Linear RE models typically possess a multiplicity of solutions. Consider, however, the requirement that the solution coefficients must not be infinitely discontinuous in the model's structural parameters. In particular, we require that the solutions should be continuous in the limit as those...

Recent mainstream monetary policy analysis focuses on rational expectation solutions that are uniquely stable. A number of recent studies have examined the question of whether typical New Keynesian (NK) models, with policy rules that satisfy the Taylor principle, also exhibit solutions with...

Should central banks, because of the zero-lower-bound problem, raise their inflation-rate targets? Several arguments are relevant. (1) In the absence of the ZLB, the optimal steady-state inflation rate, according to standard New Keynesian reasoning, lies between the Friedman-rule value of...
