Who Gains from the Demographic Dividend? Forecasting Income by Age

Changes in the population age structure are known to influence the total income per person, but little is known about whether the changes are equally shared across the population or are concentrated on particular age groups and/or birth cohorts. The answer to this question has potentially important implications for income inequality, human capital investment, and fertility decision-making. We propose a new model of intergenerational transfers which distinguishes between the effects of changes in population structure and the effects of changes in family age structure. Using age-specific data from annual income and expenditure surveys of Taiwan between 1978 and 1998, we show that changes in age structure have had a very favorable effect on Taiwan's income growth. The gains are not equally shared by all age groups, however. Children and young adults have benefited the most, while the elderly have benefited the least. The population and family age structures have independent effects on per capita income; the effect of the population age structure is most important. Generational differences in per capita income are closely related to intergenerational differences in earnings, suggesting only a weak form of altruism. Finally, we predict that, on average, population aging will adversely influence the per capita income growth in Taiwan in the coming decades.     

上市公司年报预约披露时间变更现象的透视

2002年年报披露情况 我国证监会规定上市公司年报披露的时间为每年1月1号至4月30号，鉴于前几年年报披露中存在的“前松后紧”的现象(即上市公司年报集中在靠近4月30号的一段时间披露)，为做好上市公司年报披露工作，从2001年年报开始沪深证交所有关部门要求上市公司在证交所指定网站上预先申报披露时间，然后按照“均衡披露”的原则，经证交所平衡和调整，     

Headship rates and the household formation process in Great Britain

"This paper looks at the changes in headship rates in Great Britain over the period 1960-1979, and attempts to explain them in terms of economic variables, such as real income and the real cost of housing. Such variables are found to be significant for some household types, but not for others. Notably, young single person household formation appears to be more supply constrained and to respond to appropriate supply variables." Furthermore, "some comparisons are made with similar studies done on similar data from the USA and France. These studies reveal a number of features in common, but also some differences, and these are commented upon."     

Waves of migration: a new situation

An attempt is made to forecast migration trends affecting those countries that were formerly part of the Soviet Union. "The new migratory trends are characterized by at least three fundamentally important elements: the ouster of the newly arrived population from the social niche that it had recently occupied, emigration from overpopulated regions, and growing emigration beyond the borders of the former Union."

地区专业化形成机制研究

传统经济学文献强调地域特有资源对区域专业化形成的影响，克鲁格曼等新经济地理学家则强调基于企业规模经济的累积过程机制，本文以马歇尔关于地方化产业形成机制的理论分析为基础，以初创企业建立及其带来的市场信息和技术知识溢出来解释区域专业化的形成。     

外资商业的进入及我国商业的应对措施

外资商业大规模进入我国有利也有弊，它影响着我国的经济安全，严重冲击了中国民族商业的生存和发展，但对中国的商业也起到了示范和带动作用。我国应进一步规范外资商业的发展，进一步做强、做大民族商业，注重加大对中小型流通企业的扶持力度，特别是要进一步加快开拓、发展和创新的步伐。
