Measuring and testing Granger causality over the spectrum: An application to European production expectation surveys

Decomposing Granger causality over the spectrum allows us to disentangle potentially different Granger causality relationships over different frequencies. This may yield new and complementary insights compared to traditional versions of Granger causality. In this paper, we compare two existing approaches in the frequency domain, proposed originally by Pierce [Pierce, D. A. (1979). R-squared measures for time series. Journal of the American Statistical Association, 74, 901–910] and Geweke [Geweke, J. (1982). Measurement of linear dependence and feedback between multiple time series. Journal of the American Statistical Association, 77, 304–324], and introduce a new testing procedure for the Pierce spectral Granger causality measure. To provide insights into the relative performance of this test, we study its power properties by means of Monte Carlo simulations. In addition, we apply the methodology in the context of the predictive value of the European production expectation surveys. This predictive content is found to vary widely with the frequency considered, illustrating the usefulness of not restricting oneself to a single overall test statistic.

中国土地出让金与GDP关系研究

研究目的:揭示土地出让金与GDP之间的作用性质和作用程度。研究方法:Granger因果检验,广义脉冲响应和方差分解分析。研究结果:Granger检验结果显示土地出让金收入对GDP存在单向的显著可信的Granger因果关系,广义脉冲响应和方差分解结果显示,土地出让金对GDP的影响大于GDP对土地出让金的影响。研究结论:土地出让金对GDP有着显著的单向作用,GDP对土地出让金有较强的依赖性;而经济波动对土地出让金的影响不明显。     

河南省区域物流与GDP增长的协整与因果关系分析

对河南省1978～2006年区域物流与GDP增长进行了协整分析与因果关系检验。研究结论表明,河南省区域物流与GDP之间存在着长期的稳定关系,GDP的变化是引起区域物流变化的原因,且GDP对区域物流的长期正向拉动更为显著。     

Inflation forecasts and core inflation measures: Where is the information on future inflation?

This paper uses the forecast from a random walk model of inflation as a benchmark to test and compare the forecast performance of several alternatives of future inflation, including the Greenbook forecast by the Fed staff, the Survey of Professional Forecasters median forecast, CPI inflation minus food and energy, CPI weighted median inflation, and CPI trimmed mean inflation. The Greenbook forecast was found in previous literature to be a better forecast than other private sector forecasts. Our results indicate that both the Greenbook and the Survey of Professional Forecasters median forecasts of inflation and core inflation measures may contain better information than forecasts from a random walk model. The Greenbook's superiority appears to have declined against other forecasts and core inflation measures.

Income inequality and the business cycle: A threshold cointegration approach

This paper investigates the impact of various socio-economic variables on various cohorts of the income distribution. We use asymmetric cointegration tests to show that unemployment and immigration shocks have real impacts on income inequality. In addition, using threshold test results we are able to show that positive and negative shocks to the economy do not have symmetric effects nor do the impacts of these shocks impact income quintiles uniformly.     

Accuracy, unbiasedness and efficiency of professional macroeconomic forecasts: An empirical comparison for the G7

In this paper, we use survey data to analyze the accuracy, unbiasedness and efficiency of professional macroeconomic forecasts. We analyze a large panel of individual forecasts that has not previously been analyzed in the literature. We provide evidence on the properties of forecasts for all G7-countries and for four different macroeconomic variables. Our results show a high degree of dispersion of forecast accuracy across forecasters. We also find that there are large differences in the performances of forecasters, not only across countries but also across different macroeconomic variables. In general, the forecasts tend to be biased in situations where the forecasters have to learn about large structural shocks or gradual changes in the trend of a variable. Furthermore, while a sizable fraction of forecasters seem to smooth their GDP forecasts significantly, this does not apply to forecasts made for other macroeconomic variables.     

区域物流发展水平与进出口贸易关系的实证研究——基于河南省1978-2010年数据的协整分析和Granger因果检验

从供给和需求两个视角选取物流业发展水平的评价指标,对河南省物流业发展水平与进出口贸易增长关系进行了计量分析。通过Johansen协整检验得出:河南省物流业的供给和需求水平与进出口贸易之间存在长期稳定的协整关系;通过Granger因果检验得出:河南省物流业需求水平对进出口贸易有显著的影响,而物流业供给水平对进出口贸易影响不显著,物流业总体发展水平与进出口贸易之间未呈现良性互动态势。     

Are Google searches making the Bitcoin market run amok? A tail event analysis

This paper aims at detecting extreme value spillover between the large co-movements of Bitcoin returns and the rate of change in investor attention (for which Google search is used as a proxy). For this purpose, we use the concept of the Granger causality in tail event. Thus, we test whether positive, or negative, extreme values of rate of change in Google searches have a significant predictive power for negative, or positive, large values of Bitcoin returns, and vice versa . Our results shed light on a unidirectional causality effect from the returns to investor attention in the first place, before becoming bidirectional when the time delay increases.     

鲜活农产品拍卖市场品类价格波动的相关性分析与检验

协整与Granger因果检验被广泛应用于宏观经济领域经济变量间的关系分析中,但是,将协整与Granger因果检验应用于企业微观市场结构经济变量之间的分析的文献还鲜见报道。论文选择昆明国际花卉拍卖市场2009年2月16日至2010年2月12日间玫瑰的交易数据,分析鲜活农产品拍卖市场品类价格波动的相关性及其影响。实证结果表明:价格与供货量存在长期的均衡关系,供货量是价格的内生变量;价格对滞后一期的供货量产生影响,供货量则影响滞后三期的价格;此外,价格对滞后三期的流拍率产生影响,但流拍率的变化不会对价格产生影响。
