In a model of sovereign debt with endogenous default, we find a non-monotonic relationship between default risk and volatility, reflecting a trade-off between prudence and the insurance value of default. We show that this feature also holds in the data.  相似文献

This article employs threshold cointegration and error-correction models to the default risk premium. The approach allows asymmetry in the dynamic process that has not been captured in previous studies of corporate credit spreads. The results indicate that the adjustment process is asymmetric and would be beneficial to investors and macroeconomic forecasters as the default risk premium may signal future business cycles.  相似文献

We study the impact of decentralization on sovereign default risk. Theory predicts that decentralization deteriorates fiscal discipline since subnational governments undertax/overspend, anticipating that, in the case of overindebtedness, the federal government will bail them out. We analyze whether investors account for this common pool problem by attaching higher sovereign yield spreads to more decentralized countries. Using panel data on up to 30 emerging markets in the period 1993–2008 we confirm this hypothesis. Higher levels of fiscal and political decentralization increase sovereign default risk. Moreover, higher levels of intergovernmental transfers and a larger number of veto players aggravate the common pool problem.  相似文献

We develop a closed economy model to study the interactions among sovereign risk premia, fiscal limits, and fiscal policy. The fiscal limits, which measure the government's ability to service its debt, arise endogenously from dynamic Laffer curves. The state-dependent distributions of fiscal limits depend on the growth of lump-sum transfers, the size of the government, the degree of countercyclical policy responses, and economic diversity. The country-specific fiscal limits imply that the market perceives the riskiness of sovereign debt issued by different countries to be different, which is consistent with the observation that developed countries are downgraded at different levels of debt. A nonlinear relationship between sovereign risk premia and the level of government debt emerges in equilibrium, which is in line with the empirical evidence that once risk premia begin to rise, they do so rapidly. Nonlinear simulations show that fiscal austerity measures that aim to balance the government budget in the short run fail to contain the default risk premium, even with sizeable cuts in government purchases; but a long-term plan for fiscal reform, if it credibly changes the market's expectation about future fiscal policies, can alleviate the rising risk premium.  相似文献

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.  相似文献

This paper analyses a small open economy that wants to borrow from abroad, cannot commit to repay debt but faces costs if it decides to default. The model generates analytical expressions for the impact of shocks on the incentive compatible level of debt. Debt reduction generated by severe output shocks is no more than a couple of percentage points. In contrast, shocks to world interest rates can substantially affect the incentive compatible level of debt.  相似文献

In this paper we investigate the interdependence of the sovereign default risk and banking system fragility in two major emerging markets, China and Russia, using credit default swaps as a proxy for default risk. Both countries’ banking industries have strong ties with their governments and public sector, even after a series of significant reforms in the last two decades. Our analysis is built on the case studies of each country’s two biggest banks. We employ a bivariate vector autoregressive (VAR) and vector error correction (VECM) framework to analyse the short- and long-run dynamics of the chosen CDS prices. We use Granger causality to describe the direction of the discovered dynamics. We find evidence of a stable long-run relationship between sovereign and bank CDS spreads in the chosen time period. The more stable relationship is found in cases where the biggest state-owned universal banks in emerging markets are closely managed by the government. But the fragility of those banks does not directly affect the state of public finances. However, in cases where state-owned banks directly participate in large governmental projects, banking fragility may result in the deterioration of state funds, while raising the risk of sovereign default.  相似文献

This paper investigates the dependence structure between default risk premium, equity return volatility and jump risk in the equity market before and during the subprime crisis. Using iTraxx CDS index spreads from Japanese and Australian markets, the paper models the different relationships that can exist in different ranges of behavior. We consider several Archimedean copula models with different tail dependence structures, namely, Gumbel, Clayton, Frank, AMH and Joe copulas. Although the dramatic change in the levels of the iTraxx CDS index, we find strong evidence that the dependence structure between CDS and stock market conditions is asymmetric and orienting toward the upper side. In addition, we find that the Japanese CDS market is more sensitive to the stock return volatility than the jump risk and the magnitude of this sensitivity is related to the market circumstances. However, Australian CDS market is more sensitive to the jump risk than stock return volatility before and during the financial crisis. This result has important implications for both global financial stability and default risk management. Specifically, the heterogeneity of markets, coupled with the diversity in the risk exposures cause the default risk premium and equity markets to exhibit different levels of sensitivity.  相似文献

This paper extends the AK production model in Pindyck and Wang (2013) into a more general setting in which the volatility of capital stock is stochastic and driven by shocks. After solving the equilibrium, the fundamental shocks are embedded into the stock price and the leverage effect is contributed from three distinct channels. As an application, we employ our extended AK production model to match well the negative variance risk premium.  相似文献

The euro area sovereign debt crisis has renewed interest in government credibility and the risk of default. Recent empirical evidence has shown that the sharp increase in government bond yields cannot be attributed entirely to changes in macroeconomic fundamentals. Contagion effects can occur, and self-fulfilling speculation may arise. In this paper, we develop a theoretical model in the spirit of the second-generation currency crisis models developed by Obstfled (1996). The model describes a strategic game between governments and private investors. Euro area countries face a trade-off as governments may either commit to and implement restrictive fiscal policies or default on debt. The commitment strategy may not be optimal if the fundamentals deteriorate. The policy maker lose part of their credibility, and governments are forced to default. In addition, we introduce uncertainty about the cost of default in the model, which is then able to account for a greater variety of equilibrium. Thus, when the evaluation of the cost of default is asymmetric, prophecies are not always realized and default does not occur. Simulations of the model then show that it offers insights, and can help to account for the situations of Greece and Italy during the sovereign debt crisis.  相似文献

This article studies the characteristics of a S-based tax system under default risk. In particular we show that its neutrality properties depend on whether debt is protected or unprotected. In the former case, this system is neutral. In the latter case, where default timing is optimally chosen by shareholders, the S-based system is neutral with respect to real decisions only if the firm's and the lender's tax rate are equal. However, the shareholders' decision to default is always distorted.  相似文献

In this article, we have used a continuous EBIT-based model to study deferred tax liabilities under default risk. Quite surprisingly, default risk has been disregarded in research on deferred taxation. In order to underline its importance, we first calculated the probability of default, over a given time period, together with the contingent value of tax deferral. We then applied our theoretical model to a sample of 27,749 OECD companies. We showed that, when accounting for both firms with a negative EBIT and firms with a probability of default higher than 50% (over a 10-year period), a relevant percentage of firms were close enough to default. Hence, the expected present value of deferred taxes is much lower than that obtained in a deterministic context. From the Government’s point of view, deferred tax liabilities are a risk-free loan. Since only a portion are subsequently repaid, the Government should account for future losses due to companies’ default. So far, these estimates have been missing, although techniques do exist and are quite practical.  相似文献

Conclusion The relationship between uncertainty and the optimal savings-consumption decision has been discussed. A simple model has been used to show that the existence of default risk has potentially important effects on the nature of this relationship and should not be neglected in its analysis.  相似文献

Using a disaggregate survey database, this paper reexamines the issue of the existence of a time-varying risk premia in three foreign exchange markets. Previous research on this topic has utilised a consensus measure of the risk premium, based on the rational expectations assumption, and is not supportive of the existence of such a premium. In contrast, this paper reports compelling evidence in favour of time-varying risk premia for the British pound (BP), German mark (DM), and Japanese yen (JY) exchange rates. In particular, we demonstrate that consensus measures of the risk premium mask the existence of risk because of the importance of heterogeneous expectations.  相似文献

The aim of this work is to measure the risk-price sensitivity to interest rate changes in the Spanish market and to see if sensitivity is lower with public debt. To contrast this hypothesis, this study presents a model that analyzes the sensitivity of the risky prices before variations in interest rates through duration and convexity, with the purpose of explaining the price of risky bonds. The main advantages of the analysis are the possibility to determine the sensibility of the risky prices before variations of risk-free interest rates in the Spanish market and the construction of a conditional volatility model that overcomes the linearity models of constant variance.  相似文献

The foreign exchange market has become a major arena for investment activity for both corporate and individual investors. Intensive and widespread international investment activity makes the empirical estimation of exchange risk a very topical subject. In this connection, the classic controversy between Hicks and Telser assumes new relevance. In this paper, exchange risk is estimated in the context of the systematic-risk framework. The estimation is performed for three major floating currencies: the English pound, the Swiss franc, and the Deutsche mark, over a four-year period. The results suggest that although the total risk (measured by the variance) is high, the systematic risk is close to zero. This result provides an explanation for the apparent inconsistency between the Hicks-Keynes hypothesis which indicates the existence of a positive risk premium in the forward exchange market and the empirical evidence of a zero risk premium.  相似文献

The empirical results of the risk-return relationship are mixed for both mature and merging markets. In this paper, we develop a new volatility model to revisit the risk-return relation of the aggregate stock market index by extending the Realized GARCH model of Hansen et al. (2012) with the Wang and Yang (2013) framework, in which the overall risk-return relation is decomposed into a risk premium and a volatility feedback effect. An empirical analysis of three major Chinese stock indices reveals positive risk premium and negative volatility feedback effect, and those findings are stable across different markets and sub-samples. However, their relative magnitudes differ between markets and varies through time.  相似文献

This paper shows that state-uncertainty preferences help to explain the observed exchange rate risk premium. In the framework of Lucas (1982) economy, state-uncertainty preferences amount to assuming that a given level of consumption will yield a higher level of utility the lower is the level of uncertainty perceived by consumers. Under these preferences we can distinguish between two factors driving the exchange rate risk premium: “macroeconomic risk” and “the risk associated with variation in the private agents' perception on the level of uncertainty”. Empirical evidence from three main European economies in the transition period to the euro provides empirical support for the model. The model is more successful in accounting for the observed currency risk premium than models with more standard preferences, and the general perception of risk by private agents is shown to be a more important determinant of risk premium than macroeconomic uncertainty.  相似文献
