国有企业“债转股”政策:功能缺陷与制度依赖——项基于国有企业“债转股”政策跟踪调查的研究

伴随着我国经济体制改革向纵深发展,国有企业负债比率过高的问题更加突出显示出来。为了解决这个问题,我国实施了“债转股”政策。本文讨论四个命题:(1)国有企业是负债比率过高还是收益率过低;(2)“债转股”政策究竟是使国有企业“财务解困”还是“体制解困”;(3)“债转股”政策究竟是转移金融风险还是化解金融风险;(4)资产管理公司为国有企业和国有商业银行解困,将来谁为资产管理公司解困。本文认为“债转股”政策设计存在功能缺陷与制度依赖。国有企业“债转股”政策的成功依赖于国有企业(商业银行)现代企业制度的建立与完善。

ADMISSIBILITY OF GENERIC MARKET MODELS OF FORWARD SWAP RATES

Our main goal is to re‐examine and extend certain results from the papers by Galluccio et al. and Pietersz and van Regenmortel. We establish several results providing alternate necessary and sufficient conditions for admissibility of a family of forward swaps, that is, the property that it is supported by a (positive) family of bonds associated with the underlying tenor structure. We also derive the generic expression for the joint dynamics of a family of forward swap rates under a single probability measure and we show that these dynamics are uniquely determined by a selection of volatility processes with respect to the set of driving martingales.     

Cross-hedging strategies between CDS spreads and option volatility during crises

This paper presents a joint analysis of the term structure of credit default swap (CDS) spreads and the implied volatility surface for five European countries from 2007 to 2012, a sample period covering both the Global Financial Crisis (GFC) and the European debt crisis. We analyze to which extent effective cross-hedges can be performed between the credit and equity derivatives markets during these two crises. We find that during a global crisis a breakdown of the relationship between credit risk and equity volatility may occur, jeopardizing any cross-hedging strategy, which happened during the GFC. This stands in sharp contrast to the more localized European debt crisis, during which this fundamental relationship was preserved despite turbulent market conditions for both the CDS and volatility markets.     

去产能企业债转股的市场化机制研究

按市场化原则实施"债转股"是巩固2015年至今去产能的阶段性成果、建立化解过剩产能的长效机制、妥善处置去产能企业债务问题的有效途径之一。实现去产能企业的市场化运作,需要客观分析去产能企业债务状况的变化,准确把握去产能企业债务结构的特殊性,明确对去产能企业实施债转股的前提条件,从按市场化原则选择债转股实施对象、确定债转股价格、筹集债转股资金、确定持股人地位、确定股权退出方式、明确非金融债务债转股准则六个方面入手,有效推进去产能企业债转股市场化机制的建立。     

利率互换定价存在的障碍及解决办法

根据我国利率互换市场现状,着重分析我国利率互换定价目前存在的障碍,阐述一种可行的定价方法,通过拟合交易所国债的利率期限结构计算出远期利率代替未来浮动端的参考利率确定浮动端现金流,令利率互换固定端现金流与之相等,得出固定利率。定价结果表明本文阐述的方法能够提供一种较为有效的对利率互换定价的方法,可以作为实际交易过程中的定价参考。     

AIG在次贷危机中所扮演的角色及其启示

美国的次贷危机已经演变成波及全球的金融危机,在此次危机中有许多国际知名的金融企业陷入困境,其中就包括美国国际集团（AIG）。作为全球首屈一指的保险业巨头,AIG在次贷危机中由于流动性不足,从一家纯粹的私人企业变成了“半国有化”的企业,其根源在于制度层面的投资过度集中、风险管理缺失、创新工具滥用,和技术层面的数据充足性、假设准确性、模型有效性等问题。     

债转股中的若干问题探析

在债转股中,金融资产管理公司应以"治理结构"为目标;要建立以AMC为主,银行为辅的共同行使债转股企业选择权的体制,并遵循"效率优先、适度公平"的原则;要以市场化的手段来重组企业;应从制度上规定AMC对债转股企业的绝对控股权.     

Effect of the Sovereign Credit Ratings in East Asia Countries: Evidence from Panel Vector Autoregression

We study the effect of the sovereign credit ratings on the economies of seven East Asian countries, applying panel vector autoregression (VAR). We find that rating has less effect than outlook of rating on the credit default swap (CDS) spreads, the stock indexes, and the GDP growth rates. Rating upgrade and positive outlook have stronger effects than rating downgrade and negative outlook, and the effects of positive outlook and rating are greater after the financial crisis. There is evidence of contagion in that the economic variables of a country seem to have been affected by the outlooks of the other countries.     

HEDGING STRATEGIES AND MINIMAL VARIANCE PORTFOLIOS FOR EUROPEAN AND EXOTIC OPTIONS IN A LÉVY MARKET

This paper presents hedging strategies for European and exotic options in a Lévy market. By applying Taylor’s theorem, dynamic hedging portfolios are constructed under different market assumptions, such as the existence of power jump assets or moment swaps. In the case of European options or baskets of European options, static hedging is implemented. It is shown that perfect hedging can be achieved. Delta and gamma hedging strategies are extended to higher moment hedging by investing in other traded derivatives depending on the same underlying asset. This development is of practical importance as such other derivatives might be readily available. Moment swaps or power jump assets are not typically liquidly traded. It is shown how minimal variance portfolios can be used to hedge the higher order terms in a Taylor expansion of the pricing function, investing only in a risk‐free bank account, the underlying asset, and potentially variance swaps. The numerical algorithms and performance of the hedging strategies are presented, showing the practical utility of the derived results.
