An N-dimensional generalization of the Amiti–Weinstein estimator

Amiti and Weinstein proposed an estimation framework to disentangle credit demand and supply shocks using matched bank-firm loan data. Here, we show that their estimator can be generalized to capture shocks arising in an arbitrary number of dimensions. Our algorithm permits empirical researchers to analyse multi-dimensional data sets using the Amiti–Weinstein framework. This may be beneficial both for studies on micro-level outcomes as well as for the literature on assessing the macroeconomic impact of idiosyncratic shocks. In an empirical application to a firm-product-country export data set, we highlight the usefulness of the generalized Amiti–Weinstein estimator, and we demonstrate the importance of considering additional dimensions when gauging the effect of granular shocks on aggregate fluctuations.     

The role of stock ownership by US members of Congress on the market for political favors

I examine whether stock ownership by politicians helps to enforce noncontractible quid pro quo relations with firms. The ownership by US Congress members in firms contributing to their election campaigns is higher than in noncontributors. This bias toward contributors depends on the financial incentives of politicians and the relation's value. Firms with a stronger ownership–contribution association receive more government contracts. The financial gains from these contracts are economically large. When politicians divest stocks, firms discontinue contributions to the politicians, lose future contracts, and perform poorly. Politicians divest the stocks in contributors, but not in noncontributors, in anticipation of retirement.     

国有企业工作经历、企业家才能与企业成长

人力资本的高效配置和企业家才能的充分发挥关系到经济的可持续发展,制度建设如果能促进资源合理流向具有企业家才能的企业家,就能创造更多就业和社会财富。基于全国1997—2016年的私营企业调查数据,本文考察企业家的国有企业工作经历对企业成长的影响。研究结果显示,企业家的国有企业工作经历使得企业在市场扩张和盈利能力等方面表现更好,带来了更高水平的企业成长。机制讨论表明,企业家行为带有明显的烙印效应,国有企业工作经历为企业家带来了更多的社会资本和更高的公司治理水平,从而促进了企业成长。为了缓解由于选择性偏误等带来的内生性,本文采用倾向得分匹配、处理效应模型、代理变量、双差分模型等方法进行处理,结论仍然稳健。中国经济要向资源配置效率改善型模式转变,企业家才能的发挥至关重要,国有企业改革不仅应注重产权等方面的改革,同时也要充分重视国有企业改革带来的人力资本溢出效应。在不断深化国有企业改革的大背景下,本文从企业家才能培育和人力资本配置效应的角度考察国有企业改革问题,倡导国有企业改革进程中进一步营造企业家才能发挥的空间和制度安排,提高人力资本配置效应,从而促进中国经济健康可持续发展。     

Exploring alternative strategic management paradigms in high-growth ethnic and non-ethnic family firms

The primary research question examined in this paper is whether ethnic and non-ethnic family firms in the United Kingdom differ in their strategy-making. The paper uses the typology of strategic decision-making produced by Whittington [(1993). What is strategy: and does it matter? New York: Routledge] to derive contrasting predictions of strategy-making by ethnic versus non-ethnic firms. Drawing on a questionnaire study of 76 high-growth family firms, and subsequent in-depth fieldwork with 40 of these, the findings show that the ethnic origin of the controlling family has a significant influence in determining the dominance of a particular strategy paradigm. However, successful high-growth family firms are not associated with any particular school of strategy. The influence of family bonding on strategy-making was greater in ethnic family firms than non-ethnic family firms. The advent of the second generation of South Asians in family firms, and closer integration of immigrant and host communities, has not altered these apparent differences. The findings challenge researchers on family firms to adopt a multiple perspective approach to strategy-making.

Boards of directors in family firms: a generational perspective

The purpose of this study is to advance the understanding of boards of directors in family firms. Building on generational changes in family attributes, we argue that firms in a different generational phase have different governance needs and characteristics. With regard to board task needs, the empirical results indicate a convex generational evolution in the need for board advice, and a rise over the generations in the need for board control. With regard to board composition, we find that the likelihood of having an outside director on the board has a convex generational trend. This relationship seems to be fully mediated by the firm’s board task needs. Furthermore, the number of family directors seems to increase over the generations. This study demonstrates that it is important to consider the generational phase of the family firm in order to understand its governance system.

我国高科技上市公司债务结构治理效应的实证研究

以2003年度中国证券市场上的高科技上市公司为样本,考察了我国上市公司的债务结构的治理效应。研究发现,公司绩效指标与资产负债率、流动负债比率、长期负债率表现出了显著的负相关关系,此说明债务结构的治理效应对公司绩效产生了显著的负面影响,即债权治理在中国高科技上市公司中表现出软约束和治理弱化的特征,没有发挥出应有的作用。     

The Relationship of Leadership Style and CEO Values to Ethical Practices in Organizations

This study analyzes the relationship between CEO values, leadership style and ethical practices in organizations. The ethical practices of formal statement of ethics and diversity training are included in the study, as well as four categories of values based on Rokeach's (1973) typology including personal, social, competency-based and morality-based. Results indicate that all four types of values are positively and significantly related to transformational leadership, with transactional leadership positively related to morality-based and personal values, and laissez-faire leadership negatively related to competency-based values. When size of company and values are controlled, transformational leadership explains a significant amount of change in formal statement of ethics, and transactional leadership explains a significant amount of change in diversity training.     

银企关系与房地产公司的信贷违约--基于嵌入性视角的研究

嵌入性理论认为,社会资本是企业可以利用的重要资源。本文基于我国房地产上市公司信贷数据,发现银企关系作为企业一项重要的社会资本提供了财务变量和股票市场变量以外有关公司违约的重要信息,有助于提高违约风险模型的预测能力。其中银企双边关系久期、主营房地产业务时间以及公司国有背景与违约风险率显著负相关,银企关系规模的实际作用效果与关系网络的规模和结构有关。
