International capital market equilibrium is characterized for a world economy in which consumption preferences are defined multiplicatively over many commodities. It is shown that the set of relative asset prices under pure exchange in international capital markets depends on the real purchasing power of nominal payoffs under uncertainty and does not depend on the currency in which the nominal payoffs are denominated. A Sharpe-Lintner type international capital asset pricing model is derived as a special case. Proportional ad valorem commodity taxes and transportation costs are incorporated in the valuation model, interest rate parity and purchasing power parity are reinterpreted under uncertainty, and international differences in borrowing and lending are shown to reflect, in part, differences in risk aversion across countries. 相似文献

This article draws on selected findings of one of a series of surveys conducted by the authors in the Eastern Cape province, dealing broadly with labour market issues. Particular attention is accorded to levels of unemployment, the extent of migrancy, the operation of extended networks of support, and survival strategies. This is followed by a brief look at perceptions of crime, and the extent to which crime is seen as an effective survival mechanism by the most marginalised. It is concluded that economic reconstruction in the province should take account of certain prevailing realities, including the operation of extended networks of support and the relative lack of mobility of the most marginalised, the limited capacity of the informal sector to absorb further numbers of the structurally unemployed, and the relative propensity of the most marginalised to engage in crime as a survival strategy. 相似文献

This paper provides empirical estimates of the stock market reaction to tender offers, both successful and unsuccessful. The impact of the tender offer on the returns to stockholders of both bidding and target firms is examined. The evidence indicates that for the twelve months prior to the tender offer stockholders of bidding firms earn significant positive abnormal returns. In the month of the offer, only successful bidders earn significant positive abnormal returns. Stockholders of both successful and unsuccessful targe firms earn large positive abnormal returns from tender offers, and most of these returns occur in the month of the offer. For all classes of firms, there is no significant post-offer market reaction. The market reaction to ‘clean-up’ tender offers is also estimated and target stockholders again earn significant positive abnormal returns. 相似文献

Young people's relationship with the future is complex and contradictory. Some surveys and commentaries suggest most are optimistic, others that they are pessimistic. Some indicate they are adapted to the postmodern world of rapid change and uncertainty, others that they are anxious and apprehensive. Some of these differences can be readily explained; others require more thorough analysis. We need a better understanding of this relationship if we are to improve both young people's personal well-being and humanity's prospects. It may help if we distinguish between three different images—modern, postmodern and transformational. 相似文献

ABSTRACT This study examines the four commonly tested hypotheses in hydroelectricity consumption – economic growth literature for 12 Asian countries. Our results from a recently developed hidden cointegration technique uncover rich and significant relationships between negative and positive components of the variables under consideration. In particular, we find evidence to support the neutrality hypothesis in five countries (Bangladesh, Indonesia, Pakistan, Philippines, and Thailand), the growth hypothesis in four countries (India, Japan, South Korea and Taiwan), and both growth and conservation hypotheses in three countries (China, Malaysia, and New Zealand). These findings suggest that appropriate economic policies should be elaborated on the basis of the country’s specific hydroelectricity consumption–growth nexus. Finally, our new evidence suggests that the lack of stable relationship between hydroelectricity consumption and economic growth documented in previous studies for some of these countries could be due to the failure to properly account for the nonlinearity property in the data. 相似文献

AbstractBackground and aims: A wide range of treatment options are available for hepatocellular carcinoma (HCC), including systemic treatment with tyrosine kinase inhibitors (TKIs) such as sorafenib and lenvatinib, immunotherapies, locoregional therapies such as selective internal radiation therapy (SIRT) and treatments with curative intent such as resection, radiofrequency ablation and liver transplantation. Given the substantial economic burden associated with HCC treatment, the aim of the present analysis was to establish the cost of using SIRT with SIR-Spheres yttrium-90 (Y-90) resin microspheres versus TKIs from healthcare payer perspectives in France, Italy, Spain and the United Kingdom (UK).Methods: A cost model was developed to capture the costs of initial systemic treatment with sorafenib (95%) or lenvatinib (5%) versus SIRT in patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stages B and C. A nested Markov model was utilized to model transitions between progression-free survival (PFS), progression and death, in addition to transitions between subsequent treatment lines. Cost and resource use data were identified from published sources in each of the four countries.Results: Relative to TKIs, SIRT with SIR-Spheres Y-90 resin microspheres were found to be cost saving in all four country settings, with the additional costs of the microspheres and the SIRT procedure being more than offset by reductions in drug and drug administration costs, and treatment of adverse events. Across the four country settings, total cost savings with SIR-Spheres Y-90 resin microspheres fell within the range 5.4–24.9% and SIRT resulted in more patients ultimately receiving treatments with curative intent (4.6 vs. 1.4% of eligible patients).Conclusion: SIR-Spheres Y-90 resin microspheres resulted in cost savings relative to TKIs in the treatment of unresectable HCC in all four country settings, while increasing the proportion of patients who become eligible for treatments with curative intent. 相似文献

Recently General Medical Practice has been inundated with a range of financial and accountability changes. These imposed changes have been welcomed with considerable resentment by General Practitioners (GPs hereafter). This paper explores some of the key historical and contextual reasons for this resentment. The conclusion is that it is traceable to firstly, the nature of these reforms, which are seen as irrelevant at best or, at worst, run counter to the values and concerns of GPs, and secondly, and related to this, to the perceived inappropriate intrusion into medical autonomy by a Government whose forbears were previously enabling such freedom. 相似文献
