We compare the governance of foreign firms to the governance of similar U.S. firms. Using an index of firm governance attributes, we find that, on average, foreign firms have worse governance than matching U.S. firms. Roughly 8% of foreign firms have better governance than comparable U.S. firms. The majority of these firms are either in the U.K. or in Canada. When we define a firm's governance gap as the difference between the quality of its governance and the governance of a comparable U.S. firm, we find that the value of foreign firms increases with the governance gap. This result suggests that firms are rewarded by the markets for having better governance than their U.S. peers. It is therefore not the case that foreign firms are better off simply mimicking the governance of comparable U.S. firms. Among the individual governance attributes considered, we find that firms with board and audit committee independence are valued more. In contrast, other attributes, such as the separation of the chairman of the board and of the CEO functions, do not appear to be associated with higher shareholder wealth.
我们将外国公司的治理与类似的美国公司的治理进行比较。使用公司治理属性指数,我们发现,平均而言,外国公司的治理比匹配的美国公司更差。大约8%的外国公司治理水平好于同类美国公司。这些公司大多在英国或加拿大。当我们将公司治理差距定义为其治理质量与可比美国公司治理质量之间的差异时,我们发现外国公司的价值随着治理差距而增加。这一结果表明,与美国同行相比,拥有更好治理的公司会得到市场的奖励。因此,并不是说外国公司仅仅模仿可比的美国公司的治理就会更好。在考虑的个人治理属性中,我们发现董事会和审计委员会独立的公司更受重视。相比之下,其他属性,如董事长和首席执行官职能的分离,似乎与更高的股东财富无关。

Corporate and Government Bond Funds: An Analysis of Investment Style, Performance, and Cash Flows 公司和政府债券基金:投资风格、绩效和现金流分析
Pub Date : 2006-09-11 DOI: 10.2139/ssrn.929490
George Comer, Javier Rodríguez
We examine four separate classifications (high quality corporate, general corporate, government Treasury, and general government) of investment grade bond funds over the 1994-2004 period. We verify that distinct differences exist in investment styles across the classifications. We also document significant differences in performance as corporate funds outperform government funds on a risk adjusted basis. The performance results are robust to alternative evaluation metrics. An examination of cash flows to the funds indicates that bond fund investors are aware of the performance difference and have directed their investment dollars accordingly.
我们研究了1994-2004年期间投资级债券基金的四个独立类别(高质量公司、一般公司、政府财政部和一般政府)。我们验证了不同类别的投资风格存在明显差异。我们还记录了公司基金在风险调整基础上优于政府基金的显著表现差异。性能结果对其他评估指标具有鲁棒性。对基金现金流量的检查表明,债券基金投资者意识到业绩差异,并相应地指导他们的投资资金。

Idiosyncratic Volatility and the Cross-Section of Expected Returns 特质波动率与预期收益的横截面
Pub Date : 2005-12-01 DOI: 10.2139/ssrn.886717
Turan G. Bali, Nusret Cakici
This paper examines the cross-sectional relation between idiosyncratic volatility and expected stock returns. The results indicate that (i) data frequency used to estimate idiosyncratic volatility, (ii) weighting scheme used to compute average portfolio returns, (iii) breakpoints utilized to sort stocks into quintile portfolios, and (iv) using a screen for size, price and liquidity play a critical role in determining the existence and significance of a relation between idiosyncratic risk and the cross-section of expected returns. Portfolio-level analyses based on two different measures of idiosyncratic volatility (estimated using daily and monthly data), three weighting schemes (value-weighted, equal-weighted, inverse-volatility-weighted), three breakpoints (CRSP, NYSE, equal-market-share), and two different samples (NYSE/AMEX/NASDAQ and NYSE) indicate that there is no robust, significant relation between idiosyncratic volatility and expected returns.
本文研究了特质波动率与股票预期收益之间的横截面关系。结果表明:(i)用于估计特质波动率的数据频率,(ii)用于计算平均投资组合收益的加权方案,(iii)用于将股票分类为五分位数投资组合的断点,以及(iv)使用屏幕大小,价格和流动性在确定特质风险与预期收益横截面之间关系的存在性和重要性方面发挥了关键作用。基于两种不同的特殊波动率度量(使用每日和月度数据估计),三种加权方案(价值加权,等加权,逆波动率加权),三个breakpoints (CRSP, NYSE,等市场份额)和两个不同的样本(NYSE/AMEX/NASDAQ和NYSE)的投资组合水平分析表明,特殊波动率与预期收益之间没有稳健的显著关系。

Do Firms in Countries with Poor Protection of Investor Rights Hold More Cash? 投资者权利保护较差的国家的公司是否持有更多现金?
Pub Date : 2003-11-01 DOI: 10.2139/ssrn.476442
Lee Pinkowitz, Rohan Williamson, René M. Stulz
Managers make different decisions in countries with poor protection of investor rights and poor financial development. One possible explanation is that shareholder-wealth maximizing managers face different tradeoffs in such countries (the tradeoff theory). Alternatively, firms in such countries are less likely to be managed for the benefit of shareholders because the poor protection of investor rights makes it easier for management and controlling shareholders to appropriate corporate resources for their own benefit (the agency costs theory). Holdings of liquid assets by firms across countries are consistent with Keynes' transaction and precautionary demand for money theories. Firms in countries with greater GDP per capita hold more cash as predicted. Controlling for economic development, firms in countries with more risk and with poor protection of investor rights hold more cash. The tradeoff theory and the agency costs theory can both explain holdings of liquid assets across countries. However, the fact that a dollar of cash is worth less than $0.65 to the minority shareholders of firms in such countries but worth approximately $1 in countries with good protection of investor rights and high financial development is only consistent with the agency costs theory.
在投资者权利保护不力和金融发展不佳的国家,管理者做出不同的决策。一种可能的解释是,股东财富最大化的管理者在这些国家面临着不同的权衡(权衡理论)。或者,这些国家的公司不太可能为股东的利益而进行管理,因为对投资者权利的保护不力使得管理层和控股股东更容易为自己的利益挪用公司资源(代理成本理论)。各国企业持有的流动资产与凯恩斯的交易和预防性货币需求理论是一致的。正如预测的那样,人均GDP高的国家的公司持有更多的现金。考虑到经济发展的因素,在风险更大、投资者权利保护不力的国家,公司持有更多的现金。权衡理论和代理成本理论都可以解释各国间流动资产的持有情况。然而,在这些国家,一美元现金对公司的少数股东的价值不到0.65美元,而在投资者权利保护良好、金融发展程度高的国家,一美元现金的价值约为1美元,这一事实只与代理成本理论相一致。

Institutional Allocation in Initial Public Offerings: Empirical Evidence 首次公开发行中的机构配置:经验证据
Pub Date : 2002-02-01 DOI: 10.2139/ssrn.285141
Reena Aggarwal, N. Prabhala, M. Puri
We analyze institutional allocation in initial public offerings (IPOs) using a new dataset of US offerings between 1997 and 1998. We document a positive relationship between institutional allocation and day one IPO returns. This is partly explained by the practice of giving institutions more shares in IPOs with strong pre-market demand, consistent with book-building theories. However, institutional allocation also contains private information about first-day IPO returns not reflected in pre-market demand and other public information. Our evidence supports book-building theories of IPO underpricing, but suggests that institutional allocation in underpriced issues is in excess of that explained by book-building alone.
我们使用1997年至1998年美国新股发行的新数据集分析了首次公开发行(ipo)中的机构配置。我们记录了机构配置与IPO首日回报率之间的正相关关系。这在一定程度上可以解释为,在上市前需求强劲的ipo中,给予机构更多股份的做法,与簿记理论相一致。然而,机构配置也包含了未反映在上市前需求和其他公开信息中的IPO首日回报的私人信息。我们的证据支持IPO定价过低的簿记理论,但表明机构在定价过低的问题上的配置超出了单靠簿记解释的范围。

The Second Exchange: Managing Customer Information in Marketing Relationships 第二次交流:在营销关系中管理客户信息
Pub Date : 1998-07-27 DOI: 10.2139/SSRN.2621796
M. Culnan, Sandra J. Milberg
The paper introduces the concept of the second exchange in customer relationships that is distinct from the first exchange of goods or services. The second exchange is based on the information consumers disclose in the course of a marketing transaction where personal information is exchanged for benefits derived from the use of the information. Propositions developed from our model demonstrate how strategically managing the benefits and risks (invasion of privacy) of this exchange process can impact customer acquisition and retention and thus, the firm's bottom line.
本文介绍了顾客关系中第二次交换的概念,它不同于商品或服务的第一次交换。第二次交换是基于消费者在营销交易过程中披露的信息,交换个人信息以获得使用该信息所产生的利益。从我们的模型中发展出来的命题表明,从战略上管理这种交换过程的利益和风险(侵犯隐私)如何影响客户获取和保留,从而影响公司的底线。

The Accrual Anomaly and Operating Cash Flows: Evidence from Accrual Components 权责发生制异常与经营性现金流量:来自权责发生制构成部分的证据
Pub Date : 1900-01-01 DOI: 10.2139/ssrn.892250
Zhaoyang Gu, Prem C. Jain
We argue and show that aggregation of accrual components (changes in inventories, changes in accounts payable, changes in accounts receivable and depreciation expense) into total accruals results in a loss of mispricing-related information in individual accrual components. This motivates us to examine whether the recent evidence that operating cash flows subsume the mispricing effect associated with total accruals holds when accruals are disaggregated into accrual components. We find that accrual components are associated with future abnormal returns even after controlling for operating cash flows and growth. The three-day earnings announcement period abnormal returns also support the finding. The evidence with respect to change in accounts payable is especially noteworthy because its inclusion in total accruals reduces the mispricing effects of other components considerably. Overall, the prior evidence that operating cash flows subsume the mispricing effects associated with total accruals is likely caused by the aggregation of accrual components into total accruals. Future research would benefit from focusing on accrual components rather than total accruals.
我们论证并表明,将应计组成部分(存货变动、应付账款变动、应收账款变动和折旧费用)汇总到应计项目总额中,会导致个别应计组成部分中与错误定价相关的信息丢失。这促使我们研究,当应计项目分解为应计项目组成部分时,最近关于经营性现金流量包含与应计项目总额相关的错误定价效应的证据是否成立。我们发现,即使在控制了经营性现金流量和增长之后,应计组成部分也与未来的异常回报有关。三天财报公布期的异常回报也支持了这一发现。关于应付账款变动的证据尤其值得注意,因为将应付账款计入应计总额大大减少了其他组成部分的错误定价影响。总的来说,先前的证据表明,经营性现金流量包含了与应计总额相关的错误定价效应,这可能是由应计总额组成部分的汇总引起的。未来的研究将受益于关注应计组成部分而不是应计总额。
