Hi,
I am trying to put together a research proposal for a PhD in Economics. It will lean towards political economy/history. I want to look at the economics of a cashless society, namely the ability of central banks to use negative interest rates as a tool against recessions. But I am stuck on the methodology section... because I think I will be looking for comparable examples in history to give insight into how a change now to a cashless society would work...
Any thoughts welcome, thank you in advance.
