我国封闭式基金折价与基金运行绩效的相关性检验

笔者以我国的封闭式基金为样本,利用面板数据建模,综合考量了基金折价率与基金绩效指标间相关关系.研究结果发现,基金绩效指标对当期折价指标有显著的负的影响;而当期的基金折价指标不能准确预测未来绩效水平,即基金折价率并没有提供对未来基金绩效的有价值信息.

Determinants of Inflow to Mutual Funds: Criterion and Methodology for Their Application to the Mainland China Market

This study is based on the Froot, O’Connell, and Seasholes [2001] and Hsieh, Yang and Yu [2008] as foundations to study which reasons and control factors cause herding behavior of mutual fund inflows. The study uses the most popular Asian emerging market, China, as the sample to determine the real attractive reason behind the mutual fund inflows to China. The significant determinant of the mutual fund inflows to China is stock returns for both Shanghai and Shenzhen A stock markets.

Private equity characteristics and performance: An analysis of North American venture capital and buyout funds

The paper investigates the relationship between fund performance and fund characteristics of North American private equity (PE) funds, by analyzing the interactions of fund size, fund sequence, and past fund performance on traditional fund return measures. The empirical evidence is based on both linear and polynomial regressions, on a sample of 345 venture capital (VC) and 411 buyout (BO) funds with vintage year over the period 1995–2010. We document a concave relationship between fund size and performance, persistence in PE performance, as well as a convex relationship between fund sequence and performance. We suggest both the optimal fund size and the optimal fund sequence number. Economic implications for investors and general partners are discussed as well.     

The optimal portfolio for the two-pillar mandatory pension system: the case of Poland

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying.     

Pensions reforms,workforce ageing and firm-provided welfare

This paper investigates the impact of an exogenous increase in the legal retirement age on the firms’ propensity to provide welfare services voluntarily to their employees. To this purpose we exploit a unique information derived from the Rilevazione su Imprese e Lavoro (RIL), a survey conducted in 2015 on a large and representative sample of Italian firms. Applying different regression models we show that firms which were forced to give up previously planned hirings because of the Law 201/2011 (the so-called ‘Fornero pension reform’), increased the probability of providing welfare services at workplace. By referring to the sociological, human resource management and economic literature we then argue that a sudden increase in the legal retirement age may motivate the employers to establish welfare schemes as a way to cope with an ageing workforce. Our findings also hold when propensity score matching methods are used in order to control for sample selection issues.     

基于风格调整的开放式基金业绩评价实证研究

基金的投资风格对于基金业绩有重大影响,将不同投资风格的基金业绩直接进行对比,不能科学地体现基金表现的优劣。本文以2005年4月1日到2009年11月30日期间经历了一个完整的上涨和下跌行情的我国51只开放式股票型基金为样本,运用Fama-French三因素模型对基金的投资风格进行检验,并在剔除风格因素后对基金业绩进行评价,结果发现我国开放式股票型基金投资风格严重趋同,表现为大盘成长型。经过风格调整之后,基金取得了一定的超额收益。     

论降低缴费率对养老金给付的影响——基于现收现付制度的视角

在现收现付制中,当前养老金缴费的减少对养老金的给付不一定有消极的影响。由于养老金的给付水平取决于资本份额的分配和跨主观贴现因子,利用简化的戴蒙德的叠代模型证明,当生产资本权重较高和主观贴现因子较低时,当前年轻一代缴费率的减少会提高养老金的给付水平。
