α: calibrated so average coauthorship-adjusted count equals average raw count
There are two well-known conditions for the determinacy of equilibrium in MSRE (Markov-switching rational expectations) models. One is the long-run Taylor principle of Davig and Leeper (2007) and the other is by Farmer et al (2009). It is known that the former is merely a necessary condition. This note identifies a restriction on the solution under which the condition is sufficient as well as necessary.
