国有商业银行费用偏好与组织绩效的实证分析

单一国有产权结构、出资人监督缺位和委托代理问题共同决定了国有商业银行费用扩张偏好.实证结果表明,费用规模扩张侵蚀了出资人利润性收益空间,成为国有商业银行利润率指标偏低的解释因素.因此,国有商业银行制度变迁必然包含能够抑制费用偏好的制度工具创新.政府宏观经济目标的退出可以使出资人硬化利润约束,但在政府效用函数不可能全面退出国有商业银行的现实背景中,通过引进在位寡头之间的竞争可以为国有商业银行利润目标约束硬化提供外在制衡条件;同时,产权多元化改革基础上的银行治理结构完善则是解决委托-代理问题下经营者费用偏好问题的彻底措施.     

对于劳动力市场的性别歧视的实证分析——以美国的2007年劳动力市场的数据为例

通过借鉴美国2007年美国劳动力市场的数据,对于劳动力市场中的性别歧视现象作了实证分析。考虑到了影响工资收入的职业类型、技术差异,劳动者偏好等影响因素对于劳动群里女性比例与该劳动群体里的工资收入进行了多元回归分析。该研究结果对于改善较不成熟的中国劳动力市场的就业问题具有一定的借鉴意义。     

Keynes and a post-Keynesian controversy over the effect of debt on income expansion

The paper considers arguments of Robertson (1938) and Asimakopulos (1983) that the Keynesian multiplier expansion of output may be constrained by debt implicitly incurred in the financing of autonomous investment necessary to start the multiplier process. The task of this essay is to show that within the ‘short-period’ and static analytical framework of Keynes, this line of reasoning regarding the adverse effects of debt on multiplier-induced expansions of output is unwarranted. Nevertheless it is concluded that if the Keynesian framework is abandoned in favour of a dynamic framework in the manner of a steady trend rate of growth - a choice dependent on how one conceives of the economy, as inherently static or dynamic - then such arguments have troubling implications. In particular, the dependence of Keynes's approach on credit and hence debt forges links between ‘short-periods' whose distinctness from one another is crucial to Keynes's result.     

Skidelsky's Keynes: a review essay

Abstract

The paper examines the pro-work doctrines of four writers who were connected with the ‘utopian’ and ‘romantic’ critique of classical economics in the nineteenth century. These authors are Charles Fourier, Thomas Carlyle, John Ruskin, and William Morris. All four argued that the problem of work aversion stemmed from the existing institutions of capitalist society, and could be overcome by the creation of an alternative system of production. Their aim was to create a future society in which work could be experienced as a positive activity. The paper argues that the views of the aforementioned authors provided an important counterchallenge to the classical economists' conception of work as a disutility.     

Gender preference and transfers from parents to children: an inter-regional comparison

This paper examines whether parents exhibit gender preference in the allocation of family resources to their adult children. Gender preference is defined in the context of an altruistic model for inter-vivos transfer from parents to children extended to include educational investment. Data from the Health and Retirement Study (United States) and the Korean Longitudinal Study of Ageing are used to show that the degree of gender preference differs across these culturally distinct regions. Among Korean families, empirical results point to male preference as sons receive larger inter-vivos transfers and attain higher levels of education compared with daughters. In contrast, the evidence pertaining to gender preference among American families points to daughter preference as inter-vivos transfers and educational investment is generally higher among female adult children.     

A lottery-preference-based explanation of realized kurtosis puzzle in Chinese stock market

High kurtosis corresponds to fat tails on both sides and under risk-aversion assumption investors’ dislike of left-tail loss outweighs their preference for right-tail gain. Therefore, high kurtosis characteristic of stock should predict high expected returns. However, the high-frequency-data-based empirical results on Chinese stock market are just the opposite, which we refer to as the ‘realized kurtosis puzzle’. Using the double sorts and firm-level cross-sectional regression methods, we further demonstrate investors’ preference for lottery-like stocks or lottery preference is key to solve the puzzle. Our further empirical research verifies stocks with higher retail investors’ shareholding proportion and unavailable for short show stronger ‘realized kurtosis puzzle’. In addition, the puzzle is particularly significant in high lottery preference periods while less apparent in low lottery preference times.     

Productivity and technical change: the case of Taiwan

This paper analyses productivity growth in 16 of Taiwan's manufacturing industries during the period 1978–1992. The non-parametric Data Envelopment Analysis approach is used to compute Malmquist productivity indexes. These are decomposed into efficiency change and technical change. The latter is further decomposed into an output bias, an input bias and a magnitude component. In addition, the direction of input bias is identified. Empirical results indicate that the sector's TFP increased at a rate of 2.89% per annum, which could be ascribed to a technical progress (2.56%) and an efficiency improvement (0.33%).     

基于碳排放的闭环供应链政府奖惩机制研究

温室气体的排放问题已成为国际社会亟待解决的问题,解决这一问题的必由之路就是通过降低产品碳排量实现从源头上减排。本文研究由一个制造商和一个零售商组成的逆向供应链系统,建立了政府实施回收奖惩机制的动态博弈模型,比较分析了有无政府回收奖惩机制两种情形下零售商的回收比例、供应链参与方的期望利润和产品的碳排放总量。研究结果表明,政府回收奖惩机制提高了回收比例和碳减排水平;当再制造减排程度较小时,政府回收奖惩机制降低了碳排放总量;基于消费者低碳偏好的政府回收奖惩机制提高了制造商和零售商的利润,更大程度的降低了产品总碳排放量;政府回收奖惩机制下较小的目标回收率能够最大化零售商利润。     

The effectiveness of home energy audits: A case study of Jackson,Wyoming

This study examines the factors that influence households to adopt modifications recommended by home energy audits and whether these audits lead to significant reductions in electricity use. Household decisions after the audits are recorded along with the corresponding recommended modifications and the offers for co-funding. A discrete choice model of the household decision after the audit is estimated. The results indicate that the potential improvement in heating efficiency from the proposed modifications increase the probability of implementing conservation measures. Co-funding offers also significantly raise the odds of accepting the modifications but are relatively less important than anticipated efficiency improvements. Several approaches are used to determine whether and how much energy is saved after the audits. Electricity demand models are estimated using data two years before and after each household audit. For households who decide to modify their houses after the audit, monthly average electricity use per square foot decreases 7%. While there is an estimated 2% reduction in electricity use attributed to the audit by households who decided not to adopt the proposed modifications, this reduction is not statistically significant, casting doubt on the presence of modifications in behavior from the audit information itself. For all households audited, the results from the electricity demand models suggest that the LVE home energy audit program reduced household electricity use 4.7%. In contrast, a differences-in-differences approach using synthetic control groups based upon a smaller but still sizeable sample of 2000 observations finds that home energy audits reduce household electricity use by more than 10%. Overall, these findings suggest that home audits result in modest but significant reductions in energy use and that co-funding encourages investments that otherwise may not be privately optimal.     

Agricultural landowners⿿ response to incentives for afforestation

Previous research has shown that afforestation of agricultural land is a relatively low-cost option compared to energy-based approaches for mitigating net carbon dioxide emissions, and that financial incentives affect landowner behavior and can be used to increase carbon sequestration on private land. In this paper we use stated preference data from private landowners in the Pacific Northwest region of the U.S. to examine the key factors affecting participation in an incentive program for carbon sequestration through afforestation. We also estimate the corresponding potential for carbon sequestration and its cost. Our results suggest that incentive payments would significantly and positively affect landowners⿿ level of enrollment in a tree planting program.
