We discussed four major historical examples of US fiscal policy that were passed by Congress and begun under four presidents in the following years: Reagan (1981), George W Bush (2001-3), Obama (2009) and Trump (2018). In broad terms, describe each of the four examples, being sure to highlight any general differences between the examples and their effects on the economy.

Can we know precisely how well these or other fiscal policy actions worked? Why or why not?

Please make sure that the response is only 3 paragraphs long. One paragpah should be about 4-5 senetnces only. It shouldnt be long. Thank you.
