In your SOP, you should address the following:
Why do you want to do research in Economics/Policy? What is your research interest? (Here write about your motivation to do research in Economics/Policy and what is your area/question of interest?)
Can you explain how your studies and experience make you suitable to do research in Economics/Policy? How will they help with the graduate coursework?Â
Past research experience/Dissertation details.
Ambitions/Future Goals and how Research in Economics will help.
Any other relevant Information or weakness in your profile which you would like to discuss. Only discuss weakness if you cannot hide it.
The SOP is not THAT important-- a good SOP will not tip the scale in your favor, but a bad SOP will ruin any chance you had.
