外商直接投资与东亚金融危机——一个新的分析视角

关于东亚金融危机爆发原因的研究很多。但是大多数研究没有注意到FDI的大量流入对于东亚国家爆发金融危机的影响。虽然FDI没有直接引起金融危机的爆发,但是它确实对危机国家经济脆弱性的形成发挥了作用。FDI给东道国带来的金融风险往往是潜在的,如果不能有效监管,这种潜在金融风险就有转化成现实金融风险的可能。所以,一味提高FDI的引资比重并不能使发展中国家摆脱金融危机的侵扰,发展中国家有必要加强对FDI的监管。     

A decomposition of the predictive content of the term structure for output growth in Canada

The purpose of this study is to identify the underlying economic disturbances that drive the predictive content of the term structure for future output growth and those that may distort its information content. The study uses a structural vector autoregressive (VAR) model of a small and open economy for Canada that takes into account its relationship with financial markets in the USA and that Canada is a relatively large exporter of commodities. The model is used to decompose the sources of the variation of the slope of the yield curve and the correlation between the term spread and output growth. Monetary policy disturbances in both Canada and the USA, as well as short-term interest rates, are found to trigger excessive volatility in short-term rates and the term spread that do not contribute to the predictive content of the term spread for future output growth at horizons relevant for monetary policy analysis. However, innovations in output growth, inflation and other macroeconomic variables do not distort the forecast power of the term spread. Unlike the evidence for the USA, disturbances in nominal long-term yields are found to contribute about the same amount to the predictive content of the term spread as unexpected movements in monetary policy.     

The relationship between risk-neutral and actual default probabilities: the credit risk premium

The study investigates empirically the relationship between the risk-neutral measure Q and the real-world measure P. We study the ratio between the risk-neutral and actual default intensities, which we call the coverage ratio or the relative credit risk premium. Actual default intensities are derived from rating agencies annual transition matrices, while risk-neutral default intensities are bootstrapped from CDS quotes of European corporates. We quantify the average risk premium and its changes over time. Compared to related literature, special attention is given to the effects of the recent financial and European sovereign crises. We find that average credit risk premia rose substantially and that post-crisis levels are still higher than those observed before the financial crisis. This observation is especially true for high-quality debt and if it persists, it will have an impact on corporates funding costs. The quantification and revision of risk premia contributes to the discussion of the credit spread puzzle and could give extra insights in valuation models that start from real-world estimates. Our work is furthermore important in the context of state aid assessment. The real economic value (REV) methodology, applied by the European Commission to evaluate impaired portfolios, is based on a long-term average risk premium.     

COMMON FACTORS OF THE EXCHANGE RISK PREMIUM IN EMERGING EUROPEAN MARKETS

Existing empirical evidence suggests that the Uncovered Interest Rate Parity condition may not hold due to an exchange risk premium. For a panel dataset of eleven emerging European economies we decompose this exchange risk premium into an idiosyncratic (country‐specific) element and a common factor using a principal components approach. We present evidence of stationary idiosyncratic and common factors. This result leads to the conclusion of a stationary risk premium for these countries, which is consistent with previous studies often documenting a stationary premium in advanced countries. Furthermore, we report that the variation in the premium is largely attributable to a common factor influenced by economic developments in the United States.     

Assessing the predictive power of financial spreads in the euro area: does parameters instability matter?

In the empirical literature there is wide consensus that financial spreads cannot constitute a broadly based assessment on future output growth and inflation because the bivariate estimated regressions are not stable over time and lead to relatively poor out-of-sample forecasting performance (e.g. J Econ Liter 41:788–829, 2003). This conclusion arised for the USA, as well as for several European countries. In this paper we check whether the marginal predictive content of some financial spreads (the slope of the yield curve, the reverse yield gap and the credit spread) for macroeconomic forecasting in the euro area can be recovered using techniques taking into account potential parameters instability. We set up a quarterly Bayesian vector autoregression model with time-varying coefficients, comprising both target variables, as well as other monetary policy indicators, to serve as a benchmark. Then, the properties of the spreads as leading indicators are assessed by augmenting this benchmark BVAR with the spreads, one at a time. We find time variation of the coefficients to be a relevant issue in our model, especially for forecasting output growth, but financial spreads continue to have no or negligible marginal predictive content for both output growth and inflation. Overall, our results confirm that there is no ready-to-use financial spread that can replace an encompassing multivariate model for the prediction of target variables in the euro area.      

Another Look at the Equity Risk Premium Puzzle

The model of Mehra and Prescott (1985, J. Econometrics, 22, 145–161) implies that reasonable coefficients of risk‐aversion of economic agents cannot explain the equity risk premium generated by financial markets. This discrepancy is hitherto regarded as a major financial puzzle. We propose an alternative model to explain the equity premium. For normally distributed returns and for returns far away from normality (but still light tailed), realistic equity risk premia do not imply puzzlingly high risk aversions. Following our approach, the ‘equity premium puzzle’ does not exist. We also consider fat‐tailed return distributions and show that Pareto tails are incompatible with constant relative risk aversion.     

金融危机背景下银行类股票β值及其稳定性的实证检验

在金融研究中,风险和收益、个股与整个股市的波动一直是人们最为关注的问题。特别是在2007年8月美国次贷危机迅速蔓延后,各个公司更加重视股市波动的研究,以求最大限度地规避风险、获得最大收益。在金融研究中,人们通常用期望值表示收益,用方差和标准差来衡量风险。而在两者的关系研究中,资本资产定价模型反映了均衡状态下单个证券的预期回报与其相对市场风险值之间的关系,也描述了证券的风险溢价与市场组合风险溢价之间的关系。选择金融危机迅速传播后的2007年8月到2011年10月21日为研究时间段,选择上海证券交易所A股市场的浦发银行（600000）等14只银行类股票为研究对象,确定它们的值,研究银行类股票与整个股市波动的相关性,说明它们的风险溢价与市场组合风险溢价之间的变动关系。考虑到在所选时间段中,2010年3月开展的融资融券业务可能会对股票值的稳定性有所影响,因此,在求出这些股票的值后,还对这些股票值的稳定性进行了Chow检验。     

The central bank as shaper and observer of events: The case of the yield spread

The yield spread has commonly been employed as a successful predictor of economic growth and recessions, although its marginal predictive power has decreased since the 1990s. Notably, the yield spread's declining power to predict US economic activity coincided with its growing power to predict US interest rate changes. In my view, these phenomena are inevitably linked and share one cause. The central bank intended to enhance both its transparency and credibility through greater information disclosure; this disclosure improved interest rate predictability but might also have crowded out useful private information formerly in the yield spread that helped predict economic activity.     

Euro area sovereign yield spreads as determinants of private sector borrowing costs

We regress long-term private-sector borrowing rates on a money market rate, a term premium and credit risk. As a contribution to the current debate about European safe assets, our interest is in quantifying the impact of euro area sovereign bond spreads on private-sector lending by employing it as a proxy for private-sector credit risk. Panel estimates show significant, albeit rather small long-run effects. Another finding is large cross-country heterogeneity. Using linear country-specific estimates, we find the effect to be significant in only some countries, but the size of the maximum effect in these countries exceeds the average one more than three-fold. Furthermore, for one country, we find an asymmetrical effect with positive spread changes having greater impact on private-sector borrowing costs than negative ones. Substantial heterogeneity of the spillover effect between euro area countries indicates the presence of financial valuation effects based not only on economic fundamentals. This, in turn, implies that spillovers may entail contagion costs. Overall, our results suggest that these costs are considerable in the euro area and will remain so until an effective form of European safe assets is created.

International co-movements of real and financial economic variables

This study presents a first attempt at investigating whether the international co-movements of real economic activity conform to the same international co-movements of financial activity. This study tests the international co-movements of real economic activity, on the one hand, and financial variables such as stock returns, interest rates, inflation rates and risk premiums, on the other hand. We employ a dynamic correlation model on data from OECD countries for the period 1980–2010. Our findings demonstrate that international stock markets co-react in accordance with the underlying international economic forces. We also document three other results. First, the correlation among countries with respect to real economic activity is statistically positive, but the level of this correlation is lower than that of financial variables. Second, there is a significant increase over time in the international correlation level with respect to the financial variables. Finally, the creation of the Euro Monetary Union and the adoption of an inflation targeting policy in many countries have increased the international correlation of all of the financial variables tested. The article concludes with two implications from these findings: (1) predictions in the context of international portfolio diversification, and (2) policy making at the fiscal and monetary levels.     

MARKET DISCIPLINING OF THE DEVELOPING COUNTRIES' SOVEREIGN GOVERNMENTS

In this article, we contribute to the current literature on market disciplining of the sovereign governments of the developing countries by distinguishing both sides of the market discipline hypothesis by adopting three‐stage least square estimation to incorporate the contemporaneous feedback effects between primary structural budget balances and the country's default‐risk premiums. We provide empirical evidence of a unidirectional causal relationship between a country's default‐risk premium and primary structural budget balances with the direction flowing from primary structural budget balances to country's risk premium in 40 developing countries over the period 1975–2008. We also employ the Arellano‐Bond dynamic panel generalized methods of moments estimation to control for this joint determination of primary structural budget balances and the country's default‐risk premium, and find supportive evidence of undisciplined sovereign governments and of nonlinearly behaving well‐functioning financial markets in the sample countries.

Risk premium,macroeconomic shocks,and information technology: an empirical analysis

This study empirically identifies the impact of various macroeconomic factors on the default risk premium. Using monthly data for the period 1970–2010 for the US, our estimations indicate that the monetary policy aggregates, risk-free interest rate, term structure of interest rates, inflation, and the state of the business cycle influence the risk premium. The results also provide some evidence in support of the hypothesis that the development of information technology has had a decreasing impact on the risk premium. As expected, various financial crises have had substantial and long-lasting effects on the premium. The results suggest that the direct impact of the subprime crisis and Lehman’s collapse on the risk premium was as large as two and a half percentage-points for a sustainable period. Foreign financial crises, in turn, have lowered the risk premium in the US market, suggesting a flight-to-safety phenomenon.     

Financial crises and time-varying risk premia in a small open economy: a Markov-switching DSGE model for Estonia

Under a currency board, the central bank relinquishes control over its monetary policy and domestic interest rates converge towards the foreign rates. Nevertheless, a spread between both usually remains. This spread can be persistently positive due to elevated risk in the economy. This paper models that feature by building a DSGE model with a currency board, where the domestic interest rate is endogenously derived as a function of the foreign rate, the external debt position and an exogenous risk premium component. Time variation in the volatility of the risk premium component is then modelled via a Markov-switching component. Estimating the model with Bayesian methods and Estonian data shows that the economy does not react much to shocks to domestic interest rates in quiet times but is much more sensitive during crises, and matches the financial and banking crises, which cannot be captured by the standard DSGE model.     

Forecasting recessions using financial variables: the French case

In this article, we focus on the ability of two financial variables—the yield curve spread and the euro–US dollar exchange rate—to predict French recessions over the period 1979–2010. First, we propose a turning point chronology for the French business cycle based on a classical conception of economic cycles and a non-parametric dating algorithm applied to the real GDP series. Second, static and dynamic probit models are developed and estimated to produce the recession probabilities. In-sample results show that the dynamic specification performs better than the static one and, above all, that the exchange rate has a stronger predictive power than the yield curve. Out-of-sample results finally confirm the predominant role assigned to the exchange rate in predicting the latest recession occurred in 2008.     

The mortgage spread as a predictor of real-time economic activity

We analyse the predictive content of the mortgage spread for US economic activity. We find that the spread contains predictive power for real GDP and industrial production. Furthermore, it outperforms the term spread and Gilchrist–Zakraj?ek credit spread in a real-time forecasting exercise. However, the predictive ability of the mortgage spread varies over time.     

经济资本在商业银行信用风险计量中的应用

2008年的金融危机爆发后,信用风险成为理论界的关注热点,如何准确和合理的计量出信用风险是亟待解决的问题。用经济资本的计量方法对商业银行的信用风险进行管理是一个新的研究思路。经济资本作为一种风险管理的工具,用它来配置和量化信用风险的非预期损失在一定程度上使得信用风险的管理更加精确化和规范化。此外,将经济资本计量方法融入贷款项目的评估中得到的风险调整绩效,能够避免单纯的从会计账面价值角度评估项目而忽视风险的差别。     

Business Cycle Synchronization in EU: A Time‐Varying Approach

This article investigates the time‐varying correlation between the EU12‐wide business cycle and the initial EU12 member‐countries based on Scalar‐BEKK and multivariate Riskmetrics model frameworks for the period 1980–2012. The paper provides evidence that changes in the business cycle synchronization correspond to major economic events that have taken place at a European level. In the main, business cycle synchronization until 2007 had moved in a direction positive for the operation of a single currency, suggesting that the common monetary policy was less costly in terms of lost flexibility at the national level. However, as a result of the Great Recession of 2007 and the subsequent Eurozone Crisis, a number of periphery countries, most notably Greece, have experienced desynchronization of their business cycles with the EU12‐wide cycle. Nevertheless, for most countries, any questions regarding the optimality and sustainability of the common currency area in Europe should not be attributed to a lack of cyclical synchronization.     

Disentangling the Predictive Power of Term Spreads under Inflation Targeting

Under inflation targeting, S. Cho and J. Lee (2014, Inflation targeting and predictive power of term spreads. Seoul Journal of Economics, 27, 391–419), A. Estrella (2005, Why does the yield curve predict output and inflation? The Economic Journal, 115, 722–744) and P.L. Siklos (2000, Inflation targets and the yield curve: New Zealand and Australia versus the US. International Journal of Finance &; Economics, 5, 15–32) have reported that the predictive power of yield spreads for future inflation decreases in inflation targeting countries. In this paper, we decompose the yield spread into the expectations hypothesis component and the term premium, and find that the decrease in the predictability is mostly due to the deterioration of information embedded in the expectations hypothesis component. Our finding reveals that if inflation targeting is successful in achieving its main goal, then the expectations for future inflation are anchored at the target inflation rate (or range), and thereby the predictive contents of the term spreads regarding future inflation decrease.     

The term structure of interest rates and the Mexican economy

Can the yield spread, which has been found to predict with surprising accuracy the movement of key macroeconomic variables of developed countries, also predict such variables for a developing country experiencing economic turmoil? This article presents empirical results that suggest significant forecasting ability for the yield spread for segments of the Mexican economy during the 1995–1997 period of economic volatility. The actual and predicted variable changes sometimes conflict with those experienced by developed countries in part because of the unusually close relationship between the Mexican Treasury and the Banco de México. Consequently, analysts and policy officials may exploit the forecast potential of the yield spread, but only in the context of evolving institutional considerations.
