The nonperforming loans (NPLs) are co-generated by creating the profit in a bank, and this article build a joint production model to measure the reduction cost of nonperforming cost. By using a data set of China’s 13 commercial banks, the conclusions show that the reduction cost of NPLs is lower, which suggests that it is not a good choice for China’s commercial bank to hold the NPLs. 相似文献

This paper presents new developments on the state-contingent theory of production under uncertainty with stochastic prices. Our main purpose is to generalize the usual finite discrete state-contingent production model to infinite dimensional, possibly uncountable spaces which look like a more realistic framework. Usual duality results are established in this general context, shedding some light on the links between risk-neutral probabilities and shadow prices. A direct generalized production risk premium is defined and is shown to be independent of the inputs level when the technology is output translation homothetic. In such a case, the technology exhibits constant absolute riskiness. We thank Bob Chambers for his helpful comments. 相似文献

Does Environmental Protection Lead to Slower Productivity Growth in the Chemical Industry? 总被引:9,自引:0,他引:9
Efficiency and productivity growth is measured at the three-digit SIC level for six chemical industries for 1988–1993. The directional distance function is used to measure the lost chemical manufacturing output and the overproduction of toxic chemical releases. Total factor productivity growth is decomposed into a product of efficiency change and technical change. Accounting for toxic chemical releases, productivity grows at anannual rate of between 2.4% and 6.9%. We find no evidence that environmental protection measures reduce productivity growth. 相似文献

This paper develops the notion of parallel-neutral technical change for inputs and outputs. It is shown that parallel-neutral technical change generalizes existing radial notions of neutral technical change. A taxonomy of the structural consequences of parallel-neutral technical change is developed. 相似文献

我国不同类型工业企业生产效率的区域差异研究 总被引:4,自引:1,他引:4
工业企业生产效率是一个国家或地区工业发展水平的重要标志,我国各种类型企业由于所有制形式不同,其运作机制和效率也有差异,本文通过应用Cobb-Douglas生产函数模型,并利用充足的数据分析了分省加总的不同类型工业企业的生产及其效率。研究得出我国1999~2002年,对几乎绝大多数省份而言,国有及国有控股企业的生产效率最低,而生产效率最高的企业是三资企业,同时研究也表明,在区域层面上来看,东部地区的各种类型企业生产效率比其他地区的生产效率高20%以上,这要求以后在研究区域差异时应更多关注区域生产的差异。 相似文献

With the conclusion of Phase I trading of SO2 allowances, the EPA declared the allowance trading policy to be a success. The time had come to include cap-and-trade programs in the arsenal of effective policy tools. In terms of reducing atmospheric emissions of sulfur dioxide, the program appears to be successful. It is not clear, however, whether or not the program has minimized the cost of achieving the emission reductions. The measure of the true success of a market-based incentive program, however, has yetto be quantified: Has the program resulted in converging marginalabatement costs across participant plants? In this study I report theshadow prices of Phase I power plants from 1994 to 1998 anddetermine that there are more costs to be saved within theambitious public policy experiment. 相似文献

Previous empirical studies examining the impact medical residents have on hospital productivity have made a priori assumptions about whether medical residents are inputs (labour providing patient care) or outputs (students receiving mandatory training under the supervision of an attending physician) when specifying their estimating equations. We shed light on the role medical residents play in hospital production by using a data-driven parametric approach based on the directional technology distance function. Our primary goal is to assess the extent to which one of the two roles of medical residents empirically dominates the other and to see whether the role varies across different types of hospital. Using the American Hospital Association data from 1994 to 2010, we find that residents are inputs in all rural and public non-teaching hospitals, but they are outputs in urban-area not-for-profit teaching hospitals. We also demonstrate that the status of residents is related to the case-mix index and can vary with hospital size. 相似文献

This paper examines the generalization of the regulated production function. It characterizes the set of admissible regulatory
constraints that are compatible with the existence of a regulated production function in a sufficiently weak framework to
encompass the usual rate-of-return constraints à la Averch and Johnson and value constraints. 相似文献

江苏省水稻生产投入要素及影响因素实证研究 总被引:7,自引:0,他引:7
以江苏省最主要的粮食作物水稻为例,按照2004年分县纯收入水平,以该省22个县的354户水稻种植户2005年横截面数据为样本,运用扩展的C—D生产函数,就投入要素及品种认知、农业生产决策者个人特征等影响因素对水稻生产的作用进行了研究。估计结果显示:目前土地仍是影响江苏省水稻产出的最主要因素,化肥在水稻生产上仍发挥着重要作用。随着水稻良种良法配套栽培的推广,农户水稻品种认知对水稻生产的重要性得到显现。鉴于耕地灌溉条件对水稻生产的影响非常明显,政府应加大对农田水利设施的建设投入。 相似文献

This article presents a productivity benchmarking study of Australian water utilities using stochastic frontier analysis of the input distance function. It identifies total factor productivity (TFP) trends and comparative levels and, through decomposition, explores some of the reasons for productivity change. Productivity is found to have declined between 2006 and 2010 over all regions, with the smallest declines in the four major urban Victorian utilities and the largest declines among the regional Victorian urban water utilities and the major utilities in other states. Comparative technical efficiency analysis finds the major urban Victorian utilities were more efficient than the average water utility, while the regional Victorian urban water utilities and the major utilities in other states were of below‐average technical efficiency. The benchmarking method employed in the study may be relevant to economic regulation. 相似文献

The mining industry is an important sector of the national economy, which provides essential support for energy and other resources for economic development. Industrial linkage and economic distance are two different concepts in measuring the correlationship of different industries, in this article, we apply the model that combines both of them to analyse the industries significantly influence the mining industry. We find that electricity and heating industry, and the mining industry itself from forward linkages have greatly influenced the mining industry, and the industries from backward linkages affect mining industry are changing with industrial economic transformation. We also find resources can flow across several regions only after 2007, which means the role of geographical factors limiting long-range transportation of resources is weakening after 2007. And we explain how resources flow among various regions during 1997 ~ 2007. Based on the findings above, policy implications from the empirical results obtained are discussed. 相似文献

文章以Camanho和Dyson(2006)发展的群组效率指数法为基础,结合双曲线距离函数,在规模报酬可变的假设条件下,对中印两国银行业的经营效率进行了比较研究。结果显示,印度银行业群组效率在研究期间内基本上优于中国银行业,主要原因在于印度银行业生产前沿的生产率和群组规模效率的一致性都优于中国银行业,但中国银行业群组技术效率的一致性却均高于印度银行业。因此,简单地说印度银行业的效率高于中国银行业是不准确的。 相似文献

The cod stock in the North Sea is threatened by overexploitation. To recover this fishing stock, pressure needs to be reduced.
This implies that catch compositions with small amounts of cod are preferred by public policy makers. The present analysis
assesses the technological efficiency of fishing trips in terms of the substitution possibilities away from cod by considering
landings of cod as an undesirable output. A conservative non-parametric frontier technology approach imposing minimal assumptions
and based on directional distance functions is applied to explore alternative fishing activities for Danish gill netters operating
in the North Sea with the goal of reducing cod catches. Since performance on different fishing trips may be influenced by
the operating environment, a four-stage approach is applied to correct for exogenous factors (Fried et al., J Product Anal
12(3):249–267, 1999). The corrected directional distance function efficiency scores reveal the behavioural inefficiencies,
i.e., prospects for decreasing the catch of cod while catch of other species are increased.

We estimate production technologies of major dairy producing regions in the U.S. The simultaneity and sample selection biases are carefully corrected following the recent development in the literature. The commonly applied control function approaches are found to be misleading in correcting for biases of coefficient estimates on flexible and quasi-fixed input variables. We show that the emerging dairy regions have relatively higher aggregate productivity than traditional regions. Dynamic decomposition results indicate that surviving farms play a more important role in regional productivity growth than entering and exiting farms. Farm- and regional-level driving forces of farm productivity are also examined. 相似文献
