Myopic loss aversion and the equity premium puzzle reconsidered

Benartzi and Thaler [The Quarterly Journal of Economics 110 (1995) 73–92] offer a quasi-rational explanation for the equity premium puzzle. We reconsider their methodology and, making a simple modification to it, find that their analysis is not robust.     

深化对马克思企业理论的研究

深化对马克思企业理论的研究既有助于澄清一些人认为“马克思没有企业理论”的误解,也有助于纠正企业理论研究中“言必称西方”的倾向,还可以为我国的企业改革实践提供指导。研究的途径有“回到马克思”、“依据变化了的实际分析马克思企业理论的‘合理内核’与时代局限”、“批判性地借鉴西方经济学的企业理论”等。     

产权观下我国企业会计目标构建问题研究

会计目标一直是西方会计界重点关注和研究的问题,近年来,我国会计理论界和实务界也对其投以越来越多的关注。本文试图从企业产权理论和制度变迁的角度,以利益相关者权益保护为主线研究会计目标,理清从受托责任观到决策有用观演进的必然性和合理性,并在分析英美、法德模式会计目标的差异后,结合当前我国会计准则国际趋同的背景,提出我国应确立以利益相关者权益保护为中心、以企业特征为导向、针对不同环境分别选择受托责任或决策有用为核心内容的会计目标构建思想。     

重构企业R＆D项目战略投资决策方法体系

传统的投资决策方法是一种建立在广泛应用的以货币的时间价值为基础的投资决策方法,它已越来越不能适应当今充满不确定性和竞争性的市场需要.实物期权方法比传统的折现现金流法（DCF）更适合来分析不确定条件下的投资决策问题,但仅凭实物期权方法还不能对不完全竞争环境下的企业R＆D项目战略投资问题进行准确分析和估价,而引入期权博弈理论恰好能克服这些缺陷.文章从理论上阐述了重构企业R＆D项目投资决策方法体系的可能性和必要性,并由此提出了研究的基本框架.     

Statistical Decision Problems and Bayesian Nonparametric Methods

This paper considers parametric statistical decision problems conducted within a Bayesian nonparametric context. Our work was motivated by the realisation that typical parametric model selection procedures are essentially incoherent. We argue that one solution to this problem is to use a flexible enough model in the first place, a model that will not be checked no matter what data arrive. Ideally, one would use a nonparametric model to describe all the uncertainty about the density function generating the data. However, parametric models are the preferred choice for many statisticians, despite the incoherence involved in model checking, incoherence that is quite often ignored for pragmatic reasons. In this paper we show how coherent parametric inference can be carried out via decision theory and Bayesian nonparametrics. None of the ingredients discussed here are new, but our main point only becomes evident when one sees all priors—even parametric ones—as measures on sets of densities as opposed to measures on finite-dimensional parameter spaces.     

Asymptotic expansion of S-estimators of location and covariance

By means of a straightforward application of empirical process theory, we show that S-estimators of multivariate location and covariance are asymptotically equivalent to a sum of independent vector and matrix valued random elements respectively. This provides an alternative proof of asymptotic normality of S-estimators and clearly explains the limiting covariance structure. It also leads to a relatively simple proof of asymptotic normality of the length of the shortest α-fraction.

University Students’ Attitudes Towards Entrepreneurship: A Two Countries Comparison

There is general agreement that attitudes towards the entrepreneur, entrepreneurial activity, and its social function are determinant factors for university students to decide an entrepreneurial career.This empirical study aims at assessing and comparing the attitudes of university students towards entrepreneurship and enterprise formation in Catalonia and Puerto Rico, using a sample of 837 and 435 students, respectively.Results reveal a positive entrepreneur’s image. Both samples have a favorable perception of desirability of new venture creation, although the perception of feasibility is by far not so positive and only a small percentage has the firm intention to create a new company.     

供应链中基于质量控制的契约模型分析

供应链中的业务外包策略充分发挥了供应链节点企业的核心竞争力，但同时存在产品质量难以控制的问题。本文通过构建以价格折扣和质保金为参数的契约模型，分析了制造商在非对称信息条件下对业务外包产品进行质量控制的最优契约设计问题。     

建筑工程无标底招标理论与实践

随着中国建筑业管理体制改革的不断深化，招投标制度在中国得以推广应用，但在招投标机制方面还存在不足，有待完善。文章通过无标底招投标的博弈论基础，分析了无标底招标的意义和作用，同时对无标底招标的实施提出了一些相应的措施和建议，最后指出，随着中国加入WTO，与国际接轨，推广无标底招投标方法是我国建筑业招投标制度改革的当务之急。
