I am running a regression model to identify the relationship between exposure to hate speech and the adoption of hate speech on a prominent forum, controlling for a host of other variables. Theoretically, I feel it makes sense for my measure of hate speech exposure to be lagged by t-1 time periods, to capture how exposure the previous month influences behaviour the following month.
The panel dataset I am using is an unbalanced one and contains around 12,000 forum members, whose posting behaviour is analysed over a period of 63 months.
Is there anything I should be weary of when implementing a fixed effects regression model in these circumstances?
