The authors illustrate the use of various frequency-domain tools for estimating and testing dynamic, stochastic, general-equilibrium models. Their substantive results confirm other findings that suggest that time-to-plan in investment technology has a potentially useful role to play in...

The Gaussian log-likelihood can be expressed as the sum over different frequency components. This implies that the likelihood ratio statistic has a similar linear decomposition. Exploiting these observations, the authors devise diagnostic methods that are useful for interpreting...
