Following the approach of interpolation, this paper proposes the multiple exponential decay model to fit yield curves for both the U.S. TIPS market and the conventional Treasury security market. Several estimation methods, including the unconstrained/constrained nonlinear minimization, quadratic programming, and the iterative linear least squares, are applied to estimate the unknown parameters according to different curve‐fitting purposes. Comparisons between the proposed model and the alternatives show that the multiple exponential decay successfully (1) adapts to a variety of shapes associated with yield curves, (2) (partially) keeps in line with the economic interpretations of Nelson–Siegel summarized by Diebold and Li ( 2006 ), and (3) dominates the competing models in curve‐fitting performance measured by mean fitted‐price errors over the sample period. In addition, the exact specification of a nonparametric interpolation model is pinned down by applying three statistical tools, which enable us to jointly take into account validity, optimality, and parsimoniousness of the proposed model.  相似文献

Three major, interrelated accounting statements, at the frontiers of quantitative economic analysis, are three interrelated systems, namely: (1) National income and product accounts (NIPA), (2) The input-output tableaux, (IO), and (3) flow-of- funds accounts (FF). The third-mentioned system is somewhat less available and used in only limited areas of macroeconomic analysis. This paper is mainly concerned with use of FF accounting systems. This system shows where financial resources originate, and where they go in support of real capital formation. In this respect, interest rates and other market-based financial rates are of key importance. While much macroeconomic analysis is based on the rates that fit the yield curve, showing the interest rate structure over various maturities of debt associated with a given degree of risk. In contrast, the FF accounts throw light on the whole spectrum of interest rates, across maturities and debt qualities. For example, in analysis of the real estate market and funding of capital formation there, it is important to have a full understanding of the course of mortgage rates of different maturities and qualities. In short, it is necessary to develop a full appreciation of supply and demand forces in the mortgage market, which often is not obviously related to movements of the operative rate for monetary policy, such as very short-term inter bank rates or call money rates. This paper attempts to provide material from the flow-of-funds accounts that would make it possible to analyze the movement of relevant mortgage rates or whatever other rates are needed to understand the financing of capital formation in real estate.  相似文献

We examine momentum and contrarian effects in China's stock market during 1994-2004 and find that no medium momentum effects exist. Meanwhile, contrarian strategy works effectively over the horizon of 18-36 months. 1-month gap for avoiding bid-ask bounce and lead-lag effect make no considerable change to our empirical results. Transaction costs seem to have no significant impact on contrarian strategies' profit.  相似文献

This paper investigates the existence of a correction mechanism for mis-pricing between Japanese stock and bond. By this correction mechanism we mean that when deviations occur from the equilibrium levels of the expected return differentials between stock and bond — the risk premium differentials, the market will tend to correct the mis-pricing and bring the expected return differentials back to the equilibrium levels. We assume that the yield spread between the predicted earnings price ratio of stock and the yield to maturity of bond reflects the risk premium between stock and bond, and estimate the equilibrium risk premium differentials and mis-prices between stock and bond by modelling their behaviors with a statistical yield spread model (SYS). Empirical results strongly indicate the existence of the mis-pricing correction mechanism, suggesting the inefficiency of securities markets.  相似文献

Abstract:  This study finds evidence of significant long-term underperformance following rights issues made during 1986-95 in the UK. The findings are resilient to a number of methodological controls. In contrast, our results for a smaller sample of open offers made during 1991-95 show strong positive performance over a 5-year post-issue period, implying that firms making open offers had better growth prospects than firms making rights issues. During 1986-90, a period when open offers were rarely used, firms appeared to be making rights issues to exploit overvaluation. However, this was not evident for rights issues made during 1991-95, a period when open offers were more commonly used.  相似文献

Modeling Conditional Yield Densities   总被引:2,自引:0,他引:2  
Given the increasing interest in agricultural risk, many have sought improved methods to characterize conditional crop-yield densities. While most have postulated the Beta as a flexible alternative to the Normal, others have chosen nonparametric methods. Unfortunately, yield data tends not to be sufficiently abundant to invalidate many reasonable parametric models. This is problematic because conclusions from economic analyses, which require estimated conditional yield densities, tend not to be invariant to the modeling assumption. We propose a semiparametric estimator that, because of its theoretical properties and our simulation results, enables one to empirically proceed with a higher degree of confidence.  相似文献

随着时代发展,独居、年轻化已成为租房人群的关键词。观念的升级和住房租赁政策的完善,使得90后的置业观悄然改变。经过市场调查,市面上还没有针对大学毕业生这一群体的长租公寓,多数是针对有一定经济能力的上班族。因此,大学毕业生的住房需求仅仅通过政府采取措施远远无法满足。论文从国家的宏观政策及市场微观细分因素中的人口因素、地理因素、行为因素等方面对“不期而寓”——青年城市配套综合体进行了分析,为项目的推进提供可靠的数据和科学性支持。  相似文献

传统的久期理论建立在收益曲线平移等严格假设条件上,因而其在实践中的有效性大大降低了。根据Markowitz(1959)等理论可推导出:资产价格的总风险包括收益的方差和全久期向量两部分;假若商业银行采取现金中性(cash neutrality)的资产交易策略,风险计量模型可转换为线性规划问题,从而可以构建基于利率风险最小化模型的随机免疫策略。也就是说,引入随机免疫的理念来替代经典的免疫理论,通过实证分析得出:无现金交易条件下的随机免疫策略能够降低利率风险。  相似文献
