In this paper the authors argue that a plausible reason why output and other major U.S. macroeconomic time series seem to follow a Markov switching process might be strictly related to expectations. The authors show that a time series of expectations of future output from the Survey of...

We develop a new class of nonlinear time-series models to identify nonlinearities in the data and to evaluate nonlinear DSGE models. U.S. output growth and the federal funds rate display nonlinear conditional mean dynamics, while inflation and nominal wage growth feature conditional...
