Jennie,
Your study seems to be in the political science area and I'd bet this is not the first time somebody has had a dataset like yours and has analyzed for policy shock effects. Step 1: find and read those articles.
Now, to give us something to work with state a specific hypothesis/variable that will show the effect and indicate whether you expect the effect to be a transient or a 'permanent' change in level.

Subject: Matched Pairs, Treatment-Control, Interrupted Panel Study -- What Model will Work?
Hi Out There!
I have a beautiful balanced panel dataset from 1998 to 2011, of election results (incumbents re-elected, party turnover, voter turnout, etc.) for municipalities in the USA, with no missing values. I have matched 25 treatment cities to 25 control cities. All of the treatment cities experienced a certain policy shock at different times between 2007 and 2011; the control cities are similar in demographic composition and region, but did not experience the shock. I also have relevant control variables from the Census data.
In summary, I have a setup for a matched-pairs, treatment-control, interrupted panel study. I want to use a panel method to estimate the effect of that shock. I am writing to this list because I am not sure what statistical method is suitable for this type of study.
Does anyone have any suggestions?
Thanks!!
Jennie
