环境不确定性与企业党员高管的创新“稳定器”效应

本文选取2010—2019年A股上市公司作为研究样本,研究高管党员身份在企业创新面临环境不确定带来冲击时的“稳定器”效应及其内在机制。研究发现：环境不确定性的提升抑制了企业创新,高管党员身份能通过降低研发支出挤出程度和优化融资环境两个渠道有效缓解环境不确定性的创新抑制效应。党员高管的创新“稳定器”效应更多地体现在环境不确定性增加的阶段,在平稳发展时期,应平衡好党组织参与企业治理与企业创新发展自主权的关系。全面从严治党战略的实施使党员高管决策风格更加稳健、保守,降低了企业风险承担,同时强化了面临环境不确定性时高管党员身份的“创新稳定器”作用。在当前企业创新面临高环境不确定性的大背景下,本文研究一方面丰富了党组织参与创新治理的理论依据,另一方面为高不确定性背景下优化企业创新环境提供了可实践路径。     

Risk Aversion, Intergenerational Equity and Climate Change

The paper investigates a climate-economy model with an iso-elastic welfare function in which one parameter measures relative risk-aversion and a distinct parameter measures resistance to intertemporal substitution.We show both theoretically and numerically that climate policy responds differently to variations in the two parameters. In particular, we show that higher but lower leads to increase emissions control. We also argue that climate-economy models based on intertemporal expected utility maximization, i.e. models where = , may misinterpret the sensitivity of the climate policy to risk-aversion.     

征税成本领先性假设与中国税务组织结构优化——兼析中国国税、地税机构是否存在合并趋势

本文从征税成本领先性假设出发探讨了中国税务组织结构的优化问题 ,并分析了社会各界广泛关注的中国国税、地税机构是否存在合并趋势的问题。本文在对中国现行税务组织机构运行绩效考察的基础上 ,发现中国征税成本曲线呈抛物线状 ,表明中国征税成本正呈递减趋势。以此为出发点 ,本文详细论证了中国国税、地税机构不存在合并的趋势 ,相反 ,分设更为彻底却是今后的发展趋势 ,得出了与一般看法不同的结论 ,并对优化中国税务组织结构提出了政策建议     

Evaluating Projects and Assessing Sustainable Development in Imperfect Economies

We are interested in three related questions:(1) How should accounting prices be estimated?(2) How should we evaluate policy change in animperfect economy? (3) How can we check whetherintergenerational well-being will be sustainedalong a projected economic programme? We do notpresume that the economy is convex, nor do weassume that the government optimizes on behalfof its citizens. We show that the same set ofaccounting prices should be used both forpolicy evaluation and for assessing whether ornot intergenerational welfare along a giveneconomic path will be sustained. We also showthat a comprehensive measure of wealth,computed in terms of the accounting prices, canbe used as an index for problems (2) and (3)above. The remainder of the paper is concernedwith rules for estimating the accounting pricesof several specific environmental naturalresources, transacted in a few well knowneconomic institutions.     

Economic reforms,efficiency and productivity in Chinese banking

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).      

Structural Decomposition Analysis of Physical Flows in the Economy

Many environmental problems can be attributedto the extraction and emissions of physicalsubstances. Increasing our understanding of theeconomic and technological driving forcesbehind these physical flows can contribute tosolving the environmental problems related tothem. The input-output framework is a usefulsetting in which to integrate detailedinformation about economic structure andphysical flows. In this article a specificmethod in input-output analysis is reviewed,namely Structural Decomposition Analysis (SDA).It is based on comparative static analysis,which decomposes historical changes of a policyvariable into determinant effects. SDA has beenapplied, for example, to analyze the demand andtechnological driving forces of energy use,CO₂-emissions and various other pollutantsand resources. This article examines thetheoretical aspects of structuraldecomposition, in particular those concerningphysical flows and environmental issues.Furthermore, the article includes an extensivesurvey of empirical studies.     

Non-commitment in performance evaluation and the problem of information distortions

Auditing is modeled in a sequential game without commitment. The manager must decide whether and where to audit a worker's output, taking into account all interim information he has obtained. The worker will work just hard enough (and show it) to divert the manager from making an audit or cover up, withholding information about his work to make an audit more difficult. This usually raises the costs of setting work incentives, so incentives are softened, sometimes drastically. Moreover, when a worker's on-the-job information is valuable for entrepreneurial decisions, work incentives must be softened to improve the internal flow of information.     

企业内部组织单元绩效评价:一项有效的制度安排

企业内部组织单元绩效评价是企业绩效评价体系的重要组成部分,是连接企业整体绩效评价与员工个人绩效评价的中间环节。应用委托代理理论对企业内部组织单元绩效评价的地位在理论上进行了分析,并对企业内部组织单元绩效评价的功能也进行了系统分析,认为企业内部组织单元绩效评价是一项有效的制度安排,是解决企业内部组织委托代理链上委托代理关系的重要手段。     

Embodied and Disembodied Technical Change in Fisheries: An Analysis of the Sète Trawl Fishery, 1985–1999

Overfishing and excess capacity in mostfisheries around the world have generated considerableand increasing concern about their biological and economic performance ramifications. Theseproblems, in part, stem from substantialinvestment in technical improvements to boats andequipment in fishing fleets, which exacerbatesexcess fishing capacity and low returns tofishing effort and investment, given regulatoryand biological constraints. However, little attempt hasbeen made to quantify the extent or effects oftechnical change in fisheries. In this paper, we usedetailed data on innovation patterns for 19vessels in the Sète trawl fleet of southernFrance to evaluate the contributions oftechnical change to catch rates. We find thatembodied technical change enhanced productivity by approximately one percent per year between 1985 and 1999, but that external (disembodied) events counteractedthis trend, causing a net output decline ofabout three percent per year.
