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.     

天然气操作成本影响因素分析方法研究

以HTB气田为例,首先采用帕累托原理和灰关联分析,找出气田操作成本中的主要影响因素和各分项费用与操作成本之间的关联度,再采用指数分析法精确地描述其变动的影响因素,从而全面、准确分析天然气操作成本变动情况,为天然气成本控制和提高气田的经济效益提供科学依据。

我国西部地区经济发展效率评价研究——以新疆天山北坡经济带为例

以西部大开发中具有重要战略地位的新疆为例,选取新疆经济发展的核心区域——天山北坡经济带2009²010年23个县市的数据,分别从静态和动态视角运用BCC模型和Malmquist全要素指数评价天山北坡经济带各县市20092010年23个县市的数据,分别从静态和动态视角运用BCC模型和Malmquist全要素指数评价天山北坡经济带各县市2009²010年的经济发展效率和全要素生产率的变化情况。分析结果表明:2009年天山北坡经济带有13个县市经济发展非DEA有效,2010年情况有所好转但仍有11个县市非DEA有效,存在发展效率低下、资源配置不合理和资源浪费等问题。总体来看,由于技术效率无效、技术进步贡献不足等原因,天山北坡经济带的Malmquist全要素生产率还很小,全要素改善的来源主要是技术进步,技术效率对TFP有消极拖累作用。     

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.
