Stock Market Interactions between the BRICS and the United States: Evidence from Asymmetric Granger Causality Tests in the Frequency Domain
The interaction of BRICS stock markets with the United States is studied using an asymmetric Granger causality test based on the frequency domain. This type of analysis allows for both positive and negative shocks over different horizons. There is a clear bivariate causality that runs both ways between the United States stock market and the respective BRICS markets. In addition, both negative a...
متن کاملThe Relationship Between Consumer Confidence Index and Online Credit Card Using in Turkey: New Evidence From Frequency Domain Causality Test
Monthly data for the period between January 2008 and December 2012 were examined in this study which investigated the relationship between consumer confidence index (CCI) and online credit card using (CCU). The variables were found to have an integrated structure after testing of the collected data with Hatemi-J cointegration test (2008) which enables two-structural break. It has been observed ...
متن کاملGlobal temperatures and sunspot numbers. Are they related? Yes, but non linearly. A reply to Gil-Alana etal.(2014)
Recently Gil-Alana et al. (2014) compared the sunspot number record and the temperature record and found that they differ: the sunspot number record is characterized by a dominant 11-year cycle while the temperature record appears to be characterized by a ‘‘singularity’’ or ‘‘pole’’ in the spectral density function at the ‘‘zero’’ frequency. Consequently, they claimed that the two records are c...
متن کاملSaving, Investment, and Growth: A Causality Test
In the second half of the last century, tremendous efforts were devoted to identifying sources of economic success by a few countries and causes of failure by most. In this process a voluminous literature ranging from the neo-classical to Marxist, neo-Marxist, and dependency theories has been developed to answer the question of disparity among different countries of the north vis-à-vis those of...
متن کاملObjective Calibration of Sunspot Numbers
Waldmeier [1971] found a very tight relationship between the F10.7 solar radio flux and the sunspot number and suggested using the flux for an objective calibration of the sunspot number. He suggested that if this relationship changed later on, the sunspot number should be recalibrated, assuming that the calibration must have drifted with time. I repeat his analysis using data up to the present...
