We study the interplay of optimal ex-ante (macroprudential) and ex-post (monetary or fiscal stimulus) measures to respond to systemic financial crises in a tractable model of fire sales. We find that it is generally optimal to use both, rejecting the Greenspan doctrine to only intervene ex post....

This paper analyzes prudential controls on capital flows to emerging markets from the perspective of a Pigouvian tax that addresses externalities associated with the deleveraging cycle. It presents a model in which restricting capital inflows during boom times reduces the potential outflows...

This paper considers the labor market and distributional implications of a scenario of ever-more-intelligent autonomous machines that substitute for human labor and drive down wages. We lay out three concerns arising from such a scenario and evaluate recent predictions and objections to these...

Imperfections in risk and capital markets imply that individuals who lose jobs suffer from imperfect smoothing of consumption across states and times. Compared to the first best, there will be too little search. Optimal unemployment programs, which balance the marginal benefit of consumption...
