Abstract. In this paper, we make a comparison of industry output, inputs and productivity growth and levels between seven advanced economies (Australia, Canada, France, Germany, the Netherlands, United Kingdom and United States). Our industry-level growth accounts make use of input data on labour quantity (hours) and composition (schooling levels), and distinguish between six different types of capital assets (including three information and communication technology (ICT) assets). The comparisons of levels rely on industry-specific purchasing power parities (PPPs) for output and inputs, within a consistent input–output framework for the year 1997. Our results show that differences in productivity growth and levels can be mainly traced to market services, not to goods-producing industries. Part of the strong productivity growth in market services in Anglo-Saxon countries, such as in Australia and Canada, may be related to relatively low productivity levels compared with the United States. In contrast, services productivity levels in continental European countries were on par with the United States in 1997, but growth in Europe was much weaker since then. In terms of factor input use, the United States is very different from all other countries, mostly because of the more intensive use of ICT capital in the United States.  相似文献

Knowledge Spillovers in Europe: A Patent Citations Analysis   总被引:15,自引:0,他引:15  
This paper addresses the pattern of knowledge flows as indicated by patent citations between European regions. Our findings support the hypothesis that there are important barriers to knowledge flows in Europe. Patent citations occur more often between regions which belong to the same country and which are in geographical proximity. Furthermore, patent citations are industry specific and occur most often between regions that are specialised in industrial sectors with specific technological linkages between them. Patent citations are also more frequent when the citing region belongs to the same linguistic group as the cited region.

We formulate a simple multiagent evolutionary scheme as a model of collective learning, i.e. a situation in which firms experiment, interact, and learn from each other. This scheme is then applied to a stylized endogenous growth economy in which firms have to determine how much to invest in R&D, where innovations are the stochastic product of their R&D activity, spillovers occur, but technological advantages are only relative and temporary and innovations actually diffuse, both at the intra and interfirm levels. The model demonstrates both the existence of a unique long-run growth attractor (in the linear case) and distinct growth phases on the road to that attractor. We also compare the long-run growth patterns for a linear and a logistic innovation function, and produce some evidence for a bifurcation in the latter case.  相似文献

This paper presents an industry‐level model of growth and trade, in which evolving specialization patterns are the endogenous result of innovation, international technology spillovers, learning‐by‐doing and balance of payments‐restricted growth. Differences between industries with regard to their share in consumption are shown to reinforce or mitigate the effects of specialization on aggregate productivity convergence patterns, depending on other parameters. The implications of the model are studied by means of simulation analyses for a wide range of parameter configurations.  相似文献

In the literature on innovation, interorganizational collaboration has been advanced as beneficial for the innovative performance of firms. At the same time, large‐scale empirical evidence for such a relationship is scarce. This article examines whether evidence can be found for the idea that interorganizational collaboration supports the effectiveness of innovation strategies. This article empirically addresses this research question by analyzing data on Belgian manufacturing firms (n=221) collected in the Community Innovation Survey, a biannual survey organized by Eurostat and the European Commission aimed at obtaining insights into the innovation practices and performance of companies within the various European Union (EU) member states. Tobit analyses reveal a positive relationship between interorganizational collaboration and innovative performance. At the same time, the impact on innovative performance differs depending on the nature of the partner(s) involved. These findings strongly suggest the relevance of adopting a portfolio approach to interorganizational collaboration within the context of innovation strategies.  相似文献

This article presents findings from an exploratory study into the content and impact of product innovation charters (PICs) in 86 North American corporations. The findings demonstrate that managers have some distinct preferences in terms of the items that they choose to include in a PIC and that certain components seem to be more important to mention than others. The findings also make evident the relationship that PICs have with selected performance measures. The results suggest that product innovation charters, like their mission statement 'cousins', may be of more value than most managers realize.  相似文献

Valuation of the prepayment option in Dutch mortgages is complicated. In the Netherlands, mortgagors are not allowed to prepay the full mortgage loan without a compensating penalty. Only a limited amount of the initial mortgage loan can be prepaid penalty‐free. We introduce a general model formulation for the valuation of limited callable mortgages, based on binomial trees. This model can be used for determining both the optimal prepayment strategy and the value of embedded prepayment options. For some mortgage types the prepayment option can be valued exactly, whereas other types require approximative methods for efficient valuation. The heuristic we propose here determines the prepayment option value efficiently and accurately for general mortgage types.  相似文献

Nurturing and growing innovative start-ups have become an important point on the political agenda. After the dotcom bubble, however, many financial schemes and incubation initiatives initiated, in the mid-nineties, were cancelled or down scaled. There was a consensus that innovative start-ups need more than just money. Networking and coaching were identified as additional needs. Besides this, there is a change in the intensity and nature of these needs during the different stages of the early life cycle. In this paper we make an in-depth study of three approaches to nurture and grow innovative start-ups. Each of these initiatives embeds in a very different national innovation system: Chalmers Innovation in Sweden and Anvar/Banque de Développement des PMEs in France, and Sitra's PreSeed Service in Finland. Each approach is compared in terms of its financing, networking, and coaching support, along the different stages of the start-up's life cycle.  相似文献

The international diversity of firms' fiscal year-end is relatively unknown. However, this diversity has practical implications for both accounting research and business comparability. In this study, we examine the backgrounds of the diversity. We found that differences in tiny, supposedly unimportant details in national legislation on fiscal year-end have a much stronger impact on fiscal year-end choice than the generally assumed cause of seasonality. In the last decade of international harmonization, we found only a few instances of fiscal year-end changes motivated by enhancing comparability. Worldwide, a weak drift towards December was found.  相似文献

The complexity of issues firms have to attend to make it impossible for CEOs to give their full attention to all issues concurrently. Drawing on the “attention‐based view” of the firm, this paper opens the black box of attention allocation in for‐profit social enterprises by showing how attention structures and the context in which the firm operates interplay. Utilizing empirical data on 148 for‐profit social enterprises, findings show that the attention structures—other‐regarding values, utilitarian identity, and resource availability—have a significant impact on the relative attention to social goals, while past firm performance as a context variable moderates these relations. Applying the principles of structural and situated attention, this paper makes an important contribution to management theory and attention allocation in for‐profit social enterprises.
