This article is a comment on The Fallacy of Washington Consensus and the Role of the Government: Interpreting Some Chinese Contributions to Development Policy from Aspects of Chang'e 4 by Jinghai Zheng.The comparison between how equilibrium concepts are used in economics and natural sciences is extended to areas such as biology, chemistry and convex optimization in mathematics and is discussed on the basis of the state's role in economics and general equilibrium theory. 相似文献

We examined the productive efficiency of the interior sawmilling industry in British Columbia using stochastic frontier analysis. Prior sawmilling studies using this method have neglected the multi-output nature of sawmills. To accommodate both lumber and chips as outputs, we used a ray production function and adopted it into the stochastic frontier framework. A translog functional form was specified with three inputs (i.e., capital, labour, and roundwood) and applied to five years (2003–2007) of mill specific production data. The ray production function is flexible allowing factor productivity to vary with the output mix. Results indicated the presence of both economies of scale and technical inefficiency. This suggested that a long-run equilibrium had not yet been reached during this time and might explain recent restructuring occurring in this region. 相似文献

We discuss the design of interactive, internet based benchmarking using parametric (statistical) as well as non-parametric (DEA) models. The user receives benchmarks and improvement potentials. The user is also given the possibility to search different efficiency frontiers and hereby to explore alternative improvement strategies. Implementations of both a parametric and a non-parametric model are presented. 相似文献

Spatial Welfare Economics Versus Ecological Footprint: A Sensitivity Analysis Introducing Strong Sustainability 总被引:1,自引:0,他引:1
The aim of this paper is a sensitivity analysis with the core-periphery model of ‘new economic geography’ put forward in Grazi
et al. (Environ Resour Econ 38:135–153, 2007). This model comprises interregional trade, agglomeration advantages and resource (land) use or environmental externalities.
Grazi et al. (2007, GBR) compare a social welfare (SW) indicator with the ecological footprint (EF) indicator for measuring spatial sustainability
of a set of land use configurations. Their main result is that the SW and the EF indicator can yield completely different
rankings and only for extreme parameterizations of environmental externalities the rankings coincide. We adapt the model by
interpreting total natural land as a resource constraint and differentiate between weak and strong sustainability. In a sensitivity
analysis we show that the main results of GBR (2007) correspond to the case of weak sustainability in our adapted model version. In the case of strong sustainability our adapted
model version shows the same welfare rankings for both indicators without the extreme parameterization that is necessary to
obtain the same results in the original GBR (2007) model. 相似文献
