We analyze exchange-rate management by the central bank when it makes the FX market for the sake of social-welfare objectives. It is assumed that markets are incomplete, so that agents are exposed to exchange-rate volatility against which they cannot fully hedge. It follows that the central bank...

The basic question regarding sovereign debt is why sovereign borrowers ever repay, provided that creditors have no power to foreclose on any of their assets. In this paper we suggest an answer: sovereign debt will be served as long as the median voter is a net loser from default. Default...

Leveraged investors may be subject to contagion when sales of repossessed collateral create a downward spiral in fire sales prices, increasing margin requirements and drying up the supply of liquidity. This raises the question whether market integration is desirable when the risk of contagion is...

We develop a theoretical model where a redistribution of bank capital (e.g., due to reckless trading and/or faulty risk management) leads to a “freeze” of the interbank market. The fire-sale market plays a central role in spreading the crisis to the real economy. In crisis, credit rationing...

Motivated by the observation that exchange-rate management resembles market-making, we use microstructure theory to conduct a welfare analysis of exchange-rate management, includ-ing the "corner solutions" of a free float and a fixed peg. We show that a policy that smoothes out exchange-rate...

We develop a theory of sovereign borrowing where default penalties are not implementable. We show that when debt is held by both domestic and foreign agents, the median voter might have an interest in serving it. Our theory has important practical implications regarding (a) the role of financial...
