Slow growth in productivity

Explanation:

During the 1970s and early 1980s, the American economy suffered from high inflation and a decrease in productivity, mainly caused by a reduction of oil supply especially from Arab nations and an increase in its price.

Many industries that used oil as a major resource (e. g. automobile manufacturers, distribution companies, etc.) suffered greatly and their productivity lowered.

Since oil is a major resource, the negative effects of a supply reduction grew like a snowball and eventually affected the whole economy.
