Dear Emiel
This is interesting. But the logic is very clear , If there is no relationship between two variables , why we should try to establish one.
I am not sure but cannot a factor analysis give some guidance as to reduce the concerned variables
I also think some omitted variable may do the trick
I feel these suggestions may not exacrly address the problem in hand then soory to give suggestions.

Hello,
For my school these, i am doing research to investigate the effect of different variables on the reserve currency shares of different currencies. Before i am working with panel data, i liked to make an OLS estimation on the dollar. So i'm using time series data. I checked the variables for stationarity using the ADF-test, and it seems that the dependent variable is non-stationary along with two explanatory variables. The other 4 explanatory variables are stationary. Since you cannot run regressions with variables of a different integration, i am not sure how to proceed.. I suggest it is not appropriate to just take the first differences of the non-stationary variables?
Any help on this topic would be very much appreciated. Thanks in advance.
For additional info on the data/research, please do not hesitate to contact me.
