Testing the hysteresis effect in the US state-level unemployment series

Omay, Tolga; Ozcan, Burcu; Shahbaz, Muhammed - In: Journal of applied economics 23 (2020) 1, pp. 329-348

This paper re-examines the stochastic time series behaviour of the monthly unemployment rate in 50 states of the United States (US) for the period 1976-2017 using a number of state-of-the-art unit root tests. The new developments incorporate structural break, nonlinearity, asymmetry, and...
