We estimate a DSGE model with (S,s) inventory policies. We find that (i) taking inventories into account can significantly improve the empirical fit of DSGE models in matching the standard business-cycle moments (in addition to explaining inventory fluctuations); (ii) (S,s) inventory policies...

Conventional wisdom has it that inventory investment destabilizes the economy be-cause it is procyclical to sales. Khan and Thomas (2007) show that the conventional wisdom is wrong in a general equilibrium (S,s) model with capital. We argue that their finding is not robust - the conventional...

In this note, we revisit the univariate unobserved-component (UC) model of U.S. GDP by relaxing the traditional random-walk assumption of the permanent component. Since our general UC model is unidentified, we investigate the upper bound of the contribution of the transitory component, and find...

We offer a tractable dynamic theory where excessive credit creation by the frictional banking sector may lead to over-investment and then endogenous boom-bust cycles. We formalize the idea in a general equilibrium framework with banks and financially constrained heterogeneous firms. In the...

This study documents a hump-shaped empirical relationship between financial development and the aggregate savings rate across 12 Asian and 31 OECD economies. An incomplete-market model featuring both heterogeneous households and heterogeneous firms is provided to explain this hump-shaped...

Evidences from structural VAR show that new business formation positively co-moves with output under news shocks. The Jaimovich-Rebelo model augmented with firm dynamics can explain the empirical findings. The key assumption is endogenous survival rates for new entrants
