| The annual structure of the U.S. unemployment rate is examined in this article by means of new statistical techniques developed by Robinson (1994), which permit us to test unit root cycles in raw time series. The tests have standard null and local limit distributions and unlike other procedures, they allow us to determine the number of periods per cycle. The results show that the cycles in the U.S. unemployment seem to occur approximately every four or five years. |
