relationship between economy and economic policy.

It’s the paper demanded from the course of social science and I prepare the materials attached below.
The topic I choose is about the relationship between economy and economic policy. The dependent variable is the economy and there are three independent variables. They are monetary policy, fiscal policy and supply side policy. You should explain how these three influences the economy in some ways from the articles I listed.
The paper needs six resources: one point from a data site and five articles which is specific. Also, I attached these five articles below, but you need to add one more sources from a data site. It could be about global economy and economic policy, or other relative data.
Just check it from the document and remember to ask me if you have any questions.
