Can anyone suss out the interpretation of beta here:
D.log(gdp) = alpha + beta(log(military expenditure %)
Where D.log(gdp) = growth of GDP (first difference of log(GDP)
Would it be:
A 1% point increase in military expenditure is associated with a beta% point change in the growth of GDP?
OR
A 1% increase in military expenditure is associated with a beta % change in the growth of GDP?
OR neither?
N.B. Also what implication does the underlying variable military expenditure have being a %, wouldn't that make the interpretation a percentage point?
Thanks Labib
