 am interested in evaluating the marginal effect of seeing an advertising impression on conversion (binary). 
However, because of activity bias , the number of impression seen is correlated with the unobserved error and are therefore exogenous. 

I was thinking about using an IV to get around this problem. The instruments that I have are number of impressions of similar users on that day. 
That seems very much like a matching estimator. 

Is this possible? Is there a way of doing this in Stata?
