We study stationary discretionary equilibria in dynamic linear-quadratic rational expectations models. Past papers have assumed that this is uniquely determined; we show that such models can have multiple equilibria in some situations. We demonstrate the existence of multiple discretionary...

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...
