Need help with interpretation

[Georgie]

Hey guys, I have trouble interpreting the results of a LS-estimation. All my independent variables are stationary. URATE (dependent variable) consists of the first differences from the raw data. Do I have to make the dependent variable stationary as well? (which it is now because of the first differences)
OIL and REAL are the first differences from the raw data as well.
UNEMPLOY, EMPLOY, EXPO are the first differences of the ln values from the raw data. CRISIS and SANC are date-dummies.

I am struggling with the interpretation. How do I interpret all the independent variables in relation to the dependent variable URATE except the 2 date-dummies?
