I am conducting Fixed Effects Regression Analyses (Panel Regression) to analyze characteristics of firm-disclosures. My dependent variable is a disclosure characteristic (e.g. length, sentiment, ..). Obviously, I have one observation for each firm-year (firm-level). However, my independent variables also include manager data (e.g. age). I have data for multiple managers for each firm-year (manager-level), which I all want to include.
As priorly described, the green dependent variable (Length) is repeated for the manager-level perspective. However, manager-level data vary within firm-years. Fixed Effects are included for years and firms.
From a statistical perspective - can I run such regression analyses? If not, what is a proper procedure?
