欧债危机的根源及对策分析——基于最优货币区内生性理论

根据最优货币区内生性理论,加入最优货币区的决定取决于一体化、对称性和劳动力市场弹性三种内生性。美国次贷危机导致欧元区对称性下降,金融一体化、劳动力市场弹性不足和财政转移支付等补偿机制的缺失,使得欧元区未能形成最优货币区。欧元区必须通过要素市场改革和推进财政一体化等措施,才能走出困境。     

Mankind at the Starting Point

The most striking feature of the current economic situation in Spain is the huge unemployment rate, above 25 percent. From an orthodox perspective, we suggest that this unemployment is the result of a highly inflexible labor market, which needs to be reformed by introducing flexibility measures. The paper argues, however, that labor market reforms introduced since the early 1980s, allowing an excessive use of temporary employment contracts, have had perverse effects on the Spanish economy. They have affected negatively not only aggregate demand and supply, but also income distribution. The emergence of these market reforms helps explain the current rate of unemployment as well as the deep impact of the global financial crisis on overall Spanish economic activity.     

现阶段我国经济增长的源泉分析

从总体上讲,我国近些年来的经济增长应是制度转轨、对外开放与二元经济转型等因素相互作用与协同发展的结果;在我国的经济增长过程中,制度一经济增长论与二元经济发展论可以同时成立;不过。从各因素对经济增长的总量贡献上看,二元经济转型的贡献要远大于其他因素。这说明了我国的经济增长不仅享受了渐进式的制度变迁的好处,而且也享受到了转轨的“后发优势”。当然。从各种因素对经济增长作用的发展趋势与作用的空间性上看,制约我国未来经济增长的核心经济因素将会从以往的经济制度瓶颈转向产业结构升级与技术进步上。     

工作—家庭平衡的企业制度安排

工作已经通过网络渗入家庭,员工面临严重的工作—家庭冲突,影响组织绩效和生活质量。工作—家庭平衡作为企业家庭伦理理论的核心问题已成为制度设计的中心问题。对工作—家庭平衡制度安排的理论与实证研究发现,工作—家庭平衡还没有成为政府、企业和员工的共享信念,制度设计失去社会价值观基础;弹性工作制是有效的正式企业制度;家庭照顾福利是无效的正式企业制度;经理须持之以恒支持员工平衡工作—家庭需要、控制因享用工作—家庭平衡福利而带来的负面职业生涯后果。两者是有效的非正式制度安排。据此提出的政策建议是:政府要在全社会倡导、培育以工作—家庭平衡为核心的企业家庭伦理管理哲学、提供家庭照顾福利作为公共制度供给;企业进行系统的组织文化改造;员工培育照顾家庭的应得权利感。     

Is the relationship between investment and conditional cash flow volatility ambiguous,asymmetric or both?

We investigate the effect of cash flow volatility on investment. Our evidence suggests that financially constrained firms decrease investment (i) when experiencing persistently high volatility; (ii) when experiencing both high volatility and negative cash flow growth realisations; and (iii) when holding low cash levels and experiencing both high volatility and a negative cash flow growth realisations. In financially unconstrained firms, the above effects are either not found or are of relatively low economic importance. Overall, our findings lend support to the financial flexibility literature and tend to contradict predictions of the real options literature.

CEO career horizon,corporate governance,and real options: The role of economic short‐termism

Research Summary: Combining studies on real options theory and economic short‐termism, we propose that, depending on CEOs’ career horizons, CEOs have heterogeneous interests in strategic flexibility, and thus, have different incentives to make real options investments. We argue that compared to CEOs with longer career horizons, CEOs with shorter career horizons will be less inclined to make real options investments because they may not fully reap the rewards during their tenure. In addition, we argue that long‐term incentives and institutional ownership will mitigate the relationship between CEOs’ career horizons and real options investments. U.S. public firms as an empirical setting produced consistent evidence for our predictions. Our study is the first to theoretically explain and empirically show that a CEO's self‐seeking behavior will impact real options investments. Managerial Summary: This article helps to explain how a CEO's self seeking‐behavior may shape a firm's real option investment, which could result in different level of strategic flexibility. We argue that CEOs with short career horizons have less time to exercise their firms’ real options, which should lower the investments in the firms’ real options portfolios relative to CEOs with long career horizons. We study a sample of U.S. public firms and find strong evidence that a CEO's expected tenure in the firm is positively related to the real options investments at the firm level. We find that this agency issue can be mitigated by adopting appropriate corporate governance mechanisms such as long‐term incentives and institutional investors.     

Is a Policy of Free Movement of Workers Sustainable?

In this paper, we study the costs and benefits of the adoption of a policy of free movement of workers. For countries to agree on uncontrolled movements of workers, short‐run costs must be outweighed by the long‐term benefits of better labor‐market flexibility and income smoothing. We show that such a policy is less likely to be adopted when workers are more impatient and less risk‐averse, when production technologies display stronger decreasing returns, and when countries trade a significant share of their products.     

最低工资、就业弹性及就业效应研究

最低工资标准的提升对于就业的效应究竟是正是负,目前理论界并没有一致的论证结果。本文首先从市场结构和企业应对措施两个角度,梳理了西方学界关于最低工资对就业影响的作用机理,然后建立一个涉及农民工、企业和政府三方的博弈模型,推导出行业就业弹性对劳动参与的关键作用,并利用全国各省市六个行业的面板数据进行了实证分析。本文的主要结论是,最低工资的实施标准按行业设置比目前按地区＂一刀切＂的模式更具科学性。
