* $\theta_0^R < \theta^{MPE} $: the initial Ramsey inflation rate exceeds the MPE inflation rate

* $\theta_\infty^R < \theta^{CR} <\theta_0^R$: the initial Ramsey deflation rate, and the associated tax distortion cost $c \mu_0^2$ is less than the limiting Ramsey inflation rate $\theta_\infty^R$ and the associated tax distortion cost $\mu_\infty^2$
