Heterogeneous beliefs with herding behaviors and asset pricing in two goods world

We construct a incomplete information equilibrium model with heterogeneous beliefs and herding behaviors to identify their joint effects on the dynamics of asset prices. Herding behaviors make investors revise some of their estimations about expected growth rates of goods streams toward to the other one’s by a manner of weighted average of their own forecast and the other’s. As we expected, herding behaviors generate influences on the Radon Nikodym derivative, that is so-called “sentiment” as in Dumas et al. (2009), and in turn not only impact the dynamics of asset prices but also generate influences on investors’ survivals. We also show that introducing heterogeneous beliefs with herding behaviors permits to explain both the Backus–Smith puzzle and the mixed results about the influences of herding behaviors on asset prices. Moreover, we uncover that herding behaviors have positive influences on stocks’ risk premiums.     

Cultural distance and cross-border bank linkages

This study investigates the effect of cultural distance on global bank linkages using country-pair data for the period 1990–2013. We followed Schwartz (2006) to measure cultural distance, and employed the number of bank pairs involved in cross-border syndicated lending from the source to target countries as a measure of bank linkages. We found that cultural distance has a negative association with bank linkages. This effect is stronger in countries featuring higher informational asymmetries, as represented by weaker institutions, higher uncertainty, or revolution shocks. Our results hold even when employing alternative measures of bank linkages and cultural distance, and when considering the potential endogeneity of cultural distance.     

Policy competition,imitation and coordination under uncertainty

The paper analyzes under what circumstances policymakers experiment with policies with uncertain outcomes, when they prefer to imitate policies initiated in other countries, and when they prefer to coordinate policies internationally. Policymakers have private costs of active policies and compete internationally in a yardstick competition which gives rise to a potential distortion between what citizens want and what policymakers do. I find that policymakers’ policies as well as regime choice deviate from what citizens want but that an increase in uncertainty about policy outcomes decreases this distortion.     

Which stock price component drives the Amihud illiquidity premium?

We examine the components of stock prices that play a key role in the pricing of the Amihud (2002) illiquidity measure. We first decompose the stock price series into permanent and transitory components and then construct the half-Amihud illiquidity measures on the days of positive and negative permanent price returns. We find that the transitory half-Amihud measure on the days of negative permanent price returns plays an important role in pricing the Amihud illiquidity even after controlling for the turnover ratio. This finding contrasts with that of Lou and Shu (2017) in that both the trading volume component and transitory price impact, drive the Amihud illiquidity premium.     

经济政策不确定性与家族企业创新 ——融资约束及政府补助视角

家族企业作为社会发展的主要参与者,在促进经济增长方面发挥着不可替代的作用。家族企业若想实现长期发展,必然依靠创新。然而,我国家族企业普遍面临创新投入不足、创新产出效率低下等问题。基于2010—2018年中国上市家族企业数据,分析经济政策不确定性对于家族企业创新是否存在激励作用。结果发现,经济政策不确定性提高,会对家族企业创新研发活动投入与产出产生正向激励作用,促进家族企业创新。从融资约束与政府补助视角,分析两者在上述正向激励作用中的调节作用。结果表明,对于融资约束小以及受到政府补助的家族企业而言,其受到经济政策不确定性的正向激励作用更显著,有助于其开展创新研发活动。结论不仅验证了经济政策不确定性对于家族企业创新的激励作用,还揭示了融资约束以及政府补助的调节作用,可为政府制定相应补助政策,构建完善的金融市场提供理论支持和经验证据。     

产学研融合程度对科技型中小企业创新绩效的影响

构建产学研深度融合的技术创新体系,是我国为应对当前复杂多变的国际环境、满足新时代高质量发展要求的重要战略。基于产学研融合内涵,构建微观层面企业产学研融合程度综合评价模型,实证检验产学研融合程度对科技型中小企业创新绩效的影响以及环境不确定性的调节作用。结果表明,我国科技型中小企业产学研融合广度、深度和频度总体均呈波动上升趋势,正逐步迈向深度融合阶段;产学研融合广度和深度对科技型中小企业创新绩效具有正向影响,产学研融合频度对科技型中小企业创新绩效具有负向影响;环境不确定性会增强产学研融合广度对科技型中小企业创新绩效的正向影响,削弱产学研融合深度对科技型中小企业创新绩效的正向影响,增强产学研融合频度对科技型中小企业创新绩效的负向影响。结论可拓展产学研合作相关研究,发展产学研融合理论,为解决我国科技型中小企业产学研融合效率偏低、机制不佳等问题提供实践指导。     

关系嵌入、知识获取与BOP市场导向的产品创新：内外部不确定性的调节作用

在主流市场日趋饱和的背景下,更多企业将目光聚焦于金字塔底层市场。基于权变视角,探索企业在BOP跨部门合作网络中,双边关系耦合与网络嵌入交互构建的双环协同机制如何影响企业外部知识攫取,进而作用于BOP市场导向的产品创新。采用大样本问卷调查,收集396家电动自行车企业数据,利用多元回归分析对研究假设进行实证检验。研究表明,跨层级嵌入双环协同机制与知识获取呈倒U型关系,高外部不确定性会增强该倒U型关系,但高内部不确定性对该倒U型关系无显著影响;通过知识获取的部分中介传导效应,最终跨层级嵌入双环协同与BOP产品创新呈倒U型关系。结论对企业把控BOP网络嵌入程度、优化网络配置及网络治理具有一定指导意义。     

Historical resources, uncertainty and preservation values: An application of option and optimal stopping models

State agencies and private historical organizations frequently acquire historical sites with unknown characteristics. In this paper, we provide two approaches to evaluating the preservation decision. In the first approach, we show that a historical site which is not permanently preserved provides citizens with a certain flexibility whose value can be measured as an option on the maximum between the current real estate value and the preservation value. In the second approach, we assume that the organization has an infinite planning horizon and chooses the optimal sale date. Using a contingent valuation estimate of the public's willingness to pay for preservation of a specific historical site and the real estate price, we provide simulation values of the preservation option value and the optimal stopping rule.     

环境不确定下企业孵化网络治理机制对治理绩效影响研究

从企业孵化网络本身以及环境视角分析了企业孵化网络治理绩效的影响因素,通过企业孵化网络治理机制对治理绩效关系的实证分析,验证了环境不确定下企业孵化网络的契约治理机制、管理治理机制对治理绩效的影响。结果表明:企业孵化网络治理机制中的契约治理机制、关系治理机制对治理绩效具有正向调节作用;环境不确定性会扩大或缩小治理机制对治理绩效的作用强度。企业孵化网络在高市场不确定性环境下,采用关系治理机制的绩效较好;在高技术不确定性环境下,采用契约治理机制的绩效较好。
