Estimating DSGE models across time and frequency

Using a wavelet-based decomposition, this paper exploits the information in the data usually employed in the estimation of DSGE models. A simple New Keynesian model featuring price and wage rigidities is estimated for the United States across different frequencies. The estimations indicate that most structural parameters exhibit a frequency-dependent behavior. The impulse response functions also indicate frequency-dependent responses of output to the exogenous shocks. For lower frequencies, there are more persistent effects, especially for preference and technology shocks.
