Using a sample of 85 Chilean firms listed in the Santiago Stock Exchange from 2005 to 2013, we analyze the impact of corporate diversification on firm value. We consider voting rights of the main shareholder and institutional investors’ influence on firm value. We report firm‐value destruction for diversified firms. Regarding ownership concentration, we report a negative relation between the largest shareholder ownership and firm value. Separation between voting rights and cash flows rights of this shareholder is negatively related to firm value. While Pension Fund Administrators (AFP) mitigate firm value destruction in diversified firms, other institutional investors do not play an active role in controlling value destruction. Finally, if the largest owner is a family, we report firm‐value creation in diversified firms. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd. 相似文献

Consider the standard nonparametric regression model and take as estimator the penalized least squares function. In this article, we study the trade‐off between closeness to the true function and complexity penalization of the estimator, where complexity is described by a seminorm on a class of functions. First, we present an exponential concentration inequality revealing the concentration behavior of the trade‐off of the penalized least squares estimator around a nonrandom quantity, where such quantity depends on the problem under consideration. Then, under some conditions and for the proper choice of the tuning parameter, we obtain bounds for this nonrandom quantity. We illustrate our results with some examples that include the smoothing splines estimator. 相似文献

Motor carrier safety is an important concern of shippers, carriers, policy makers, consignees, insurance providers, and the motoring public. One aspect of carrier safety that has garnered substantial attention is whether carriers making greater use of owner–operators are more or less safe vis‐à‐vis carriers making greater use of employee drivers. Currently, conflicting theoretical predictions exist regarding the direction of this relationship. In this article, we offer a reconciliation of the alternative theoretical predictions by developing a coherent theory that merges sociological rational choice theory and theory regarding motor carrier safety. We subject our theory to empirical testing by fitting a series of seemingly unrelated regression models to a vector of safety measures tracked as part of the Federal Motor Carrier Safety Administration's Compliance, Safety, and Accountability program. Our results are consistent with our proposed theory of owner—operator safety and provide meaningful theoretical and managerial implications and directions for future research. 相似文献

This paper adopts Hsiao (1986) panel data techniques, with metropolitan-level panel data from Taiwan, to examine how the market structures of various related service markets and hotels’ locations affect hotels’ profitability. The empirical results indicate that: (1) market concentration in rooms could significantly improve international tourist hotels’ profitability, while concentration in the food and beverage markets have positive but insignificant effects, and (2) the locations of the international tourist hotels significantly affect their profitability. 相似文献

管理创新是企业创新体系中一个重要的组成部分,管理创新的主体是企业经营者,因此企业经营者的人力资本状况与企业管理创新关系十分密切。本文论述了管理创新在企业创新体系中的地位与作用,对管理创新与经营者人力资本之间的关系问题进行了探讨,论述了管理创新与经营者人力资本提高之间的内在联系。 相似文献

拉普特等人用数据来表明,法律来源于普通法系国家比法律来源于大陆法系国家特别是法国大陆法系国家能更好地保护投资者,而德国大陆法系国家和斯堪的纳维亚国家则介于这二者之间。公司所有权的集中程度在他们的研究中被认为是对投资者保护差的一种适应性反映。在本文,我们用中国和其他国家的证据来说明政治经济因素比法律来源论能更好地解释在中国的转型经济中对小股东保护差的原因。我们认为中国上市公司所有权非常集中的原因是政府决策的直接结果,也认为政府控制绝大部分上市公司在某种程度上减弱了对小股东的保护。 相似文献
