In this paper, we empirically examine the systematic risk of corporate bonds in the Euro area. Based on a unique sample of 784 bonds from 1999 to 2010, we show that the systematic risk of constructed bond portfolios and individual bonds—measured against three different market indices—depends on credit quality, term risk, and index choice. A significant increase in systematic risk for lower-rated bonds is observed following the start of the financial crisis. In multi-factor models, bond portfolios load significantly on default and term risk, which are included as additional factors. Conducting Fama and MacBeth cross-sectional tests, we find that default and term risk are priced with economically relevant premiums that range from 0.35 to 0.62 % per month. Our results are robust to the inclusion of characteristics such as rating and time to maturity. 相似文献

This paper develops a two-dimensional structural framework for valuing credit default swaps and corporate bonds in the presence of default contagion. Modelling the values of related firms as correlated geometric Brownian motions with exponential default barriers, analytical formulae are obtained for both credit default swap spreads and corporate bond yields. The credit dependence structure is influenced by both a longer-term correlation structure as well as by the possibility of default contagion. In this way, the model is able to generate a diverse range of shapes for the term structure of credit spreads using realistic values for input parameters. 相似文献

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage operators will pay higher prices for injected gas and earn less on withdrawn gas. Optimal storage operation will take this into account. In this context, considering storage operators as price takers does not account for interdependencies of storage operations and market prices. This paper offers a novel approach to storage valuation taking into account the effect of management decisions on market prices. The methodology proposed within this paper determines the optimal production schedule and value by determining the stochastic differential equation describing the storage value and then applying a finite difference scheme. We find that limited liquidity lowers the storage value and reduces withdrawal and injection amounts. Further, we observe decreasing reservation prices for injection and withdrawing for growing illiquidity resulting in a left shift of injection and withdrawing threshold prices. 相似文献

In the context of the ongoing financial and economic crisis reference is frequently made to the Great Depression of the 1930s
and fears are voiced that we may have embarked on a similar path. This article looks at the conditions prevailing back then
and compares them with the present economic environment. From this some conclusions are drawn as to the likelihood of a recurrence
of the disaster. 相似文献

Political risk represents an important hidden transaction cost that reduces international trade. This paper investigates the claim that public export credit guarantees mitigate this friction to trade flows and hence promote exports. We employ an empirical trade gravity model, where we explicitly control for political risk in the importing country in order to evaluate the effect of export guarantees. Using a novel data set on guarantees, we estimate the effect of guarantees in a static and dynamic panel model. We find a statistically and economically significant positive effect of public export guarantees on exports which indicates that export promotion is indeed effective. Furthermore, political risk turns out to be an important obstacle for exports and hence should be taken into account in any empirical model of trade. 相似文献

Using merged data from the British Household Panel Survey (BHPS) and the German Socio-Economic Panel (SOEP), this paper applies a parametric difference-in-differences approach to assess the real effects of the introduction of the euro on subjective well-being. A complementary nonparametric approach is also used to analyze the impact of difficulties with the new currency on well-being. The results indicate a loss in well-being associated with the introduction of the new currency, with the predicted probability that a person is contented with his/her household income diminishing by 9.7 percentage points. We calculate a compensating income variation of approximately one-third. That is, an increase in post-government household income of more than 30% is needed to compensate for the clear decline in well-being. The reasons for the negative impact are threefold. First, perceived inflation overestimates the real increase in prices resulting in suboptimal consumption decisions. Second, money illusion causes a false assessment of the budget constraint. Third, individuals have to bear the costs from the conversion and the adjustment to the new currency. Moreover, it is thought that losses are higher for persons who have difficulties with the new currency. However, the impact of difficulties in using and converting the new currency is rather small, and the initial problems were overcome within one year of the introduction of euro cash. 相似文献

Home renovation is generally asserted to be a highly effective means to increase residential energy efficiency and thereby contribute to climate protection from reduced energy consumption. As part of a larger package of measures in the residential sector, the German government is consequently providing financial support for home audits from recognized energy experts who provide advice on retrofitting options. To date, the question concerning the effectiveness these home audits has largely escaped empirical scrutiny. The present paper fills this void by providing evidence for considerable free-rider effects within the home audit program, yielding serious reservations with respect to both the effectiveness of the program and its fiscal costs. Moreover, given the substantial differences between the gross- and net effects of home audits that are revealed by this analysis, the program’s contribution to climate protection and thereby the central justification for the associated government outlays is called into question. The social benefit of the program emerges only from those retrofits that would not have been undertaken in the absence of the home audit. 相似文献
