Over the past few years, our common assumptions about what defines successful macroeconomic policy has shifted. The COVID-19 forced massive government spending throughout the world especially in nations like Japan and the United States. In this paper, I hope to investigate an alternative understanding of the reaction to the COVID-19 pandemic, Modern Monetary Theory or MMT. MMT reforms our understanding of how currency and government work and creates an interpretation that justifies liberal government spending for the public good. MMT-based policy changes how governments react to excess financial pressure. Japan and the United States serve as the preeminent example of this problem today. Japan's reaction to the COVID-19 pandemic incorporated similar stimulus spending to the US, however, unlike the US in the aftermath of increased inflation after the pandemic Japan maintained high stimulus spending, maintained high employment, and kept low interest rates. While all of these policies are in accordance with an MMT-based approach, the government has been reluctant to give a public endorsement. I hope to study the ability of the approach countries like Japan have taken to help solve these important issues. I want to see if these approaches are applicable to the United States and other nations. To study this, I will read advanced literature on both MMT and mainstream economics. I will also consult with Bill Mitchell, one of the leading professors of MMT and study publicly available data to back up my findings. I will write a paper on my findings for how MMT based policy can become a valuable tool in developed nations.
