We analyze a new class of equilibria that emerges when a central bank conducts monetary policy by setting an interest rate (as an arbitrary function of its available information) and letting the private sector set the quantity traded. These equilibria involve a run on the central bank's interest...

The purpose of this paper is to convince the reader that the Continental dollar was a zero-interest bearer bond and not a fiat currency--thereby overturning 230 years of scholarly interpretation; to show that the public and leading Americans knew and acted on this fact, and to illustrate the...

This paper is an exercise in comparative institutional analysis, asking what kinds of arrangements most facilitate innovation. After identifying pervasive market failures in innovation, it explains why those associated with the Nordic model may be particularly conducive to innovation, and...

This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

We study the optimal provision of insurance against unobservable idiosyncratic shocks in a setting in which a benevolent government cannot commit. A continuum of agents and the government play an infinitely repeated game. Actions of the government are constrained only by the threat of reverting...

We develop a dynamic model of trading and investment with limited aggregate resources to study investment cycles. Unverifiable idiosyncratic investment opportunities imply market prices to play a role of rent distribution, distorting private investment incentives from a social point of view....

We study information acquisition and dynamic withdrawal decisions when a spreading rumor exposes a solvent bank to a run. Uncertainty about the bank's liquidity and potential failure motivates depositors who hear the rumor to acquire additional noisy signals. Depositors with less informative...

This paper studies debt fragility and the sharing of the resulting strategic uncertainty through ex post bailouts. Default arises in equilibrium because of both fundamental shocks and beliefs. The probability of default depends on borrowing rates and, in equilibrium, on the beliefs of lenders...

I analyze monetary policy with interest on reserves and a large balance sheet. I show that conventional theories do not determine inflation in this regime, so I base the analysis on the fiscal theory of the price level. I find that monetary policy can peg the nominal rate, and determine expected...

We study the optimal Mirrlees taxation problem in a dynamic economy with idiosyncratic (productivity or preference) shocks. In contrast to the standard approach, which implicitly assumes that the mechanism is operated by a benevolent planner with full commitment power, we assume that any...
