Stock price crash sensitivity refers to the conditional probability of a stock crash when the market collapses. It focuses on individual stocks' sensitivity to the market crash and can affect stock pricing significantly. Although the crash sensitivity of China's stock market is very high as a whole (Weigert, 2016), different individual stocks show varying degrees of crash sensitivity. This paper, adopting the perspective of institutional investors, explores the reasons for the difference in crash sensitivity in China's stock market, and finds that: First, institutional investors' shareholdings is positively related to firms' stock price crash sensitivity. However, after dividing institutional investors into professional (represented by financial institutions) and non-professional institutional investors (represented by general legal persons), we find that only professional institutional investors' shareholdings is negatively related to firms' stock price crash sensitivity. Second, the impact of professional institutional investors on the crash sensitivity is influenced by stock liquidity and media sentiment: when the stock liquidity of listed companies is good or the media sentiment is strong, the negative impact of professional institutional investors on the crash sensitivity is accordingly high. This paper, by highlighting the investor structure, attempts a pioneering exploration of the influencing factors of the difference in stock price crash sensitivity in China. Our empirical results enrich research on stock price crash sensitivity and the heterogeneity of institutional investors. They can also serve to guide regulatory authorities' development of institutional investors and efforts to maintain market stability. 相似文献

新冠肺炎疫情爆发之后,人们非常关注通过提振消费来防止经济出现大幅度下滑。事实上,提振消费政策同时也具有社会政策属性。调查表明,在双循环背景下,通过社会政策维持一定的生计方式,并保持人们的消费水平具有重要意义。从对企业家FR、小手工业者BF与房屋中介LC的访谈资料以及在麓村、唐村的调查情况来看,人们在理解提振消费政策时具有共同的叙事特征。叙事本身具有鲜明的政策偏好,其核心是一定空间背景下结构与利益的分配正义问题。而风险社会与低欲望社会特征的并存深刻地影响着提振消费政策的制定,是行动者要面对的情境。为此,需要从规则与制度、空间与代际等长期性和持续性的角度系统思考提振消费政策的受益对象与受益群体,防止政策偏好所带来的结构性挑战。 相似文献

We investigate the effect of portfolio diversification on banking systemic risk, where the network effect is incorporated. We analyze three kinds of interbank networks, namely, random networks, small-world networks and scale-free networks. We show that the effect of portfolio diversification on banking systemic risk depends on interbank network structures and shock types. First, systemic risk increases first and then reduces with the increase of the level of portfolio diversification in the case of the individual shock. Second, in the case of the systemic shock, systemic risk reduces with the increases of the level of portfolio diversification. Third, banking systems with scale-free network structures are the most stable, and those with small-world network structures are the most vulnerable. 相似文献

This study examines (i) how top-level managerial institutional ties drive corporate sustainability strategies of emerging market firms operating under conditions of institutional adversity; (ii) the impact of corporate sustainability strategies on market performance; and (iii) the moderating role of financial resource slack on the relationships between corporate sustainability strategies and market performance. The study builds from institutional development logic and the structure–conduct–performance paradigm. Primary data are collected from 300 firms operating in a major sub-Saharan African market. Findings show that top-level managerial institutional linkages with regulatory national governmental officials, local community leaders, and top managers at other firms drive corporate proactive and responsive sustainability strategies, which in turn influence market performance. In addition, the findings reveal that financial resource slack strengthens the path between corporate proactive sustainability strategies and market performance, but not the path between corporate responsive sustainability strategies and market performance. Theoretical and practical implications are discussed. 相似文献

Following the approach of interpolation, this paper proposes the multiple exponential decay model to fit yield curves for both the U.S. TIPS market and the conventional Treasury security market. Several estimation methods, including the unconstrained/constrained nonlinear minimization, quadratic programming, and the iterative linear least squares, are applied to estimate the unknown parameters according to different curve‐fitting purposes. Comparisons between the proposed model and the alternatives show that the multiple exponential decay successfully (1) adapts to a variety of shapes associated with yield curves, (2) (partially) keeps in line with the economic interpretations of Nelson–Siegel summarized by Diebold and Li ( 2006 ), and (3) dominates the competing models in curve‐fitting performance measured by mean fitted‐price errors over the sample period. In addition, the exact specification of a nonparametric interpolation model is pinned down by applying three statistical tools, which enable us to jointly take into account validity, optimality, and parsimoniousness of the proposed model. 相似文献

Corporate social responsibility (CSR) has attracted wider research interests over recent decades. While some studies have examined the impact of CSR activities on firm competitive advantage (CA), the findings so far remain contradictory. Moreover, the role of export orientation, firm strategy, and structure on the association between CSR and CA has not been explicitly examined. Thus, the purpose of this study is to examine the moderating role of export orientation, firm strategy, structure, and firm size on the association between CSR and CA. Using a sample of 179 responses from management staff in organizations across five sectors in a developing country context of Ghana, the study found positive effects of CSR on CA. The study contributes to the resource‐based view (RBV) scholarship by confirming the important complementary effect of export orientation and organizational structure as important resources and capabilities on the CSR–competitiveness relationship. However, no evidence of a moderating effect of firm strategy, or firm size on the CSR–CA relationship was found. These findings are instructive, impactful, and enrich the existing literature on CSR and strategy. Implications for theory and practice are also discussed. 相似文献

研究目的:分析家庭结构对农民流转土地意愿的影响,并揭示其内部机理的形成,以期为土地流转政策的完善提供参考。研究方法:因子分析法和结构方程模型。研究结果:(1)家庭人口特征、土地使用特征、户主个体特征及家庭决策特征4类外源潜变量会显著影响农地流转意愿;(2)可观测变量对外源潜变量的解释能力较强,其中,家庭总人口、实际经营及流转土地面积、户主年龄、家庭内部矛盾解决方式分别对这4类外源潜变量的解释能力相对较好,即家庭总人口越多、实际经营及流转土地面积越小、户主年龄越大、依赖于内部解决矛盾的家庭更愿意流转农地。研究结论:家庭结构主要通过主动依赖、扶养压力、收入偏好、农地保障、决策信息5种机理对流转意愿产生影响,未来土地流转政策的完善应重视解决这些问题。 相似文献
