I have a problem that has been plaguing me for the last couple of days but I still can't work it out - I'm sure this is pretty straightforward but my maths seems to be a little rusty. I would appreciate anyone that can help me out here as this is for my dissertation.
If their are two equations:
log(a)=tlog(b)+ulog(c)+vlog(d) + w
where a, b, c, d, e, f are variables and t, u, v, w, y, z are constants
Note that f is not in logarithmic form, how can I calculate what percentage change a 1% increase in f would cause a?

Substitute the second equation into the first, then rearrange for a alone on the LHS, then calculate , where a(f) is the expression you calculated for a in terms of all the other variables including f. (I'm using a(f) as a function, not multiplication.) Then you can divide one by the other to get the ratio change.
