In little more than a century life expectancy has doubled in most parts of the world. Neither facts nor theory support the view that this Mortality Revolution is due to the Industrial Revolution and the era of rapid economic growth that ensued. Rather, both revolutions mark the onset of accelerated and sustained technological change in their respective areas. They occur largely independently of each other, the later occurrence of the Mortality Revolution being due to the later development of biomedical vis-a-vis physical knowledge. Comparative study of the two should prove fruitful. Although entrepreneurship is important in each, there appear to be differences in the underlying motivations and the role of private property and other institutions. Links between technological change, on the one hand, and scale of operation, capital inputs, and education, on the other, also offer promising possibilities for comparative study.The author is grateful to Donna Hokoda Ebata and Christine M. Schaeffer for excellent assistance, the University of Southern California for financial support, and to Eileen M. Crimmins, Samuel H. Preston, Morton O. Schapiro, Roger S. Schofield, and two referees for helpful comments.  相似文献

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.   相似文献

The search for an appropriate methodology to investigate the relation between R&D investment, knowledge stock and productivity growth is the main purpose of the paper. In analogy with physical assets, we present a model of knowledge capital formation which allows the calculation of the relevant user cost, as well. The proposed model accumulates R&D investment based on a stochastic gestation lag and a geometric depreciation of the stock. The basic parameters underlying the lag structure differ according to the types of research expenditure. The approach is applied to public R&D investment in Italian agriculture; the results provide interesting information about the economic structure of public research effort in Italian agriculture and plausible estimates of its internal rate of return.  相似文献

Within a production function framework in which government spending produces public goods which enter firms production functions, empirical tests using time series data spanning eleven countries and thirty industries find both the scale and the composition of government consumption spending to affect the level and the rate of growth of total factor productivity at the industry level.Jel Classification: H50, D24  相似文献

论平衡记分卡的"不平衡"   总被引:2,自引:0,他引:2  
国内对平衡记分卡的认识,与发达国家相比还存在很大差距。许多人还没有真正认识到平衡记分卡的含义和用法,仅仅追求形式,使平衡记分卡成为组织"看起来好看,用起来无用的装饰品"。本文提出根据企业实际情况建立精简的"不平衡"记分卡的观点,借以与大家进行深入讨论。  相似文献

在各类《统计学》教科书中,对数量指标和质量指标概念的解释不大一样,但基本的含义却是相同的。两者从概念上区别并不困难,也容易理解,但在对一些特殊问题的分析时,却不易把握,特别是在比较复杂的统计分析中,那就更不容易做出准确的判断了。怎样才能对数量指标和质量指标的应用做出科学的评价和分析。本文拟就这方面的问题做些初步探索。  相似文献

Summary. We construct an OLG model with network effects to examine skill obsolescence when individuals can choose technological vintages. In the absence of transfer payments, some regions of the parameter space have unique stationary equilibria, others have unique cyclical equilibria, and others have multiple stationary equilibria. All equilibria are Pareto efficient. However, rat race equilibria can exist in which all agents currently alive prefer a slower rate of progress than occurs in equilibrium. When contemporaneous transfers are allowed, equilibria are unique everywhere, but a cycle still exists, and a rat race can still arise in equilibrium. Allowing intertemporal transfers (debt) ensures that all equilibria are stationary. In the relevant parameter range, the introduction of debt can eliminate cycles and increase the long-run growth rate. No rat race equilibria exist when debt is allowed.Received: 3 January 2002, Revised: 3 June 2004, JEL Classification Numbers: 041, J24, O33. Correspondence to: Ian P.

经济增长、收入分配对农村贫困变动的影响   总被引:15,自引:0,他引:15  
文章利用了基于Lorenz曲线进行贫困测度及其分解的方法,实证研究了1985~2003年中国农村的贫困变动,以及经济增长和收入分配对贫困变动的影响.结果表明,经济增长使农村居民收入增加,大幅度减少了贫困,但农村居民的收入差距逐渐拉大,收入不平等加剧部分地抵消了经济增长的减贫成效.  相似文献

不确定环境下的企业战略设计模式   总被引:1,自引:0,他引:1  
本文通过对传统企业战略设计模式的再思考 ,并从企业战略设计的实际情况出发提出 :当企业面对不确定环境时 ,战略思维方式应该从线性向非线性转变 ,从而提高企业战略在不确定环境下的“预见”力和应变能力。本文建立了一个基于战略转换的战略形成、实施同步并行的企业战略设计模式 ,来达到在复杂、不确定的环境中获取持续竞争优势的目的。  相似文献
