“…Our paper is closely related to the recent work of Anzoategui, Comin, Gertler, and Martinez (2019), Benigno and Fornaro (2018), Bianchi, Kung, and Morales (2019), Garcia-Macia (2015), Guerron-Quintana and Jinnai (2019), Moran and Queraltó (2018) and Queralto (2019), all of whom integrate endogenous growth into a standard business cycle framework. Among these papers, our framework is most similar to that of Benigno and Fornaro (2018), who identify the possibility of an economy entering a phase characterized by a persistent liquidity trap and low TFP growth due to pessimistic expectations.…”
