对偶性一般均衡分析与国际贸易理论的深化-基于迪克西特与诺曼著《国际贸易理论》的分析

该文以迪克西特与诺曼合著的《国际贸易理论》一书为参照,分析了现代贸易理论所面临的三种挑战,探讨了对偶性一般均衡分析方法在应对这些实践挑战与深化国际贸易理论的比较优势,并且揭示了对偶性一般均衡分析方法由一种特殊的分析技术成长为国际贸易研究中的主流分析范式的过程与原因.

THE STRATEGIC ROLE OF INTERNATIONAL CREDIT AS AN INSTRUMENT OF TRADE*

This paper is an investigation of the role of international credit as a factor influencing the donor Countries' exports. Based on standard techniques of microeconomic theory, our model examines this relationship under different market structures in the industrialized donor country (North). Under monopoly and perfect competition, the availability of credit increases the North's exports; under oligopoly, within a class of parametric configurations, this relationship is reversed. We also find that, under certain conditions, if a developing country (South) takes recourse to international credit to finance its imports, it would end up worse off, that is the availability of international credit can be welfare-decreasing for the borrowing nation.     

外贸对经济增长的影响分析:理论与经验模型验证

国际贸易理论的核心问题是探究贸易利益的产生及其分配,国际贸易与经济增长具有密切联系。理论分析和经验证据均表明,一国外贸规模对经济增长有着重要作用,对外贸易的变动往往成为决定一国经济增长趋势的关键因素。文章从理论和经验模型上对我国近10多年来外贸和经济增长的关系给出了相关的实证检验,旨在探讨并揭示国际贸易促进经济增长的内在机制。     

INTERNATIONAL CAPITAL MOBILITY AND TRADE POLITICS: CAPITAL FLOWS, POLITICAL COALITIONS, AND LOBBYING

Conventional wisdom holds that increasing international capital mobility reduces incentives for firms to lobby for trade protection. This paper argues that the effects of increased international capital mobility on the lobbying incentives of firms depend critically upon levels of inter-industry mobility. General-equilibrium analysis reveals that if capital is highly industry-specific, greater international mobility among some types of specific capital may increase lobbying incentives for owners of other specific factors and thereby intensify industry-based rent-seeking in trade politics. Evidence on levels of inward and outward investment in US manufacturing industries between 1982 and 1996, and on industry lobbying activities, indicate that these effects may be quite strong.     

国际贸易结算币种内生选择机制研究——兼论人民币国际结算前景

本文从出口商期望利润最大化视角出发,梳理出一个国际贸易结算币种选择的微观分析框架。研究结果表明,在满足政治经济稳定性、货币的可兑换性、外汇市场的发达程度等前提条件下,需求价格弹性大小、汇率的波动性是影响结算币种选择的关键因素。     

短期国际资本流动对我国经济潜在冲击的实证分析

短期国际资本的流动会扰乱一国经济或金融市场的稳定。本文基于我国1997年1月—2009年9月的月度数据,根据赤池信息准则与施瓦茨信息准则,采用泊松相关系数,对VAR试算取得变量间或有影响机制,并根据测算结果对相关宏观经济指标做OLS回归分析。结果表明,短期国际资本的流动增大了中国证券市场的波动性,而对M2,CPI和ER等指标影响并不显著。本文最后根据结论对当前短期资本流动监管提出几点建议。     

企业产品最优品种数量确定及其生产方式的历史考察

本文分析的结论是:当产品品种数量的变化所引起的顾客满意指数的变化率与其所引起的顾客价值(未经顾客满意指数修正)变化率相等时,企业所创造的顾客满意价值(修正后的)最大.本文最后以汽车产业发展为例,考察了企业生产方式的演进历史。     

国际商品价格波动与中国出口贸易的能源成本:一个实证分析

中国的出口贸易面临着国际市场能源价格快速上涨与工业品价格滞涨的双重压力。本文对2002—2007年中国出口商品所包含的能源成本进行的估算发现,以2002年不变价计算的能源成本在5年间增长了7.53倍。与此对应,能源成本在中国出口总额中所占的比例从2002年的8.4%上升到了2007年的21.2%。通过计算价格弹性发现,国际市场上能源相对价格的波动是引起我国能源成本率上升的主要因素。能源成本快速上升大大降低了我国出口商品的利润空间,表明我国的外贸质量在下降,这主要是由国际市场进出口价格体系以及我国出口商品结构不合理所造成的。     

THE IMPACT OF TRADE AND INVESTMENT AGREEMENTS ON AUSTRALIA'S INWARD FDI FLOWS

International trade and investment agreements are one of the primary instruments of global financial liberalisation. They are enacted to enhance the flows of foreign direct investment (FDI) between signatories by reducing regulatory barriers to investment; promoting stable host investment environments; and guaranteeing investors against non‐commercial risk. As a net capital importer, Australia has sought to attract FDI through participation in such accords since the early 1980s. This paper examines the determinants of Australia's inward FDI flows—focussing specifically on the effects of trade and investment agreements. Using panel data, we find that both bilateral trade and bilateral and multilateral investment agreements attract FDI flows into Australia, thereby indicating that the policy of enticing FDI through participation in these accords is quite possibly effective.     

CURRENCY UNIONS, TRADE FLOWS AND CAPITAL FLOWS

Abstract.  Trade within currency unions is much larger than outside of currency unions, even after factoring in many relevant variables. The existing empirical evidence is based on reduced form models of trade, and therefore indicates correlation between but neither causality nor mechanism. This paper argues that the causal relationship runs from currency unions to trade, and then considers two possible mechanisms behind this: currency union membership: reduces trade resistance or reduces investment resistance. We argue that both mechanisms are required to explain the observed economic impact of currency union membership.
