A well known result is that 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. We exploit these observations to devise diagnostic methods that are useful for...

Stock market prices are procyclical, while investment good prices are countercyclical. A real business cycle model calibrated to these observations implies that 75% of the cyclical variation in aggregate output is due to an investment-specific technology shock, while the rest is due to an...

Across different layers of the U.S. government there are surprisingly large differences in institutional provisions that impose fiscal discipline, such as constitutionally mandated deficit or debt limits, or specific tax bases. In this paper we develop a framework that can be used to...
