Towards Uniformly Efficient Trend Estimation Under Weak/Strong Correlation and Non‐stationary Volatility

In this paper, we consider the deterministic trend model where the error process is allowed to be weakly or strongly correlated and subject to non‐stationary volatility. Extant estimators of the trend coefficient are analysed. We find that under heteroskedasticity, the Cochrane–Orcutt‐type estimator (with some initial condition) could be less efficient than Ordinary Least Squares (OLS) when the process is highly persistent, whereas it is asymptotically equivalent to OLS when the process is less persistent. An efficient non‐parametrically weighted Cochrane–Orcutt‐type estimator is then proposed. The efficiency is uniform over weak or strong serial correlation and non‐stationary volatility of unknown form. The feasible estimator relies on non‐parametric estimation of the volatility function, and the asymptotic theory is provided. We use the data‐dependent smoothing bandwidth that can automatically adjust for the strength of non‐stationarity in volatilities. The implementation does not require pretesting persistence of the process or specification of non‐stationary volatility. Finite‐sample evaluation via simulations and an empirical application demonstrates the good performance of proposed estimators.     

民国新儒家的墨学观

民国新儒家的墨学观比较复杂，深刻地打上了西学东渐的时代烙印，与传统儒家大异其趣。民国新儒家主要从西方科技、逻辑学、实验主义理论的角度，将墨学看作中国文化中最具西方文化色彩的部分，因此，他们一方面认为墨不如儒，认为墨学的缺陷与西方文化相同，从而对墨学进行了一系列的批评，另一方面也像肯定西方文化那样，认为墨学有一定价值，主张以儒为主融墨。另外，民国新儒家也能够在一定程度上摆脱西方文化的笼罩，对墨子的伟大人格和救世牺牲精神进行高度评价。     

Constrained vs unconstrained labor supply: the economics of dual job holding

This paper develops a unified model of dual and unitary job holding based on a Stone-Geary utility function. The model incorporates both constrained and unconstrained labor supply. Panel data methods are adapted to accommodate unobserved heterogeneity and multinomial selection into six mutually exclusive labor supply regimes. We estimate the wage and income elasticities arising from selection and unobserved heterogeneity as well as from the Stone-Geary Slutsky equations. The labor supply model is estimated with data from the British Household Panel Survey 1991–2008. Among dual job holders, our study finds that the Stone-Geary income and wage elasticities are much larger for labor supply to the second job compared with the main job. When the effects of selection and unobserved heterogeneity are taken account of, the magnitudes of these elasticities on the second job tend to be significantly reduced.     

时刻莫忘珍惜土地

土地,被卡尔·马克思称之为"一切生产和一切存在的源泉".也就是人们通常所说,土地是人类赖以生存的物质基础,是不可再生的宝贵资源和重要资产,是人类一切活动和社会经济发展的载体.

阜新经济转型发展方向研究

在分析总结法国洛林和德国鲁尔等地区煤炭产业转型的成功经验基础上,对阜新与国外煤炭产区的经济转型进行了宏观对比分析,并根据阜新实际,对经济转型的接续产业和劳动力转移途径进行了研究探讨。在此基础上,提出了阜新经济转型重点应向现代农业和现代服务业转移,调整优化第二产业,并就经济转型中的劳动力就业、转型资金筹集和环境保护等问题提出了政策和措施建议。     

诗词诗意意义的解释、构成与对诗词的完整把握

诗词意义可区分为词典意义的陈述和解释与诗意意义的解释与描述。论述诗词的诗意意义的构成方式 ,指出诗意意义的解释和描述比词典意义的陈述和解释更接近于对诗词本身的把握 ,但这种接近对古典诗词的把握来说 ,还隔着两层 ,即文字文本诗意经验层和声音文本诗意经验层。     

从译者的审美意识谈文学作品中非规范语音的翻译

文学翻译特别需要译者的审美意识 ,需要作为审美主体的译者发挥创造性和主观能动性。翻译的过程就是原文的审美再现过程。文学作品的翻译要忠实地译出人物的语言特色 ,再现原文的生动形象。语言的常规优美固然重要 ,但正如残缺美也是美一样 ,在文学作品中 ,人物的非规范语言也是一种美 ,因为它有助于烘托生动活泼的人物形象。因此 ,在翻译中要忠实再现 ,否则会影响译文的准确性、生动性     

民间说书与中国古代通俗小说的传播

中国古代的通俗小说主要是通过民间说书等艺术形式扩大其在民间的广泛影响的。民间艺人不仅多以通俗小说作为取材或演说的对象,而且对之进行了多方面的艺术加工,这才使通俗小说更加通俗易懂,更为民众所喜闻乐道。
