Interrelated Factor Demands and Technological Change: An Empirical Assessment of Adjustment for Sectors of the Dutch Economy

Using a translog cost functional form, a formal operational model with an adjustment process according to a first-order autoregressive scheme is presented, that allows the simultaneous determination of factor demands and of technological change in an input–output system. The analysis is carried out for sectors of the Dutch economy over the period 1954–83 and it reveals evidence of the dependence of factor demands on relative prices and on technological change.     

Decomposition of Technological Change and Factor Bias in Indian Power Sector: An Unbalanced Panel Data Approach

Technological change and factor bias in the Indian power sector are analyzed using a translog cost function. Various components of technological progress and factor bias are identified and estimated, using a 21 year unbalanced panel data of Indian states and union territories. Heterogeneity across states is incorporated in the model using a variance component model. Appropriate corrections are made for unbalanced panel data. Empirical results show that the annual average rate of technological progress has been 2.4% for the country as a whole. Accumulation of knowledge and increasing scale are found to be the major factors contributing to technological progress. In contrast, the effects of factor price changes and fixed capital accumulation on technological progress have been unfavorable. Pure factor bias measure indicate saving in the use of fuel and labor, and increased use of materials. Tests are performed to check the curvature properties of the underlying technology.     

企业商业模式在宏观政策变动下的演化分析——基于房地产上市公司的实证研究

商业模式是指企业中企业战略、组织结构、交易过程、价值链和核心竞争力等一系列要素的整合。它反映了企业创造、获取和传递价值的基本原理。在回顾商业模式相关研究基础上,采用中国房地产上市公司2002-2010年的数据,对商业模式中的成本结构和收入来源结构进行了实证分析。结果显示房地产公司成本结构2007年与2004年相比、2009年与2007年相比均发生了显著变化,收入来源结构2008年之后变化速度明显加快。在此基础上,探讨了房地产宏观调控政策与房地产公司商业模式演化之间的关系,并对房地产公司的商业模式的调整提出了建议。
