Endogenous technical advance and the stochastic trend in output: A neoclassical approach   总被引：2，自引：0，他引：2  

Gordon Reikard   《Research Policy》2005,34(10):1476-1490

In the recent endogenous growth literature, the trend in output is stochastic, while investment in scientific knowledge is treated as analogous to a capital stock. This paper models both research and development (R&D) and disembodied technical advance using neo-classical equations, which specify the equilibrium stocks as a function of prices and output. The elasticity of R&D in the production function, estimated using factor shares, is time-varying and increasing. Returns to scale are increasing in all factors. The most important aspect of the model is that the equilibrium rate of technical advance is not cyclically invariant, but co-moves with output at business cycle frequencies. This allows the production function to behave as a stochastic trend. Growth accounting demonstrates that long-term variations in the rate of productivity growth have been associated mainly with low-frequency fluctuations in the rate of disembodied technical advance, with secondary effects from the stocks of R&D and physical capital. During the high productivity period 1948–1972, technical advance contributed 1.48 percentage points per year to output, with 0.98 accounted for by R&D. The productivity slowdown of the mid-1970s was accounted by a gradual decline in the effect of R&D, and a more abrupt collapse in disembodied technology. The subsequent productivity revival was associated with two accelerations in disembodied technical advance, the first beginning in the early 1980s, and the second in the mid-1990s. The production function is simulated in a small econometric model. Model simulations find that exogenous shocks to the inflation rate generate significant variations in growth by inducing fluctuations in disembodied technology.  相似文献

Developing a template for National Child Protection Index Reports     

Ager A  Stark L  Chu E  Dewan S  Boothby N 《Child abuse & neglect》2011,35(12):1002-1008

Objectives

What impact does the strengthening of child rights have on the experience and circumstances of children? CRC General Comment 13 emphasizes that defining measurable targets for improvements in child protection is a key element of efforts to strengthen child rights and well-being across the world. This paper describes an attempt to identify key domains relevant to such mapping of child protection indicators, and the feasibility of collecting data—from existing data sources or otherwise—to complete a “National Child Protection Index Report” summarizing achievements and concerns at a national level.

Methods

A process of inter-agency consultation was facilitated by the CPC Learning Network to establish a template for the Index Report. The template was modeled on that used for the “Countdown to 2015” maternal, neonatal and child health initiative, aiming to capture indices not only of key protection risks but also implementation and coverage of key protection measures. The work drew on indicator development and policy initiatives by a number of international child protection agencies. The template developed was used as a basis to pilot national data collection in Indonesia and, at a sub-national level, in northern Uganda.

Findings

The template provides a concise summary of protection issues of relevance to a broad range of constituencies, global and national. However, in the pilot settings, existing routine data collection was inadequate to effectively populate a large proportion of indicators. Mechanisms of collating findings from discrete assessments—another potential source of data for completion of the index report—were also generally underdeveloped.

Practice implications

In settings where state infrastructure allows the collection and analysis of routine data in such domains as health and economic activity, such efforts should be extended to the child protection sector. Discrete assessments by governmental or non-governmental agencies also provide significant potential for more effective sharing and collation of information. National Child Protection sub-clusters or equivalent structures can play an important role in facilitating both of these processes.  相似文献

高职院校电子商务专业教学改革探讨     

胡斌 《科技广场》2011,(12)

从高职院校开设电子商务专业到现在已经有十二余年了,在这十多年的专业发展过程中,无论是开设该专业的高校数量还是选择该专业的学生都在飞速地壮大,应该说电子商务专业的开设为我国高速发展的网络经济提供了大量的技术性人才。但我们同时也发现,目前我国高校开设的电子商务专业无论在办学水平、教学模式,还是在课程设置等方面离社会需求仍有不少的差距,甚至与社会、企业的需求脱节。为了能改变目前在高职院校存在的教学弊端,本文主要从高职院校电子商务专业的教学改革进行研究,尝试研究出适合目前乃至今后社会发展的教学模式。  相似文献

基于技术进步的中国能源消耗与经济增长：前后两个30年的比较   总被引：2，自引：2，他引：0  

魏艳旭  孙根年  李静 《资源科学》2011,33(7):1338-1345

本文依据1953年-2009年统计数据,以单位产值能源消耗为指标,将新中国划分为两个阶段（1953年-1977年和1978年-2009年）,比较了两个阶段能源消耗与经济增长的关系。结果显示：从1953年-1977年,随着人均GDP的升高,人均能源呈同步增长;单位产值能耗从6.76t标准煤增长到17.9t标准煤,能源消耗弹性从3.59下降到-0.58,两者呈现反相关性;从1978年-2009年,随着人均GDP的增大,人均能源消耗波动上升;单位产值能源消耗从17.50t标准煤下降到5.05t标准煤,而能源消耗弹性波动较大。本文依据IPAT方程从广义技术角度对其进行了理论分析,结果表明在前30年经济增长对能源消耗依赖性较大,对技术依赖性较小;而后30年经济增长对能源消耗依赖性减弱,对技术依赖性增强;技术转变与技术进步是引起这种变化的关键因素。  相似文献
