It then sketches a two-period model combining informed-but-constrained and uninformed-but-unconstrained agents, and previews the capital-multiplier mechanism. A separate literature review follows. The model and its equilibrium are set out formally, and the main results cover fire sales, market freezes, and welfare. An extension endogenizes margin constraints as a robustness check. A discussion section covers fragility, policy, and the 2007-08 crisis, and the conclusion restates the mechanism.
