家族企业家双重性特征与家族企业融资决策——来自中小家族上市公司的经验证据

以高阶理论为依据,从管理者的角度研究家族企业家双重性特征与家族企业融资决策的关系。基于2004~2007年在深圳中小企业板上市的家族企业样本的实证研究发现,家族企业家的性别、任职年限、政治身份、企业家的风险倾向、控制权偏好与家族企业融资决策之间存在显著的相关性;实证研究没有发现企业家年龄与融资决策的相关性。本研究对高阶理论在我国中小家族企业中的应用是一个有益的补充,该研究的启示意义在于,研究家族企业的融资决策时,必须考虑到企业家的相关特征。同时,本文对于更好地理解家族企业的融资行为,优化家族企业的融资结构具有重要的指导作用。     

Variance bounds on the permanent and transitory components of stochastic discount factors

In this paper, we develop lower bounds on the variance of the permanent component and the transitory component, and on the variance of the ratio of the permanent to the transitory components of SDFs. Exactly solved eigenfunction problems are then used to study the empirical attributes of asset pricing models that incorporate long-run risk, external habit persistence, and rare disasters. Specific quantitative implications are developed for the variance of the permanent and the transitory components, the return behavior of the long-term bond, and the comovement between the transitory and the permanent components of SDFs.

Top management: the missing stakeholder in the HRM literature

Abstract

Despite the significant influence that top management exerts on different aspects of people management, it remains the missing stakeholder in the HRM literature. In this paper, we take stock of previous research, and conclude that it is scarce and lacks consolidation. On the basis of our findings, but also thinking in terms of what is still missing, we develop a conceptual framework that may guide further research, advocating for the need to consider co-evolutionary approaches in an attempt to integrate selection and adaptation perspectives, as well as multi-level and multi-actor factors. Future work should systematically address and distinguish top management characteristics from top management agency and link these more clearly to a diversity of HRM dimensions. By doing so, scholars will help to firmly incorporate the role of top management in the research agenda of HRM and pursue different avenues that can be scientifically sound as well as practically relevant.     

Functional Itô calculus†

We extend some results of the Itô calculus to functionals of the current path of a process to reflect the fact that often the impact of randomness is cumulative and depends on the history of the process, not merely on its current value. We express the differential of the functional in terms of adequately defined partial derivatives to obtain an Itô formula. We develop an extension of the Feynman-Kac formula to the functional case and an explicit expression of the integrand in the Martingale Representation Theorem. We establish that under certain conditions, even path dependent options prices satisfy a partial differential equation in a local sense. We exploit this fact to find an expression of the price difference between two models and compute variational derivatives with respect to the volatility surface.     

CEO hometown identity and firm green innovation

Drawn on the upper echelons theory, this study investigates how chief executive officer (CEO) hometown identity drives firm green innovation. We propose that CEO hometown identity has a positive impact on a firm's green innovation performance. Furthermore, we explore the moderating role of managerial discretion determined by organizational and environmental factors (i.e., institutional ownership and market complexity). We propose that institutional ownership negatively moderates the positive relationship between CEO hometown identity and green innovation, but market complexity plays a positive moderating role. Using Chinese publicly listed firms from 2002 to 2016 in heavily polluting industries, our findings support these hypotheses. Our research contributes to the upper echelons theory and corporate social responsibility literature and has substantial practical implications.

Upper‐echelon executive human capital and compensation: Generalist vs specialist skills

This study extends current knowledge of upper echelon executive compensation beyond the CEO, specifically CFO compensation, based on whether they possess generalist or specialist skills. We find that “strategic” CFOs with an elite MBA (generalist) consistently command a compensation premium, while “accounting” CFOs (specialist) and CFOs with a non‐MBA master's degree, even from an elite institution, do not. Further, scarce “strategic” CFOs are awarded both higher salaries and higher equity‐based compensation. Our findings support the view that unique complementarities between scarce CFOs and firms increase these executives' bargaining power leading to pay premium. Our results are robust to post‐hiring years, firm sizes, board characteristics, and CFO's insider/outsider status. We contribute at the confluence of upper‐echelon compensation, executive human capital, resource‐based view, and assortative matching literatures. Copyright © 2014 John Wiley & Sons, Ltd.

Using meta‐analytic structural equation modeling to advance strategic management research: Guidelines and an empirical illustration via the strategic leadership‐performance relationship

This paper demonstrates how meta‐analysis can be combined with structural equation modeling (MASEM) to address new questions in strategic management research. We review this integration, describe its implementation, and compare findings from bivariate meta‐analyses, a direct‐effect structural equations model, and two mediating frameworks using data on the strategic leadership and performance relationship. Results drawn from 208 articles that collectively included data on 495,638 observations demonstrate the new insights available from MASEM while also suggesting a revision to conventional thinking on strategic leadership. Whereas some theories posit that boards of directors influence firm performance through monitoring and disciplining the top management team, MASEM provides more support for the view that boards mediate the top management teams' decisions. Implications for applying MASEM in strategic management are offered. Copyright © 2014 John Wiley & Sons, Ltd.
