Panel data analysis

[winger]

Hello,

I'm doing research into explaining house prices before and after crisis, and do house prices react differently to the crisis regionally. I have a dataset with house prices of 33 cities ( dependend variable) and 7 ( yearly) explanatory variables over a time period of 17 years (1996-2011). I created a balanced panel (33-528), with an after crisis dummy variable ( 2008-2011) to see if house prices react differntly to variables after 2007.

Im really not sure if this is the right way to test my hypothesis. And if i have to use fixed cross-section or period effects or random cross-section or period effects?

Can you help me?

Thanks in advance,

Winger.
