Least Square Dummy Variable Regression V.S. Fixed Effect Model

WebA fixed effect model is an OLS model including a set of dummy variables for each group in your dataset. In our case, we need to include 3 dummy variable - one for each country. The model automatically excludes one to avoid multicollinearity problems. Results for our policy variable in the fixed effect model are identical to the de-meaned OLS. WebMultiple Fixed Effects Can include fixed effects on more than one dimension – E.g. Include a fixed effect for a person and a fixed effect for time Income it = b 0 + b 1 Education + Person i + Year t +e it – E.g.
