This research shows that the ACA health insurance exchanges have generated more merger activity in the health insurance market. The impact is robust to control for an extensive set of factors suggested by both neoclassical and behavioural frameworks. The economic impact of this ACA provision is substantial with 3.8 more months of unusually high merger activity or 52 more merger bids per year. 相似文献

This article tests the Expectations Hypothesis (EH) using Brazilian monthly data for bond yields spanning the 2000–2017 sample period and ranging in maturity from 3 months to 5 years. Three tests are examined: the first is based on interest rates spread and the other two are based on the forward rates. On balance our results suggest rejection of the EH throughout the maturity spectrum examined, and are broadly consistent with previous findings that a linear combination of forward rates provides a statistically significant prediction of bond excess returns. 相似文献

We examine individual IPO betas and provide further evidence that the documented decline in IPO betas results primarily from a seasoning or information effect and not from the delisting of high beta securities. We employ stochastic coefficient regression analysis which permits the estimation of individual IPO betas at all points in time, and therefore avoids disadvantages associated with grouped cross-sectional beta estimates and average individual time-series beta estimates. We find that IPO firms with the lowest betas are more likely to delist, and that individual IPO betas, on average, decline over time which provides support for the information hypothesis. 相似文献

This paper empirically analyses for the first time the median voter hypothesis in Japan as a means of investigating whether
or not Japanese prefectural finance reflects the preference of the median voter. The hypothesis is tested by estimating the
demand functions of local public goods in each prefecture. As official data on the income of the median voter is unavailable
in Japan, respective prefectural data is constructed using official data on income distribution and taxation. Reasonable intuitive
interpretation of results indicates that the median voter hypothesis is supported in prefectural finances, and that voter
preference affects the outcome of gubernatorial elections, i.e., a governor's reelection probability, by estimating a probit
model. When considering the centralized prefectural government system in Japan, these results indicate that central government
management of prefectural expenditures via inter-regional grants ultimately reflects jurisdictional median voter preference.

行为金融学目前已逐渐成为金融学研究中的一个重要领域,在它的影响下,公司财务领域内也形成了行为公司财务的研究范式。与经典的公司财务理论相比,行为公司财务引入了行为因素的影响,它认为外部市场的非有效性和内部管理者的非理性影响着公司的财务决策和公司价值最大化的行为。文章简单总结了行为公司财务的最新研究进展,也就是市场的非有效性和管理者的非理性对公司的融资政策、投资政策、股利政策和并购行为等各方面的影响。针对目前我国资本市场的非有效性,文章认为在我国上市公司的财务研究中应该引入行为公司财务的理论范式和研究方法,才能使得研究前提和结果符合我国的实际经济情况。 相似文献

以Brown等人提出的共同基金竞赛假说为基础,通过Spearman检验考察中国开放式基金是否符合竞赛假说得出,总体来看中国开放式基金的竞赛假说并不明显,不同的年份有不同的表现;新基金比老基金表现出了更为典型的竞赛假说特征;Spearman相关系数检验表明新基金比老基金的投资策略更为稳健。 相似文献

依据2010—2020年共6期中国家庭追踪调查(CFPS)面板数据,构建个体层面就业质量指标体系,考量就业质量对家庭消费升级的影响。结果显示:就业质量显著促进家庭消费升级;与农村和中西部地区相比,就业质量提升对城镇和东部家庭消费升级的促进效应更显著;机制分析表明,金融素养水平、家庭经济条件、年龄段均存在不同程度的调节效应。 相似文献

We find that augmenting a regression of excess bond returns on the term structure of forward rates with an estimate of the mean realized jump size almost doubles the R2 of the forecasting regression. The return predictability from augmenting with the jump mean easily dominates that offered by augmenting with options-implied volatility and realized volatility from high-frequency data. In out-of-sample forecasting exercises, inclusion of the jump mean can reduce the root mean square prediction error by up to 40%. The incremental return predictability captured by the realized jump mean largely accounts for the countercyclical movements in bond risk premia. This result is consistent with the setting of an incomplete market in which the conditional distribution of excess bond returns is affected by a jump risk factor that does not lie in the span of the term structure of yields. 相似文献

ARCH and GARCH models assume either i.i.d. or ‘white noise’ as is usual in regression analysis, while also assuming memory in a conditional mean square fluctuation with stationary increments. We will show that ARCH/GARCH is inconsistent with uncorrelated increments, violating the i.i.d. and ‘white’ assumptions, and violating finance data and the efficient market hypothesis as well. 相似文献

随着民族教育的不断发展,越来越多的操民族语言的学生走入大学的校门,对该类学生的英语教学也引起了教育工作者的重视。本文以语言输入理论和情感过滤假设理论为依据论述了对该类学生进行分级教学的必要性以及实施分级教学的设想。 相似文献
