A framework to facilitate institutional arrangements for smallholder supply in developing countries: An agribusiness perspective

The industrialization of agriculture and the potential problem of small-scale farmer marginalization calls for a fresh approach to the design of agribusiness supply chain arrangements in developing countries. The objective of the paper is to contribute to a better understanding of institutional arrangements that can promote stable smallholder agribusiness contracting arrangements in a developing country context. A case study approach, incorporating a transaction cost framework, is used to test whether trust can significantly change the contract characteristics of supply. The results suggest that although the presence of trust can influence the contract characteristics of a supply arrangement, it may not be significant because of other factors in a developing country context. Bearing this in mind, a number of institutional arrangements are recommended in order to promote more stable contract conditions.     

地方公共服务、要素流动与要素空间配置——基于本地交易成本的均衡分析

通过"两区域、两要素与两部门"模型研究发现,即使存在区域内与区域间两类交易成本,增加公共服务仍有利于吸引要素流入,并产生要素空间聚集效应;增加公共支出以改善区内贸易条件对要素流动及其空间分布具有不同的影响;我国地方公共支出规模与全要素生产率之间存在明显的长期因果关系.     

基金会计理论与我国政府会计改革

我国传统预算会计的基本目标是为了满足国家宏观经济管理对会计信息的需求,而未来的政府会计既要为政府制定政策、进行绩效评估提供信息,同时更要为纳税人提供有关整个政府财务的信息。因此,未来我国传统的预算会计模式需要借鉴国外经验,向政府会计模式转变。而要建立政府会计模式,必须明确基金会计的改革取向,推动我国政府会计的全面改革。     

Why are African commodity exchanges languishing? A case study of the Zambian Agricultural Commodity Exchange

Food price volatility and high transactions costs remain major problems in African food markets. These persistent problems provide a strong theoretical justification for the development of commodity exchanges. However, the majority of African commodity exchanges remain underdeveloped. Through a case study of the Zambian Agricultural Commodity Exchange (ZAMACE), this article explores why agricultural commodity exchanges in the region have thus far failed to develop into sustainable trading platforms and identifies the most important changes needed to enhance their performance.     

城市交通问题的产权分析

通过对多个城市的观察,发现《中华人民共和国道路交通安全法》的许多条款形同虚设,得不到切实的执行。本文根据产权理论对这一现象进行了分析,解释当前城市交通问题的主要成因即：车辆的增多、无法识别、十字路口和交通意识。产权的主要作用是帮助人们形成与他人交流的信息的预期,有了清晰界定的产权,就可以减少城市交通中人与人之间的不确定性,减小冲突的发生。为此,本文提出了解决城市交通问题的政策建议,即限制行车数量、增强非机动车辆的识别能力和规范十字路口标识,提高公民城市交通意识。通过减少交易成本,清晰的界定产权等手段规范城市交通,从而帮助行人建立稳定的预期,保证道路畅通。     

投资者异质性与证券市场定价——理论模型与中国的经验证据

本文从投资者异质性的客观现实出发,通过对投资者二维视角的交叉分类与相关行为的探讨,提出了一种按交易特点与行为依据的新的分类方案,即将投资者分为套利交易者、价格预期交易者和量能变动交易者三类。在此基础上分别建立了各类投资者的需求函数,通过对证券市场供求函数的讨论,利用均衡分析方法构建了基于投资者异质性的证券市场定价模型,并以我国证券市场1999-2011年的月度数据为样本进行了实证分析。实证结果表明:我国证券市场价格主要由价格预期交易者的诱导性策略行为与量能变动交易者的羊群行为决定,套利交易者的套利行为对市场价格没有显著的影响,证券市场扩容也未对市场价格的形成产生系统性冲击。

金融安全视角下的股市平准基金探析

通过平准基金的方式来平抑股价波动理论界历来存有争议。然而,宏观环境的变化、资本市场自身的体制机制性缺陷,将进一步增加我国金融体系的不确定性,强化金融内在的脆弱性,从资本市场的渠道对我国金融安全构成潜在的威胁和挑战。作为现代市场经济的核心,金融的稳定与安全高于一切,金融安全比市场化规则更重要。因此,规划设立股市平准基金,建立资本市场危机干预机制符合国家金融安全这一战略利益。当然,对于平准基金的管理、运作、风险控制和信息披露等方面应该制订一系列严格的制度规范,以控制基金自身的风险,保证基金的运行效率。     

Regional and Global Responses to the Asian Crisis

This paper examines how economic policy-making changed as a result of the Asian crisis of 1997–1998, in the countries affected, in the region, and at the global level. It is perhaps surprising how little change has occurred in the broad approach to economic policy, but there is a much greater awareness of the vulnerabilities posed by large international capital flows. The broad tenets of the Washington Consensus, with its market-based policies, remain in place, but there is a recognition that well-functioning markets require complex institutions, rules, and procedures, and that these take time and effort to develop. Most of this institutional development will have to take place at the national level, but regional arrangements can offer support, and multilateral agencies, such as the International Monetary Fund, have learned from the crisis.
