Exchange rate sensitivity of US bilateral trade flows

The traditional way of assessing the impact of currency depreciation on the trade balance has been to estimate the elasticity of trade volume to relative prices. To this end, most previous studies used aggregate trade data. To avoid aggregation biases potentially hidden in aggregate data, recent studies have relied on bilateral trade data. Since import and export price data is not available on bilateral level, this study proposes an alternative way of assessing the impact of currency depreciation on bilateral trade flows. The models are applied between the US and her 19 industrial trading partners using recent advances in time-series modeling.

标准化对我国出口贸易的影响

在标准主导国际竞争的时代,标准化已成为影响国际贸易的重要变量.本文选取1991-2010年的样本数据,在利用单位根检验对变量平稳性考察的基础上,采用协整检验方法对我国国家标准增量、外商直接投资额、人民币汇率和我国出口贸易额等变量的长期均衡进行了分析并作了误差修正和Granger因果检验.结果表明,外商直接投资额和人民币汇率与我国出口贸易存在正相关,而我国国家标准增量在短期内对我国出口贸易具有抑制作用,在长期内则对我国出口贸易具有促进作用.     

中国式的财政分权与宏观经济绩效——财政分权的宏观收益与成本分析

本文首先指出国外关于财政分权对于经济增长和通货膨胀的作用机制在中国不适用,然后提出了中国的财政分权对于经济增长和通货膨胀特有的作用机制,并且用协整检验方法实证的研究了1980-2005年间中国的财政分权对于济增长和通货膨胀的作用,得出财政分权改革以来中国式的财政分权在促进了经济增长的同时,也加剧了通货膨胀.     

欧盟REACH法令对中国化工产品出口的影响分析

欧盟REACH法令的实施将促进我国化学工业的发展,但在短期内会导致我国出口欧盟化工产品和进口化工产品成本上升,降低出口产品竞争力,部分产品甚至退出欧盟市场,其他国家可能纷纷效仿欧盟,引起连锁反应。应对该种技术性壁垒,我国政府和行业协会应加大宣传REACH法令的力度,加快国内相关立法,推进国内实验室的GLP认证工作。另外,化学品生产企业应提高自身产品质量,做好化学品注册的可行性分析和预注册工作。

The contribution of implicit cognition to the Theory of Reasoned Action Model: a study of food preferences

Abstract

Attitudes are at the heart of the Theory of Reasoned Action (TRA), but problems in defining and measuring attitudes have contributed to typically low ability to predict behaviour. This article investigates the impact of potential disjuncture between evaluations that an individual externally verbalises (explicit attitudes), and evaluations that are internally held and may exist outside of conscious awareness (implicit attitudes), on the predictive ability of TRA. We study consumers’ attitudes towards eating healthy food and subsequent behaviour in a context of socially consensual behaviour. An Implicit Association Test (IAT) is used to measure implicit attitudes, and these scores are contrasted with self-reported explicit attitude scores. Ninety one participants took part in the study. We found, surprisingly, that implicit attitude has no significant effect on behavioural intention. However, a disjuncture between an individual’s implicit and explicit attitudes, reflecting internal psychological conflict, affected behaviour.

Do Vietnamese upland farmers benefit from high world market prices for maize?

For rural households in the north of Vietnam, maize cropping is the main source of income. In the face of the world market price increases of the recent past, we analyze the regional marketing chain of this commodity qualitatively and econometrically investigating to what extent smallholder farmers in developing countries are affected by international price movements. Vietnamese maize markets are found to be well integrated. Recent price hikes have fully transmitted along the regional supply chain so that farmers profited. Nevertheless, adverse factors such as increasing input prices have neutralized these benefits resulting in a decline in real income of smallholders.
