Physical capital taxation and labor income taxation in an endogenous growth model with new generations

This paper examines the growth and welfare effects of physical capital taxation and labor income taxation. It is found that the impact of a rise in the physical capital tax rate on the balanced growth rate is crucially related to the birth rate, but a rise in the labor income tax rate definitely reduces the balanced growth rate regardless of the birth rate. It is also found that an increase in the physical capital income tax rate will harm the older but will benefit the younger, while an increase in the labor income tax rate will benefit the older but will harm the younger.

辩证法与实践理性

长期以来,人们习惯于在"理论理性"的层面上理解辩证法的本性、主题与功能.自康德以来,这种意义上的辩证法遭遇到严峻挑战.从实践理性的层面重新阐释辩证法,巳成为深化辩证法研究所面临的重大任务.立足于现代社会生活实践,个人"主观性视角的有限性"与社会生活"他人视角的无限性,,之间所存在的矛盾,为辩证法克服理论理性层面辩证法的抽象性和虚幻性,实现从理论理性向实践理性的转向提供了重要的生长点和问题意识,在承认"理性多元论事实"的前提下,通过"对话"、"宽容"与"相互承认",来寻求这一矛盾的克服,实现社会的团结与社会的统一性.这构成了作为实践理性的辩证法的核心内容.     

Confidence intervals for survival quantiles in the Cox regression model

Median survival times and their associated confidence intervals are often used to summarize the survival outcome of a group of patients in clinical trials with failure-time endpoints. Although there is an extensive literature on this topic for the case in which the patients come from a homogeneous population, few papers have dealt with the case in which covariates are present as in the proportional hazards model. In this paper we propose a new approach to this problem and demonstrate its advantages over existing methods, not only for the proportional hazards model but also for the widely studied cases where covariates are absent and where there is no censoring. As an illustration, we apply it to the Stanford Heart Transplant data. Asymptotic theory and simulation studies show that the proposed method indeed yields confidence intervals and bands with accurate coverage errors.     

Micro-Macro Interactions in Ethno-Religious Homogamy among Hui Muslims in Contemporary China: The Roles of Residential Concentration and Aging

Chinese Muslims have actively maintained religious endogamy. However, no research has assessed the role of local residential context in individual Muslims’ marital choices, nor have sociologists examined the heterogeneity in individual Muslims’ responses to such contextual influences. Using Chinese census data between 2000 and 2005, this paper offers a first investigation of such micro–macro interactions among the Hui, the largest Muslim ethnic group in China. Specifically, we test the effect of the Hui's residential concentration (at the prefecture level) on individual Hui's marital choices (exogamy/endogamy/singleness) and how this effect varies by gender and age. Several major findings emerge from our multilevel discrete-time competing-risk models, highlighting the impact of contextual factors, but also a level of individual resilience against aggregate-level cultural forces. While at younger ages, Hui can still afford to wait to contract an endogamous marriage; with aging, they started to choose exogamy to fulfill the expectation of universal marriage.     

论“道德的政治”——儒家政治哲学的特质

"道之以德"和"为政以德"是孔子对古代"政以治民"和"政以正民"的重大改造.古代儒家强调政治德行对于政治过程的重要性,认为政治的本质就是道德教化,坚持以美德为政治的基础,以善为政治的目的,以仁贯通于政治的实践.这些思想在现代社会的政治制度条件下,仍然有其不可忽略的意义,当代东亚政治的权力腐化现象也证明了这一点.     

Logistic regression analysis of non‐randomized response data collected by the parallel model in sensitive surveys

To study the relationship between a sensitive binary response variable and a set of non‐sensitive covariates, this paper develops a hidden logistic regression to analyse non‐randomized response data collected via the parallel model originally proposed by Tian (2014). This is the first paper to employ the logistic regression analysis in the field of non‐randomized response techniques. Both the Newton–Raphson algorithm and a monotone quadratic lower bound algorithm are developed to derive the maximum likelihood estimates of the parameters of interest. In particular, the proposed logistic parallel model can be used to study the association between a sensitive binary variable and another non‐sensitive binary variable via the measure of odds ratio. Simulations are performed and a study on people's sexual practice data in the United States is used to illustrate the proposed methods.     

Responsive supply chain: A competitive strategy in a networked economy

Supply chain management (SCM) has been considered as the most popular operations strategy for improving organizational competitiveness in the twenty-first century. In the early 1990s, agile manufacturing (AM) gained momentum and received due attention from both researchers and practitioners. In the mid-1990s, SCM began to attract interest. Both AM and SCM appear to differ in philosophical emphasis, but each complements the other in objectives for improving organizational competitiveness. For example, AM relies more on strategic alliances/partnerships (virtual enterprise environment) to achieve speed and flexibility. But the issues of cost and the integration of suppliers and customers have not been given due consideration in AM. By contrast, cost is given a great deal of attention in SCM, which focuses on the integration of suppliers and customers to achieve an integrated value chain with the help of information technologies and systems. Considering the significance of both AM and SCM for firms to improve their performance, an attempt has been made in this paper to analyze both AM and SCM with the objective of developing a framework for responsive supply chain (RSC). We compare their characteristics and objectives, review the selected literature, and analyze some case experiences on AM and SCM, and develop an integrated framework for a RSC. The proposed framework can be employed as a competitive strategy in a networked economy in which customized products/services are produced with virtual organizations and exchanged using e-commerce.     

“金砖国家”经贸合作面临的机遇和挑战

为了克服传统的基于显性比较优势指数的非对称性缺陷,本文基于对称性显性比较优势指数构建了对称性相对贸易优势指数,根据该指数确定了金砖国家各自的优势产业和劣势产业,进而确定金砖国家相互间具有高贸易增长潜力的行业。为了进一步准确地衡量金砖国家间的贸易竞争和互补状况,本文基于对称性显性比较优势指数构建了“对称性贸易互补性指数”和“对称性贸易竞争性指数”,利用这两个指数从细分的产业层面研究确定了金砖国家内部任意两国之间竞争（或互补）的广度和深度。最后根据实证研究结论提出了深化金砖国家合作的对策建议。
