Based on an indicator measuring the technological level of aircraft, this paper shows that in the aircraft industry, firms are obliged to deal not only with high technological barriers, but growing financial and market barriers, too. In order to reduce these, a complex network of relationships has developed over time. This network involves both main firms belonging to the world oligopoly and firms capable of offering specialised technology and/or a potential broadening of the market. The result is a worldwide production organisation. This paper highlights the fact that the aircraft industry is undergoing a global reorganisation featuring an integration process where six groups (two in Europe and four in the United States) have come to the fore. In the future, it will be possible to imagine new forms of co-operation between the emerging European and American groups. 相似文献

This article presents evidence on the positive effect of international trade on productivity growth using industrial level data preceding and following Brazil's trade liberalization in 1988–90. Our data reveal large and widespread productivity improvement across industries after barriers to trade were drastically reduced. Econometric results confirm the association between trade liberalization and productivity growth and show that the impact was indeed substantial: The observed tariff reduction in the period brought a 6% estimated increase in total factor productivity growth rate and a similar impact on labor productivity. 相似文献

Markets with network effects are typically concentrated. The aim of this paper is to discuss some recent work on “incumbency advantage.” That is, the fact that firms already installed generate higher profits than entrants even if the latter offer identical or even better terms (in terms of price and quality) to consumers. In particular, we review recently known sources of the advantage and potential mitigating factors and point to a number of open issues. 相似文献

The internationalization of telecommunications services and products, together with Spain's entry into the European Economic Community, have created increased interest in the Spanish national telecommunications system. In this article are described the current situation for Spanish telecommunications, and the initial actions being taken to adapt its structure and legal framework to the new environment. Attempts are being made to provide it with enough flexibility to evolve in the most suitable direction for the country to participate in the movements happening on the world market. 相似文献

Operators of telecommunications networks, network systems manufacturers and policy markers have placed their hopes on ISDN for a stable and brilliant telecommunications future. However, non-voice service providers, customer premises equipment manufacturers and large users fear that the envisaged network approach will not serve their future requirements. Telecommunications networks will have a strategic importance in national economic development. It is important not to constrain that development by tying them to an inappropriate and inflexible network structure. In this article the uncertainties of the ISDN network are reviewed, questions are raised and the evolution of the network is examined, from the perspective of the actors involved in the sector: large users, equipment manufacturers, policy makers and service providers. 相似文献

The aim of this paper is to analyse the relationship between environmental and economic performance from the resource-based
theory within firms of the fresh fruit and vegetables sector. This study considers that the adoption of environment-friendly
practices has a greater influence on firms’ opportunities and abilities in the agricultural sector than in manufacturing sectors
and leads to closer links between performance variables. The reference for this empirical analysis is a panel data of horticultural
farming-marketing firms in Spain. The voluntary environmental programmes and the heterogeneity of their application lead us
to regard acquiring a competitive advantage as a relevant driver to improve environmental performance in this sector. A simultaneous
equations model is suggested reflecting the differential environmental effect and the assumption of endogeneity among variables.
The results show a positive impact of environmental differentiation on profitability and market share, also suggesting that
the perception of this positive experience implies greater environmental performance.

The object of the present article is to offer a decomposition of productivity indices incorporating environmental changes. The model followed is an input oriented approach related to undesirable output (environmental performance attribute) in horticultural marketing cooperatives. This study is motivated by both the lack of analysis of environmental performance's effects on agribusiness productivity and the relevance of cooperative firms in the European agricultural model for attaining sustainability. For this purpose, bootstrapped envelopment analysis is applied and the best practice frontier obtained corresponds to decision making units showing the best environmental behaviour. The Malmquist total factor productivity (TFP) is decomposed into technological change, efficiency and environmental change. In the second stage, the correlations of these changes with other management variables of cooperatives are analysed. The indicators obtained, on one hand, advice about the nonseparable distance function estimations when the environmental factor is introduced. On the other hand, the results display a relevant increase in efficiency and environmental components for the period under study showing a high influence from labour qualification, environmental effort and spillover effect in the sector. 相似文献

Logistic and power law methodologies for both retrospective and prospective analyses of extended time series describing evolutionary growth processes, in environments with finite resources, are confronted. While power laws may eventually apply only to the early stages of said growth process, the Allee logistic model seems applicable over the entire span of a long range process. On applying the Allee logistic model to both the world population and the world gross domestic product time series, from 1 to 2008 AD, a projection was obtained that along the next few decades the world should experience a new economic boom phase with the world GDP peaking around the year 2020 and proceeding from then on towards a saturation value of about 142 trillion international dollars, while the world population should reach 8.9 billion people by 2050. These results were then used to forecast the behavior of the supply and consumption of energy and food, two of the main commodities that drive the world system. Our findings suggest that unless the currently prevailing focus on economic growth is changed into that of sustainable prosperity, human society may run into a period of serious economical and social struggles with unpredictable political consequences. 相似文献

We present a model of capital accumulation and technology adoption in a vintage-capital framework. The model is an infinite-horizon/infinite-dimensional optimal control model: the firm employs a continuum of technologies (a continuum of heterogeneous capital goods). Capital goods are technology specific, their technology is related to vintage and technology progress. The entrepreneur maximizes the profits obtained by employing a continuum of technologies under the assumption of constant returns to scale and bearing adjustment costs for gross investments. The diffusion of a new technology is established by allowing the entrepreneur to invest in vintage capital goods. 相似文献
