We study the distribution of basic scientific research across countries and time, and explain the process that resulted in the United States becoming the undisputed leader in basic research. Our study is based on the records of scientific awards, and on the data of global economic trends. We investigate the degree to which scale/threshold effects account for the number of prizes won. We constructed a stylized model, predicting a non-linear relationship with lagged relative GDP as an important explanatory variable of a country’s share of prizes. Our empirical research findings find support for these predictions and the presence of a “winner-takes-all” effect.   相似文献

股票内在投资价值理论与中国股市泡沫问题   总被引:43,自引:0,他引:43  
股票内在投资价值理论是评估股票内在投资价值的依据。而只有准确评估了股票的内在投资价值,投资者和决策者才能正确认识股市泡沫问题。本文首先对股票内在投资价值理论做了综述,然后对目前最前沿的股票内在投资价值模型(基于帐面价值和剩余收益的F O模型)做了改进,使之更具有实用价值。接着利用改进后的F O模型,测算了中国股市目前的内在投资价值以及中国股市泡沫的绝对规模和相对规模。计算表明,与2 0 0 1年6月份股市高峰期相比,2 0 0 4年底中国股市泡沫的绝对规模和相对规模都已大幅度下降。文章最后提出了几点政策建议。  相似文献

智力劳动的分配决定效应及模型   总被引:17,自引:0,他引:17  
随着知识的积累与科技的进步 ,智力密集型劳动已经替代体力密集型劳动成为价值的最主要源泉。智力劳动的特征使得凝结在产品中的劳动含量与智力投资呈正相关 ,进而与其所形成的智力劳动力价值呈正向相关。因此 ,提高智力劳动力价值在分配决定机制中的权重 ,相对于现行以工龄为主体的工资决定体制而言 ,更能体现按“能”付酬原则 ,更能体现生产力的进步对分配的决定作用。以简单劳动力价值确定最低工资水平 ,然后依据每一阶次的智力劳动力价值差别确定工资水平差别 ,更能推动智力投资与劳动力资源的合理配置。以智力劳动力价值为基础的工资分配制度 ,可界定为一个基于贴现理论的微观静态分配模型。  相似文献

综合与分类相结合的个人所得税制改变了个人所得税按来源地缴纳和分享的模式。个人综合所得的所得税征收时实行预扣预缴和次年汇算清缴制度。当个人综合所得来源于多个地区时,需要在不同预扣预缴地区间进行汇算清缴。如何在不同收入来源地分配税收成为地区间汇算清缴制度设计的重要关键。本文首次从税收创造和税后收益分配角度,建立了两个税收分配的合作博弈模型。比较分析发现,使用解决"破产问题"的方法都是把地区的所得和总税收作为给定的参数,没有考虑地区所得和税收之间的生成关系和累进税率。我们的研究证明夏普利值作为合作博弈的解,具有公平性、效率性和单调性,是个人所得税地区间分配方式的合适选择。  相似文献

The starting-point of the present paper are systematic differences between the answers of German corporate managers and professors in an empirical study by C&L Deutsche Revision AG (1995) on accounting harmonization. In this study, managers expressed themselves in all questions more positively towards current German accounting and more negatively towards US accounting than professors. The fundamental assumption put forward in this paper is that these differences are due to differences in the economic interests of the two groups. To test this empirically, hypotheses are deduced with regard to the accounting-related interests of the executive managers. The idea behind the hypotheses is that managers' answers to questions in the C&L Industry Study can be explained by structural features of their respective companies. The hypotheses are tested using multiple regression analysis. The results of the tests show that managers' answers can, to some extent, be explained by the suggested multiple regression approach. However, the answers to the rather general and abstract question (the preferred balance between the true-and-fair-view and prudence accounting principles) are much better explained than the answers with regard to detailed US-GAAP regulations. We must assume that the managers' attitudes towards concrete US-GAAP, which are directly related to corporate accounting practice, are influenced by a multitude of firm-specific and personal factors.  相似文献

Sources of gains from international portfolio diversification   总被引:1,自引:0,他引:1  
This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of forty eight countries and thirty nine industries over the last three decades. Country factors have remained relatively stable over the sample period while industry factors have significantly increased during the last decade and dropped again since 2000. The importance of industry and country factors is correlated with measures of economic and financial international integration and development. We find that financial market globalization is the main driving force behind the changes in relative magnitude of the different shocks. Country factors are smaller for countries integrated in world financial markets and have declined as the degree of financial integration and the number of countries pursuing financial liberalization has increased. Higher international financial integration within an industry increases the importance of industry factors in explaining returns. Economic integration of production also helps in explaining returns. Countries with a more specialized production activity have higher country shocks.  相似文献

Among the growing literature on value creation in collaborative buyer-seller relationships, most researchers examine relationship value at a single point in time. In the present research, we explore whether different stages of the relationship life cycle moderate the relative importance of value-creating dimensions. To shed light on the dynamic nature of value in B2B relationships, we present the results of a survey among purchasing managers using a quasi-longitudinal research design. Our findings confirm the moderating role of the relationship life cycle in value creation. More precisely, our results indicate that a key supplier's potential for value creation in customer's operations increases in relative importance as relationships move through the life cycle. In turn, supplier's capabilities to create superior value at the level of the customer's sourcing process display a decreasing role over the life cycle of a business relationship. No significant link was found in the present study between value creation through a supplier's core offering and different stages of a buyer-seller relationship.  相似文献
