I am a beginner at econometrics and I have to build a model explaining scholing (as dependent variable) by migration (independent variable) and a couple of covariables. I'm going to use fixed effects to do this.
Now my question is, where and why should I use a LOG? I already read a lot of questions and answers here but it didn't help me any further.
Should I log migration? Government expenditure on scholing? GDP/Capita? Literacy? Ratio of scholing?
