我国国债二级市场的流动性分析

国债流动性在现代国债有效市场机制和效率管理中具有十分重要的地位,它对降低债务风险、提高国债管理效率和充分发挥国债二级市场的经济调控功能都具有重要意义。与发达国家相比,我国国债的流动性处于较低的水平。本文对此问题进行了分析。并提出相应的对策。

对凭证式国债发行工作的几点思考

凭证式国债是国家发行的一种重要金融债券,对支持我国经济的发展发挥了重要作用。近年来,凭证式国债在发行过程中出现了许多问题,亟需采取措施加以解决,譬如,可以采取加强金融监管、加大连规操作的处罚力度、扩大延续性宣传、调整国债发行手续费等方法,以确保其能够顺畅发行。     

Why do companies issue convertible bond loans? An empirical analysis for the Canadian market

To identify issuer motives, we study the determinants of announcement effects of convertible debt issues in the Canadian market. Classified into equity‐ and debt‐like, wealth effects are significantly more negative for equity‐like convertible bond issuers. Equity‐like convertibles are significantly negatively affected by agency costs of equity. However, agency costs of debt have no significant effect on debt‐like convertibles. Consistent with Stein (1992), this suggests convertibles in particular represent a substitute for equity. Moreover, convertible debt offers announced by income trusts experience significantly less negative wealth effects than offers by nontrusts—a finding explained by a more debt‐like convertible design, very low agency costs of equity in case of income trusts, or both.

Pricing effects in Fannie Mae agency bonds

As a government-sponsored enterprise, Fannie Mae enjoys certain advantages over other firms. The extent of these advantages, while widely discussed, have not yet been fully quantified. This paper empirically examines the returns to Fannie Mae general obligation bonds under the assumptions of the Arbitrage Pricing Theory. The model provides an explicit method for estimating the risk premium on Fannie Mae bonds. The results indicate that liquidity and tax effects are important in explaining the returns to Fannie Mae bonds. The results also indicate that the market does not incorporate changes in the riskiness of the mortgage market into the returns on Fannie Mae bonds. The results provide support for the contention that Fannie Mae, as a government sponsored enterprise, enjoys a significant advantage over other firms in the capital market.

短期融资券发行利差结构分析

本文选取175只短期融资券为样本，研究各主要因素对短期融资券发行利差的影响。实证分析发现，短期融资券发行利差具有明显的期限结构，并受到发行规模、央票利率水平、企业性质和重大信用风险事件的显著影响，个另4行业和超大型企业也能享受一定的利差优惠。研究还表明，现阶段在发行人个体层面没有明显的利差结构性差异，表现为发行人财务指标对发行利差的影响不显著。     

上交所与银行间国债市场的新券效应及比较

新券效应与国债品种特征、投资者行为和市场微观结构均有密切关系。上交所和银行间国债市场的新券效应不仅存在共同点，也存在明显差异。在交易额占比最大的基准国债品种上，两个市场均表现出显著的新券效应。但由于投资者行为存在差异，上交所国债市场的新券效应更倾向于中长期国债品种，而银行间国债市场的新券效应更倾向于短期国债品种。而且，上交所国债市场的指令驱动交易方式便于连续交易和信息披露，方便考察新券效应，而银行间国债市场仅能在较短时间内考察新券效应。在上交所国债市场上，中长期国债与国债回购的利差更大，有利于现券回购套利投资，中长期新券吸引套利投资者积极参与，也促进了新券效应。     

A jump to default extended CEV model: an application of Bessel processes

We develop a flexible and analytically tractable framework which unifies the valuation of corporate liabilities, credit derivatives, and equity derivatives. We assume that the stock price follows a diffusion, punctuated by a possible jump to zero (default). To capture the positive link between default and equity volatility, we assume that the hazard rate of default is an increasing affine function of the instantaneous variance of returns on the underlying stock. To capture the negative link between volatility and stock price, we assume a constant elasticity of variance (CEV) specification for the instantaneous stock volatility prior to default. We show that deterministic changes of time and scale reduce our stock price process to a standard Bessel process with killing. This reduction permits the development of completely explicit closed form solutions for risk-neutral survival probabilities, CDS spreads, corporate bond values, and European-style equity options. Furthermore, our valuation model is sufficiently flexible so that it can be calibrated to exactly match arbitrarily given term structures of CDS spreads, interest rates, dividend yields, and at-the-money implied volatilities.     

The shortage of safe assets in the US investment portfolio: Some international evidence

This paper develops a Bayesian Global VAR (GVAR) model to track the international transmission dynamics of two stylized shocks, namely a supply and demand shock to US-based safe assets. Our main findings can be summarized as follows. First, we find that (positive) supply-sided shocks lead to pronounced increases in economic activity which spills over to foreign countries. The impact of supply-sided shocks can also be seen for other quantities of interest, most notably equity prices and exchange rates in Europe. Second, a demand-sided shock leads to an appreciation of the US dollar and generally lower yields on US securities, forcing investors to shift their portfolios towards foreign fixed income securities. This yields sizable positive effects on US output, equity prices and a general decrease in financial market volatility.
