Let me sleep on it: Delay reduces rejection rates in ultimatum games

Delaying acceptance decisions in the Ultimatum Game drastically increases acceptance of low offers. While in treatments without delay less than 20% of low offers are accepted, 60-80% are accepted as we delay the acceptance decision by around 10 min.     

On negative time preferences

Survey data show that subjects positively discount both gains and losses but discount gains more heavily than losses. This holds for monetary and non-monetary outcomes. These results do not confirm the findings of two earlier studies about negative time preferences for non-monetary outcomes.     

90后大学生对社会主义核心价值体系的认同及引导——以湖南科技学院为例

大学生是与国家的改革、稳定和发展,前途和命运息息相关。当前,90后大学生已经成为高校中绝对主力军。从笔者的调查结果来看,90后大学生对社会主义核心价值体系的认同,主观意识差强人意,但客观现状却令人堪忧。社会主义核心价值体系在＂主渠道＂、＂主阵地＂都出现＂失语＂状态。当前高校的社会主义核心价值观体系引导教育需要更新教育观念、拓展教育内容、重视教育方法。总之,促进90后大学生形成对社会主义核心价值体系的确信是一项意义极为深远的重要工作。     

整合协同效应视角下网络型产业并购绩效研究——来自信息技术业的经验证据

以信息技术业为例,采用事件研究与因子分析模型对网络型产业企业并购的市场投资者预期绩效与经营绩效分别进行探讨.研究发现,中国证券市场存在信息非半强式有效;市场对网络型产业不同类型的并购均持较为肯定的态度,市场投资者预期绩效改善明显;企业关联度对企业并购经营绩效作用较大,横向和纵向并购绩效改善显著,混合并购很难提高甚至有可...     

合并商誉减值测试计量的比较研究

财政部新颁布的《企业会计准则第8号——资产减值》,首次对合并商誉的减值测试作出了相关的规定。合并商誉减值的计量取决于三个关键因素:减值测试的测试单元、减值测试的计量基础以及减值测试的测试方法。本文拟结合合并商誉的特点,将我国准则与国际会计准则委员会以及美国关于这方面的相关规定进行比较,并提出我们的建议。     

Consumption choice and asset pricing with a non-price-taking agent

Summary. This paper develops a pure-exchange model to study the consumption-portfolio problem of an agent who acts as a non-price-taker, and to analyze the implications of his behavior on equilibrium security prices. The non-price-taker is modeled as a price leader in all markets; his price impact is then recast as a dependence of the Arrow-Debreu prices on his consumption, allowing a tractable formulation. Besides the aggregate consumption, the endowment of the non-price-taker appears as an additional factor in driving equilibrium allocations and prices. Comparisons of equilibria between a price-taking and a non-price-taking economy are carried out. Received: March 29, 1996; revised version October 29, 1996     

Necessity of transversality conditions for stochastic problems

This paper shows stochastic versions of (i) Michel's (Econometrica 58 (1990) 705, Theorem 1) necessity result, (ii) a generalization of the TVC results of Weitzman (Management Sci. 19 (1973) 783) and Ekeland and Scheinkman (Math. Oper. Res. 11 (1986) 216), and (iii) Kamihigashi's (Econometrica 69 (2001) 995, Theorem 3.4) result, which is useful particularly in the case of homogeneous returns. These stochastic extensions are established for an extremely general stochastic reduced-form model that assumes neither differentiability nor continuity.     

To be consumed with moderation

We study the optimal behavior of a hyperbolic discounting agent who has incomplete information about his own preferences and can only learn them through consumption. We show that, even if moderate current consumption and moderate future consumption always dominates abstinence, the agent may optimally decide not to consume as a commitment device against inefficient learning that would lead to future excesses. This provides a rationale for why smokers, gamblers or compulsive buyers stick to second-best personal rules of behavior - such as “abstinence” - without invoking standard habit formation arguments. We also study how urges modify the strategy of the individual.     

Economic integration and agglomeration in a middle product economy

We examine the interactions between economic integration and employment agglomeration in a neoclassical-growth, middle-product economy. There are two vertically integrated economies, with competitive final good firms operating plants in both regions and monopolistically-competitive intermediate good firms operating each in only one region. Immobile workers are employed with traded middle products to produce the nontraded final good; mobile workers are used with immobile capital to design and produce differentiated intermediate good inputs. While agglomeration and growth need not be positively related, trade need not enhance regional growth nor widen the skilled-unskilled wage gap.     

Recursive preferences and balanced growth

We study a class of utility functions that are defined recursively by an aggregator W(x,y) where u_t=W(c_t,u_t+1). In single-agent economies it is known that a sufficient condition for the existence of a balanced growth path is that utility should be homogenous of degree γ. In the context of a multi-agent economy we show that this restriction implies that either a balanced growth equilibrium fails to exist or all agents have the same constant discount factor. We suggest a generalization of recursive preferences wherein the intertemporal utility function is time dependent. Within this class we establish that there may exist a balanced growth equilibrium even if agents are different.
