reducting R&D activity to maximize their market shares. The existence and uniqueness of a feedback-Nash-optimal R&D strategy for each firm are discussed. Our simulations highlight that variations in spillovers hardly influence the firms' R&D investment, if their absorptive capacities to exploit extramural knowledge depend on their R&D efforts. Moreover, extramural knowledge cannot completely replace in-house R&D. However, a high level of public R&D favors the firm with the most restrictive R&D expenditure constraint and/or with the lowest initial R&D stock, provided it invests in R&D.  相似文献

This paper aims to identify genuine technological spillovers from multinational firms (MNEs). To this end, we use data on R&D from MNEs to measure spillovers, while most of the existing literature uses output to measure the foreign presence in an industry (what we call output-based spillovers). In line with the existing literature, we distinguish between horizontal spillovers (i.e., intra-industry linkages) and vertical spillovers (i.e., backward—or downstream—and forward—or upstream—inter-industry linkages). Our results show that the three types of technological spillovers from MNEs are positive, with the horizontal spillovers the larger ones, followed by backward spillovers. The effect of forward spillovers is much smaller in magnitude. Moreover, we find that not controlling for industry size (i.e., technological spillovers from all firms in an industry) leads to underestimating both horizontal and backward spillovers from MNEs, and to overestimating forward spillovers from MNEs. Finally, we find that the distinction between technological and output-based spillovers is of great relevance. The size of backward technological spillovers is approximately 44% of the size of output-based backward spillovers, while for horizontal spillovers both types of spillovers are quite similar. Importantly, output-based forward spillovers are negative while technological forward spillovers are positive.  相似文献

Social economy enterprises (SEEs) are arousing notable interest as promising alternatives where social innovation, business ownership and governance are concerned. In this context, a renewed debate about the internal changes and organizational trajectories experienced by these organizations has emerged in the scholarly literature. This special issue aims to contribute to ongoing debates in this field by advancing our understanding of the external pressures and internal dynamics that can trigger degeneration in SEEs, the conditions and factors that allow SEEs preserving their hallmark values and practices, and the resources and processes of organizational change that SEEs can deploy to overcome degeneration and regenerate. In this editorial introduction we introduce the topic of research, describe the content of the current special issue, and highlight some conclusions and possible directions for future research.  相似文献

This article analyzes the contribution of certifiable environmental management standards—such as ISO 14001 and the Eco‐Management and Audit Scheme (EMAS)—to corporate environmental performance. Based on a content analysis of 414 third‐party‐verified environmental statements from EMAS‐registered Spanish organizations, which included information for around 6,700 detailed indicators, a weak improvement in environmental performance was found. Less than half of the analyzed indicators—namely, 48.27%—revealed a net improvement. Similarly, analysis of the justifications of the registered companies for the lack of improvement points to a rather symbolical adoption of the certification, intended to do only the bare minimum. These findings call into question the prevailing opinion about the positive impact of voluntary certifiable environmental management standards on environmental greening. Implications for managers and public policy makers, as well as for other stakeholders, are discussed.  相似文献

The main purpose of this paper is to present an empirical analysis of the sequence relating the performance of the firm to its behavior, which in turn depends upon the origin and personal characteristics of the entrepreneurs. The data are drawn from new Spanish firms. A typology of new entrepreneurs is constructed, based on their basic work aspirations. Each type of entrepreneur is then examined, in terms of the origin and personal characteristics of the members of the class. The results of the study show that significant differences exist among the entrepreneurs and firms of each type, especially in terms of the size of the firm (number of employees) and its evolution over time. The implications of these results, for the theory of entrepreneurship and for the design of policies towards the creation of new firms, are then derived.  相似文献

The purpose of this paper is to test for evidence of opportunistic “political business cycles” in a large sample of 18 OECD economies. Our results can be summarized as follows: 1) We find very little evidence of pre-electoral effects on economic outcomes, in particular, on GDP growth and unemployment; 2) We see some evidence of “political monetary cycles,” that is, expansionary monetary policy in election years; 3) We also observe indications of “political budget cycles,” or “loose” fiscal policy prior to elections; 4) Inflation exhibits a post-electoral jump, which could be explained by either the pre-electoral “loose” monetary and fiscal policies and/or by an opportunistic timing of increases in publicly controlled prices, or indirect taxes.  相似文献

In situations where quality is fixed, the widely used RPI‐X regulatory mechanism has a number of desirable properties, such as convergence to a second best optimum. Theoretical analysis of this mechanism in the case of endogenous quality is limited and therefore regulators have typically imposed constraints on the firm's quality choice in ad hoc manners, either by mandating quality levels, or by including quality adjustment factors in the RPI‐X mechanism. In this paper, we construct the rigorous theoretical counterpart of these manners of including quality measures in the constraints faced by a regulated firm. This mechanism converges to second best optimum. It works by offering the firm trade‐offs between prices and qualities based on the choice it made in the previous period; however, reflecting the practical problem valuing quality, the informational requirement to select these trade‐offs appropriately is qualitatively stronger than in the fixed quality case. Moreover, even when the informational problem can be overcome, we identify a further potential pitfall in the approach taken in practice by regulators, and show that, in order to avoid it, the regulated firm should be subject to an additional constraint, which we label the distance constraint, and which can be interpreted as requiring the firms to choose prices and qualities within a band in every period.  相似文献

Zusammenfassung Vorteile der Entwicklungsl?nder aus einer m?glichen Handelsliberalisierung für Rindfleisch und Zucker in den Industriel?ndern. - Die Studie geht von der Annahme aus, da\ die Gruppe der Industriel?nder ihre gegenw?rtigen Handelshemmnisse für Zucker und Rindfleisch aufhebt, und versucht zu ermitteln, welche potentiellen ?nderungen an Wohlfahrt und Devisenerl?sen sich daraus für die Entwicklungsl?nder ergeben. Grundlage ist ein komparativ-statisches Gleichgewichtsmodell für den Weltmarkt eines Gutes. Die Ergebnisse deuten darauf hin, da\ die Entwicklungsl?nder für beide Produkte zusammengenommen eine Steigerung ihrer Devisenerl?se um 6,6 bis über 12 Milliarden US-Dollar pro Jahr (auf der Basis von 1980) erwarten k?nnen. Das ist nicht nur absolut oder relativ sehr viel, sondern auch im Vergleich zu der laufenden Entwicklungshilfe.
Résumé Bénéfices potentiels des PVD à cause d’une libéralisation de commerce en viande de boeuf et sucre par les pays industrialisés. - Cette étude essaie d’identifier le changement potentiel de bien-être et des revenus en devises des PVD en supposant que le groupe des pays industrialisés éliminent leurs obstacles commerciaux actuels pour la viande de boeuf et le sucre. Le cadre essentiel est un modèle du type comparatif statique d’équilibre de marché mondial d’un seul bien. Les résultats suggèrent que pour les deux biens ensemble les PVD pourraient attendre une augmentation des revenus en devises entre 6,6 et plus que 12 milliards US $ par année (base 1980): un montant très grand non pas seulement en terme absolu ou relatif mais aussi en comparaison avec l’aide de développement pour les PVD.

Resumen Los beneficios potenciales de la liberalización de las importaciones de carne y azúcar en los países industrializados para los países en desarrollo. - Este trabajo intenta estimar el cambio en el bienestar y en el ingreso de divisas de los países en desarrollo, asumiendo que el grupo de países industrializados elimina las barreras al comercio actualmente vigentes para el azúcar y la carne. El marco teórico lo constituye un modelo de equilibrio de mercado para una materia prima de tipo comparativo-estático. Los resultados sugieren que para ambas materias primas los países en desarrollo podrían registrar un aumento en le ingreso de divisas entre 6,6 y 12 mil millones de dólares por a?o (a precios de 1980). Estas cifras no sólo son muy altas en términos absolutes o relativos, sino también si se las compara con los flujos de la ayuda al desarrollo.
