In this article we analyze the slope of the term structure of credit spreads. We investigate the explanatory role of interest rate, market, and idiosyncratic equity variables that the recent empirical literature highlights as important determinants of credit spread levels. This study extends the analysis and assesses its effect on credit slopes for a sample of corporate bonds. We find that these factors affect credit spreads at short and long maturities in a significantly different way. A closer inspection of the credit spread slope also reveals that it is a useful indicator of the direction of changes in future short‐term credit spreads. This evidence has important implications for the trading and risk management of portfolios of bonds with different maturities. 相似文献

The managerial-discretion hypothesis states that in mutual insurance companies policyholders will seek to protect their interests by limiting managerial discretion in investment and financing decisions. Therefore, mutuals are predicted to introduce restrictive mechanisms (e.g., company by-laws) that promote precautionary investment, such as government securities. In stock companies, shareholders are expected to increase their wealth at the expense of policyholders' interests by investing in more speculative assets, such as equities. Differences in investment activity also affect policy valuation and reserving decisions reflected in the liability side of the insurance company balance sheet. The managerial-discretion hypothesis implies that systematic differences in the structure of balance sheets between mutual and stock insurance companies are likely to exist. To carry out an exploratory test of this aspect of the managerial-discretion hypothesis, the present study employs canonical correlation analysis on New Zealand life insurance company data for 1991. However, the empirical evidence does not appear to support the proposition that balance sheet structure varies systematically between mutual and stock companies. 相似文献

Using a general autoregressive distributed lag model, we estimate the longrun steady state determinants of corporate capital structure. We find that, in the long run, the leverage ratio is related positively to the corporate tax rate and firm size and negatively to future growth opportunities and stock returns. By contrast, there appears to be no relation between leverage and the corporate tax rate on a short-run year to year basis. Our results suggest that prior empirical evidence on capital structure is of questionable value precisely because of its failure to clearly separate the short-run relationship between leverage and its determinants from its long-run relationship. 相似文献

利率期限结构理论在我国证券市场的实证分析 总被引:1,自引:0,他引:1
本文利用利率期限结构理论,通过对中国证券市场的实证研究,分析我国的利率传导机制和其运行效率。利率期限结构事实上承担着整个社会资源配置的参照系,其可以引导存贷款利率以及中央银行存款准备金利率的变动,形成一条科学合理的收益率曲线。目前中央银行主要通过公开市场操作来影响货币市场利率。作者使用当前金融市场的资料验证不同期限利率水平之间存在一种长期均衡关系,我国收益率曲线的变动基本上是服从流动性偏好理论;同时,随着市场的发展,各类证券收益率之间的传导机制也在不断的完善。因此,中央银行对利率的市场化引导和调控机制已经初步具备,但该机制还有待于进一步的完善。 相似文献

THE STRUCTURE OF SKEWNESS PREFERENCES IN ASSET PRICING MODELS WITH HIGHER MOMENTS: AN EMPIRICAL TEST
In this paper, the authors employ a nonlinear formulation to examine empirically the structural content of the three moment capital asset pricing model (CAPM). Whereas previous research focused on the coefficients of beta and co-skewness, this paper presents empirical results on the market risk premium and elasticity coefficient components of these two coefficients. The results indicate that although the estimated coefficient of coskewness gives important information on the marginal rate of substitution between skewness and expected return, the elasticity coefficient can provide additional (albeit different) information on skewness preference that is independent of the effects of the market risk premium. This research also shows how the non-linear formulation provides a direct linkage between the twomoment and three-moment CAPM versions and thus provides an empirical test of the theoretical conditions under which skewness preference is consistent with the two-moment CAPM empiricial results. 相似文献

The objective of this paper is to estimate and test multifactor versions of the Cox-Ingersoll-Ross (CIR) model of the nominal term structure of interest rates. The proposed state-space approach integrates time series and cross-sectional aspects of the CIR model, is consistent with the underlying economic model, and can use information from all available points of the term structure. We recover estimates of the underlying factors that are consistent with the assumptions about the stochastic processes and compare them with factors obtained from standard factor analysis. We perform thorough diagnostic checking and thereby provide new evidence regarding conclusions about the adequacy of the CIR model. We present empirical results for U.S. Treasury market data. Although the specification of multifactor CIR models is sufficiently flexible for the shape of the term structure, we find strong evidence against the adequacy of the CIR model. 相似文献

In this paper I examine the term structure of Eurocurrency interest rates from six countries (with maturities of one, two, three, and six months) using unit root tests and cointegration tests that are robust to departures from independent and identically distributed errors. The main conclusions are: (1) Eurocurrency interest rates have one (and only one) unit root when viewed individually, and (2) for each of the countries examined, Eurocurrency interest rates are cointegrated—with one equilibrium relationship—when viewed jointly. These conclusions are consistent with the weak form of the efficient market hypothesis and suggest that in efficient markets arbitrage generally prevents rates on different maturities of a given asset from drifting too far for an extended period. 相似文献

The nature of the stochastic process generating the path of security prices through time plays an important role in dynamic theories of financial economics. An important consideration is the possible dependency of return variances on price levels. Using 55 years of data separated into five-year intervals, this study demonstrates that, in general, security and portfolio variances are dependent on stock price levels and the relationship is a function of portfolio size. The relationship is unstable over time. The results suggest possible detrimental effects of diversification and financial models based on log-normality are questionable. 相似文献

The purpose of this paper is to determine why net income adjusted for depreciation and amortization (NOF) is a strong predictor of financial distress. This paper develops four-state ordinal financial distress models lagged one, two, and three years before financial distress to test NOF, instead of using dichotomous bankrupt and nonbankrupt models. The results of this paper suggest that NOF is a strong predictor of financial distress because NOF is an alternative measure of economic income, not because NOF is a naive measure of operating cash flow. For this study, NOF is even a better measure of economic income than net income. 相似文献

This paper applies the rationality concept and expectations hypothesis to test the information efficiency of the term structure of the New Zealand bank bill market. Weekly data is collected from June 1986 to November 1988. The sample period is partitioned into two subperiods by the sharemarket crash in October 1987. The empirical results suggest the presence of a time varying risk premium. This is reflected by the significantly positive volatility measure in the first subperiod and the significant interest rate level variable in both subperiods. The forecast errors correlate significantly with the growth in money supply and overseas interest rate variables. Factors other than market information inefficiency could be responsible for the significant correlation; namely the impact of the sharemarket crash on market perceptions about inflation expectations and the non-simultaneous data problem in calculating the differential costs of borrowing. Despite the rejection of the joint hypothesis, forward rates are found to have information about future spot rates beyond that contained in past spot rates, and are able to predict interest rates at least 30 days ahead. 相似文献

Consistent with theoretical predictions, we find that both a higher level of financial leverage and a faster speed of adjustment of leverage toward the shareholders' desired level are associated with better corporate governance quality as defined by a more independent board featuring CEO–chairman separation and greater presence of outside directors, coupled with larger institutional shareholding. In contrast, managerial incentive compensation on average discourages use of debt or adjustments toward the shareholders' desired level, consistent with its entrenchment effect. The effect of corporate governance on leverage adjustments is most pronounced when initial leverage is between the manager's desired level and the shareholders' desired level where the interests of managers and shareholders conflict. 相似文献
