资产价格泡沫与我国货币政策传导效应的非对称性研究

本文通过构造含有资产价格泡沫的经济系统,使用结构向量自回归模型与脉冲响应函数分析了我国货币政策对资产泡沫的影响和资产价格泡沫与其它变量之间的关系。结果表明,我国货币政策的资产价格传导渠道效应显著存在,但货币政策的资产价格效应对于不同资产类型具有非对称性,货币政策对股票市场的影响要远远大于对房地产市场的影响;资产价格泡沫的正向冲击对通货膨胀呈现出倒U型影响,并且不同资产类型对通货膨胀具有非对称性,股票市场对通货膨胀的影响要远远大于房地产市场;资产价格泡沫对产出具有正向效应,但不同资产价格类型对于产出冲击也存在非对称性,股票资产价格对产出的影响要小于房地产对产出的影响。     

Welfare effects of bubbles in an endogenous growth model

This paper examines welfare effects of asset bubbles in an endogenous growth model with overlapping generations. In our model, a steady-state equilibrium with bubbles exists only if the presence of bubbles raises the welfare level of the initial generation. Bubbles can be beneficial to generations born at relatively early dates, whereas they reduce the welfare level of sufficiently distant future generations. Increasing the rate of supply of the useless asset improves the lifetime utilities of future generations.     

日本资产价格泡沫发生机制研究

资金和投资意愿是产生资产价格泡沫的充分必要条件。20世纪80年代后期,滞后的金融体制改革、歪曲的税制、日美贸易摩擦、削减赤字的财政再建计划、良好的经济状况和国家竞争力的整体上升使日本同时具备了资产价格泡沫发生的两个条件。借鉴日本的经验,通过财政、税收政策扩大市场上可投资资产的供给,同时降低预期的投资收益是防止和缓解我国发生资产价格泡沫的主要手段。     

我国合理市盈率与股市泡沫的实证分析

市盈率是被广泛用来测量股市泡沫风险的一个重要指标。本根据“股票的理论价格应该是未来各期红利的贴现之和”这一传统金融理论，导出用以衡量股市泡沫成分的基准——合理市盈率的计算方法。通过分析发现市盈率的合理值是一个动态值，据此测量出的上海A股市场泡沫成分自1993年以来呈明显下降趋势，说明我国股票市场上的投资日趋成熟，投资行为日趋理性。     

Robust asset prices with bubbles

We generally establish equilibrium asset prices than can include price bubbles yet (a) be robust to truncations of the economy and (b) exclude trade in non-consumables, like money, stock certificates, or land deeds.     

Sectoral bubbles,misallocation, and endogenous growth

Stock price bubbles are often on productive assets and occur in a sector of the economy. In addition, their occurrence is often accompanied by credit booms. Incorporating these features, we provide a two-sector endogenous growth model with credit-driven stock price bubbles. Bubbles have a credit easing effect in that they relax collateral constraints and improve investment efficiency. Sectoral bubbles also have a capital reallocation effect in the sense that bubbles in a sector attract more capital to be reallocated to that sector. Their impact on economic growth depends on the interplay between these two effects. Bubbles may misallocate resources across sectors and reduce welfare.     

Double Bubbles in Assets Markets With Multiple Generations

We construct an asset market in a finite horizon overlapping-generations environment. Subjects are tested for comprehension of their fundamental value exchange environment and then reminded during each of 25 periods of the environment's declining new value. We observe price bubbles forming when new generations enter the market with additional liquidity and bursting as old generations exit the market and withdrawing cash. The entry and exit of traders in the market creates an M shaped double bubble price path over the life of the traded asset. This finding is significant in documenting that bubbles can reoccur within one extended trading horizon and, consistent with previous cross-subject comparisons, shows how fluctuations in market liquidity influence price paths. We also find that trading experience leads to price expectations that incorporate fundamental value.     

台湾资产价格泡沫的成因、影响及相关政策评析

如何通过相关政策控制和应对资产价格泡沫的膨胀与破裂是金融研究的热点问题。台湾股票市场曾经出现举世罕见的资产价格泡沫,为相关研究提供了很好的案例。本文深入分析台湾股市发展史上三次资产价格泡沫的成因与影响,归纳台湾当局应对股市泡沫的政策及效果,总结台湾当局干预股市泡沫时应有的立场、强度及策略。     

基于West模型的房地产泡沫的实证研究--以北京、上海、深圳为例

本文简要回顾了关于房地产泡沫的研究框架,在West模型的基础上,运用房地产合理价格是租金资本化的原理,对北京、上海和深圳的房地产市场是否存在泡沫作了实证检验.结果表明:北京住宅市场、上海住宅市场以及深圳写字楼市场在样本期内的检验结果拒绝原假设,即市场存在着泡沫现象;北京写字楼市场、上海写字楼市场和深圳住宅市场检验结果为接受原假设,即不能判断市场存在泡沫现象.本文提出了一些政策建议.
