I examine whether incorporating economically motivated prior information yields more accurate forecasts of industry costs of equity. I find that incorporating the long‐run mean of the Capital Asset Pricing Model (CAPM) parameters and the industry characteristics in the cross section produces more accurate parameter estimates, which subsequently translate into more accurate out‐of‐sample forecasts of industry costs of equity. The outperformance of this method over rolling‐window estimates becomes larger as the forecast horizon extends into the future. These findings provide evidence that the CAPM parameters have a long‐run mean‐reversion property and correlate with the industry characteristics in a systematic way.  相似文献

We show that highly liquid Exchange‐Traded Funds (ETFs), especially those that are more liquid than their underlying basket of securities (i.e., positive relative liquidity), are particularly attractive to investors. Using three definitions of liquidity, we find that relative liquidity predicts net fund flows, as well as inflows and outflows positively and significantly. We further document a liquidity clientele among institutional investors: (i) relative liquidity is significantly more important for short‐ than for long‐term investors; and (ii) relative liquidity is inversely related to investors’ average holding duration in the ETFs. These two findings provide evidence that relative liquidity encourages short‐term demand.  相似文献

Exchange traded funds (ETFs) provide a means for investors to access assets indirectly that may be accessible at a high cost otherwise. I show that liquidity segmentation can explain the tendency for ETFs to trade at a premium to net asset value (NAV) as well as the life‐cycle pattern in premiums. ETFs with larger NAV tracking error standard deviations (TESDs) tend to trade at higher premiums and the liquidity benefits offered by foreign ETFs and fixed income ETFs are revealed to be the most valuable to investors. Further tests validate that TESD has the desirable properties of a liquidity segmentation measure.  相似文献

Built upon the agency theory and the stewardship theory, this study examines the mergers and acquisitions (M&A) activities among Chinese publicly listed firms. Using a founder-CEO indicator, we separate steward effects from agency effects, and find that Chinese firms’ M&A activities are significantly influenced by the steward factors after controlling for the agency factors. Firms, of which CEO is a founder, enjoy relatively higher premium during M&A. Further investigation reveals that the steward effects vary in the power of CEO. The results show that steward effect is reinforced when founder-CEO is more powerful.  相似文献

Ever since the publication of the Stiglitz Report, France has been heavily involved in the measurement of well‐being. The French Statistical Institute (INSEE) has expanded the scope of its existing surveys. It has also launched an innovative experimental survey which, drawing upon a single statistical source, aims for the first time to explore the different dimensions of both objective and subjective quality of life, as highlighted in the Stiglitz Report. It allows us to study, at the individual level, correlations between these dimensions and the accumulation of deprivations. It has enabled us to better understand the links between determinants generally referred to as objective dimensions of quality of life (such as health or education) and subjective well‐being. This information is of paramount importance for policy makers who cannot act directly on the level of people's satisfaction but can only act upon the levers of objective dimensions. This paper presents the main findings of the experimental survey.  相似文献

在船舶建造过程中焊接工作量约占全部的30%~40%,焊接是保证质量的重中之重。焊接质量出问题,就可能造成严重的后果。我厂沿江堤而建,空气中湿度大,工作条件差。密集性气孔很严重。所以,在这种情况下,对我厂焊接质量控制提出更高的要求。  相似文献

Correctly valuing tax shields has been a challenge in corporate valuation. A recent study by Liu (2009) introduces the slicing approach to separating the tax shield into the earned and unearned parts. Liu also shows that the MM results are wrong, and claims that the slicing approach has finally resolved the issue of pricing tax shields, thereby bringing closure to the topic. However, through careful analysis, we refute Liu’s main claims and restore the MM results. There are still open questions and the topic is not completely resolved as claimed in Liu (2009).  相似文献

I develop and calibrate an agent-based model of boundedly rational, adaptive agents in a two-good production and exchange economy to replicate human-subject outcomes in the same eight-person experimental economy. To test agents’ ability to capture human behavior, I extend the model and use its output to make predictions about a second experimental environment in which the group of eight agents is slowly constructed by merging smaller groups. This environment improves human-subject performance in the specialization and exchange task, and commensurate improvement emerges for some parameterizations of the agent-based model. This iterative process yields incremental improvement of decision-level theories about economic discovery.  相似文献
