Conclusion When a technology proprietor cannot exploit his advantage by means of ownership of a production facility abroad, a sales contract with “buy-back provisions” may, in fact, be a trade-enhancing resolution to a situation of information-asymmetry between buyer and seller. The important implication is that not all forms of countertrade can be summarily dismissed as inefficient. Just as foreign direct investment can be seen to be a response to environmental or market imperfections, “buy-back” may be a way to deal with institutional or regulatory obstacles such as the prohibition of foreign ownership.  相似文献

Among the second-best approaches for the regulation of pollution,little attention has been paid to the distorting effect of intensivemargin policies on the extensive margin. This article shows,within a dynamic framework, that regulation of the intensivemargin has to be complemented by regulation of the extensivemargin. Depending on the elasticity of the pollution functionwith respect to nitrogen use, the appropriate regulation atthe extensive margin is zero, a tax or a subsidy. We show empiricallythat combining a nitrogen tax with land-use taxes is about 18per cent more cost efficient than a nitrogen tax alone and 58per cent more efficient than off-site abatement in the formof groundwater treatment.  相似文献

The Common Heritage Principle:   总被引:1,自引:0,他引:1  
A bstract An effort is underway to apply the common heritage principle to certain unique global resources while promoting economic development Under this precept, property rights to such resources are said to belong to all nations and their citizens rather than being subject to national sovereignty The doctrine is examined in theory and as applied in the outer space and law of the sea treaties Its possible application to Antarctica is explored in relationship to the Antarctic Treaty System (ATS) which is now considering a minerals regime for the continent Assessing the international political situation suggests the powerful bloc of ATS nations will ignore the common heritage principle However, a different outcome is possible, given a convergence of the Antarctic mining and global atmospheric issues of the greenhouse and ozone varieties Under this scenario, the global atmosphere and Antarctica would be common property resources whose property rights are owned by all nations  相似文献

Bernard Cazes 《Futures》1973,5(3):272-280
Professor Cazes critically examines the futures studies conducted in France as part of the VIth Plan (1971–1975). He identifies three classes of research—vertical, horizontal and synthetic— and analyses the strengths and weaknesses of each as they relate to policy planning.  相似文献

This article provides empirical evidence and contributes to theory building concerning business model fit and dynamics in the area of solutions business. Business models are seen in this context as going beyond considerations such as offerings and internal processes or even relationships, and as including network and market considerations. Indeed the paper highlights the fact that a business model is not firm-focused, nor dyad-focused, but rather network-, and even market-focused, demonstrating that a business model is not static, but dynamic. Manufacturer and customer continuously shift form and content of their respective business models to adapt both to the needs of the counterpart and to market context. A qualitative case study approach is adopted, with subsequent content analysis. The case study relates to the aerospace industry with focus on a complex engineering firm, one of the largest aircraft manufacturers in the world, its customer — a national airline — and their network partners of various kinds. The data were collected through multiple face-to-face interviews with managers in both companies, as a part and parcel of a network of actors that influences and is influenced by the supplier–buyer relationship. Relationships over time between these firms and network partners are described, highlighting the interplay of products and services related to the provision of solutions. Findings highlight the dynamic nature of business models over the relationship lifecycle between supplier and customer in a complex engineering environment, and the need for reciprocal adjustment of models.  相似文献
