Dag iedereen.
For my masters thesis in corporate finance I'm doing a research about debt concentration (i.e. companies using several debt types or only 1, measured by HHI index) I've got several determinants and some control variables. My data consists of 24503 observations, from 2009-2013. For some companies I have the data for all 5 years, other companies are only once or twice in the dataset. I would like to do a regression with fixed effects. (year FE and firm FE) Question 1: Is this the correct choice, and why? I've also considered GEE but im not sure.
Sorry voor de Engelse, als het niet te verstaan is laat maar weten en dan doe ik de post in het Nederlands.
