现代服务业：上海经济增长的新动力

本文通过经济增长弹性与就业弹性两个指标,对上海"十一五"规划中提出将优先发展的现代服务业及其主要子行业在上海经济增长中的作用进行了研究。分析认为目前上海第二产业与第三产业对经济的拉动力相当。而现代服务业的拉动力大于传统服务业。近年来,现代服务业的就业弹性均值较大,同时弹性的波动变化很大,这是上海GDP就业弹性近几年波动增大的主要原因。同时,通过对现代服务业中主要子行业的分析,发现现代服务业子行业间就业弹性的变动有着高度的正相关,这将增加现代服务业就业弹性波动对于上海GDP就业弹性波动的影响。     

企业并购会计处理方法的研究

伴随着市场经济的发展成熟,市场竞争日益加剧和激烈,而作为市场主体的企业欲在激烈的市场竞争中生存和发展,一般通过内部扩充和外部扩张而运行,而并购则是企业外部扩张最迅速、最典型、最重要的方式。而全球经济一体化的加速发展,中国的企业并购也愈来愈频繁。本文拟对企业并购传统会计处理方法及其新理论作初步的探讨。     

Do homeowners achieve more household wealth in the long run?

Despite the public’s faith in homeownership as a vehicle for wealth creation, there are surprisingly few empirical studies of the independent impact of homeownership and its duration on household wealth accumulation. This paper provides the first empirical evidence that homeownership, after controlling for other drivers of wealth accumulation, is positively and significantly associated with wealth accumulation over time. Using the Panel Survey of Income Dynamics, it examines the influence of housing tenure choices between 1989 and 2001 on household net wealth levels in 2001 after controlling for initial wealth in 1989, location, income, education, and other family and personal characteristics that might influence the rate of wealth accumulation. Importantly, the models used also control for the tendency of households to accumulate wealth between 1984 and 1989 (five years prior to the studied period). This approach is used to address the possibility that an unobserved variable—the propensity to save or accumulate wealth—may be associated with both the probability and duration of homeownership and the rate of wealth accumulation. All else equal, those who owned homes and owned for longer periods of time had significantly higher household net wealth by 2001. These results are compelling because house price appreciation over the period was near its long-run average while stock gains were above and real rent increases below their long-run averages. Hence, the findings are suggestive of a positive influence of ownership over long periods on net wealth, even during a period when alternative investments produced higher than normal returns and rents grew slowly. This is especially important because the overwhelmingly majority of households do not sell their homes shortly after buying them. In our sample, those who became owners typically owned for 7 years. Furthermore, most households that bought during a period of declining real home values in the early 1990s continued to own their homes for at least eight years and came out well ahead of those who did not own.
