Explanation of Solution

The dept to GDP ratio is the comparison of public debt of a country to its gross domestic product. This ratio indicates the ability to pay back debts of a particular country.

The following table represents the FRED data on gross federal debt held by the public as a percent of GDP for the United States:

  Macroeconomics, Chapter 1, Problem 5WWMD

The post-1945 period is considered to be the post-war era. Just after the Second World War in 1946 (the debt ratio was a high of 10,31331), the United States experienced sustained declines in the federal debt-to-GDP ratio. The decrease in the federal debt-to-GDP ratio lasts until 1974 (22.24246 debt-to-GDP ratio).

The most critical period of debt growth is the 1980 to 1995. The next biggest increase was from 1974 to 1979. The debt has exploded surprisingly since 2008 (the Great Recession), the period from 2008 to the end of 2013 continues to rise in the federal debt-to-GDP ratio of United States.

The causes of sharp debt-to-GDP ratio expansion are the rising income inequality of the country and its persistent deficit.

President N's decision to dissociate the dollar from the gold standard in 1971 was the first reason behind persistent deficit because dollars were no longer exchanged for gold and the government was free to spend as long as it could, worsening the deficits.

High income disparities and large deficits result in spending inequalities, so rise in the amount of U.S. debt persists as a weapon that can keep the economy from slowing down and increase unemployment.
