Abstract

We present a model of financial market liquidity provided by financially constrained intermediaries. We show that market liquidity increases with the level of intermediary capital. We also characterize conditions under which intermediaries play a stabilizing or destabilizing role in markets. Finally, we sketch a number of areas, including welfare and public policy, on which the model can shed light.
