用马斯洛需求层次理论对“炫耀经济”的分析

一、“炫耀经济”的由来。自从凡勃伦在1899年出版了《有闲阶级论》以来，“炫耀消费”逐渐引起了社会的注意，“炫耀消费理论”从而也慢慢发展起来，而如今为满足“炫耀”这一心理需求而进行的生产、服务等各种经济活动越来越多，于是“炫耀经济”就这样形成了。凡勃伦认为，用有意脱离生产活动来表现自己拥有财富和权力的有闲阶级的消费就是炫耀消费。他把炫耀消费定义为这样一种类型的社会行为，即通过消费让他人明了消费者的金钱力量、

城市经济功能变迁中的城市交通和城市环境

农业社会的城市、产业社会的城市发展到现代社会的世界城市,城市功能也由最初的剩余管理、生产转变为生产者服务,生产的国际化和信息化使世界城市的空间和阶层出现分极化,而目前许多城市的交通、城市环境不能满足世界城市功能的发挥,追求城市的可持续发展是解决这一矛盾的根本途径。

The disparity between long-term and short-term forecasted earnings growth

We find the disparity between long-term and short-term analyst forecasted earnings growth is a robust predictor of future returns and long-term analyst forecast errors. After adjusting for industry characteristics, stocks whose long-term earnings growth forecasts are far above or far below their implied short-term forecasts for earnings growth have negative and positive subsequent risk-adjusted returns along with downward and upward revisions in long-term forecasted earnings growth, respectively. Additional results indicate that investor inattention toward firm-level changes in long-term earnings growth is responsible for these risk-adjusted returns.

The crowding-out effect of elderly support expenditure on household consumption from the perspective of population aging: Evidence from China

The pace of aging in China is accelerating, from the introduction of family planning to the liberalization of the two-child policy, with a growing proportion of families in the 4–2-1 structure. With filial piety in mind, most adult children will live with their elderly parents and share income and expenditure. Concurrently, due to the inadequacy of the social security system, a heavy supplementary burden of supporting the elderly has been placed on adult children. Based on data from the 2011, 2013, 2015, and 2017 Chinese Social Survey (CSS) of the Chinese Academy of Social Sciences (CASS), this study analyzes the objective factors affecting household elderly support expenditure using the ordinary least squares (OLS) estimation method. It also examines the crowding-out effect of elderly support expenditure on the consumption of different types of households through a panel generalized method of moments (GMM) approach. Finally, the crowding-out effect of elderly support expenditure is discussed in a sub-sample according to the number of households needing to support the elderly aged 60 and above. The empirical results illustrate that there is a crowding-out effect of elderly support expenditure on household consumption, and the magnitude of the crowding-out effect varies for diverse consumption. Our study reveals that the crowding-out effect of elderly support expenditure on core consumption is the largest in a sample with different numbers of elderly persons in families. The empirical results for the sub-sample show that the larger the elderly population, the stronger the crowding-out effect of elderly support expenditure on core consumption and the less pronounced the effect on marginal consumption.
