I need help with STATA for my thesis. My topic is The Effect of Institutional Quality and Tax Avoidance on the Relationship Between Headquarter Relocation and Firm Performance. So my IV is HQ relocation (measured using a dummy variable where 0 is no relocation and 1 is relocation), my DV is firm performance (measured using net income), and my moderators are tax avoidance (measured using the effective tax rate) and institutional quality (measured using an arithmetic mean of the WGIs per year). My control variables are firm size, firm age, and perhaps type of headquarters (regional headquarters vs. corporate headquarters) and firm industry (measured using the SIC codes).
Now my dataset has panel data. I want to analyze whether firms that have relocated have improved firm performance and compare it to the control firms (which haven't relocated). I have data on all variables 3 years pre-relocation and 3 years post-relocation for each firm. So I have 6 years of data per firm (year 1-3 and year 5-7, where year 4 is the year of relocation and will not be included in the analysis). My teacher told me to use ANOVA but I don't know if this is the best analysis to do since my dataset has relocated firms AND non-relocated firms of which I want to compare the pre- and post-relocation results to. I also need to include the moderators and the control variables. I have already tried some things but I can't figure it out and am therefore asking for help!
