Contingent Liabilities and Sovereign Risk: Evidence from Banking Sectors 或有负债与主权风险:来自银行业的证据
Pub Date : 2012-10-01 DOI: 10.2139/ssrn.2142437

This paper proposes a simple method to estimate contingent liabilities that arise from (implicit and explicit) government guarantees to the banking sector. This method allows us to construct cross-country estimates on potential costs of bank failures. Furthermore, we empirically test whether the contingent liabilities from the banking sector is a significant determinant of sovereign risk based on the data from 32 countries. Our results suggest that a 1% of GDP increase in contingent liabilities is associated with an increase in sovereign CDS spreads of 24 basis points in advanced countries and 75 basis points in emerging economies.
本文提出了一种简单的方法来估计政府对银行业(隐性和显性)担保所产生的或有负债。这种方法使我们能够对银行倒闭的潜在成本进行跨国估算。此外,我们基于来自32个国家的数据,实证检验了银行业或有负债是否是主权风险的重要决定因素。我们的研究结果表明,或有负债每增加1%的GDP,发达国家的主权CDS息差就会增加24个基点,新兴经济体则会增加75个基点。

The Safe-Haven Effect in Forward Premia: What Makes a Currency Trustworthy? 远期溢价的避险效应:什么使一种货币值得信赖?
Pub Date : 2012-08-26 DOI: 10.2139/ssrn.2136698
Fangda Liu, P. Sercu
Recently, the role of safe-haven currency has become increasingly remarkable: in the time of stress, uncertainty aversion drives investors to shun the risky currencies and fly for quality. The currency that serves as a safe haven also acts as the benchmark for performance measurement. In this paper we explore what contributes to a safe-haven or benchmark image of currency in turbulence. By comparing floating rates to band-regime ones, strong base currencies to weak ones, and the base currencies with different market shares, we find that the benchmarking role primarily comes from currency' strength measured by interest rate differential. However a low interest rate is not sufficient. A trustworthy currency also has large share in FX markets as well, and in this sense our safe-haven effect is not a pure carry-trade-cycle effect. The exchange-rate regime seems to matter the least. Besides, we find that consistent with the idea that reputation comes from a slow-moving effect, the safe-haven evidence is especially present in the long-run-trend component of the forwardpremium.
最近,避险货币的作用变得越来越显著:在紧张时期,对不确定性的厌恶驱使投资者避开高风险货币,转向高质量货币。作为安全港的货币同时也是衡量业绩的基准。在本文中,我们探讨了是什么促成了货币在动荡中的避险或基准形象。通过对浮动汇率与浮动区间汇率、强势基础货币与弱势基础货币以及不同市场份额基础货币的比较,我们发现基准作用主要来自于以利差衡量的货币强弱。然而,低利率是不够的。一种值得信赖的货币在外汇市场上也占有很大的份额,从这个意义上说,我们的避险效应不是纯粹的套利交易周期效应。汇率制度似乎是最不重要的。此外,我们发现,与声誉来自缓慢移动效应的观点一致,避险证据尤其存在于远期溢价的长期趋势部分。

Banking Risk and Macroeconomic Fluctuations 银行风险与宏观经济波动
Pub Date : 2012-08-26 DOI: 10.2139/ssrn.2136699
Yi Jin, Zhixiong Zeng
This paper develops a model of banking frictions and banking risk. As a sort of systemic risk, changes in banking risk lead to fluctuations in aggregate economic activity. We decompose the macroeconomic effect of a banking risk shock into a pure default effect and a risk-aversion effect when risk sharing among investors is imperfect. When the shock generates a bank risk spread similar to the peak value during the Global Financial Crisis, the overall effect is a decline in employment by 4.66%. The default effect leads to a 3.40% employment decline by a “within-model” measure, and a 3.51 decline by a “between-model” measure. The remaining is attributed to the risk-aversion effect. A practical implication of our analysis is that by developing financial safety net and improving risk sharing among investors, the society can mitigate the adverse macroeconomic effects of banking risk shocks to some extent, but cannot eliminate all of them.
本文建立了一个银行摩擦与银行风险的模型。作为一种系统性风险,银行风险的变化会导致总体经济活动的波动。我们将银行风险冲击的宏观经济效应分解为纯违约效应和投资者风险分担不完全时的风险规避效应。当冲击产生的银行风险价差与全球金融危机期间的峰值相似时,总体影响是就业下降4.66%。通过“模型内”测量,默认效应导致就业率下降3.40%,通过“模型间”测量导致就业率下降3.51%。其余部分归因于风险规避效应。我们的分析的一个现实意义是,通过建立金融安全网和改善投资者之间的风险分担,社会可以在一定程度上缓解银行风险冲击的不利宏观经济影响,但不能完全消除银行风险冲击。

Liquidity Risk and Cross-Sectional Earnings-Returns Relation 流动性风险与横断面收益回报关系
Pub Date : 2012-08-16 DOI: 10.2139/ssrn.2130219
Zangina Isshaq, R. Faff
Employing a broad sample of US firms over the period 1962 to 2009, we provide evidence of a liquidity risk impact on the fundamental earnings-returns relation. Specifically, we document that current liquidity risk has a positive moderating effect on the relation between current returns and next period change in earnings. Notably, this effect is distinct from (and after controlling for) the negative effect observed for illiquidity level (Kerr, Sadka and Sadka, 2012). We further show that the liquidity risk effect on the earnings-returns relation is dominant in firms that: (a) are of intermediate size; (b) are of intermediate book-to-market; and (c) are profitable.
采用1962年至2009年期间美国公司的广泛样本,我们提供了流动性风险对基本收益-回报关系影响的证据。具体而言,我们证明当前流动性风险对当前收益与下一时期收益变化之间的关系具有正向调节作用。值得注意的是,这种影响与观察到的非流动性水平的负面影响不同(并且在控制之后)(Kerr, Sadka和Sadka, 2012)。我们进一步表明,流动性风险对收益回报关系的影响在以下公司中占主导地位:(a)中等规模的公司;(b)账面市值比为中等;(c)是盈利的。
