We live in a world of nations, but also one of multi‐nation systems. These systems, or transnational regions, affect global economics, politics and diplomacy. Latin America is a widely recognised and documented transnational region. It contains subregional nation systems that might have all of the characteristics and significance of regions and might also affect the broader integration of Latin America. The author defines regionality on the basis of economic integration and measures it with two methods for Latin America, North America, three Latin American subregional systems and one arbitrarily defined nation system within Latin America. He finds a high degree of integration in Latin America, the Andean nations and the Southern Cone of South America. He finds only a modest degree of integration in North America and not significantly greater integration in South America than in Latin America. The division of Latin America into subregions is consistent with the incidence of sub‐regional trade initiatives in the past two decades and might be at least partly responsible for the limited progress to date towards Latin America‐wide integration. Latin American subregions might now be providing a foundation on which to build regionalism in the future.  相似文献

In this paper, threats to the world's wilderness areas are reviewed. The author argues for a global approach to this encroachment, so that countries struggling against adverse social and economic conditions are not forced to pay the price of mistakes made due to genuine ignorance or the greed of the more advanced nations. A classification of wilderness areas is given, and the threats facing them are outlined. The author then moves on to explain how ekistics, the science of human settlments, can be applied to the problem. In this way, he suggests, man's need to develop and the environment's need for protection can be united. The paper concludes with a plea for a multi-disciplinary approach and, more important, a general awareness that all environmental issues are related.  相似文献

Previous research in the price-quality area has largely limited its focus to the normal price range and has concentrated on physical goods almost entirely. This study examines the effect of offering a service for free and at an exaggerated price on the perception of its quality. Consistent with the theory developed in this paper, the experimental results suggest that when the tested services are offered for free and for exaggerated prices, they are perceived as lower in quality than when they are offered in a normal price range.  相似文献

This article examines the use of business incubators to enhance industrial innovation and new venture formation. Currently, the number of business incubators is rapidly growing. Yet, we have little solid evidence that such centers actually stimulate the growth and success of either innovations or new ventures. Gerald Udell examines incubators' resources and services in an effort to assess their potential impact. He conducted a survey of two hundred incubators and linked the results to a partial review of the literature to aid in the assessment of business incubators.  相似文献

A pricing model for default-free bonds under differentia! taxation of coupon income and capital gains is presented which explicitly considers coupon-induced tax clienteles. Subsequent analysis provides indirect evidence in support of the existence of the coupon-induced tax clientele effect, while direct evidence is provided by analyzing differences in marginal tax rates estimated across different coupon levels for sets of US Treasury bonds with the same maturity date. The results are also generally consistent with the traditional notion that marginal tax rates are inversely related to coupon levels.  相似文献

Land‐use change in developing countries is of great interest to policy‐makers and researchers with diverse interests. Concerns about consequences of deforestation for global climate change and biodiversity have received the most publicity, but loss of wetlands, declining land productivity and watershed management are also problems facing developing countries. Analyses of these problems are especially constrained by lack of data. This article reviews modelling approaches for data‐constrained environments that involve discrete choice methods including neural nets and dynamic programming, and research results that link individual household survey data with satellite images using geographic positioning systems.  相似文献
