对于国有企业(及国家机关部门和事业单位)来说,建立“外派”会计制度是内在的要求,应该坚持做好。“外派”会计是财务监督会计,与企业内部管理会计并行不悖。不过,现行的会计委派制确实增加了企业经理人员和委派会计人员或财务总监之间产生对立或合谋的可能性,某种意义上成为政府干预企业的新机制、新形式,这影响到会计委派制的实际效果。而由会计师事务所等中介服务机构来充当企业的财务总监的会计代理制却能较好地隔离政府与企业,并在两者之间形成适当的平衡。  相似文献

This dissertation aims at elucidating the history of Vernon Smith’s experimental economics by focusing its attention upon the three themes of rationality, minds and machines that assumed significance at different (albeit overlapping) stages of the development of Smith’s experimental economics with the help of his published and unpublished papers.Chapter 1 is devoted to the scrutiny of the form of rationality incorporated into the portions of Smith’s laboratory experiments whose results have usually been taken as corroborations of his “Hayek Hypothesis.” By bringing into the foreground Smith’s definite position on demand theory and its concrete instantiations on many different occasions, we make the case that Smith has consistently imposed by means of the induced value theory certain narrowly defined preference structures that have definite implications for the form of rationality instantiated in the laboratory.The main narrative in Chapter 2 concerns Smith’s intellectual interchanges with behavioral scientists in the early 1960s, more specifically, his reactions to behavioral scientists’ attempts at cognitive modeling. We present several reasons for interpreting Smith’s initiation of the attempt at the maximization-based induced value theory as an endeavor to discipline subjects’ minds. We also provide in Chapter 2 a portrayal of Smith’s missed opportunities to get involved in the large-scale laboratory experimentation projects pursued in the 1950s in close connection with several branches of psychology.Chapter 3 consists of two parts. In Part 1, we describe the origin of mechanism design economics, and offer a detailed explanation of the analytical kinship between Smith’s “microeconomic system theory” and the standard conceptual framework utilized in mechanism design economics. Part 2 is devoted to describing the roles played by the computer in both Smith’s empirical research agenda and the theoretical, mechanism design research pursued by Stanley Reiter (one of Smith’s intellectual companions since the 1950s). Our historical narrative in Chapter 3 is intended to clarify that computer experience and computational theory drove the development of Reiter’ version of mechanism design economics, and that they also (partially) shaped some crucial events in the history of Smith’s version of experimental economics.JEL Classification: B21, B31, C90, C92, D02Prof. Philip E.

Passage of an Internal Revenue Service (IRS) overhaul bill in 1998 reflects the depth of American taxpayer frustration with the agency. We bring a constitutional, or rules of the game, perspective to tax enforcement. We examine political costs and benefits and agency discretion as reasons why tax enforcement by the government might deviate from the preferences of a representative citizen. We also examine prospects for reform. Lasting reform must alter the rules for deciding tax enforcement policy or the political pressures which yield excessive enforcement today will reemerge in the future.  相似文献

In a 1994 paper, extending the well-known incremental surplus subsidy scheme of Sappington and Sibley, Schwermer presented a non-Bayesian incentive scheme for regulating a Cournot oligopoly industry. This note designs an oligopolistic incentive scheme for a hierarchical Stackelberg model in which firms choose outputs sequentially.  相似文献

The paper attempts to identify the telecom-sector performance indicators, relevant economic variables, and institutional characteristics of a country that effect the process of privatization of state-owned telecom enterprises. Using standard duration analysis of a panel data, we demonstrate that the privatization incentives are not only shaped by the mobility of financial capital in a country but are also influenced by the degree of competitiveness of private sector participation in policy-making process. The empirical results also reveal the significant impact of productive efficiency in telecom service provision on its course to privatization. We thank an anonymous referee for helpful comments and suggestions. We are solely responsible for all mistakes.  相似文献

Taxation of Mobile Factors as Insurance under Uncertainty   总被引:1,自引:0,他引:1  
This paper considers the effects of the taxation of mobile factors, i.e., capital, under uncertainty. The wages earned by residents of a jurisdiction are uncertain due to random shocks. Since the uncertain wages in a jurisdiction depend on the amount of mobile capital employed in the jurisdiction, and since taxation alters the quantity of capital employed, taxation affects the riskiness of uncertain wages. In particular, the taxation of capital moderates the fluctuation of uncertain wages, thereby providing insurance. For this reason, jurisdictions use distortionary capital taxation even if lump‐sum taxation is available. In addition, this insurance effect counteracts the tendency toward too low tax rates on capital arising from tax competition, and possibly improves the efficiency of tax competition.  相似文献

Entry deterrence and innovation in durable-goods monopoly   总被引:1,自引:0,他引:1  
This paper investigates the efficiency of innovation investments in a durable-goods monopoly when a potential entrant threatens to innovate as well. We show that the durability of the good endows the monopolist with the power to discourage rival innovation since current sales alter the demand for a new generation of the good. The equilibrium is therefore determined not only by the incentive for intertemporal price discrimination in durable-goods monopoly, but also by the incumbent's concern for maintaining the technological leadership. We demonstrate that entry deterrence followed by no innovation always implies underinvestment in innovation.  相似文献

Background: Validation of overall survival (OS) extrapolations of immune-checkpoint inhibitors (ICIs) during the National Institute for Health and Care Excellence (NICE) Single Technology Assessment (STA) process is limited due to data still maturing at the time of submission. Inaccurate extrapolation may lead to inappropriate decision-making. The availability of more mature trial data facilitates a retrospective analysis of the plausibility and validity of initial extrapolations. This study compares these extrapolations to subsequently available longer-term data.

Methods: A systematic search of completed NICE appraisals of ICIs from March 2000 to December 2017 was performed. A targeted search was also undertaken to procure published OS data from the pivotal clinical trials for each identified STA made available post-submission to NICE. Initial Kaplan-Meier curves and associated extrapolations from NICE documentation were extracted to compare the accuracy of OS projections versus the most mature data.

Results: The review identified 11 STAs, of which 10 provided OS data upon submission to NICE. The extrapolations undertaken considered parametric or piecewise survival models. Additional data cut-offs provided a mean of 18 months of OS beyond the end of the original data. Initial extrapolations typically under-estimated OS from the most mature data cut-off by 0.4–2.7%, depending on the choice of assessment method and use of the manufacturer- or ERG-preferred extrapolation.

Conclusion: Long-term extrapolation of OS is required for NICE STAs based on initial immature OS data. The results of this study demonstrate that the initial OS extrapolations employed by manufacturers and ERGs generally predicted OS reasonably well when compared to more mature data (when available), although on average they appeared to underestimate OS. This review and validation shows that, while the choice of OS extrapolation is uncertain, the methods adopted are generally aligned with later-published follow-up data and appear appropriate for informing HTA decisions.  相似文献

作为中国财政转型的方向,公共财政自提出已经走过了近10年的历程.以此为脉络,回顾梳理这些年的财政工作,总结公共财政的建设经验,颇多令人鼓舞和值得深思之处.在中国千年未有的经济社会转型的探索中,财政改革与发展的转型之路已经锁定在公共财政轨道上,尤其是十六大以来政府公共职能归位、公共服务均等化、公共理财规范化等一系列重要理念的明确,不仅在不断丰富公共财政的理论内涵,而且被贯彻于指导和推进财政改革实践,为以科学发展观统筹全局和促进社会和谐做出贡献:政府财政支出导向和结构发生了意义深远的变化,关注民生成为重中之重;"以政控财"逐渐具备了更加规范的制度依托;"以财行政"的实力大大提高,调控市场配置资源偏差的能力不断加强;财政服务于改革与发展的努力,正进入良性循环.  相似文献
