Endogenous business cycles via state-dependent saving and noise-induced metastability
Shenglan Yuan, James Brannan, Almaz Abebe +1
We develop a parsimonious stochastic growth model in which state-dependent saving behavior generates endogenous business-cycle-like dynamics. The model consists of three coupled eq…

Stochastic bifurcation in economic growth model driven by Lévy noise
Almaz Abebe, Shenglan Yuanb, Daniel Tesfay +1
This paper enhances the classical Solow model of economic growth by integrating Lévy noise, a type of non-Gaussian stochastic perturbation, to capture the inherent uncertainties i…

Dynamic Systems Framework for Modeling COVID-19 with Lévy Noise
Daniel Tesfay, Almaz Tesfay, James Brannan
Natural fluctuations have played a crucial role in affecting the dynamics of pervasive diseases such as the coronavirus. Examining the effects of irregular unsettling disturbances…
