Hi all
I'm recently doing a empirical study need to match case sample with one or more potential benchmark samples using a specific measure and see if there is an statistically significant effect of the given treatment to the case firms, all the data are observational ones.
after I matched the cases with controls using , say inventory, I want to test whether the match is or not, So I use paired t test on inventory of the matched pairs, but the testing result show that they are significantly different, I went to draw a plot of paired inventory and they seems like almost perfectly matched.
I checked out several times and still don't know why ,really need your help . below is my code and data
see the attachment for data the variable I matched on is IR, and all variables with "U" are from the matched firms(control) others are are belong to cases. the difference between IR and IR_U should be very small, at least no statistically significant since each IR_U is within (0.9- 1.1)*IR, this is how the matching process performed any way.
this is only part of the data for the size sake, and we could not attach a dat file here?
thanks in advance for any suggestions.
