Volatility returns with vengeance: Financial markets vs. commodities

To assess how financial markets and commodities are inter-related, this paper introduces a ‘volatility surprise’ component into the asymmetric DCC with one exogenous variable (ADCCX) framework. We develop an econometric model in which returns and volatility allow to influence pairs of assets, and derive several case studies linking commodities to stocks, bonds and currencies from 1983 to 2013. The innovative feature of our model is that these volatility spillovers are modeled consistently within the correlation dynamics of the ADCCX. We find evidence that return and volatility spillovers do exist between commodity and financial markets and that in turn, their relative impact on each other is very substantial.     

环境与就业维度下出口商品结构优化——以江苏为例

利用计量方法从环境和就业这两个指标来考察江苏出口商品结构优化,其中环境指标主要是通过碳排放指标来体现的。通过研究发现江苏九大类出口商品在环境和就业指标上都无此消彼长现象,其中对两指标都具显著影响力的为机械及运输设备,化学品及有关产品和按原料分类的制成品这两类出口商品仅对环境有着显著影响力,对就业不具显著影响力,至于其他种类的出口商品则对环境和就业这两个指标都不具显著影响力,最后得出江苏出口商品结构优化的最明确方向,即大力促进机械及运输设备的出口,抑制化学品及有关产品和按原料分类的制成品这两类出口商品的出口。     

Quantification of the high level of endogeneity and of structural regime shifts in commodity markets

We propose a “reflexivity” index that quantifies the relative importance of short-term endogeneity for several commodity futures markets (corn, oil, soybean, sugar, and wheat) and a benchmark equity futures market (E-mini S&P 500), from mid-2000s to October 2012. Our reflexivity index is defined as the average ratio of the number of price moves that are due to endogenous interactions to the total number of all price changes, which also include exogenous events. It is obtained by calibrating the Hawkes self-excited conditional Poisson model on time series of price changes. The Hawkes model accounts simultaneously for the co-existence and interplay between the exogenous impact of news and the endogenous mechanism by which past price changes may influence future price changes. Our robustness tests show that our index provides a ‘pure’ measure of endogeneity that is independent of the rate of activity, order size, volume or volatility. We find an overall increase of the reflexivity index since the mid-2000s to October 2012, which implies that at least 60–70 percent of commodity price changes are now due to self-generated activities rather than novel information, compared to 20–30 percent earlier. While our reflexivity index is defined on short-time windows (10–30 min) and thus does not capture long-term memory, we discover striking coincidence between its dynamics and that of the price hikes and abrupt falls that developed since 2006 and culminated in early 2009.     

高职院校《进出口商品归类》教学的探讨

近年来,高等职业技术教育蓬勃发展,加入W TO后,不少学校更希望以此为契机,大力发展国际经济与贸易专业的高职教育。《进出口商品归类》是高职院校国际经济与贸易专业中开设的专业技能类课程,也是一门实用性强的新课程,在教学实践中会不可避免地碰到一些问题,文章拟对此进行研究,提出个人见解,以促进国际经济与贸易高职教育的健康发展。     

论新疆特色旅游商品的深度开发

旅游商品的销售状况是反映一个国家与地区旅游发展水平的重要标志。挖掘地方和民族文化内涵,加强旅游商品的深度开发将有利于新疆旅游商品产业链的深化与延伸,对满足旅游者对旅游商品的多元化需求,促进新疆旅游业的发展,以及培育新疆经济新的增长点都有重要意义。     

人民币汇率变动对中国出口商品结构影响分析

本文运用2005～2007年季度数据对人民币汇率变动和出口商品结构变动进行实证分析后得出,人民币升值有助于劳动密集型和资本/技术密集型商品出口,且对劳动密集型商品促进力度弱于资本/技术密集型商品,但对资源密集型商品出口产生不利影响;笔者对其成因进行分析后得出中国可在一定条件下利用人民币升值实现出口商品结构的优化。     

Commodity markets through the business cycle

From 2008 to 2011, commodity markets experienced growing attention from the banking industry for various reasons: the summer 2008 oil price swing, the price surge in an ounce of gold, or sharp variations in agricultural prices. As a consequence, can we hypothesize the existence of a global connection between commodities and economic cycles? If these recent events suggest that commodity markets are strongly related to the business cycle, this evidence goes nevertheless against the widespread intuition that commodity markets are a strong source of diversification in a standard cash–bond–equity portfolio. Based on a data-set from 1990 to present, this paper investigates this issue by (i) looking at the reaction of commodity markets to economic news, and (ii) using a Markov regime-switching model to analyse economic regimes and commodity markets as an asset class.
