We design a new, implementable capital requirement for large financial institutions (LFIs) that are too big to fail. Our mechanism mimics the operation of margin accounts. To ensure that LFIs do not default on either their deposits or their derivative contracts, we require that they maintain a...

We study an economy where the lack of a simultaneous double coincidence of wants creates the need for a relatively safe asset (money). We show that, even in the absence of asymmetric information or an agency problem, the private provision of liquidity is inefficient. The reason is that liquidity...

This Paper evaluates the primary mechanisms for changing management or obtaining control in publicly traded corporations with dispersed ownership. Specifically, we analyse and compare three mechanisms: (1) proxy fights (voting only); (2) takeover bids (buying shares only); and (3) a combination...

What determines how integrated a firm is? We emphasize the benefits of "control" when there are difficulties in writing complete contracts. We define the firm as being composed of its assets. We present a theory of costly contracts which emphasizes that contractual rights can be of two types:...

When drawing up a contract, it is often impracticable to specify all the possible relevant contingencies, and so contracts are typically incomplete. This paper considers the extent to which these gaps might be filled by building into the contract a mechanism for revising the terms of trade. One...

What is so special about banks that their demise often triggers government intervention? In this paper we show that, even ignoring interconnectedness issues, the failure of a bank causes a larger welfare loss than the failure of other institutions. The reason is that agents in need of liquidity...

We study the role of fiscal policy in a complete markets model where the only friction is the non-pledgeability of human capital. We show that the competitive equilibrium is constrained inefficient, leading to too little risky investment. We also show that fiscal policy following a large...
