This paper draws on a sample of innovative Catalan firms to identify how two main sources of innovation – internal R&D and external R&D acquisition – affect productivity in the manufacturing and service industries. The sample comprises 1612 innovative firms from the fourth European Community Innovation Survey (CIS-4) during the period 2002–2004. We compare empirical results when applying the usual OLS and quantile regression techniques controlling with a non-parametric sample selection. Our results indicate the different patterns that are attributable to the two sources of innovation as we move up from lower to higher conditional quantiles. First, the marginal effect of internal R&D on productivity decreased as we moved up to higher productivity levels. Second, the marginal effect of external R&D acquisition increased as we moved up to higher productivity levels. Finally, empirical results show significant complementarities between internal and external R&D, which are higher for knowledge-intensive service sectors.  相似文献

An evolutionary model of the size distribution of firms   总被引:2,自引:0,他引:2  
An analytical study of the evolution of the distribution of firm size in an industry is presented. A drift-diffusion model is proposed to express the time-evolution of density of firm size within the industry. The model blends the conventional, more or less static, determinants with the kinds of dynamic considerations introduced by stochastic processes of evolutionary dynamics. The steady-state distribution as well as the dynamic behavior of the model are derived. Parameters in the resulting analytical expressions are then fit to a population of firms in the non-manufacturing service sector. The empirical portion of the paper validates the proposed evolutionary model.  相似文献

The industry life-cycle of the size distribution of firms   总被引:2,自引:0,他引:2  
This paper analyzes the evolution of the distributions of output and employment across firms in U.S. manufacturing industries from 1963 until 1997. The firm size distribution changes significantly as an industry goes through stages of its life-cycle. The evolutions of the employment and output distributions also differ significantly, but display strong inter-industry regularities, including that the nature of the evolution depends on whether the industry is experiencing growth, shakeout, maturity, or decline. The observed patterns have implications for theories of industry dynamics and evolution.  相似文献

This paper analyzes the different compositions of the Catalan governing coalitions during the current democratic period, and offers some predictions about the coalitions that can be expected in the future. During this period, in Catalan politics, there have been two main political issues over which the different parties have taken positions: rightist versus leftist with respect to economic policy, and sovereign versus centralist with respect to the power distribution within the state. I find that for any allocation of parliament seats there is a key party: a party that has a clear advantage in terms of being able to decide the composition of the governing coalition. I show the features that allow a party to become the key party and those that affect the size of the advantage of the key party.

We investigate whether financing constraints affect the size distribution of Chinese industrial firms from 1998 to 2007. Although the firm size distribution does not follow Zipf distribution in China, it is approaching Zipf distribution over time. In general, financing constraints have a robustly negative effect on the size distribution of firms. Furthermore, firms in Western China grow significantly more equally after controlling for financing constraints. However, the effect of financing constraints in Central China is significantly negative, and the effect of financing constraints on firm size distribution in Eastern China is insignificant. We thus expect a non-linear relationship between financing constraints and firm size distribution.  相似文献

市场结构、流通能力与我国农产品流通企业扩张绩效   总被引:1,自引:0,他引:1  
通过对企业扩张影响因素全面的理论梳理,构建一个新的企业扩张行为分析模型,可以认为企业扩张行为并非是外部因素决定的,企业扩张行为绩效的决定是内部性的.在这一企业扩张新假设条件下,企业在竞争中的能力的积累是流通企业扩张行为取得绩效的根本来源.运用这个模型对中国农产品企业扩张问题进行实证研究,从而对我国农产品流通企业扩张的合理化提出相关建议.  相似文献

This paper deals with the occurrence and spatial distribution of collaborations within biotechnology. By starting from a total population of 45 firms involved in biotech R&D, we shed light on how many collaborate with (1) other firms, (2) venture capitalists, and (3) actors in science and technology and whether these partners can be found in the region, nation or in the rest of the world. Possible explanations for the different patterns are drawn out.  相似文献

We argue that ethical principles in advertising and market communication cannot be properly discovered and applied to gambling without a deep understanding of its probabilistic implications, in particular when extreme events are influential. We carry out a probabilistic analysis of lottery games with lifetime prizes in order to derive sound recommendations about the pertinent information that should be communicated to nudge gamblers. We propose to focus on the cumulative distribution of net gains, for which there is currently no information available to gamblers. This holds true for structured products in which extreme events matter as well.  相似文献

The purpose of this paper is to show that there exist models other than the stochastic ones that make predictions of the shape of the size distribution of establishments and firms, and that there is an important non-stochastic component in the forces determining the distributions. The paper presents a model in terms of a dynamic production and cost theory, involving the notions of optimal capacity expansion and economies of scale. It is shown that the distribution of plant sizes generated by the model tend to be of a typically skew type and also has certain similarities with the log normal and Pareto distributions.  相似文献

There exists a remarkable concern among financial analysts and policy makers about the high level of cost dispersion in banking. A model of distribution dynamics is applied to the Spanish banking companies in order to analyse whether such a dispersion is so high and if some factors like, for instance, specialization factors might somewhat influence the dynamics of both financial and operating expenses. Results show that there does not appear to exist a decrease in the level of cost dispersion, although firms' relative positions are changing. Yet, when controlling for the varying output mixes, firms produce results which differ much, as dispersion - assessed by means of density functions estimated nonparametrically - decreases substantially, suggesting concurrence is higher among firms with similar output mixes.  相似文献

This paper analyses how US, Japanese, and European HDD firms responded to technological shifts in the hard disk industry from 1973 through 1996. Leading incumbent US HDD firms were frequently forced out of the market. Leading Japanese incumbent firms in the same industry, however, were not displaced by these changes. US startup firms thrived under these technological shifts, displacing US incumbent firms. Japanese startups did poorly. European firms encountered the worst of both worlds: its incumbent firms were frequently displaced by technological changes, as were US firms; while startup firms (with one exception) performed as poorly as those in Japan.  相似文献

Innovation strategy and the patenting behavior of firms   总被引:2,自引:0,他引:2  
This paper investigates whether firms’ innovation strategies affect their patenting behavior, as measured by both the probability of having a patent portfolio and the number of active patents held. Three main dimensions of an innovation strategy are taken into account: the relative importance of basic research, applied research and development work in total R&D activities, the product or process orientation of innovation efforts, and the extent to which firms enter into collaborative R&D with other institutions. The major findings can be summarized as follows: (1) taking into account the various dimensions of an innovation strategy turns out to approximate the patenting behavior of firms better than the traditional Schumpeterian hypotheses related to firm size and market power; (2) there is a positive relationship between the patent portfolio of firms and an outward-oriented innovation strategy characterized by R&D partnerships with external organizations - scientific institutions and competitors in particular; (3) process-oriented innovators patent less than product-oriented innovators; (4) a stronger focus on basic and applied research is associated with a more active patenting behavior; (5) firms that perceive high barriers to innovation (internal, risk-related or external barriers) have smaller patent portfolios; (6) the perceived limitations of the patent system do not significantly influence the patenting behavior, suggesting that firms patent for other strategic reasons than merely protecting innovation rents.  相似文献

Conclusions We have assumed a specific statistical process which governs the competition among firms on the market.This process assumes that the consumer choice in the market is the decisive factor in determining size distributions. There are clearly many other relations e. g. between firms that are important for the process. We have assumed that they are of minor importance.We have assumed that the size distribution has reached an equilibrium and it is this equilibrium that we have studied. This is at best only true approximately. An extension of the presentation above would be to study non-equilibrium situations (open systems) which has proved to be fruitful in other contexts.  相似文献

This paper analyses the impact of environmental liability regimes on the capital structure of firms. We show that imposing environmental liability only on polluting firms, with limited liability, increases use of bank debt. Extending environmental liability to banks lowers bank borrowing relative to liability only on firms, with an ambiguous effect relative to no liability. Using US industry-level data we estimate a reduced-form model of bank borrowing by firms and show that the introduction of environmental liability only on firms increased bank borrowing by 15–20%, but when liability was extended to banks, borrowing returned to a level slightly higher than with no liability.  相似文献

In this paper, we confront the theoretical motivations of the consumption of eco-friendly products and the factors influencing the European perceptions regarding the fact that “fish caught using an environmentally friendly technique may carry a special label”. We take advantage of the recent integration of non-economic elements in the microeconomic analysis of consumers' behavior in order to highlight the factors leading to their demand for green products. Thanks to an original European survey on seafood product carried out on more than 5000 consumers, we test the influence of intrinsic motivation, information, localization and socio-economic factors on the demand for an eco-label for fish.Our results show a significant connection between the desire for eco-labeling and seafood features, especially the freshness of the fish, the geographical origin of the fish and the wild vs farmed origin of the fish. Moreover, we prove the major role played by the fish price. We also demonstrate that the ecological issue regarding fisheries is highly connected to consumer information, intrinsic motivation and socio-economic status: the typical “green fish consumer” is a young woman, well educated, well informed on the state of marine resources and not very trusting of the regulation of the fisheries. Consumers who are aware of the importance of marine resource preservation have the same profile.  相似文献
