环境质量变化对游客福利的影响——基于旅行费用和条件行为联合数据

环境质量是影响游客旅游需求及福利的重要因素,但单一使用陈述性偏好法或揭示性偏好法仍存在诸多局限性。为探究环境质量改变对游客需求及福利变化的具体影响,结合旅行费用与条件行为数据,在明确现有环境质量状况下景区价值基础上,评估环境质量改善与恶化两种情景下,游客消费者剩余的变化。结果表明,环境质量改变直接影响旅行次数,从而增加或减少消费者剩余,但不会通过影响游客旅行费用间接改变消费者剩余,实际行为与条件行为数据偏好存在一致性;白洋淀景区当前消费者剩余为909.09元/次;环境质量改善使游客平均旅行次数增加1.45次/年,并使每位游客每年的消费者剩余增加1 318.18元;环境质量恶化使游客平均旅行次数降低1.41次/年,并使每位游客每年的消费者剩余减少1 281.81元。     

Empirical Evidence on Corporate Risk‐Shifting

We study empirically whether nonfinancial firms’ behavior is consistent with systematic risk‐shifting. We compare firms’ operating risk before and after a debt issue, under the assumption that if there is any risk‐shifting it is most likely to occur right after a debt issue. We document a significant increase in firms’ operating risk, even after adjusting for industry influences. The risk‐shifting is higher for firms with no subsequent debt issues, and for firms with lower credit ratings. Other determinants are earnings volatility, size of debt issue, and whether the bond is callable.     

Relative Liquidity,Fund Flows and Short‐Term Demand: Evidence from Exchange‐Traded Funds

We show that highly liquid Exchange‐Traded Funds (ETFs), especially those that are more liquid than their underlying basket of securities (i.e., positive relative liquidity), are particularly attractive to investors. Using three definitions of liquidity, we find that relative liquidity predicts net fund flows, as well as inflows and outflows positively and significantly. We further document a liquidity clientele among institutional investors: (i) relative liquidity is significantly more important for short‐ than for long‐term investors; and (ii) relative liquidity is inversely related to investors’ average holding duration in the ETFs. These two findings provide evidence that relative liquidity encourages short‐term demand.     

我国市场化改革对经济增长贡献的实证分析

市场化改革与经济增长是目前我国经济研究的一个热点问题。本文通过梳理我国经济增长方面相关的研究文献,指出了现有研究中在估计方法与数据方面的不足,提出了一个可行的改进方法。并根据扩展的新古典经济增长模型,利用我国30个省市区的面板数据,采取直接估计的方法,在全要素生产率中把技术进步与市场化改革加以分离,分别测度了技术进步与市场化改革对经济增长的贡献。我们发现我国的市场化改革对经济增长有着显著的正影响,贡献率达到14.22%。这对我国进一步推进市场化改革,促进经济增长,不断完善社会主义市场经济体制提供了理论上与实证上的支持。     

The influence of relative values of outside director stock options on firm strategic risk from a multiagent perspective

Prior work has examined the effects of absolute levels of outside director stock option grants on risk behavior without recognizing that relative stock option values could differentially affect risk taking. Drawing from the house money effect perspective, we extend this literature by examining how positive deviation from prior outside director option grants values influences firm strategic risk. Additionally we draw from the behavioral agency model and the power literature to develop a multiagent contingency framework suggesting the effect of positive director pay deviation depends on the incentives and power of CEOs reflected in CEO stock ownership and CEO duality, respectively. Our empirical results indicate positive pay deviation has a positive effect on firm risk taking while high ownership and duality independently and jointly weaken this base relationship.

Free‐riding in multi‐party alliances: The role of perceived alliance effectiveness and peers' collaboration in a research consortium

Research summary : Multi‐party alliances rely on partners' willingness to commit and pool their efforts in joint endeavors. However, partners face the dilemma of how much to commit to the alliance. We shed light on this issue by analyzing the relationship between partners' free‐riding—defined as their effort‐withholding—and their perceptions of alliance effectiveness and peers' collaboration. Specifically, we posit a U‐shaped relationship between partners' subjective evaluations of alliance effectiveness and their free‐riding. We also hypothesize a negative relation between partners' perceptions of the collaboration of peer organizations and their free‐riding. Results from a mixed‐method study—combining regression analysis of primary data on a major inter‐organizational research consortium and evidence from two experimental designs—support our hypotheses, bearing implications for the multi‐party alliances literature. Managerial summary : Free‐riding is a major concern in multi‐party alliances such as large research consortia, since the performance of these governance forms hinges on the joint contribution of multiple partners that often operate according to different logics (e.g., universities, firms, and government agencies). We show that, in such alliances, partners' perceptions have relevant implications for their willingness to contribute to the consortium's shared goals. Specifically, we find that partners free‐ride more—that is, contribute less—when they perceive the effectiveness of the overall alliance to be either very low or very high. Partners also gauge their commitment to the alliance on the perception of the effort of their peers—that is, other organizations similar to them. These findings provide managers of multi‐party alliances with additional levers to motivate partners to contribute fairly to such joint endeavor. Copyright © 2015 John Wiley & Sons, Ltd.     

Performance deviations and acquisition premiums: The impact of CEO celebrity on managerial risk‐taking

Research summary: This article draws on identity control theory and a study of acquisition premiums to explore how CEO celebrity status and financial performance relative to aspirations affect firm risk behavior. The study finds that celebrity CEOs tend to pay smaller premiums for target firms, but these tendencies change when prior firm performance deviates from the industry average returns, thereby leading these CEOs to pay higher premiums. The study also finds that the premiums tend to be even larger when celebrity CEOs have more recently attained celebrity status. Taken together, these findings contribute to identity control theory and CEO celebrity literatures by suggesting that celebrity status is a double‐edged sword and that the internalization of celebrity status by CEOs strongly influences the decision‐making of CEOs. Managerial summary: The purpose of this article is to examine how CEO celebrity status and financial performance relative to aspirations affect the size of acquisition premiums. The study finds that celebrity CEOs tend to pay smaller premiums for target firms. However, when celebrity CEOs' prior firm performance is either better or worse than the industry average, these CEOs pay higher premiums. This situation is exacerbated when the CEO has only recently been crowned a celebrity. In effect, these CEOs feel great pressure to match the inflated performance expectations that come with celebrity status. These findings suggest that being a celebrity is a double‐edged sword. The implication here is that CEOs who have recently been crowned a celebrity should be aware of these pressures and cope accordingly. Copyright © 2015 John Wiley & Sons, Ltd.

Risk‐Coping Measures against Health Shocks during the Process of Penetration of Health Insurance in Vietnam

Does the recent introduction of public health insurance influence households' risk‐coping measures in developing countries? This study investigates risk‐coping measures for health shocks using a Living Standard Measurement Survey in Vietnam where universal health coverage is aimed to be achieved. The estimated results suggest that precautionary savings are the main form of assets in poor households. Health insurance seems to be used by people in poor health, which indicates that the problem of adverse selection exits. Importantly, get well gifts in the form of money play a significant role in helping households cope with health shocks. A traditional informal insurance system still exists in close Vietnamese communities.
