Isolating single campaign effects over a sales series I'm trying to wrap my head around the concept of advertising effectiveness and hit a wall when I tried to measure the quantitative effect of an advertising campaign on the sales tendency of a business.
As far as I know, this is an econometrics question, since I have isolate the effect of said campaign from past and future campaigns, but also from distribution, macro effects, competitor activity and random effects. 
Can you point me to a paper or a textbook that deals with this kind of problem?
You might take a look at the Causal Impact R package and accompanying paper.
