California State University Northridge Economics Question

Your data indicates that the stock market indices of all the countries studied increased between 2005 and 2006. Unexpectedly, interest rates for all but one country also increased during that period. Perhaps this is partially due to the positive inflation rates in all of these countries. You would like to find out more information. However, there are variations in the direction and in the size of these changes for each country and this complicates your analysis.
