We investigate the potential costs and benefits of firms constituting a heterogeneous pool of directors relative to more homogeneous boards. We measure director heterogeneity along six separate dimensions and divide board heterogeneity into occupational and social components. Our empirical analysis indicates that corporate complexity and managerial control exhibit significant influence on board heterogeneity. Using the heterogeneity of the county population of the firm's headquarters as an instrument, we also find that investors place valuation premiums on heterogeneous boards in complex firms but discount heterogeneity in less complex firms. Overall, our analysis indicates greater heterogeneity may not necessarily improve board efficacy. 相似文献

The debate over the use of tariffs or value added taxes in developing countries has focused on the difficulty of collecting
VAT from the informal sector. This paper contributes by considering this issue with heterogeneous firms and endogenous entry.
This yields two results. First, a cut in the tariff reduces the size of the informal sector. Second, the imposition of VAT
need not increase the size of the informal sector. Turning to simulation results, we find that switching from a tariff to
a revenue-neutral VAT increases welfare, in part because of the selection effect generated by heterogeneous firms. 相似文献

This research addressed the questions: do audit committees (AC) in Victorian local government function effectively? Qualitative and quantitative data were collected to measure the perceptions, attitudes and perspectives of mayors, chief executives and chairs of the AC. The results were compared with perceptions of committee members of the Local Government and Shires Association of New South Wales and board members of the Municipal Association of Victoria as the representative bodies of local government in New South Wales and Victoria. There was a similarity of views in relation to: (1) inputs of an AC; (2) the behavioural nuances of the rigour of debate, trust and effective communications; and (3) the relationships with councillors and management. Limitations to effectiveness included: (1) attraction and retention of members; (2) the variability of expertise and the skills of the members; (3) continuing professional development for members; (4) ‘gaming’ behaviours; (5) power games associated with the appointment process; and (6) domination of the AC by members or management. The suggested way forward is the reinforcement of a strong governance culture in local government and an effective AC providing oversight of compliance, governance, internal control and risk processes. 相似文献

Spatial Statistics and Real Estate 总被引:11,自引:2,他引:9

Real estate has historically employed statistical tools designed for independent observations while simultaneously noting the violation of these assumptions in the form of clustering of same sign residuals by neighborhood, along roads, and near facilities such as airports. Spatial statistics takes these dependencies into account to provide more realistic inference (OLS has biased standard errors), better prediction, and more efficient parameter estimation. This article provides an overview of the field and directs readers to the relevant literature and software. 相似文献

We investigate the relation between founding‐family ownership and firm performance. We find that family ownership is both prevalent and substantial; families are present in one‐third of the S&P 500 and account for 18 percent of outstanding equity. Contrary to our conjecture, we find family firms perform better than nonfamily firms. Additional analysis reveals that the relation between family holdings and firm performance is nonlinear and that when family members serve as CEO, performance is better than with outside CEOs. Overall, our results are inconsistent with the hypothesis that minority shareholders are adversely affected by family ownership, suggesting that family ownership is an effective organizational structure. 相似文献

从1994年到2005年7月21日,中国把其汇率固定在1美元兑换8.28元人民币的水平。此后的人民币汇率机制改革使得人民币汇率在严格控制下开始小幅升值。由于中国的劳动生产率增长相当迅速,贸易盈余持续增长,并积累了大量美元外汇储备。这引发了美国的“排华风潮”,并强烈要求人民币进一步升值。尽管人民币升值并不能降低中国的贸易盈余,但人民币升值的威胁将降低中国的名义利率——1978—1995年的“排日风潮”和日元升值就是如此。日元过度升值引起的通货紧缩,加之零利率的流动性陷阱,造成了20世纪90年代成为日本的“失去的十年”,在新千年里,这同样可能在中国重演。 相似文献
