山东庙岛群岛风尘堆积物研究综述

山东地区风尘沉积类型多样,在中国风尘沉积系统研究中占有重要地位.其中庙岛群岛横跨胶东半岛与辽东半岛之间的渤海海峡,发育了晚新生代以来各个阶段风尘堆积:红色风化壳、棕红土、离石黄土、马兰黄土和全新世黄土.综述了山东庙岛群岛粉尘堆积各沉积层的沉积特征及粒度、矿物组成、磁化率、孢粉等指标目前已取得的研究成果,并对今后研究进行了展望,认为研究重点在于高分辨率年代学和环境代用指标.     

投入产出纳税评估方法的构建

本文首先分析当前我国纳税评估理论和实践中存在的问题,然后以企业投入产出分析为基础探索商品税税基评估思路,以企业产品消耗系数及其与行业消耗系数的偏离数值作为纳税评估指标,并在经修正后的评估指标出现异常条件下给出商品税税基评估值。

Energy Substitution,Separability, and Technical Progress in the Australian Iron and Steel Industry

The effects of the “energy crisis” on the Australian iron and Steel industry are analyzed by using a flexible functional form, the transcendental logarithmic (translog) function, which represents a second-order approximation of any twice differentiable function. The robustness of the translog is analyzed with special attention paid to factor aggregation and separability conditions as they relate to the specification of the functions. The estimation results suggest that capital and energy are substitutes, that aggregation of administrative workers and production labor is inappropriate, and that materials are weakly separable, thereby allowing the estimation of a capital, labor, and energy model. The data set developed covers the financial years from 1946–47 to 1978–79. This 33-year time series allows the use of different temporal subsets. Technical progress is shown to be capital and energy using and labor and material saving. An energy submodel is specified using solid fuels, oil, electricity, and gas; and the interfuel substitutions are estimated.     

Measurement Problems of Inflation Disaggregation

Why do the three quarterly GNP inflation measures differ so much when they are constructed from the same underlying price data? Algebraically and in tables using data of the second quarter of 1984, it is shown that these differences occur because of quarterly shifts in the composition of the nation's product. Disaggregation of the inflation contributions of the GNP components also makes it clear why, for quarterly analyses, the GNP chain price index is superior to both the implicit GNP deflator and the fixed-weight GNP price index. In particular, the implicit GNP deflator can give severely distorted inflation signals.

Scanner Data Price Indexes: Addressing Some Unresolved Issues

Scanner data are increasingly being used in the calculation of price indexes such as the CPI. The preeminent approach is the RYGEKS method (Ivancic, Diewert and Fox 2011 Ivancic, L., Diewert, W.E., and Fox, K.J. (2011), “Scanner Data, Time Aggregation and the Construction of Price Indexes,” Journal of Econometrics, 161, 24–35.[Crossref], [Web of Science ®] , [Google Scholar]). This uses multilateral methods to construct price parities across a rolling year then links these to construct a nonrevisable index. While this approach performs well there remain some unresolved issues, in particular; the optimal window length and the linking method. In this note, these questions are addressed. A novel linking method is proposed along with the use of weighted GEKS as opposed to a fixed window. These approaches are illustrated empirically on a large scanner dataset and perform well.
