SpaceTime 4.0 is cross-platform mathematics software available for the iPhone/iPad under iOS, as well as other devices. It can be used to implement usable DSGE modeling tools; this includes the solution of linear rational expectations, solving optimal linear-quadratic policy problems, obtaining...

We consider a nonparametric testing procedure for long-run monetary neutrality using spectral approaches. Long-run effects between bivariate integrated series are represented as the spectral density matrix of their first-differences evaluated at the zero frequency. The long-run neutrality, the...

This article devotes to studying the variance change-points problem in student t linear regression models. By exploiting the equivalence of the student t distribution and an appropriate scale mixture of normal distributions, a Bayesian approach combined with Gibbs sampling is developed to detect...
