In this paper we introduce a complete duality theory based on directional distance functions. This duality theory parallels the duality theory based on radial distance functions in Färe and Primont (1995). 相似文献

Economic reforms,efficiency and productivity in Chinese banking 总被引:1,自引:0,他引:1
This paper analyzes the impact of banking reforms on efficiency and total factor productivity (TFP) change in Chinese banking
industry. Using an input distance function, we find that joint-equity banks are more efficient than wholly state-owned banks
(WSOBs). Furthermore, both WSOBs and joint-equity banks are found to be operating slightly below their optimal size, suggesting
potential advantages in expansion of their businesses. Overall, TFP growth was 4.4% per annum for the sample period 1993–2002.
Joint-equity banks experienced much higher growth in TFP (5.5% per annum) compared to the WSOBs (1.4% per annum).

Our main objective is to set out and apply a SEEA-based methodology to reflect the true value of forest resources in India's national and state accounts. We establish that a “top-down” approach using available national databases is both feasible and desirable from a policy perspective. In this paper, we address four components of value creation in forests: timber production, carbon storage, fuelwood usage, and the harvesting of non-timber forest products. The results of our analysis suggest that prevailing measures of national income in India underestimate the contribution of forests to income. The income accounts of the Northeastern states in particular are significantly understated by these traditional (GDP/GSDP) measures. We are also able to identify some states which performed poorly in the context of our sustainability framework, reflecting natural capital losses due to degradation and deforestation. Our results highlight the need to integrate natural resource accounting into the national accounting framework in order to generate appropriate signals for sustainable forest management and for the conservation of forest resources which are widely used by the poor in India, as well as being significant stores of national wealth. 相似文献

Outsourcing, Imports and Labour Demand 总被引:7,自引:0,他引:7
This paper examines the effects of purchased services and imported intermediate materials on the labour demand for different skills in German manufacturing sectors. We derive and estimate a factor demand system based on the generalised Box–Cox cost function nesting both the normalised quadratic and the translog functional form. We find that the impacts of output and capital growth are more important in explaining the demand for heterogeneous labour than substitution effects between labour and non–labour inputs. Similarly, the increasing use of both imported materials and purchased services is a consequence of output growth rather than input substitution.

This paper investigates the link between trade and environment by exploring the effects of green tariffs on innovation, location of production and the environment. It shows that tariffs levied on polluting goods could result in less world pollution than global harmonization of environmental standards by inducing more pollution-abatement R&D effort and generating lower unit emissions from production. Specifically, green tariffs reduce pollution by (1) shifting production to the region where environmental standards are respected, (2) inducing the firm in the clean country to engage in more abatement R&D by granting it a higher market power/share in its home market, (3) instigating green R&D investment by deterring delocation. When these outweigh the R&D-creating effect of environmental harmonization in the dirty country, green tariffs bring about a cleaner environment. 相似文献

There is currently substantial interest in valuing various services provided by different ecosystems. Concurrently economists have ascribed substantial effort on expanding traditional forest accounting systems by environmental services. This paper contributes to curtailing the existing gap between green accounting theory and applications for valuing forest ecosystem services. The multitude of links between forest ecosystem services and economy are characterized by the theoretical model for forest-economy interactions. By utilizing recently updated data we also incorporate empirical value estimates of these services comparable to other goods into Finnish forest accounting system. Finally, we discuss some problems encountered and clarify the interpretation of some value estimates incorporated to national forest account. 相似文献

有效供给不足抑制中国消费需求——从长短期消费函数看消费不足的问题 总被引:1,自引:0,他引:1
2005年是中国经济改革的关键一年,但目前宏观经济中出现了GDP增速减缓和消费需求疲软的突出矛盾。如何解决这一矛盾?相关文献通常在凯恩斯短期消费函数的基础上,认为消费拖累了GDP增长,并建议实施提高消费倾向、刺激消费需求的宏观消费管理政策。文章通过长期消费函数分析后发现是有效供给不足压抑了消费。因此,文章建议从加强供给管理入手,为社会提供更多的有效供给才是化解宏观经济矛盾的战略选择。 相似文献

In the recent decade, there has been observed across the Central and Eastern European states the regulatory trend towards the increase of the non-financial (first) pension pillar size at the expense of the financial (second) pillar. It tends to question the consequences of this shift for the future retirement benefits. Applying the portfolio approach we address this issue by running a series of simulations to find out how to allocate pension contributions between both pillars in an optimal way. Our study contributes to the existing literature as follows. First, we do not perform the assessment of the predetermined regulatory solutions, but we look for an optimal one. Moreover, we allow our optimal rule to be time-varying, if necessary, which would be a true novelty in this research area. Second, we do not base our estimates on historical trends; rather, we apply the long-term economy’s projection to account for the society’s ageing impact, which is a crucially important factor for the solvency of the pension system. Adapting some of the simulation assumptions to fit the Polish case, our results confirm that current regulations underestimate the role of the capital pillar and the optimal allocation between both pillars should be time-varying. 相似文献

选用船舶工业宏观数据和资源环境约束等作为基础数据,运用方向性距离函数和ML指数测算了中国船舶工业绿色全要素生产率(Total Factor Productivity),通过面板模型系统考察了环境规制、技术进步对中国船舶工业绿色全要素生产率的作用。发现从长远来看,绿色全要素生产率呈增长趋势且具有明显的收敛特征,技术进步和技术效率共同推动船舶工业绿色全要素生产率的增长,但整体上绿色全要素生产率低于传统全要素生产率。运用动态面板模型分析中国船舶工业绿色全要素生产率的影响因素,结论表明:较高的技术水平能显著提高绿色全要素生产率,而对国际市场的过度依赖阻碍了船舶工业绿色全要素生产率的增长。环境规制对船舶工业绿色全要素的增长已经带来"补偿效应"从而提高了中国船舶工业的国际竞争力,为考察船舶工业绿色竞争力提供了新的视角。 相似文献
