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...

We present an estimated dynamic stochastic general equilibrium model of stock market bubbles and business cycles using Bayesian methods. Bubbles emerge through a positive feedback loop mechanism supported by self-fulfilling beliefs. We identify a sentiment shock that drives the movements of...

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...

Prior research shows that disagreement leads to speculative trading and a speculative premium in stock prices. We examine how managers respond to this speculative premium. Using exogenous variation in speculative trading due to the reconstitution of the Russell 1000/2000 indices, we find that...
