Marginal areas of the world, including tropical highlands, tropical coastal zones, and arid lands, are problematical for development. They are ecologically special areas, often of vital consequence to the stability of more populated regions nearby. Commonly, their peoples are culturally distinct. To develop marginal areas it is suggested that “transformational” development may be appropriate. Transformational development recognizes the importance of equity and of working with existing resource systems already ecologically and culturally appropriate to the area. In marginal areas, a special application of transformational development could include incremental changes in existing systems and their connection to modern international systems so as to benefit the inhabitants of marginal areas and to supply commodities and goods demanded in the rest of the world. By rethinking ideas about resources, an exploratory framework for such transformation is examined. This framework uses the concept of “resource system”, a concept which might play an important part in the application of equitable future global development efforts. 相似文献

Distinguishing characteristics of General Purpose Technologies (GPTs) are identified and definitions discussed. Our definition includes multipurpose and single-purpose technologies, defining them according to their micro-technological characteristics, not their macro-economic effects. Identifying technologies as GPTs requires recognizing their evolutionary nature, and accepting possible uncertainties concerning marginal cases. Many of the existing ‘tests’ of whether particular technologies are GPTs are based on misunderstandings either of what GPT theory predicts or what such tests can establish. The development of formal GPT theories is outlined, showing that only the early theories predicted the inevitability of GPT-induced showdown and surges. More recent GPT theories, designed to model the characteristics of GPTs, do not imply the necessity of specific macro effects. We show that GPTs can rejuvenate the growth process without causing slowdowns or surges. We conclude that existing criticisms of GPT theory can be resolved and that the concept remains useful for economic theory. 相似文献

This paper developes a bioeconomic model to analyse the economic losses from the reduced harvesting of prey species resulting from an increase in the stock of a natural predator. Examples of large mammals creating economic damage are whales and African elephants. The economic losses depend critically on the actual management of the prey stock, although the three measures we develop are equal when the stock is managed so as to maximize the sustained economic rent from the prey species. Predation losses are illustrated by the case of the Northeastern Atlantic Minke whale, where the estimate of the average predation cost per whale in 1991–1992 is between $US 1780 and $US 2370, using Norwegian cost and earnings data. A ten percent stock increase is estimated to cause a loss of almost $US 19 million to the fishers of the prey species. If half of this cost were assigned to Norway it would be equivalent to 2.8 and 6.7 percent of the gross profits of the Norwegian cod and herring fisheries, respectively. 相似文献

The stochastic approach to index numbers has been successfully applied to the estimation of inflation, the world interest rate and international competitiveness.?One distinct advantage of this approach is that it provides the whole distribution of the index, not simply one value. In this article, we extend the stochastic approach to the estimation of a stock market index. We demonstrate how this approach can be used to identify ‘redundant stocks’ that do not contribute significantly to the overall index.?For index tracking purposes, these stocks can be safely excluded. 相似文献

People are attracted to the idea of nationalism and a national identity. Existing literature proposes that social heterogeneity has a detrimental effect on national identity. We contribute to this literature by proposing that religious diversity, as another form of social heterogeneity, can better explain the formation of a national identity. We construct an index for national identity using information from the World Values Survey on peoples' affection for their nation. We then analyze the relationship between national identity and religious diversity. The results suggest that religious diversity is significantly and negatively related to national identity. We also find support for the previous finding that ethnic diversity does not seem to be related to national identity. Democratic institutions and mobility throughout the country are positively related to national identity if religious diversity is sufficiently high. Democratic institutions can overcome the negative effect of religious diversity on national identity. 相似文献

This study examines the impact of multiple quasi-fixed assets on the imputed returns to farmland. The results indicate that the presence of additional quasi-fixed assets causes the true shadow value of farmland to deviate from its imputed value. The results also indicate that when the potential existence of multiple quasi-fixed assets is explicitly modelled, the shadow value of farmland approaches reported cash rental values. 相似文献
