The effect of offshoring on knowledge flows in the US automobile industry

This paper examines the impact of financial constraints on innovation for established firms. We make use of a direct measure of the existence of financial constraints obtained thanks to a specific survey addressed to French established firms. This is a distinctive feature of this paper as most of previous studies had to rely on proxies (like the cash-flow sensitivity), which may be subject to interpretation problems. The probability to have innovative activities and the probability to face financial constraints are simultaneously estimated by a recursive bivariate probit model. Accounting for the endogeneity of the financial constraint variable, we find that financial constraints significantly reduce the likelihood that firms have innovative activities. The probability to encounter financial constraints is explained by firms’ ex ante financing structure and economic performances.     

European quanto option pricing in presence of liquidity risk

In this paper, we study the pricing problems of the European quanto options in which the underlying foreign asset is in imperfectly liquid markets. First, we assume that the dynamics of the underlying foreign asset price are affected by market liquidity and propose a liquidity-adjusted quanto model. This allows for the effects of market liquidity on European quanto option pricing. And then we derive the analytical pricing formulas for four different types of European quanto options. Finally, we empirically investigate the pricing performance of our proposed model with a European quanto construction involving the SSE 50 ETF, as the underlying asset, and the CNY/HKD exchange rate. Empirical results demonstrate that the pricing accuracy of the proposed model is markedly superior to that of the Black-Scholes quanto model. In other words, allowing for liquidity risk in the framework of European quanto option pricing can make markedly improvements in fitting the real market data. Particularly, the improvement rate is high for medium-term and out-of-the-money options. Moreover, these results are robust for different liquidity measures.     

流动性、生命周期与投资组合相异性——中国投资者行为调查实证分析

本文采用Probit和Tobit模型对中国居民的股票市场参与和投资组合的影响因素进行了分析,主要有以下的实证发现:首先,不流动性资产特别是房地产的投资显著影响了投资者的股票市场参与和投资组合,而且影响以“替代”效应或者说“挤出”效应为主。其次,投资者在进行投资组合时极少利用股票市场对其未来现金流所承担的风险进行对冲,也就是说,中国居民投资的“生命周期效应”不明显;第三,中国居民投资的“财富效应”非常显著。财富的增加既增加了居民参与股票市场的概率,也增加了居民参与股票市场的深度。     

关于解决流动性过剩问题的初步思考

本文从流动性的内涵和外延入手,分析了我国流动性过剩的全球背景和我国流动性过剩的表现及结构性特点,提出了解决流动性过剩,要坚持"市场为主、各方联动、化多为少、化少为多、标本兼治、综合解决"的思路,指出当前重点是解决经常账户顺差过大,流动性过剩的来源问题,以及农村地区资金匮乏,导致资金配置结构性失衡的问题。     

量化宽松货币政策下美国的消费投资与全球流动性泛滥

美联储试图通过量化宽松货币政策的实施刺激国内私人部门消费和投资的增长。研究表明,由于美国经济的问题不是流动性短缺,因此,量化宽松货币政策不仅没有带来美国经济的复苏反而带来全球美元流动性泛滥,强化了全球经济运行的不稳定性和不确定性。作为国际货币的主要发行国,美国应该放弃这种与邻为壑的量化宽松货币政策,以保持全球经济和金融的稳定。     

数字普惠金融、知识产权保护与企业创新

加快实施创新驱动发展战略已成为社会各界重点关注的议题。本文将数字普惠金融、知识产权保护与企业创新置于同一框架下进行分析,研究发现：数字普惠金融与知识产权保护均有利于促进企业创新;知识产权保护对数字普惠金融与企业创新的关系具有负向调节作用。进一步分析发现：数字普惠金融主要通过降低信息不对称、融资约束与财务风险来促进企业创新;数字普惠金融的创新激励作用有利于提高企业的产品与资本市场表现、促进地区经济增长;异质性检验发现,知识产权保护对数字普惠金融与企业创新的调节作用具有“规模效应”“融资依赖效应”和“阶段效应”。研究结论不仅丰富了企业创新的相关文献,还为完善金融监管体系、优化知识产权环境提供了有益启示。     

Collusive Long-Run Investments Under Transmission Price-Caps

In the short run, constraints in the electricity transmission system may give market power to generators. This paper examines whether the constraints themselves are a long-run equilibrium outcome in a competitive environment. We show that independent transmission companies and generators can tacitly collude to raise prices to consumers and divide the resulting profits. We also show that price cap regulation does not prevent this behavior and may in fact contribute to it. The mechanism for collusion is that generators locate their plants so that a capacity-constrained transmission line lies between them and their consumer market. We show that this constraint-based collusion can be sustained in a static game without any punishment strategies.     

中国商业银行利率风险管理的约束与行为选择

中国商业银行为什么存在着利率风险管理的弱化?这种选择是否满足于商业银行在约束条件下最优的理性行为? 本文通过对中国商业银行利率风险管理的具体约束条件的分析,从成本收益角度,在理论上解释了中国商业银行行为的理性选择.     

融资融券对我国期指市场影响的实证研究

以融资融券对我国期指市场的影响为对象进行实证研究,发现融资融券对期指市场当日成交金额产生负向影响,对期指市场当日持仓量产生正向作用;融资融券交易与期指市场波动性之间不存在长期稳定的协整关系,也不存在确定的线性关系;融资融券交易对期指市场当日成交金额并不存在统计意义上的因果引致关系,当日融券余额与期指市场当日持仓量存在双向因果引致关系,期指市场波动性是融券余额的单向因果引致关系。因此,扩大融资融券标的范围与可供借贷证券池,发展有利于中小投资者参与的、与融资融券交易有关的风险对冲套利金融产品是我国证券市场转型的重要举措。     

企业ESG表现改善的技术创新促进效应研究

ESG表现的改善不仅能够显著提升企业形象,而且对企业可持续发展具有多重积极影响,包括融资约束缓解效应、代理成本减少笑效应、内部控制优化效应等,而这些积极效应又将促进企业的技术创新。采用沪深A股上市公司2011—2020年数据的分析发现：ESG表现的改善能够显著促进企业技术创新,且其中存在缓解融资约束、降低代理成本、优化内部控制等影响路径;ESG表现改善的技术创新促进效应因企业特征的不同而具有异质性,非国有企业比国有企业、重污染企业比非重污染企业更强,成长期和成熟期企业比初创期和衰退期企业更为显著;市场化程度对ESG表现改善的技术创新促进效应具有负向调节作用,在市场化水平较低、政府对市场干预程度较高、产品市场发育程度较低的地区企业ESG表现改善的技术创新促进效应较强。因此,一方面,应加快构建和完善中国特色ESG体系,推动企业积极实施ESG战略以及ESG信息披露数量和质量的提升;另一方面,应对不同类型、不同地区企业的ESG表现提出差异化要求,在强化外部监督的同时激励和支持各类企业的ESG投资。
