闲暇经济理论综述及最新进展

随着国外发达国家相继进入后工业化社会,闲暇经济理论尽管还远未成型,但已经成为国外经济研究的新兴课题,本文按照闲暇经济理论的发展历史和研究方向,从两个方向综述了该理论的内容,一是依据对不同类型闲暇时间的研究来进行综述,二是在此基础上从闲暇被引入进各类函数和经济系统的角度综述了相关研究的主要成果.     

Modelling international tourism and country risk spillovers for Cyprus and Malta

Small Island Tourism Economies (SITEs) are developing sovereign countries that rely on tourism as a source of exports, and need a consistent inflow of foreign investment in order to facilitate economic growth. Access to international capital markets helps SITEs smooth out their consumption over time, while absorbing adverse domestic production shocks. This paper provides a comparison of tourism growth, country risk returns and their associated volatilities (or uncertainty) for 2 SITEs, namely Cyprus and Malta. Monthly data are available for both international tourist arrivals and composite country risk ratings compiled by the International Country Risk Guide (ICRG) for the period May 1986 to May 2002. The time-varying conditional variances of tourism growth and country risk returns for the 2 SITEs are analysed using multivariate models of conditional volatility. Empirical results show that Cyprus and Malta are complementary destinations for international tourists. Changes to tourism patterns in Cyprus lead to changes to tourism patterns in Malta. Hence, tour operators and national tourism promotion authorities in Cyprus and Malta should collaborate closely in marketing and promoting joint tourism products. Moreover, foreign entities interested in investing in the tourism sectors of Cyprus and Malta should consider investment projects that span a long period of time. The performance of the tourism sector and the associated composite risk are independent of each other for the two countries. However, there is a direct relationship between the tourism sectors of Cyprus and Malta and their respective country risk settings.     

安全标准与农产品贸易:中国与主要贸易伙伴的实证研究

国际农产品贸易引起争端的安全标准的大量存在,表明市场自身力量不足以纠正失灵,农产品市场的独有特征构成安全标准广泛实施的理由。文章测算了十年间一项具体农产品安全标准—黄曲霉素最大允许含量标准,对一组发达国家和一组包括中国在内的亚洲发展中国家的水果/坚果类产品的贸易影响程度。政策模拟结果显示,进口国协调采用国际标准将产生更大的贸易促进效果。     

货币供给、通货膨胀和粮食价格波动互动关系研究

在VAR模型和方差分解基础上,利用1997年以来的月度数据,分析货币供应量、通货膨胀和粮食价格之间的关系。结果显示：通货膨胀对粮食价格有显著影响,存在货币供应量、通货膨胀到粮食价格变动这一传导途径,同时发现通货膨胀有较强的自身惯性,通过抑制粮食价格来控制通货膨胀是无效的。     

Evolution and challenges of dairy supply chains: Evidence from supermarkets,industries and consumers in Ethiopia

In developing countries the demand for products of animal origin is expected to grow rapidly in the coming years. Using data collected from 200 urban households this study examines the evolution of the dairy market in Ethiopia. In particular, this study suggests that although the Ethiopian dairy market remains extremely thin and volatile, the commercialization of processed dairy products through supermarkets is expanding and is expected to keep doing so in the foreseeable future. Increasing urbanization and corresponding changes in consumer preferences, behaviour and purchasing power are the identified causes for the rise of supermarket-processor dairy chains. This study shows also that emerging dairy chains provide new market opportunities to Ethiopian farmers, but the existence of retail-industrial monopolies and monopsonies jeopardize farmers’ economic benefits to a great extent. The study concludes with some implications for policy and further research.

动态能力核心构成及其功效模型探究

动态能力是一种新的战略分析框架。研究人员和经理人的一个根本问题是理解动态能力,即重新配置资源以应对动荡环境的经营能力。动态能力一直被视为抽象。动态能力的三大核心构成要素分别是学习与吸收能力、协调整合能力与创新能力。

Twists and turns of triadic business relationship recovery

This study focuses on triadic business relationship recovery processes through a single case study. We address the question of what kind of process takes place when a business relationship on the verge of ending is recovered and what roles a third actor can play in the process. As a result, we model a process through which a triadic business relationship is recovered and attraction, trust, and commitment are restored.     

金融发展、制度演进与经济增长

根据内生增长理论,确定经济增长的影响因子,然后着重考察制度因素,将其与金融发展的指标变量建立回归模型,以此深入分析金融发展作用于经济增长的制度演进渠道。研究结果表明：无论在长期还是短期内．金融发展对制度演进的影响较大;并且金融中介对制度演进的作用明显要大于金融市场。
