中国企业人力资本产权变革三次浪潮评析

人力资本股权化是现代企业产权制度变革的基本逻辑和大趋势.如何在实际操作层面解决"两权分离"悖论,不仅是现代公司制度运作和发展的主题,也是中国企业人力资本产权制度变革的逻辑起点、核心问题和主要矛盾.1992年以来,中国企业人力资本产权变革经历了三次浪潮.目前,对于中国企业来说,实现人力资本股权化、稚行股权激励计划,已经不是什么"理论"问题而是如何实际"行动"的问题.基于人力资本产权制度变革积极推行股权激励计划,是未来中国企业必然而明智的战略选择.     

中国城镇养老保险制度改革的收入分配效应

在公共养老保险制度下,可以通过调整养老保险的缴费率或养老金计发办法来影响参保人一生中的养老金纯受益,从而实现代际间和代际内的收入再分配。本文利用中国国家统计局2002年的城市住户调查数据,分别估计城镇参保职工在1997年养老保险制度和2005年最新养老保险制度下的终生养老金纯受益,并以此从代际间和代际内的角度对中国养老保险制度改革的收入分配效应进行定量分析。分析表明:在1997年的改革方案下改革前的养老保险制度中存在的逆向收入转移效果得到改善;但在2005年改革方案下,2002年时40岁以上的群体中存在较明显的逆向收入转移倾向。另一方面,从代际分配来看,1997年改革方案的代际不平衡大于2005年改革方案;在2005年改革方案下各代人的养老金纯受益都有所提高,但这是以养老保险制度的缴费率和养老金计发办法不变,养老财政收支能维持平衡以及参保人在整个工作期间按规定缴费为前提的。

Waves and Determinants in Mergers and Acquisitions: The Case of Latin America

This article contributes to the current literature on mergers and acquisitions (M&As) by identifying the existence of waves and the determinants of M&A activity in the economies of Argentina, Brazil, Chile, Colombia, Mexico, and Peru. From a sample of 2,391 M&A announcements reported by Thomson One on these countries, applying the methodology proposed by Harford (2005), evidence of M&A waves is found for the periods 1995–2002 and 2003–2010, as reported for other regions in various international studies. After controlling for economic and business environment variables, as well as for profitability and book-to-market variables at the industry level, we find evidence that supports neoclassical theory as a main explanation for M&A activity but not for the misvaluation effect.     

Social capital and innovation in family firms: The moderating roles of family control and generational involvement

Drawing on the social capital literature, we examine whether the co-existence of distinct yet interacting social groups, namely family and non-family members, creates the conditions for increased family firm innovation. In particular, we theorize that family and non-family social capital have a joint positive effect on family firm innovation and this joint effect is stronger than the single effects of family and non-family social capital. In addition, we predict that while family control has a positive moderating effect, generational involvement has a negative moderating effect on the above-mentioned relationship. With supportive empirical results, our research makes important contributions to the existing literature.

On predictive distributions of public net liabilities

The analysis of the sustainability of public sector finances requires an accounting of all future revenues and all future spending that we would expect, under current tax laws and current entitlements. The classical calculation does not acknowledge the inherent uncertainty of the future economic and demographic developments, so the results can be misleading. Our aim is to produce a more robust summary of the sustainability of the public sector than the one currently available. By taking a forecasting point of view, our formulation takes into account the uncertainty of future productivity, stock and bond markets, and demography. Methodological complications that arise in the stochastic setting are discussed. Estimates of the relative roles of economics and demographics in the uncertainty of public net liabilities are presented.     

What causes K-waves?

This commentary on the Devezas-Corredine paper raises three questions: how do we think and how do we need to think about K-waves, what causes K-waves in the Devezas-Corredine model, and in what sense do social and biological factors add to a better understanding of large-scale structural changes in the world economy.     

STRATEGIC VERTICAL INTEGRATION WITHOUT FORECLOSURE*

We determine the endogenous degree of vertical integration in a model of successive oligopoly that captures both efficiency gains and strategic effects. Foreclosure effects are purposely left aside. The profitability of integration originates in the greater ability of integrated firms to adopt a specific type of technologies. We show that vertical merger waves can stop by themselves before integration is complete because of strategic substitutability in vertical integration. This is in contrast to the strategic complementarity result in McLaren [2000] that leads to either complete integration or complete separation.     

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.
