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

党的十九届五中全会提出了到2035年人均GDP达到中等发达国家水平的远景目标,因此测算和回答能否和如何如期实现该目标,对于我国实现第二个百年奋斗目标和坚持“四个自信”具有重要的意义。为此,本文根据跨越和陷入“中等收入陷阱”经济体的发展经验,对2021—2035年我国潜在增长率变化进行了测算。一是参照跨越和陷入“中等收入陷阱”经济体在我国相同发展阶段时各主要生产要素的变化,模拟设定我国未来各主要生产要素的增长率;二是通过运用附加人力资本的增长核算模型测算基准、乐观和悲观三种不同情境下未来我国经济的潜在增长率,验证我国2035年发展目标实现的可能性;三是依据主要要素对潜在增长率的贡献度,提出我国如期实现2035年发展目标的相应政策建议。 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

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

Enhanced Special Drawing Rights: How China Could Contribute to a Reformed International Monetary Architecture 下载免费PDF全文
Since the end of the Bretton Woods era, the world has operated on a de facto system of free‐floating exchange rates, with the US dollar as the dominant international currency. The system, characterized by large pro‐cyclical capital flows and chronic imbalances, is inherently unstable, and has contributed to repeated crises, recessions and geopolitical tensions. One potentially “least‐difficult” line of reform would be to allow the evolution of a multi‐currency system, underpinned by an expanded role for Special Drawing Rights (SDRs). Attempts to promote wider use of the SDR have foundered on the liquidity premium. However, for Chinese corporations and institutions, at present restricted in their capital account activities, the SDR liquidity premium would appear less daunting. The Chinese authorities could provide policy encouragement for the use of SDRs by their institutions. This initiative, supported by China's Special Administrative Region Hong Kong, would kick‐start an international SDR ecosystem, and encourage even broader use of SDRs, to the benefit of international monetary stability. 相似文献

With sluggish external demand and increasing trade protectionism by the USA and the European Union, China is facing severe challenges in implementing its deeper, ongoing reforms. To respond actively to such challenges, the Communist Party of China's 19th National Congress proposed to “promote a new pattern of all‐round opening up.” In particular, the establishment of free trade ports is considered an important means to realize deeper integration with the world economy. This paper discusses the background, the motivation, the possible challenges as well as a feasible path for the successful implementation of free trade ports in China. Based on the international experience, the construction of free trade ports in China requires freer trade in goods, high mobility of talent and free capital flow. 相似文献

We examine the relationship between the role of trade finance availability and the export intensity of foreign subsidiaries of multinational enterprises (MNEs). In developing our hypotheses, we draw upon insights derived from “new” internalisation theory (international business literature) and international trade finance (international economics literature). We empirically test these hypotheses using survey data compiled from subsidiary managers in six ASEAN countries, supplemented with host-country level data. We conceptualise, empirically test, and establish that the subsidiary-level capability in combining and utilising internal and external debts is an important subsidiary-specific advantage to support export intensity. We find that subsidiaries employ intra-firm loans from MNE internal capital markets and, to some extent, bank loans from external financial institutions to boost their export intensity. Subsidiaries may have concerns about foreign exchange risks, but the use of appropriate foreign exchange risk management is positively associated with export intensity. We discuss the implications of our findings for theory and practice. 相似文献

ABSTRACTConcerns about the effects and consequences of climate change have notably increased in recent decades. Despite large advances in the understanding of this phenomenon, further research into the determinants of gas emissions is necessary, to shed light on the responsibilities of producers and consumers, and their potential contribution to mitigation strategies. This paper studies the trajectories and determinants of carbon embodied in world trade during a period of 15 years. Our methodology relies on a multiregional input–output model, environmentally extended. Drawing on data from the World Input–Output Database, we estimate embodied emissions in bilateral flows. Then, we assess the determinants of CO2 emissions embodied in trade, combining input–output modelling with trade gravity panel data analysis. This paper offers a methodological approach that explains and quantifies the underlying factors of carbon trade, integrating the production and consumption perspectives and considering the geographical, structural and institutional context of countries. 相似文献
