Openness to trade as a determinant of the macroeconomic elasticity of substitution

Several theoretical and empirical studies on economic growth consider the macroeconomic elasticity of substitution between capital and labor as a measure of economic flexibility that depends on technological as well as institutional aspects. One institutional aspect of economic flexibility is openness to trade. I examine in a Heckscher–Ohlin model with two large countries trading intermediate goods how openness affects the elasticity of substitution. If the technology has a constant elasticity of substitution in a closed economy, opening up to trade raises the elasticity of substitution only in the country that accumulates capital at a faster rate.     

国际购买力平价和简化净出口函数:中国实证

文章从国际交换价值的角度研究了一价定律的内涵,提出了国际购买力平价理论,并且证明了国际购买力平价是严格意义上的均衡汇率。2009年人民币贸易品购买力平价为6.70元人民币/美元,而国际购买力为5.49元人民币/美元,后者可作为确定人民币汇率处于均衡水平的参考。文章还简化了净出口函数,得出如下主要结论:(1)近年我国的贸易顺差大幅增长,主要是因为价格贸易条件恶化,其次是因为J曲线效应;(2)当前的首要任务是改善我国的价格贸易条件以提高国际购买力平价,而不是调整人民币汇率。     

Access to Finance,Financial Development and Firm Ability to Export: Experience from Asia–Pacific Countries

With particular reference to Asia–Pacific countries, the present study examines how access to finance and financial development affects firms’ ability to enter export markets. Using firm‐level data from the World Bank Enterprises Survey, we found that access to finance plays a significant role in improving firms’ ability to export. In addition, development of the financial sector fosters export market entry. Among the financial development indicators, reach of the banking sector variable is most prominent. The present study suggests that improvements in access to finance and financial development (increases in the reach of the banking sector) enable firms operating away from capital or major cities to enter export markets easily. The present study supports policy intervention to strengthen access to the financial sector, which would encourage firms to export, and to facilitate export market entry for remotely located firms.

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。     

我国金融发展对国际贸易的影响及区域差异——基于跨省面板数据的协整分析和广义矩估计

本文针对有关我国金融发展影响国际贸易的现有研究只重视国家层面、忽视区域差异的事实,基于跨省面板数据,运用面板协整理论和广义矩估计方法,不仅就全国整体,更深入东、中、西部区域内部实证分析了我国金融发展对国际贸易影响的长期均衡和短期动态影响。结果表明:无论是在长期,还是在短期,全国金融发展对进、出口都有着显著的促进作用,但在不同区域,其影响差异显著。其中,东部地区金融发展对进出口的长期促进作用明显大于中、西部地区;而短期内,虽然东部金融发展促进了进出口,但中、西部金融发展却不同程度地制约了进出口的发展。     

Migration Flows and Intra-Industry Trade Adjustments

In this paper we analyse the link between trade and migration. Focusing on the experience of Spain, we relate a marginal index of intra-industry trade to the stock of foreign workers—classified according to their country of origin and their situation in the Spanish labour market. We focus on the possibility that existing networks of foreign workers and their connections with their countries of origin could stimulate trade with the host country. Our results show a significant impact of the number of immigrants with work permits on intra-industry trade adjustment. However, this impact being positive or negative depends on whether foreign workers are employees or self-employed, the duration of the work permits and the type of job they occupy. JEL no.
