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

This article estimates the impact of longevity risk on pension systems by combining the prediction based on a Lee-Carter mortality model with the projected pension payments for different cohorts of retirees. We measure longevity risk by the difference between the upper bound of the total old-age pension expense and its mean estimate. This difference is as high as 4% of annual GDP over the period 2040–2050. The impact of longevity risk is sizeably reduced, but not fully eliminated, by the introduction of indexation of retirement age to expected life at retirement. Our evidence speaks in favor of a market for longevity risk and calls for a closer scrutiny of the potential redistributive effects of longevity risk. 相似文献

This study analyzes the effect of informational clues and Chef-Cuisine congruence, and their relation to advertisements for a Japanese restaurant. Two experiments were conducted with 171 consumers. Findings supported the following: Congruence between a Japanese restaurant and Japanese Chef results in higher approval ratings than the combination of Japanese restaurant with Brazilian Chef. However, if the advertisement states that the restaurant has won an award, then Chef-restaurant congruence is no longer an important factor in consumers’ evaluations. 相似文献

This article proposes and validates a financial protection perception scale (FPPS) from the perspective of the financial services consumer. The scale was applied to a sample of 1137 individuals residing in Brazil and validated using exploratory and confirmatory factor analysis and standard multivariate validation methods. The FPPS, composed of 14 items, allows the development of an indicator that defines the level of protection perceived by the consumer of financial services, evaluated along the dimensions of transparency, suitability, security, and complaints. The tests and fit indices indicated the reliability and validity of the FPPS. With this scale, researchers, managers, and policymakers can assess the extent to which consumers feel protected when using financial services. 相似文献
