We propose a Solovian growth model with a convexconcaveproduction function and international technological spillovers.We test the empirical implications of the model, analysing theeffects of the productivity slowdown that followed the oil shocksof the 1970s. We argue that this slowdown, altering the worldincome distribution, affected the pattern of international technologicalspillovers, taking the poorest countries further away from thetechnological leaders, and therefore unable to exploit theirtechnologies. The result is the emergence of a poverty trapfor low-income countries. 相似文献

In this paper, we combine a translog cost functional form with an adjustment process according to the error correction mechanism to explain the simultaneous determination of factor demands and technological change. To save degrees of freedom in the estimation procedure, we also consider the imposition of restrictions on the matrices of lag parameters and/or the covariance matrix of the disturbances. Using a model selection strategy based on a combination of economic-theoretical considerations and a formal model selection criterion, a model is selected for each of 17 sectors of the Dutch economy. It turns out that, for 14 of the 17 sectors under consideration, a model is chosen that allows the imposition of restrictions with respect to the matrices of lag parameters. A comparison of the present results with those obtained by Lesuis and de Boer reveals that the application of more general dynamic structures leads to results that are more in accordance with economic theory. 相似文献

Are Interventions Self Exciting? 总被引:1,自引:0,他引:1
The time pattern of official interventions on the foreign exchange market exhibits periods of intense activity followed by long spells of inaction. In this paper, we examine whether the time interval between successive intervention matters for future interventions. To capture the properties of intervention duration an ACD model is used. The data are daily observations of interventions by the Federal Reserve, the Bundesbank and the Swiss National Bank. The evidence finds that the intervention duration is highly persistent and that the hazard is time dependent. 相似文献

This paper deals with an estimation of phosphate mining cost function. Here, it is argued that other characteristics of reserves, besides their size, could be quite important in the cost function. The result of a cross-sectional analysis of phosphate mining in the world shows that reserve size and average total cost have a positive and modest statistically significant relationship in one of the two models. Among many qualitative characteristics and location factors tested in this paper, overburden, grade, ore/product ratio, water availability, and the price of capital are significant with expected signs. Finally, the results confirm the existence of economies of scale in phosphate mining which seem to be more related to mining technology than to reserve size. 相似文献

By means of application of the production model, this paper establishes a total efficiency model of production factors and realizes scientific measurement of intensive productive benefit of industrial enterprises by computing economic benefit of intensive production. This will provide scientific foundation for enhancing the combination quality of production factors and improving the intensive level. 相似文献

土地利用功能分区与用途分区的差异比较研究——以山东省泰安市为例 总被引:2,自引:0,他引:2
土地利用功能分区有其产生的必然性;通过对因内外土地利用分区的相关研究,从分区内涵、目的、依据、类型等方面比较分析了土地利用功能分区与上一轮规划普遍采用的用途分区的差异,并对功能分区的内涵、特点及分区方法进行了研究;以山东省泰安市为例,进行了土地利用功能分区,将泰安分为中心城镇区、重点开发建设区、风景名胜旅游区、生态环境保护区、基本农田保护区等5个土地利用功能区,并指出了功能分区相比于用途分区在土地利用管理方面具有的优越性. 相似文献
