Just yesterday I was challenged on this question. For all my life, I've been thinking, almost intuitively in fact, that it was obvious that economics was just a reflection of politics. Then I was challenged by someone that said "What your writing is economics. It's not political science."
My usual retort to such a statement is well, "What is the term political economy all about then?"
I think, for the lay person, that retort is enough. Politics is economics. Economics is politics. And then we can move on to the next topic over beers.
But to an academic, this debate is fodder for a career. If economics and political science turn out to be two sides of the same coin, why not just put them both in one department? In the belt-tightening era to almost certainly come to academia as a result of the COVID-19 Crisis, think of all the money endowments could save!
Kidding aside, I think this question is an interesting one and a worthy pursuit. Maybe I could be convinced that they are indeed separate pursuits. If you have any opinion, please include a detailed explanation below and I will reward with a full upvote!
Depending on the response, I might even make a community about this topic. Assuredly, there is more to talk about here. But for now, I think I will just leave it to be crowdsourced.
