So your dependent variable is "DEGD" which is a count variable with
basically a high number of zeros. Is that correct? If you find a
coefficient from the inflation part of the model to be negative then
means that per increase in x (the independent variable, however this
is scaled, let's assume it's continuous) the chance of having a zero
count decreases since you are predicting count=0 vs count>0.
