The Relationship Between Economic Growth and Unemployment in the US

The relationship between economic growth and unemployment has long been a central topic in macroeconomics. In 1962, Arthur Okun proposed Okun's Law, which states that increases in real GDP are generally associated with decreases in unemployment. Although this relationship has been widely studied at the national level, relatively few studies have examined whether it holds consistently across individual U.S. states during periods of both economic stability and economic crisis. The COVID-19 pandemic created an unprecedented disruption to labor markets, raising questions about whether this traditional macroeconomic relationship continued to apply.

This study examines the validity of Okun's Law across all fifty U.S. states during three distinct periods: the stable pre-pandemic year of 2019, the economic contraction of 2020, and the recovery period of 2021. The state-level unemployment rates and real GDP growth rates were obtained from publicly available government databases, and Ordinary Least Squares (OLS) regression, t-tests, and p-value analysis were used to estimate the Okun coefficient and determine statistical significance. The results indicate that Okun's Law largely held during 2019, with most states producing statistically significant negative coefficients, while the relationship weakened substantially during 2020 and 2021 as many states produced positive coefficients or statistically insignificant results, suggesting that the COVID-19 pandemic temporarily disrupted the historical relationship between economic output and unemployment.
