肉类食品安全认知和选择行为

目前,消费者对肉类食品安全状况表示担忧,消费者对兽药残留、饲料添加剂、食品添加剂的不舍理使用,以及病畜肉问题关注程度较高。对风险程度较高的微生物污染关注程度较低。在购买肉类食品过程中。颜色、气昧等易于直接识别的特征是消费者用于判断肉类食品质量常用的质量信号,对价格、食品标簦所提供的质量信息的信任程度不高。政府应加强食品安全信息披露体系建设,为肉类食品生产者的安全生产行为提供激励。     

Nonlinear tail dependence in cryptocurrency-stock market returns: The role of Bitcoin futures

We investigate the median and tail dependence between cryptocurrency and stock market returns of BRICS and Developed countries using a newly developed nonparametric cumulative measure of dependence over the period January 4, 2016 – December 31, 2019 as well as before and after the introduction of Bitcoin futures on December 17, 2017. The new measure is model-free and permits measuring tail risk. The results highlight the leading role of S&P500, Nasdaq and DAX 30 in predicting BRICS and developed countries’ stock market returns. Among BRICS countries, BVSP shows a starring role in predicting stock market returns. BSE 30 is the most predictor of cryptocurrencies, which have a little predictability on stock market returns. Ethereum has the leading role in predicting cryptocurrencies and stock market returns followed by Bitcoin. Tail dependence shows substantial role of S&P500, Nasdaq and BVSP in predicting stock market returns. Subsample analysis show the role of Bitcoin futures in reshaping the mean and tail dependence between cryptocurrency and stock market returns. Our results have important policy implications for portfolio managers, hedge funds and investors.     

高等教育融资的制度变迁与融资对策

我国的国情是“穷国”办了世界最大规模的教育,教育融资不足的问题是制约我国公立高等教育发展,乃至影响整个经济发展和社会进步的极为重要的课题.针对公立高等教育的准公共产品属性,我国公立高等教育融资需要国家、社会、学校及学生多主体同步推进,逐步加以解决.国家应该承担起教育投入的主要责任,合理规避高校贷款的融资风险;作为有益补充,学校可以采用稳步推进BOT融资等市场化融资手段,同时建立和完善“资本投资式”的助学贷款机制,减轻政府的财政负担.     

基于风险管理的石油公司内部控制自我评价研究

从美国COSO报告到2008年我国财政部等五部委发布的《企业内部控制基本规范》,说明我国企业内部控制已经制度化,但内部控制的有效性还需要建立一套企业内部控制自我评价体系,文中结合石油公司内部控制,从风险管理的角度研究了石油公司内部控制自我评价体系,为我国企业内部控制自我评价的实务提供参考。     

银行监督、企业社会性成本与贷款融资体系

本文从政府机构控股国有企业所造成的企业行为扭曲的角度来研究银行贷款策略组合的微观机制,即银行对国有企业和私营企业进行事前筛选的程度及贷款利率设定,并建立了关于银行贷款融资体系的微观模型和理论框架。首先,将企业社会性成本和银行监督功能(事前筛选)引入债务合同模型,说明国有企业在面临破产做清算决策时会考虑到社会破产成本,从而推导出国有企业的还款机制有别于私营企业,信息不对称条件下银行事前对贷款筛选的激励也会有所不同,并提供了一般性推导和数值解拟合分析;同时,事前筛选存在一定的反转效应,因此需要就监督效率的社会剩余价值进行权衡。     

互联网金融发展及对我国居民金融理财行为影响——柳州视角

当前互联网金融的迅速发展正在改变着整个金融生态,也在不断影响并改变着居民的理财行为.本文简要介绍互联网金融的含义,并总结当前互联网金融发展的特点,根据随机调查结果,分析了互联网金融对我国居民金融理财行为的影响.由于互联网金融并未被全民接受,相关政府监管部门应加强宣传,明确职责,完善监管体制,发挥互联网金融对经济金融发展的积极作用.     

我国高校财务管理问题与对策研究

进入21世纪以来,随着高等教育改革的不断深入,我国高校办学规模逐步扩大,办学条件得到明显改善,随之而来的是对教育经费需求的大量增加。而国家财政对教育拨款有限,高校只能以银行贷款来弥补教学经费的不足,这导致债务利息成为高校的沉重负担,高校财务风险管理的是否有效已经严重影响高校发展。     

European systemic credit risk transmission using Bayesian networks

The analysis of systemic credit risk is one of the most important concerns within the financial system. Its complexity lies in adequately measuring how the transmission of systemic default spreads through assets or financial markets. The transmission structure of systemic credit risk across several European sectoral CDS is studied by dynamic Bayesian networks. The new approach allows for a more advanced analysis of systemic risk transmission, including long-term and more complex relationships. The modelling reveals as relevant only relationships between the original series and one- and two-lagged series. Network structure learning displays a robust and stationary underlying risk transmission structure, pointing to a consolidated transmission mechanism of systemic credit risk between CDSs. Between 5 % and 40 % of sectoral CDS series variances are explained by the network relationships. The modelling allows us to ascertain which relationships between the CDS series show positive (amplifier) and negative (reducer) effects of systemic risk transmission.     

Regulation of a Risk Averse Firm

We extend the Laffont–Tirole regulation model to the case of risk-averse firms. Our main results are:

• The impact of risk aversion is to shift the optimal contract toward a cost-plus contract.

• As compared with the risk-neutral case, distortions are greater and informational rents are smaller.

• For high levels of risk aversion, the optimal contract involves cost ceilings and the less efficient firms are bunched together.

Reducing reporting risk: Designating foreign currency forward contracts as cash flow hedges

We present an example that compares the effects on earnings of designating a foreign currency forward contract as either a cash-flow or fair-value hedge of a foreign currency denominated receivable. Entities engaging in exchange transactions not denominated in their functional currency frequently enter into foreign currency forward contracts in order to mitigate their foreign exchange rate risk exposure. The aggregate effect on earnings of the transaction gain or loss on the foreign currency receivable and the gain or loss on the forward contract is known on the date the forward contract is initiated. The effect on each period’s earnings during the term of a forward contract designated as a cash-flow hedge is also known on the date the contract is initiated; whereas the effect on each periods’ earnings from a fair-value hedge cannot be determined until the respective balance sheet dates. Therefore, designating forward contracts as cash-flow hedges may suppress volatility in reported earnings compared to designating forward contracts as fair-value hedges. In addition, the reporting risk (the amount of uncertainty surrounding the pending measure of an item to be reported in the financial statements) is lower when a forward contract is designated as a cash-flow hedge relative to designating it as a fair-value hedge. This suggests foreign currency forward contracts designated as cash-flow hedges are more consistent with the purpose of hedge accounting: to mitigate the effects on earnings of applying different measurement criteria for the hedge and the hedged item.
