中美高收益债券市场发展比较研究

在美国市场上,高收益债已经发展成为一种相对独立的资产类别,而中国的高收益债市场才刚刚起步,对其研究也相对匮乏。本文在厘清中国高收益债的定义前提下,以美国成熟市场为参照,对中国当前时间截面上高收益债市场的存量分布和分类做出详细描述,并展示了中国高收益债的风险收益特征与成熟市场的异同。研究认为,由于中美高收益债市场发展阶段差异显著,投资者亟需寻找不同的投资逻辑和策略。     

Game-theoretic modeling of pre-disaster relocation

Abstract

Sea-level rise due to climate change is clearly an important problem. This paper uses game theory in conjunction with discounting to explore strategies by which governments might encourage pre-disaster relocation by residents living in areas at high risk of flooding due to sea-level rise. We find that offering a subsidy (e.g., a partial buyout) can be effective if government has a significantly lower discount rate than residents. We also present extensions to our model, exploring the use of a fixed annual benefit after relocation (instead of a one-time subsidy), and hyperbolic instead of standard exponential discounting. Numerical sensitivity analysis elucidates many important factors affecting the timing of anticipatory relocation, since for example relocating too soon may be costly to both residents and government if flooding risk is increasing only gradually. This conceptual model also provides a foundation for future studies that quantify the model with more realistic parameter values (e.g., realistic estimates of flooding probabilities), and alternative behavioral models of resident decision making.     

瑞替普酶治疗急性心肌梗死患者的临床疗效

目的探讨瑞替普酶治疗急性心肌梗死患者的临床疗效。方法收集2013年1月至2014年2月收治的66例急性心肌梗死患者资料,按患者入院治疗时间顺序分为两组,对照组33例患者予以尿激酶治疗,瑞替普酶组33例患者予以瑞替普酶治疗。比较两组患者溶栓后临床再通率、病死率以及并发出血率。结果瑞替普酶组患者临床再通率明显高于对照组(P<0.05);且该组患者并发出血率、病死率均明显低于对照组(均P<0.05)。结论采用瑞替普酶治疗急性心肌梗死具有较高理想的临床治疗效果,且安全性高。

Detections of changes in return by a wavelet smoother with conditional heteroscedastic volatility

In this paper, we propose two estimators, an integral estimator and a discretized estimator, for the wavelet coefficient of regression functions in nonparametric regression models with heteroscedastic variance. These estimators can be used to test the jumps of the regression function. The model allows for lagged-dependent variables and other mixing regressors. The asymptotic distributions of the statistics are established, and the asymptotic critical values are analytically obtained from the asymptotic distribution. We also use the test to determine consistent estimators for the locations of change points. The jump sizes and locations of change points can be consistently estimated using wavelet coefficients, and the convergency rates of these estimators are derived. We perform some Monte Carlo simulations to check the powers and sizes of the test statistics. Finally, we give practical examples in finance and economics to detect changes in stock returns and short-term interest rates using the empirical wavelet method.
