Wavelet domain correlation between the futures prices of natural gas and oil

This paper studies the relationship between futures prices of natural gas and oil. Using wavelet analysis, our research reveals that, throughout the sampled period: (1) the prices of natural gas futures and oil futures have high covariance at high frequencies but not so much at low frequencies; (2) an increase in financialization of commodities commensurate with investors search for yield results in higher covariance between the futures prices of natural gas and oil; and (3) the volatility of neither time series consistently leads the other even at high frequencies.

Risk-neutral skewness and market returns: The role of institutional investor sentiment in the futures market

This paper investigates the effect of index risk-neutral skewness on subsequent market returns and explores whether this effect will vary with various types of institutional investor sentiment in the futures market. Using index futures returns as the proxy of market returns, the empirical results show that the index risk-neutral skewness has a significantly negative effect on subsequent index futures returns. Moreover, the effect of institutional investor sentiment on subsequent index futures returns varies with various types of institutional investor sentiment. Finally, the effect of index risk-neutral skewness on subsequent index futures returns relies on various types of institutional investor sentiment.     

The empirical relevance of the competitive storage model

The empirical relevance of models of competitive storage arbitrage in explaining commodity price behavior has been seriously challenged in a series of pathbreaking papers by [Deaton and Laroque, 1992], [Deaton and Laroque, 1995] and [Deaton and Laroque, 1996]. Here we address their major criticism, that the model is in general unable to explain the degree of serial correlation observed in the prices of twelve major commodities. First, we present a simple numerical version of their model which, contrary to Deaton and Laroque (1992), can generate the high levels of serial correlation observed in commodity prices, if it is parameterized to generate realistic levels of price variation. Then, after estimating the [Deaton and Laroque, 1995] and [Deaton and Laroque, 1996] model using their data set, model specification and econometric approach, we show that the use of a much finer grid to approximate the equilibrium price function yields quite different estimates for most commodities. Results are obtained for coffee, copper, jute, maize, palm oil, sugar and tin that support the specifications of the storage model with positive constant marginal storage cost and no deterioration as in Gustafson (1958a). Consumption demand has a low response to price and, except for sugar, stockouts are infrequent. The observed magnitudes of serial correlation of price match those implied by the estimated model.     

The macroeconomic response to real and financial factors,commodity prices,and monetary policy: International evidence

This study estimates a variety of small dynamic factor macro models where the factors are time-varying. The sample consists of 20 economies from around the world. Using quarterly data since the late 1990s, I find that the focus of some policymakers on the negative spillovers from monetary shocks is exaggerated. Four separate types of shocks are identified, and these can easily offset each other with a neutral to positive overall economic impact in some economies investigated here. However, a few economies, namely Brazil, Chile and China, experience a net economic loss from spillovers.

金属期货与现货市场价格互动关联规则挖掘研究

期货市场传递的价格信息反映未来供求状况的预期,因此,研究金属期货和现货市场价格互动,对于国民经济发展、企业规避价格风险、投资者进行投资决策及政府进行市场监管都有重要意义。本文将数据挖掘中的关联规则挖掘方法引入金融时间序列分析研究领域,针对挖掘对象期货市场的特点,提出基于时间约束的时间序列关联规则挖掘算法。与传统的忽视数据时间信息的关联规则挖掘算法相比,该算法对期货价格与现货价格间的互动关联规则进行挖掘,能发现反映时间序列局部动态互动关联关系,具有一定的短期预测效果。     

Residential investment and house prices in a multi-sector monetary business cycle model

This paper develops a three-sector quantitative dynamic stochastic general equilibrium model to account for some of the salient business cycle properties concerning residential investment and house prices. We depart from the traditional Real Business Cycle setup by incorporating monetary frictions and credit market activities into the model economy. The model generates the high volatility of residential investment and hours worked in the house investment goods producing sector, as well as the procyclicality of house prices. The lead-lag pattern of house investment also roughly conforms with the data. We find that monetary policy and nominal interest rates play a special role in the determination of house prices. Money shocks generate remarkably volatile residential investment and house prices.
