Beyond segmentation: The case of China’s repo markets

This paper explores the reasons behind the discrepancy between interest rates in China’s two repurchase agreement (repo) markets, the interbank repo market and the exchange-traded repo market. The repo rates in the exchange market are at times, significantly higher than those in the interbank market, especially in the first three years of the 2000–2005 sample period. While market segmentation clearly hinders arbitrage, the causes of the repo rate discrepancy are related to the alternative investment opportunities available to market participants and to the volatility differences in the repo rates.

西方就业理论演进的历史轨迹及启示

西方就业理论从18世纪人口与资源均衡发展的思想萌芽开始,到20世纪90年代至今,有古典经济学派人口均衡发展思想、新古典经济学派就业理论、凯恩斯的就业理论、发展经济学的就业理论、人力资本与就业理论、新古典综合派就业理论、新凯恩斯主义就业理论、新自由主义的反古典经济学派就业理论等诸多经济学流派和就业理论体系。各学派深入探讨产生失业的原因,并形成各自颇具特色的就业理论。回顾和梳理西方就业理论的历史演变轨迹,对解决当前中国的就业问题,具有前瞻指导意义和参考价值。     

Diffusion of mobile telephony: An empirical study in Taiwan

Mobile telephony penetration is a major indicator of mobile telephony diffusion. Taiwan had a mobile telephony penetration of 108% in 2002, ranking first in the world. This study analyzes this accelerated diffusion in terms of growth model and determinants of the diffusion rate. To eliminate the inherent uncertainty associated with choosing the optimal growth model, this study compares the performance of three conventional models, namely Gompertz, Logistic and Bass, to identify the most appropriate model, and to distinguish the forces driving the diffusion rate. Empirical results indicate that the most appropriate model is the Logistic model. Network externalities, which this study shows to be the same as the imitation effect in the Bass model, explain the superiority of the Logistic model. Moreover, market competition, which markedly reduces service prices, is identified as a primary driver of the diffusion rate of mobile telephony in Taiwan. Economic conditions, technological innovation and number of operators are insignificant factors. Finally, mobile telephony is a substitute for fixed-line telephony in Taiwan.

HPLC法测定辣椒及其制品中苏丹红色素含量

[目的] 建立辣椒及其制品中4种苏丹红(sudan)色素的高效液相色谱同时测定方法.[方法] 采用反相高效液相色谱法,以乙腈-酸性水溶液为流动相,采用梯度洗脱,以二极管阵列检测器(PDA)定性定量测定辣椒制品中的4种苏丹红色素,并以LC-MS对阳性样品中的苏丹红成分进行了结构确证.[结果] 在添加浓度1～4mg/kg范围内,4种苏丹红色素的回收率在 81.92%～97.87 %之间,相对标准偏差(RSD)≤5.23%,最低检出限(信噪比S/N=3)分别为0.102、0.097、0.074、0.099mg/kg.[结论] 本方法经实际应用证明,具有良好的稳定性和重现性,步骤简单、可操作性强.     

住房抵押贷款提前偿付率的宏观影响因素分析

本文从宏观视角,运用多元线性回归模型和半参数模型等对我国个人住房抵押贷款组合提前偿付率的影响因素及其作用机制进行了实证研究。研究发现货币市场中长期贷款利率的提高,会增加借款人再融资成本,从而降低提前偿付率;资本市场作为借款人的收入来源之一与提前偿付率之间存在正相关关系;家庭人均净收入与提前偿付率的关系是非线性的;此外,与国外研究一致,房价和累计提前偿付额也会影响提前偿付率。
