IPE DATA RESOURCE
The IPE Data Resource combines 70 commonly used country-year datasets into a single entity, with a focus on component datasets relevant to the field of IPE. I hope this may be of use both to researchers gathering variables for robustness checks and to methods instructors who want students getting their hands dirty with real data, but want to limit the time devoted to data management.
