人民币汇率变动对广西出口商品价格影响研究--基于广西与东盟国家贸易数据

论文选取2005年1月-2013年10月的月度数据实证分析了人民币名义汇率变动对广西出口到东盟国家商品价格的传递效应。结果表明：人民币名义汇率对出口商品价格的传递不完全,广西出口商的市场竞争力较弱,省内企业生产成本对出口价格的影响较小,而东盟国家竞争价格对出口价格的影响非常大。     

The Industry Determinants of Exchange Rate Pass-Through into Canadian Producer Prices

This paper models and estimates exchange rate pass-through and its determinants in Canadian manufacturing industries. The paper predicts theoretically that the exchange rate pass-through should be between one and zero, where it is positively affected by the share of tradable inputs in production costs and the domestic firms’ market share, and negatively by the elasticity of marginal cost with respect to output. The sign for the degree of product differentiation is not theoretically clear. Results of estimation indicate that pass-through is incomplete and is mostly affected by the share of tradable inputs in production costs (positively) and the elasticity of marginal cost with respect to output (negatively).     

中国资产价格膨胀与日本泡沫经济的比较与启示

近年来,中国资产价格上涨已经引起了国内外广泛关注,这与日本泡沫经济前期的情况如出一辙。_良好的经济基本面、宽松的资金面和市场信心是推动中日两国资产价格上涨的共同因素。而中日两国长期实行出口导向型经济发展战略,依靠间接融资的金融体制,成为导致两国资产价格膨胀的深层次原因。与日本相比,中国资产价格膨胀可以在较大程度上化解,不会重蹈日本资产泡沫破灭的覆辙。但短时间内资产价格过快上涨,成为经济增长和金融稳定的潜在风险,为此,中国应该积极总结日本泡沫经济时期的经验教训,从日本政府的应对政策中得出重要的启示。     

Price transmission between products at different stages of manufacturing in forest industries

The theory of demand and supply implies a positive relationship, or “price transmission” between the prices of products at different stages of manufacturing. This relationship was investigated with quarterly prices of softwood stumpage in the US South, and national prices of forest products, from 1977 to 2002. All prices, net of inflation, were found to be nonstationary and there was no evidence of co-integration between prices. Vector autogressive models, augmented by Granger causality tests and multiplier analysis showed that there was a one-to-one permanent positive response of the southern sawtimber stumpage price to a permanent change in the national lumber price. There was also a one-third permanent positive response of the national paper price to a permanent change in the national pulp price. There was no relation between regional pulpwood prices and national pulp or paper prices. When price transmission was significant, the full adjustment took about 2 years.     

Trade mechanism selection in markets with frictions

We endogenize the trade mechanism in a search economy with many homogeneous sellers and many heterogeneous buyers of unobservable type. We study how heterogeneity and the traders' continuation values—which are endogenous—influence the sellers' choice of trade mechanism. Sellers trade off the probability of an immediate sale against the surplus expected from it, choosing whether to trade with everyone and how quickly. In equilibrium sellers may simply target one buyer type via non-negotiable offers (price posting), or may price discriminate (haggling). We also study when haggling generates trading delays. A price setting externality arises because of a strategic complementarity in the sellers' pricing choices.     

人民币汇率与我国股价、房价的联动关系研究

近年来,我国人民币汇率形成机制、股票市场和房地产市场发生了巨大变化,人民币汇率和股价、房价之间的信息传导和波动关联备受瞩目。本文采用VAR-MGARCH-BEKK模型,分析了我国人民币汇率、股价和房价之间的联动关系。研究结果表明,从波动的溢出效应来看,人民币汇率的波动率、股票价格的增长率和房地产价格的增长率之间存在非常明显的波动溢出效应;从资产价格的水平影响来看,人民币汇率与股票价格、房地产价格等国内资产价格的水平相关性较弱,而股票价格对房地产价格的影响较明显,并就该结论提出了相关的理论解释和政策建议。     

Biofuels and the poor: Global impact pathways of biofuels on agricultural markets

This study seeks to assess the future impacts of biofuel production on regional agricultural and related sectors over the next decade with a specific focus on the vulnerable regions of developing nations. Using a modification of the GTAP modeling platform to account for the global interactions of regional biofuel and food markets, the analysis shows that biofuel production levels depend on the assumption about the future price of energy and the nature of the substitutability between biofuels and petroleum-based transport fuels. Low energy prices reduce the demand for biofuels and thus require greater government support to meet the desired production targets. At the other extreme, when prices are high and there is scope for substituting biofuels for petroleum-based fuels, the volume of biofuels produced will exceed the mandates. Even when biofuels are being mainly produced in developed countries, our results indicate that there are impact pathways that extend far beyond the borders of the US, Brazil and the EU. Prices of feedstock and non-feedstock commodities rise in developing countries. There is also a rise in value added from the agricultural sector—a gain that is enjoyed by the owners of land and labor, including unskilled. Hence, to the extent that agriculture is a key sector in getting growth started and addressing poverty needs, the emergence of biofuels can (in this way at least) be a positive force.     

美元、石油和金属价格——基于VAR模型的实证研究

近年来,美元贬值以及石油价格上涨一直被认为是造成有色金属价格上涨的两个可能的原因。在这一背景下,笔者采用VAR模型分析了美元价值和石油价格变化对我国铜、黄金、白银等金属价格的冲击影响,以及在此冲击下三种金属价格间的相互影响关系。结果表明:美元价值以及黄金和白银二者之间的相互影响关系在很大程度上决定了我国黄金和白银的价格行为;而美元、石油、黄金以及白银价格的变化对于我国铜金属价格的冲击尽管是显著的,但是四者均不是铜金属价格上涨的主要原因。     

浅谈我国房地产政策——以房价的过快上涨所引发的思考

我国近些年来经济突飞猛进的发展,其背后房地产对CDP的拉动功不可没,特别在金融危机中,大幅拉动内需,成为我国实体经济的支柱产业,但随着需求增大,房价节节攀升,购房困难成为百姓实现小康生活的头号难题。本文就房价过高产生的原因,以及如何看待我国的房地产政策谈了几点看法,并针对高房价提出了几点对策建议。     

Why does the peso-dollar exchange rate show a depreciation trend? The role of productivity differentials

Over the last three decades, Mexico's macroeconomic policy has been driven by a sound orthodox strategy: an open economy via many trade agreements signed since the mid-1980s, a nominal exchange rate under a flexible regime since 1994, central bank autonomy, and responsible fiscal policy, among other benchmarks. Nevertheless, the exchange rate has continued on a path of depreciation against the US dollar. In this paper, we show that although an equilibrium relationship exists between the exchange rate and prices in Mexico and the US (its main commercial partner), there are other forces affecting the former. The main factor in this relentless long-term depreciation is the loss of productivity in Mexico relative to the US. In addition, we show that the extraordinary liquidity supplied by the US during the 2008 crisis caused the Mexican peso to appreciate against the dollar.
