国土经济学的研究对象和理论基础

国土经济学是研究国土资源可持续利用同国民经济可持续发展关系的一门经济科学。我国人均资源占有量低于世界人均水平,加之长期对自然资源保护力度不够,实行粗放型经济增长方式,资源大量消费,生态环境日趋恶化,国土资源可持续利用面临严峻挑战。国土经济学的任务主要是研究国土资源的可持续利用与资源的优化配置。国土经济学理论基础有3个方面：自然资源财富观、资源可持续利用论与资源优化配置论。     

民族地区农村生产要素市场化的实证分析——以云南省丽江市玉龙县鲁甸乡为例

民族地区农村生产要素市场化水平比较低,阻碍了民族地区农村市场化改革的进程,并直接影响到农民增收。完善农村生产要素市场体系、理顺市场机制、实现生产要素的优化配置是农村市场化改革的关键。文章阐述了农村生产要素市场化改革的重要意义,分析了农村生产要素市场化的制约因素,并以云南省丽江市玉龙县鲁甸乡的实践为例,试图为农村生产要素市场化改革提供启示。     

基于信息经济学视角的品牌资产生成研究

目前，国内外品牌资产的研究大都从企业或消费者单一角度出发，对品牌资产概念和外延体系及其品牌资产管理模式等方面进行研究，对品牌资产生成的研究甚为罕见。本文从信息经济学中信号理论的观点出发，对在品牌资产生成中信息传递的特殊作用、传递机理以及品牌资产生成路径进行了系统的分析，并首次提出只有建立企业与消费者的互动关系，企业与消费者才能最有效地传递和解读双方所发出的品牌信号，使得品牌信号的信息含量最充分地在企业和消费者之间传递，从而使品牌资产得以生成并在不断演进中增值。     

Sustaining Collusion Via a Fuzzy Trigger

Probability theory is the standard economic representation of uncertainty, although it is not always an accurate one. Fuzzy logic is an alternative representation that does not require individual beliefs regarding the explicit functional form of uncertainty. This paper applies fuzzy logic to an oligopoly trigger pricing game. The fuzzy trigger pricing game reverses the standard cyclical price war prediction; collusion-sustaining price wars are most likely to occur during times of high demand. The fuzzy model also predicts that markets with relatively volatile prices are more likely to undergo collusion-sustaining price wars. The predictions are consistent with available empirical evidence.     

TOWARD BRIDGING THE GAP BETWEEN THEORY AND EMPIRICAL REALITY

Introductory (i.e. first year) undergraduate learners often perceive economics to be remote from reality and overly theoretical, leading to a lack of motivation and enthusiasm to study economics. A general survey of curriculum practice reveals that lecture materials and the pedagogic approach to teaching introductory economics often do not place the current “mainstream” economic theory into its philosophical context. The result being that the learners are unable to bridge the gap between abstract economic theory and empirical reality. This paper argues that research into effective teaching and learning should focus not only on learner characteristics but also on curriculum content and its philosophical underpinnings, in order to research why students hold these negative perceptions. The paper recommends that introductory undergraduate teaching needs to engage in a critical examination, with the learner, of the philosophical underpinnings of “mainstream” economic theory and to introduce debates about the implications of these into the curriculum. This would create exciting new opportunities for teachers and learners to explore the connections between economic theory and social science in general and should come a long way in changing the negative perceptions of introductory undergraduate economics.     

Waves and Determinants in Mergers and Acquisitions: The Case of Latin America

This article contributes to the current literature on mergers and acquisitions (M&As) by identifying the existence of waves and the determinants of M&A activity in the economies of Argentina, Brazil, Chile, Colombia, Mexico, and Peru. From a sample of 2,391 M&A announcements reported by Thomson One on these countries, applying the methodology proposed by Harford (2005), evidence of M&A waves is found for the periods 1995–2002 and 2003–2010, as reported for other regions in various international studies. After controlling for economic and business environment variables, as well as for profitability and book-to-market variables at the industry level, we find evidence that supports neoclassical theory as a main explanation for M&A activity but not for the misvaluation effect.     

The Impact of Farmland Transfers on Agricultural Investment in China: A Perspective of Transaction Cost Economics

There is growing concern that farmland transfers lead to less agricultural investment, which may adversely affect agricultural productivity growth in China. Prior research has primarily focused on the differences between owned cultivated land and rented plots, but little is known about how farmland transfers between relatives, which are popular in rural China, specifically affect agricultural investment. In this paper, we present a conceptual framework of transaction cost economics to compare different contracting strategies in China's farmland rental markets. As farmland rental markets in China are immature, land transfer between relatives establishes bilateral governance, which has the advantage of addressing the opportunistic activities of both parties and can ultimately increase investment by tenants. Based on data from two waves of household surveys, we empirically examine the impact of bilateral governance on the application of organic fertilizer, an indicator for agricultural investment. Our findings show that apart from economic factors, kinship is important to the functioning of farmland rental markets in rural areas.     

论我国西部区域间经济发展格局的变动

西部大开发的10年中,西部各地区都取得了巨大的发展成就,但彼此间的发展进度并不一致,导致了经济发展格局的变动。经过数据分析发现,西部各区域间发展差距有扩大的趋势,并且经济发展重心也有较大变化。认真分析这一变化,对于因地制宜的制定区域发展政策,促进区域协调发展具有重要指导意义。     

复杂视域中的适应性效率与后危机时代的经济发展

全球金融危机凸显出经济的复杂性本质,人们终于认识到"适应性效率"而非"资源配置效率"才是长期经济增长的关键。基于复杂性思想,本文系统梳理了诺思适应性效率理论并弥补了其不足,并据此对后危机时代的经济发展提出了对策。     

商业年金消费决策的行为经济学分析

商业年金是我国养老保险体系的重要组成部分,虽然近年来我国在政策层面不断推动商业年金的发展,但是我国居民的商业年金需求仍然十分低,存在“年金谜题”现象。本文从行为经济学的视角展开对商业年金消费决策的分析,首先从理论层面阐述了行为因素对商业年金消费决策的影响机制,随后设计调查问卷收集个体数据,从实证层面进行了验证。结果发现,主观概率、心理账户、信息感知、金融素养等行为因素会显著影响个人的商业年金消费水平,其他客观因素如性别、年龄、婚姻状况、风险态度以及收入水平等也会显著影响个人的商业年金消费水平。基于本文研究结果,认为未来商业年金回归保障属性、弱化个人账户概念以及发展保险咨询服务等可以带来商业年金需求的提升。
