This paper provides new insights into the relation between institutional investment horizon and stock price synchronicity and investigates whether this relationship depends on the intensity of product market competition and analyst coverage. Based on a sample of French listed companies, we find that long-term (short-term) institutional investors are associated with lower (higher) stock price synchronicity. The results also show that the negative effect of long-term institutional investors is more accentuated for firms in less competitive markets and with high analyst coverage. An additional analysis shows that the synchronicity reduction effect does not vary during the financial crisis. Overall, these findings suggest that unlike their short-term counterparts, long term investors reduce asymmetric information and help disseminate firm-specific information into stock prices.  相似文献

中国银保监会出台联合授信管理制度旨在抑制企业过度融资行为,提高资金使用效率。为检验该制度是否达到预期效果,采用2014—2018年沪深A股上市公司样本,运用非平衡面板数据回归实证考察联合授信机制对企业非效率投资的影响,发现联合授信对企业的非效率投资(包含投资不足和投资过度)呈现显著抑制效应,其中联合授信对投资过度的抑制效应最大。进一步研究发现,相较于国有、大规模、低负债、高盈利等异质属性的企业,联合授信对非国有、小规模、高负债、低盈利等属性企业的非效率投资(尤其是投资过度)抑制效应更为显著。  相似文献

E-commerce live streaming can considerably help brands improve sales dynamics, but it is multiple dilemmas in choosing suitable e-commerce live streaming product showcasing modes. To address the multiple dilemmas, we first employ the Stackelberg game to depict three e-commerce live streaming product showcasing modes: brand self-live streaming, influencer-led live streaming mixture, and influencer-led special live streaming. Second, we analyze the relationship between choices and game parameters, including live streaming stimulus sensitivity, unit service quality improvement cost, and service sensitivity. Meanwhile, through the comparative analysis of the three modes, we get the optimal threshold of each mode. Last, we conduct a case study comparing Chinese apparel and accessories brands Hodo and RUANS to verify the above relations. The results suggest that: (i) the more sensitive consumers are to live streaming stimulus, the more beneficial it is for the brand manufacturer to employ special live streaming, while the increase in unit service quality improvement cost will harm the brand manufacturer; (ii) the fixed participation fee determines the choice of e-commerce live streaming product showcasing modes; (iii) e-commerce live streaming product showcasing modes can help brands to optimize their decision-making.  相似文献

We identify farms’ optimal investment path in capital assets and compare it with their actual investment to assess the direction and extent of deviation from the optimal investment. A probit model is further used to investigate the determinants of the probability that a farmer over‐ or under‐invests in capital assets. We use a panel dataset of Dutch dairy farms over the period 2003–2013, and find that most farms under‐invest in capital assets during the study period. Although the number of farms that had over‐invested in capital assets is relatively small, these farms account for the biggest share of total investment in capital assets. The probit results show that liquidity, agricultural support payments, age, land tenure and standard output size are important variables explaining the likelihood of over‐and under‐investment.  相似文献

基于2011-2017年30个省、市、自治区的面板数据,用线性回归分析法实证分析了政府对企业的研发投入对企业R&D投入的影响。并量化了工业化水平这一变量,论证了工业化水平在这一过程中的作用。研究表明,政府对企业的研发投入能促进企业自身的R&D投入,工业化水平对政府的企业研发投入和企业R&D投入之间的作用关系具有正向的调节作用。  相似文献

The purpose of this paper is to explain differences in the productivity of investment across 84 rich and poor countries over the period 1980–2011, and to test the orthodox neoclassical assumption of diminishing returns to capital. The productivity of investment is measured as the ratio of the long-run growth of GDP to a country’s gross investment ratio. Twenty potential determinants are considered using a general-to-specific model selection algorithm. Education, government consumption, geography, export growth, openness, political rights and macroeconomic instability are the most important variables. The data also suggest constant returns to capital, so investment and the determinants of productivity of investment differences matter for long-run growth.  相似文献

企业、企业家等微观主体对货币政策的反应,在较大程度上影响货币政策的效果。货币政策可通过对企业家信心的影响,进而对公司投资效率产生作用。基于中国2007—2016年40个季度A股上市公司样本的实证研究表明:企业家信心在货币政策传导过程中有不可忽视的作用。企业家信心增强或者货币政策宽松时会加剧过度投资,减轻投资不足;企业家信心减弱或者货币政策紧缩时可以有效抑制过度投资,但会加剧投资不足。其中,国有企业对企业家信心和货币政策松紧的敏感性更强。进一步,货币政策对企业投资效率的影响,也会通过货币政策和企业家信心的交互作用而发挥作用。这种作用在国有企业和非国有企业之间无显著差异。  相似文献

以A股地方国有上市公司为研究对象,从投资效率的角度考察国有资本经营预算制度的实施效果,并进一步检验其对企业价值的影响。研究发现,国有资本经营预算能够显著抑制地方国有企业的非效率投资,尤其是抑制过度投资行为,并且这种影响对处于市场化程度较低地区的地方国有企业更加显著。进一步研究发现,国有资本经营预算能够通过抑制非效率投资来促进地方国有企业价值的提升。  相似文献

Scholars in economics and political science argue that one major function of government is to overcome coordination failure in economic development, especially during times of rapid environmental changes. But, how and through what means does the state coordinate firms to follow the changing directions of its economic objectives? This paper focuses on the case of a government-controlled business association, namely the All-China Federation of Industry and Commerce (ACFIC), and shows that the ACFIC may be serving, at least partially, as a means of avoiding the kind of coordination failures that are often associated with policy reform programs in authoritarian regimes like China when the government deems it necessary to radically and suddenly change its policy objectives. It does so by comparing the activities of firms that are members of ACFIC with non-members before and after the world financial crisis of 2008–09 which induced a significant change in government objectives. Before that crisis when priority in government objectives was “outward” (to stave off balance of payments crises that had befallen many other developing countries), ACFIC member firms were able to engage in exports and foreign investment to a greater extent than non-member firms, and even than those whose owners are members of the Congresses or Chinese Communist Party. After viewing the crises in international markets, and government objectives had turned more “inward”, ACFIC members were more likely to focus on domestic sales and investments.  相似文献

以纳税信用评级披露作为一个天然外生冲击,并基于2013—2016年1214家A股上市公司的微观数据构造准自然实验,使用双重差分法系统评估纳税信用评级结果披露对上市公司研发投入的影响。结果发现:纳税信用评级结果披露显著增加了上市公司的研发投入。基于PSM-DID方法的估计结果与上述结论无明显差异。稳健性检验也表明上述结论的正确性。机制检验表明,纳税信用评级结果披露通过降低企业的融资约束,进而促进企业增加研发投入。此外,分样本回归发现纳税信用评级结果披露只能对中小型企业和民营企业的研发投入产生促进作用。  相似文献
