R&D activities are increasingly costly and risky and, as a consequence, measuring their performance and contribution to value becomes critical. This paper illustrates a formal model for measuring R&D performance, based upon a balanced and synthetic evaluation of quantitative indicators from five different perspectives of performance: financial, customer, innovation and learning, internal business, alliances, and networks. The model is built in coherence with the suggestions coming from the theory of measurement in soft systems, which gives relevant guidelines for ensuring validity, objectivity and inter-subjectivity of the model. Then, an application in a real R&D setting is described, which helps to understand the model and to enlighten its main advantages and limits.  相似文献

The paper analyses the determinants and the evolution of income disparities across regions within Central and Eastern European Countries (CEECs) over 1991–2011. We add to the literature in different ways. First, we adapt the categories that Rodriguez‐Pose used for studying convergence among old EU members to CEECs regions. This allows us to assess the relevance of geo‐sectoral groups (urban areas, old industrialized areas and peripheral areas) for newcomer regions. Second, we introduce a new category, that of ‘successful Foreign Direct Investment (FDI)‐based restructuring’ in order to capture regions that, often through considerable FDI, manage to reconvert their old industrial base. We then analyze whether this group helps understand catching‐up/falling behind processes in CEECs. We test the relevance of these groups by means of both non‐parametric and spatial regression analyses. We find that they help explain the increase in within‐countries’ regional disparities especially after the turn of the century.  相似文献

Using a bilateral trade equation derived from a monopolistic competition model, we investigate market access reciprocity in food trade among the United States, Canada, the European Union and Japan. We explore country- and industry-specific market access asymmetry through a border effect approach. Our findings reveal marked asymmetries in reciprocal border effects, both across countries and industries. Trade policy measures, particularly non-tariff barriers (NTBs), the degree of product differentiation and a ‘home bias’ in preferences, are important factors in explaining levels in border effects. Asymmetries in border effects are mainly explained by trade policies. JEL no.  F13, F14, Q17  相似文献

This study aims to examine the relationships of managers' compassionate goals with innovation and performance in small- and medium-sized enterprises (SMEs). By integrating social exchange theory with social information processing theory, we hypothesize a serial mediation model in which organizational cooperation and firm innovation sequentially mediate a positive relationship between managers' compassionate goals and firm performance. However, we predict that this positive indirect effect would occur only when managers have low self-image goals and there is a high innovation-supportive work environment. Based on survey data from a sample of 116 SMEs in France, our results provide support for our predictions. This study contributes to the literature by disclosing the mechanisms and boundary conditions of the relationship of managers' compassionate goals with SMEs' innovation and performance. Theoretical and managerial implications of this study are discussed.  相似文献

Systemic liquidity risk, defined by the International Monetary Fund as “the risk of simultaneous liquidity difficulties at multiple financial institutions,” is a key topic in financial stability studies and macroprudential policy-making. In this context, the complex web of interconnections of the interbank market plays the crucial role of allowing funding liquidity shortages to propagate between financial institutions. Here, we introduce a simple yet effective model of the interbank market in which liquidity shortages propagate through an epidemic-like contagion mechanism on the network of interbank loans. The model is defined by using aggregate balance sheet information of European banks, and it exploits country and bank-specific risk features to account for the heterogeneity of financial institutions. Moreover, in order to obtain the European-wide topology of the interbank network, we define a block reconstruction method based on the exchange flows between the various countries. We show that the proposed contagion model is able to estimate systemic liquidity risk across different years and countries. Results suggest that our effective contagion approach can be successfully used as a viable alternative to more realistic but complicated models, which not only require more specific balance sheet variables with high time resolution but also need assumptions on how banks respond to liquidity shocks.

An important body of research has developed in recent years, explaining ways in which product materials influence user experiences. A priority now is to ensure that the research findings are adopted within an educational context to deliver contemporary curricula for students studying the subject of materials and design. This paper reports on an international initiative to develop ‘materials experience’ as a formal subject of study, complementary to traditional technical and engineering approaches to materials and design education. General learning objectives for materials experience are established, followed by specific attention to three kinds of experience that arise during user–material–product interaction: gratification of senses, conveyance of meanings, and elicitation of emotions. For each of these kinds of experience, a specially devised active learning exercise is explained in detail. In combination, these exercises are argued to deliver a good foundation for student appreciation and action on designing for material experiences in product design. The paper concludes with recommendations for how to responsibly redress the imbalance that exists in materials and design education, by transitioning from a culture of ‘imparting knowledge about materials’ to a culture of ‘generating experience with materials’.  相似文献

We study the revenue in auctions of a single object when the number of bidders becomes large. We show that all sequences of auctions belonging to a class of mechanisms have limiting expected revenue equal to the expected best-use value of the object. An important special case that is covered is common value auctions, but more generally not even affiliation of values is assumed. This provides an asymptotic revenue equivalence result for settings beyond that of private values. Journal of Economic Literature Classification Numbers: D44, C72.  相似文献

Open firms are not equally successful. This is because, in order to benefit from external sources of knowledge, firms must be able to absorb such knowledge. The paper outlines a firm's context as a set of organizational and social features, which may be considered absorptive capacity antecedents. It explores the mediating role of such antecedents in the relationship – hitherto insufficiently researched – between the degree of openness and innovative performance. The use of a methodology combining both direct interviews and survey of Italian firms has allowed us to confirm the supposed mediating role. We also identify different modes for companies to open up their innovation process and, for each of them, the antecedents that are consistent with choices regarding the degree of openness.  相似文献

This paper studies convergence in per-capita GDP across European regions over the period 1980–2000. We use median unbiased estimators of the rate of convergence to the steady-state growth path, while allowing for unrestricted patterns of heterogeneity and spatial correlation across regions. By permitting the model parameters to be completely different across regions, not only we avoid imposing strong a priori assumptions but we are also able to analyze the spatial patterns in the estimated coefficients. Our results differ from those found using conventional estimators. The main differences are: i) the mean rate of convergence is much lower; ii) for most regions this rate is zero; iii) the number of regions for which we reject equality in trend growth rates is substantially lower. We also find significant evidence of correlation of growth rates across neighbor regions and across regions belonging to the same country.  相似文献
