This paper challenges the common view that mature industries are always ripe for global strategies. Based on data from the European Domestic Appliance industry, this paper shows how changing economic conditions can diminish the value of global strategies. Critical in these shifts were simultaneous rises in demand for variety (that eroded the benefits of scale and continental market share) and decreases in manufacturing scale (that permitted new supply options), which reduced the extent of the strategic market to national dimensions. They added complexity that decreased the profitability of the global players and increased that of national strategies. The fluctuating fortunes of leading firms are shown to have been caused primarily by choices of strategy, not by national factor costs.  相似文献

Between 1974 and 1988, executives of DuPont, the world's largest producer of CFCs, were confronted with emerging evidence that CFCs were destroying the stratospheric ozone layer. The difficulty that executives face in such cases is that scientific knowledge develops over time and does not necessarily proceed in a straight line toward true conclusions. At the beginning of a new field of research, there is much uncertainty and disagreement among the experts. The solution of the ozone problem required a remarkable cooperation among science, business, and international governments. After looking at the role of DuPont executives in this drama, and the difficulties facing any executive dealing with uncertain science, the paper turns to an evaluation of the field of Business Ethics to see what light it might throw on this and analogous problems. Finally, the paper offers specific suggestions in terms of principles in dealing with uncertain science, and concludes that the course of action that DuPont followed, including some mistakes, can serve as a model for analogous crises.  相似文献

International mutual funds allow individual investors to diversify abroad at a reasonable cost. This paper tests whether international funds that actively engage in country and security selection outperform passive global benchmarks. We apply a mean-variance efficiency test that incorporates the practical prohibition against short sales of open-end mutual funds. Our tests reject the efficiency of the world equity market portfolio over the sample period, and our funds as a group outperform the inefficient world index. However, we find no evidence of security selectivity ability using a 12-country benchmark. We do find that active international funds provide global diversification benefits. Tests using the Positive Period Weight (PPW) measure of Grinblatt and Titman (1989), which is robust to nonlinearity in fund and benchmark returns, yield similar results.  相似文献

Trade intensity,country size and corruption   总被引:1,自引:0,他引:1  
Abstract. Several authors claim to provide evidence that governmental corruption is less severe in countries where trade intensity is higher or populations are smaller. We argue that theory is highly ambiguous on these questions, and demonstrate that empirical links between corruption and trade intensity – or country size, strongly related to trade intensity – are sensitive to sample selection bias. Most available corruption indicators provide ratings only for those countries in which multinational investors have the greatest interest: these tend to include almost all large nations, but among small nations only those that are well-governed. We find that the relationship between corruption and trade intensity disappears, using newer corruption indicators with substantially increased country coverage. Similarly, the relationship between corruption and country size weakens or disappears using samples less subject to selection bias.

This paper is based on the early stages of an international collaborative project investigating the structural changes of the confectionery sectors in Finland and the U.K. over the past two decades. An institutional perspective is used to extend conventional understandings of industries via the development of the sector concept. The network and community constructs are shown to be important devices for understanding the institutional character of a sector. Accordingly, the paper reveals the similarities and differences between the two national examples. An explanation is offered of the way domestic networks persist in both countries while contrasting community profiles are apparent.  相似文献

The paper examines a model of strategic infrastructure investment. Two oligopolistic firms compete on home and foreign product markets for market shares. The national governments support the firms in the market rivalry by providing cost reducing public infrastructure services that are financed out of taxing an input used in the production process. It is shown, that infrastructure policy can be used as an instrument for strategic trade policy. However, governments are facing the problem of balancing the burden of taxation and the benefits of infrastructures. The theoretical model also raises some critical issues with respect to the policy relevance of recent empirical infrastructure research.  相似文献
