This paper looks at the causes and competitive consequences enterprise diversification with reference to the experience of twelve large UK firms. It is noted although the majority of these firms diversified intially for defensive reasons, continuing diversification was often undertaken to enable the firm to maintain a satisfactory rate of earnings growth. In accordance with this goal, most of the twelve firms had acquired market leaders in diverse areas. A second conclusion therefore, is that diversification can add to the total market power available to the firm. The use of this power however, appears to depend upon the management philosophy and nature of resource allocation found within the firm.  相似文献

Every house is different. It is important that house price indexes take account of these quality differences. Hedonic methods which express house prices as a function of a vector of characteristics (such as number of bedrooms and bathrooms, land area and location) are particularly useful for this purpose. I consider here some developments in the hedonic methodology, as it is applied in a housing context, that have occurred in the last three decades. A number of hedonic house price indexes are now available. However, it is often difficult to see how these indexes relate to each other. For this reason I attempt to impose some structure on the literature by developing a taxonomy of hedonic indexes, and then show how existing indexes fit into this taxonomy. Also discussed are some promising areas for future research in the hedonic field. In particular, greater use needs to be made of spatial econometric and nonparametric methods to exploit the increased availability of geospatial data. The main criticisms of the hedonic approach are evaluated and compared with those of the repeat‐sales and stratified median methods. The overall conclusion is that the advantages of the hedonic approach outweigh its disadvantages.  相似文献

The ideals and assumptions associated with a transdisciplinary approach to environmental issues are investigated through the experience of a three-year research project in KwaZulu-Natal, South Africa focused on low-cost housing. Through this work, transdisciplinarity was conceptualised not as a panacea to create an all-encompassing research approach, but as an attempt to move away from paradigm isolation and allow researchers to integrate and develop a synthesis from their separate contributions. The paper discusses aspects of transdisciplinarity including definitions, methodologies, team-building, paradigmatic rigidities, the negotiation of power in the production of knowledge with stakeholders and community partners, and institutional challenges. Trade-offs include loss of data resolution at times, but are offset by deeper understanding of the complexities and constraints of applied environmental and social research in contemporary South Africa.  相似文献

This note commemorates and celebrates the life and contribution of M. Hadi Soesastro, a Bulletin board member who passed away on 4 May 2010. Hadi was arguably Indonesia's leading public intellectual in the fields of international economic policy and political economy, ASEAN economic cooperation, and East Asian economic integration. He made seminal contributions in these fields, and on the political economy of reform in Indonesia, the economic development of East Timor, and energy economics. He also played a major role in institutional development, most notably at the Centre for Strategic and International Studies, and in many other official, academic and research endeavours in Indonesia and East Asia.  相似文献
