有限理性经济人假说下的财务报告列报和使用

本文在分析西蒙的有限理性经济人假说理论的基础上,论述了其经济意义:知识具有时间和主体的相对性;一般人们发现和选择的只能是满意的方案而不是最优方案;有限理性经济人在进行经济活动时,一般遵循的是程序理性穴Procedualrationality雪而非结果理性穴Rationalityofoutcome雪;无论是完全理性经济人假说,还是有限理性经济人假说,其本质都是经济人假说,经济人的行为动机一定是追求利益最大化。根据这一意义,提出了在有限理性经济人假说理论下,财务报告所列报的是根据财务报告目标要求,依据会计规则所产生的财务信息,这种财务信息必定存在“规则性失真”和信息的不完全性;此外,会计规则内容在不同时期会发生变动,以适应不同时期不同利益集团之间利益协调的改变,为此,财务报告的列报内容也会发生相应的改变。这一结论的现实意义是:人们使用财务报告时,首先,必须具备必要的经济学、会计学、管理学等相关知识;其次,对财务报告所提供的信息应允许有一定范围的“失真”;第三,对信息的不全面性和不完整性以及财务报告内容的变化要有充分的估计和思想准备。只有这样,才能正确地理解和使用财务报告。     

猕猴桃产业发展的奇迹——新西兰猕猴桃的案例启示

中国已是世界上最大的猕猴桃生产国,但产品出口仅占全球的2%.而新西兰从猕猴桃原产地中国引入猕猴桃后,一跃成为目前世界上最大的猕猴桃出口国.文章深入研究新西兰猕猴桃产业发展和创新的经验,包括采用"Kiwigreen"生产措施,成立生产者控股的"Zespri"公司,对猕猴桃实行统一的"Zespri <'TM>"品牌营销和培育猕猴桃新品种等;同时分析了中国猕猴桃产业发展存在的问题和不足,提出发挥中国猕猴桃原产国的优势,积极培育红心猕猴桃等新品种,提升猕猴桃产品质量以及实施以"地理标志保护"为特色的品牌营销等对策建议.这些有助于挖掘中国猕猴桃产业的潜力,促进中国从猕猴桃生产大国向出口大国转变.     

Using dead reckoning in economic projections

Economics is an inexact science, measurement of basic data is at best approximate, and most interesting relationships change relatively rapidly in developing countries. Key variables determining economic prospects are often impossible to include into models. Models and their mathematical algorithms however are deceptively precise, which often complicates the process of constructing and using economic projection models in developing countries.This paper will examine those macro models intended for operational policy purposes and how they are used. These models try to be analytically good and have sufficient plausibility to influence policy. Thus, a great deal of judgment is required in constructing, using, and interpreting projection models in developing countries: the “dead reckoning” element.     

河南省林果业循环经济发展趋势

河南作为国家发改委确定的循环经济建设试点省份,近年来积极探索适合该省省情的循环经济发展模式,取得了一定成效,但同时也存在发展水平不高、区域发展不均衡等问题。文章就河南省林果业循环经济发展的优势、必要性、存在的问题及未来发展趋势进行简要的分析与探讨。该文指出了河南林果业循环经济发展面临的问题:一是林果业循环经济基础发展薄弱;二是循环经济相关法律有待完善,政府调节作用有待加强。对于未来河南林果业循环经济发展趋势,一是需要政府协调引导,形成发展合力;二是需要龙头企业带动,延长产业链条;三是需要农户积极参与,践行循环经济。让更多农户掌握生态林果栽培技术,将更多新技术与高效节能新装备与产品推广下去,促进林果业循环经济在更广阔的范围开展下去,让循环经济真正深入人心,实现河南林果业种植地区户户参与、人人参与的良好局面。     

创新驱动下中国区域高质量发展——基于平衡充分发展水平的门槛分析

创新驱动是破解中国区域不平衡不充分发展的突破口,是实现高质量发展的助推器。采用2003—2017年中国30个省市(因数据缺失,不包括西藏地区和港澳台地区)面板数据,运用全局参比Malmquist模型测度了中国区域高质量发展水平,并通过构建指标体系分别对中国各省市的平衡发展和充分发展水平进行了评价,然后通过门槛回归模型分析了在不同平衡和充分发展水平下创新驱动对于高质量发展的影响机制。结果发现:①区域高质量发展水平呈现出先下降后上升的变化趋势;②各省市平衡和充分发展水平均呈现上升趋势,但各省市之间的变化情况差异较大,有明显的空间集聚特征;③在不同的平衡及充分发展水平下,创新驱动对高质量发展的影响机制是不同的,当平衡充分发展水平较低时,创新驱动对高质量发展没有显著影响;当平衡充分发展达到一定水平时,创新驱动对高质量发展起到一定的促进作用;随着平衡充分发展水平的进一步提高,创新驱动对高质量发展的促进作用越来越大。     

The Early Careers Of Engineers And The Accumulation Of Skills In The Canadian Economy

In this paper we use world cycling records to study the pattern of technological development of the track bicycle. We find that there is a strong evidence of ‘contagious’ effects among cycling records which in turn provides indirect evidence of ‘contagious’ effects among technological innovations. Interestingly, the ‘contagiousness’ of records is not a salient characteristic of track and field competitions where, arguably, technology plays a smaller role.     

The effect of mergers and acquisitions on environmental,social and governance performance and market value: Evidence from EU acquirers

This study explores the effect of environmental, social, and governance (ESG) performance on market value and performance in the context of mergers and acquisitions. We examine whether acquisition of targets with better ESG performance can help acquirers to increase their own ESG performance and whether the market values the increased ESG performance positively. Moreover, we explore whether the acquisition of targets with better ESG performance affects the market value of acquirers. For this study, we utilize a sample of 100 European mergers and acquisitions between 2003 and 2017, for which matching data on the ESG performance of both the target and acquiring firms are available. Our results show that the postmerger ESG performance of the acquirer increases following the acquisition of a target that has higher ESG performance than that of the acquirer in the premerger stage, whereas the postmerger market value of the acquirer increases following an increase in the acquirer's postmerger ESG performance in relation to its premerger ESG performance. Finally, we provide partial evidence of a positive relationship between the postmerger market value of the acquirer and the acquisition of a target with higher ESG performance than itself in the premerger stage.     

基于中国股市微观结构的流动性与执行成本分析

运用市场微观结构理论来分析中国股市的交易制度、流动性和执行成本后发现:(1)在佣金和交易税相等的条件下,B股的知情交易者执行成本普遍大于A股,导致B股的流动性小于A股,买卖价差显著大于A股,表明投资者对B股交易要求较高的风险报酬;(2)一旦控制住执行成本中普通交易者对知情交易者所要求的风险补偿,A、B股买卖价差的区别就消失了。因此,证券管理部门应在B股市场引入做市商制度并在微观结构理论的指导下,加强交易监管系统,从而提高B股的流动性并降低其执行成本。     

国民收入分配对投资消费失衡的影响分析

投资消费失衡严重制约了我国国民经济持续健康发展,国民收入在企业部门、政府部门、住户部门之间的不合理分配是导致我国投资消费失衡的根本原因。国民收入分配对投资消费失衡影响的数理分析和实证分析表明,对投资率、消费率最有影响的是企业部门在国民收入分配中的比重,其次是政府部门在国民收入分配中的比重,影响最小的是住户部门在国民收入分配中的比重。     

The multiple unit auction with variable supply

Summary. The theory of multiple unit auctions traditionally assumes that the offered quantity is fixed. I argue that this assumption is not appropriate for many applications because the seller may be able and willing to adjust the supply as a function of the bidding. In this paper I address this shortcoming by analyzing a multi-unit auction game between a monopolistic seller who can produce arbitrary quantities at constant unit cost, and oligopolistic bidders. I establish the existence of a subgame-perfect equilibrium for price discriminating and for uniform price auctions. I also show that bidders have an incentive to misreport their true demand in both auction formats, but they do that in different ways and for different reasons. Furthermore, both auction formats are inefficient, but there is no unambiguous ordering among them. Finally, the more competitive the bidders are, the more likely the seller is to prefer uniform pricing over price discrimination, yet increased competition among bidders may or may not enhance efficiency.
