论经济新闻人才培养的路径创新

财经传媒热及大众媒体的“经济化”,使经济新闻及传媒人才走俏。财经院校依托经济管理的学科优势培养经济新闻人才,应寻求经济管理学科与新闻学之间的契合点,处理好一般新闻学课程与经济新闻类课程的衔接关系,并强化实践教学和就业方向,以突出经济新闻专业特色,力戒“泛化”、“软化”和“硬化”。     

How does news sentiment affect the states of Japanese stock return volatility?

This paper examines the impact of public news sentiment on the volatility states of firm-level returns on the Japanese Stock market. We firstly adopt a novel Markov Regime Switching Long Memory GARCH (MRS-LMGARCH), which is employed to estimate the latent volatility states of intraday stock return. By using the RavenPack Dow Jones News Analytics database, we fit discrete choice models to investigate the impact of news sentiment on changes of volatility states of the constituent stocks in the TOPIX Core 30 Index. Our findings suggest that news occurrence and sentiment, especially those of macro-economic news, are a key factor that significantly drives the volatility state of Japanese stock returns. This provides essential information for traders of the Japanese stock market to optimize their trading strategies and risk management plans to combat volatility.

基于共同冲击和异质风险叠加传导的风险传染研究——来自中国上市银行网络的传染模拟

本文将银行系统遭遇外部共同冲击作为研究起点,建立了一个共同冲击和异质风险交互传导与放大的简化模型,冲击的传导包括“原始冲击”、“增量冲击”和“违约冲击”三个风险传染阶段。基于2018年我国15家上市银行的股票收益率和年报数据、2006年至2018年的银行评级数据,本文构建了贝叶斯分层图模型和银行间拆借矩阵,并利用蒙特卡洛模拟测度不同触发银行所引发的系统性风险损失、单个银行的系统性风险杠杆能力(文中定义为“传染乘数”指标)以及政府监管介入的效果。模拟结果显示:共同冲击损失远大于异质风险损失;规模和网络关联性是决定传染乘数的重要因素,且当规模因素不突出时,网络关联性对传染乘数的决定作用相对更强,极容易出现小规模、高关联性银行具有较高的传染乘数;当银行风险资产损失率在10%至25%之间时,造成系统性风险损失的杠杆能力普遍增强;政府监管介入能较好地降低系统性风险。本研究的相关结论为系统性风险的监管设计提供经验证据和参考。     

Commodity markets through the business cycle

From 2008 to 2011, commodity markets experienced growing attention from the banking industry for various reasons: the summer 2008 oil price swing, the price surge in an ounce of gold, or sharp variations in agricultural prices. As a consequence, can we hypothesize the existence of a global connection between commodities and economic cycles? If these recent events suggest that commodity markets are strongly related to the business cycle, this evidence goes nevertheless against the widespread intuition that commodity markets are a strong source of diversification in a standard cash–bond–equity portfolio. Based on a data-set from 1990 to present, this paper investigates this issue by (i) looking at the reaction of commodity markets to economic news, and (ii) using a Markov regime-switching model to analyse economic regimes and commodity markets as an asset class.     

信贷配给、流动性冲击和民营企业现金持有

融资约束的存在要求企业持有必要的现金以预防可能的流动性冲击。不同于以往研究,本文从融资数量的硬约束——信贷配给视角将企业现金持有水平及其经济后果的考察纳入到一个统一的理论框架,并运用实证的方法研究流动性冲击下我国民营上市公司的现金持有行为。研究表明：民营上市公司持有高额现金的原因出于在信贷配给约束下的预防性动机;在遭受流动性冲击时,增持现金对民营上市公司具有正向的价值效应,且信贷配给水平越高的企业这种正向效应越显著。     

Policy coordination among the ASEAN-5: A global VAR analysis

This paper aims to analyse the feasibility of policy coordination among the ASEAN-5 economies. This is done by determining whether they experience symmetric responses to common shocks. Given that the problem of dimensionality plagues large-scale macroeconomic modelling, a Global VAR model by Pesaran, Schuermann, and Weiner (2004) and Dees, Mauro, Pesaran, and Smith (2007) is used. The results in this paper provide some weak evidence of symmetric responses to the common (global) shocks of interest: a US monetary policy shock, a US output shock, a Chinese output shock; an oil price shock. Shocks from the US produced the most symmetric responses. The lack of symmetry in some cases has implications for further policy coordination. Since migrant remittances could provide an adjustment mechanism, further labour market integration is needed as it currently lags behind trade and financial integration in the region.     

News-driven international credit cycles

How does news about future economic fundamentals affect within-country and cross-country credit allocation? How effective is unconventional policy when financial crises are driven by unfulfilled favorable news? I study these questions by employing a two-sector, two-country macroeconomic model with a banking sector in which financial crises are associated with occasionally binding leverage constraints. In response to positive news on the valuation of non-traded sector capital which turns out to be incorrect at a later date, the model captures the patterns of financial flows and current account dynamics in Spain between 2000–2010, including the changes in the sectoral allocation of bank credit and movements in cross-country borrowing during the boom and the bust. When there are unconventional policies by a common authority in response to unfulfilled favorable news, liquidity injections perform better in ameliorating the downturn than direct assets purchases from the non-traded sector.     

Press freedom and jumps in stock prices

Press freedom varies substantially across countries. In a free environment, any news immediately becomes public knowledge through mediums including various electronic media and published materials. However, in an unfree environment, (economic) agents would have more discretionary powers to disclose good news immediately, while hiding bad news or releasing bad news slowly. We argue that this discretion affects stock prices and that stock markets in countries with a free press should be better processors of economic information. Using an equilibrium asset-pricing model in an economy under jump diffusion, we decompose the moments of the returns of international stock markets into a diffusive risk and a jump risk part. Using stock market data for a balanced panel of 50 countries, our results suggest that in countries with a free press, the better processing of bad news leads to more frequent negative jumps in stock prices. As a result, stock markets in those countries are characterized by higher volatility, driven by higher jump risk and more negative return asymmetry. The results are robust to the inclusion of various controls for governance and other country- or market-specific characteristics. We interpret these as good stock market characteristics because a free press improves welfare and increases economic growth.     

广义转型视角下的制度移植——日本明治维新与俄罗斯休克疗法的比较研究

从广义上来说,转型是从一个社会成熟状态向另一个社会成熟状态的转变。通过移植先进国家的制度来推动制度变迁是实现转型的一种重要方式。在历史上,制度移植既有成功的经验,也有失败的教训。通过对日本明治维新和俄罗斯休克疗法的比较,文章认为,成功的制度移植需要注重对慢动制度的诱导。而教育、示范、学习乃至奖惩等方式在诱导慢动制度变革方面可以发挥重要的作用,从而为制度移植的成功提供保障。在此基础上,文章进一步分析了俄罗斯转型的发生机理和绩效。
