Internally‐promoted CEOs should have a deep understanding of their firm's products, supply chain, operations, business climate, corporate culture, and how to navigate among employees to get the information they need. Thus, we argue that internally‐promoted CEOs are likely to produce higher quality disclosure than outsider CEOs. Using a sample of US firms from the S&P1500 index from 2001 to 2011, we hand‐collect whether a CEO is hired from inside the firm and, if so, the number of years they worked at the firm before becoming CEO. We then examine whether managers with more internal experience issue higher quality disclosures and offer three main findings. First, CEOs with more internal experience are more likely to issue voluntary earnings forecasts than those managers with less internal experience as well as those managers hired from outside the firm. Second, CEOs with more internal experience issue more accurate earnings forecasts than those managers with less internal experience as well as those managers hired from outside the firm. Finally, investors react more strongly to forecasts issued by insider CEOs than to those issued by outsider CEOs. In additional analysis, we find no evidence that these results extend to mandatory reporting quality (i.e., accruals quality, restatements, or internal control weaknesses), perhaps because mandatory disclosure is subjected to heavy oversight by the board of directors, auditors, and regulators. Overall, our findings suggest that when managers have work experience with the firm prior to becoming the CEO, the firm's voluntary disclosure is of higher quality.  相似文献

Research Summary : This study analyzes how the divestitures that are impelled by activist investors in their campaigns against public corporations affect shareholder value. Using hand‐collected data on the activist campaigns that were launched against and the divestitures that were undertaken by Fortune 500 companies between 2007 and 2015, we find that activist‐impelled divestitures are more positively associated with immediate and longer‐term measures of shareholder value than comparable manager‐led divestitures. These performance differences persist for nearly two years after the completion of these deals. Our results empirically test the idea that firms with agency problems unlock shareholder value when they divest, and support the notion that activist investors fulfill an important external governance function. Our work also opens new research opportunities and offers practical implications as well. Managerial Summary : This study investigates how divestitures that are undertaken at the behest of activist investors affect shareholder value. We find that divestitures that were undertaken under pressure from activist investors are associated with more positive shareholder returns than comparable divestitures that were undertaken voluntarily by managers. These performance differences persist for nearly two years after the completion of these deals, alleviating concerns about the purported short‐termism of activist investors. Our findings suggest that activist investors may fulfill an important governance function by inducing managers to undertake strategies that they might not otherwise pursue, thereby unlocking shareholder value.  相似文献

Major tax reform to simplify the UK tax system is possible. Merging income taxes, social security taxes and corporation tax into only a single flat-rate of tax on all incomes would be a radical start. Avoiding taxes on income and expenditure which are 'too high' requires major reductions in government spending, mainly on the welfare state. Given the political will, over a period of years we really can hugely improve the UK tax system.  相似文献

This article examines the demographic and geographical importance of wealthy middle-class women. It argues that in certain towns and cities, notably London, such women were of sufficient importance to merit attention in their own right. Drawing upon a sample of wills, it describes the types of wealth owned by these women. By examining women's investment in government securities, it argues that women's wealth was of crucial importance to the British state. Its findings challenge conventional understandings of the relationships between gender ideology, wealth holding, and economic development.  相似文献

Political pressure exists for the bus industry to be brought under local authority control by means of 'Quality Contracts.'These would take away from management the freedom for marketing, and especially for marketing by price, that was returned to them by the 'deregulation' of 1985. The proposed franchises would return the industry to the 'bad old days' and prevent its continued improvement through market forces from taking place. The Department of Transport considered the idea of franchises in 1985, but concluded that it would merely lead to monopoly power.  相似文献

Previous work shows that establishments with higher proportions of women are more likely to use piece rates but that individual women are less likely to receive performance pay. We present a model in which lower expected tenure and labor force attachment are positively associated with piece rates but are negatively associated with other forms of performance pay. Analysis of the National Longitudinal Survey of Youth (NLSY) confirms that women are more likely to be paid piece rates and simultaneously less likely to be paid commissions and bonuses.  相似文献

The paper examines the relationship between transitory terms‐of‐trade shocks and private saving. Using a model allowing for nonseparability between the consumption of tradables and nontradables, the paper estimates the intertemporal elasticity of substitution while accounting for the intratemporal elasticity of substitution between the consumption of tradables and nontradables. Empirical analysis of data for five industrial countries indicates that in response to transitory terms‐of‐trade shocks, intertemporal substitution of consumption and intratemporal substitution of consumption between tradables and nontradables both have large effects on private saving.  相似文献
