If communities living adjacent to the elephant see it as a burden, then they cannot be its stewards. To assess their valuation of it, a contingent valuation method study was conducted for one CAMPFIRE district in Zimbabwe. Respondents were classified according to their preferences over the elephant. The median willingness to pay for the preservation of 200 elephants is ZW$260 (US$4.73) for respondents who considered the elephant a public good and ZW$137 (US$2.49) for those favouring its translocation. The preservation of 200 elephants yields an annual net worth of ZW$10,828 (US$196) to CAMPFIRE households. However, the majority of households (62%) do not support elephant preservation. This is one argument against devolution of elephant conservation. External transfers constitute one way of providing additional economic incentives to local communities. 相似文献

This study examines the exit process of Western European farmers. Using a simple theoretical model of structural change, we examine empirically the impact of farm characteristics, macroeconomic conditions and policy intervention on farm exits during the 1990s. Econometric estimates using regional data for 110 regions in Western Europe indicate that exits from farming are strongly influenced by farm characteristics and policy conditions. In particular, exit rates are higher in regions with smaller farms and are closely related to production structures. Exit rates are lower in regions with more part‐time farming, high subsidy payments and high relative price increases for agricultural outputs, indicating that off‐farm income and government intervention slow down structural change in European agriculture. 相似文献

This paper presents a case from Volvo that explores an innovative RFID solution that leverages the exiting infrastructures of mobile usage. ‘Smart goods’ is used to explain features applied through Radio Frequency IDentification, utilization of cellular networks (GSM/GPRS) and web technology together with collaboration among supply chain actors. This has reduced traditional barriers of entry. An empirical case provides the basis for evaluation from the perspectives of operational reliability, usability and productivity. 相似文献

We present an econometric analysis of wage behaviour in Norway during the interwar years. The analysis is based on a panel of manufacturing industry data using GMM estimation methods. Our empirical analysis shows that wage formation in the interwar period can be understood with the help of modern bargaining theory and well‐established wage equations. We estimate a long‐run wage curve that has all the standard features of being homogeneous in prices, proportional to productivity, and with a negative unemployment elasticity. We also present some new Monte Carlo evidence on the properties of the estimators used. 相似文献

Using contingent claims analysis, I quantify the effect of risk-reducing corporate diversification on the value of equity as a call option on firm assets. The impact of conglomeration on firm risk is heavily conditioned on firm size. In contrast to small firms, the risk of large firms does not decline with increasing conglomeration. Accounting for this effect, the expected equity discount is much lower than commonly assumed and can even turn into a premium if the path dependency of equity is incorporated. My results stand in direct contrast to those of Mansi and Reeb (2002) and caution against using asset substitution as a qualitative argument for explaining economy-wide value phenomena. 相似文献

While innovative technology supply has been the focus of much neo-Schumpeterian modelling, few have addressed the critical and more resource-demanding commercializing of the same technologies. The result may have been a growth policy focused on the wrong problem. Using Competence Bloc Theory and a firm-based macro to macro approach we abandon the assumed linear relation between technology change and economic growth of such models, and demonstrate that lack of local commercialization competences is likely to block growth even though innovative technology supplies are abundant. The break up, reorganization and part withdrawal of Pharmacia from the local Uppsala (in Sweden) economy after a series of international mergers illustrate this. Pharmacia has ‘released’ a wealth of technologies in local markets. Local commercialization competence, notably industrially competent financing has, however, not been sufficient to fill in through indigenous entrepreneurship the vacuum left by Pharmacia. Only thanks to foreign investors, attracted by Pharmacia technologies that have opted to stay for the long term, the local Uppsala economy seems to be heading for a successful future. The Pharmacia case also demonstrates the role of advanced firms as ‘technical universities’ and the nature of an experimentally organized economy (EOE) in which business mistakes are a natural learning cost for economic development. 相似文献

Conclucions The field is still wide open for all kinds of speculations about the content of future EEC discriminations against the communist countries, but so far there is very little substance to the accusations that EEC is discriminating against them. Neither strategic export controls nor credit discrimination seems to have been affected at all by the creation of EEC. On non-oil products a few individual cases of protection can be cited, and the consultation procedure may conceal some discrimination. But it is important to stress that the reasons for this discrimination are of the same protectionist nature as those behind the chicken war and other protectionist measures against USA, EFTA and other third nations. That the procedures are different-consultations and quotas against the communists and mainly tariff protection against the Western nations-is motivated more by the communist state trading system and its consequences than by special EEC policies.The only case where some EEC discrimination for non-commercial, political reasons can be suspected is for oil and oil products. The present strict mutual scrutiny of the import policies of the different member countries is likely to continue and to develop into some form of common policy, where security considerations may influence the setting of upper import limits of Soviet oil. But so long as this policy is not made official it is impossible to pinpoint any discrimination.In summary it can be said that the communist accusations, implying that EEC constitutes an endeavour to hurt the Soviet Union and the socialist camp through a discriminatory trade policy, are based more on the possibility that such a discrimination can come into existence than on any evidence that it actually has done so. These accusations are in fact very much akin to the Western exaggerations of actual Soviet economic warfare, based on the fact that the Soviet trade system indeed makes it possible to hide any kind of political warfare considerations inside the system.NOTE: The present article does not deal explicitly with economic planning problems or the socialist countries. However, we think the political problems discussed in this article are an interesting aspect of the relations between centrally planned economies and the market economies.

This note presents the following two results. First, the finite-lived American option to exchange one asset for another is transformed into a finite-lived American call, for which a large set of excellent PC-based programmes is available. And second, the finite-lived American put is transformed into acorresponding call. Thus, it is unnecessary to develop and implement a separate numerical method for the American put. 相似文献
