Resumo: This paper addresses long-term persistence in U.S. unemployment. Seasonal fractional integration models were applied to evaluate the conjugated effect of seasonal and non-seasonal long memory processes on the dynamics of unemployment rate series. Three levels of data aggregation were analyzed: US states, regional census divisions, and the national unemployment rate. Persistence was analyzed based on original data and after irregular components such as breaks and regimes had been removed using wavelet multi-resolution analysis. Our results have shown that, in both cases, the joint effects of seasonal and non-seasonal long memory processes result in strong persistence in unemployment series, providing strong evidence against the NAIRU hypothesis.
