On the irrelevance of the maturity structure of government debt without commitment
This paper presents a government debt game with the property that if the timing of debt auctions within a period is sufficiently unfettered, the set of equilibrium outcome paths of real economic variables given the government has access to a rich debt structure is identical to the set of equilibrium outcome paths given the government can issue only one-period debt.

Should We Worry About Excess Reserves?
Banks in the United States have the potential to increase liquidity suddenly and significantly?from $12 trillion to $36 trillion in currency and easily accessed deposits?and could thereby cause sudden inflation. This is possible because the nation?s fractional banking system allows banks to convert excess reserves held at the Federal Reserve into bank loans at about a 10-to-1 ratio. Banks might engage in such conversion if they believe other banks are about to do so, in a manner similar to a bank run that generates a self-fulfilling prophecy. {{p}} Policymakers could guard against this ...

Sequential equilibria in a Ramsey tax model
This paper presents a full characterization of the equilibrium value set of a Ramsey tax model. More generally, it develops a dynamic programming method for a class of policy games between the government and a continuum of consumers. By selectively incorporating Euler conditions into a strategic dynamic programming framework, we wed two technologies that are usually considered competing alternatives, resulting in a dramatic simplification of the problem.

Too Correlated to Fail
In this paper, we argue that the anticipation of bailouts creates incentives for banks to herd in the sense of making similar investments. This herding behavior makes bailouts more likely and potential crises more severe. Analyses of bailouts and moral hazard problems that focus exclusively on bank size are therefore misguided in our view, and the policy conclusion that limits on bank size can effectively solve moral hazard problems is unwarranted.

Inequality and fairness
This study uses John Rawls' behind-the-veil of ignorance device as a fairness criterion to evaluate social policies and applies it to a contracting model in which the terms equality of opportunity and equality of result are well defined. The results suggest that fairness and inequality-even extreme inequality-are compatible. In a static world, when incentives must be provided, fairness implies equality of opportunity, but inequality of result. In a dynamic world of long-lived individuals, fairness implies not only inequality of result, but also, eventually, infinite inequality of result. If ...

Incentive compensation in the banking industry: insights from economic theory
How can banks and similar institutions design optimal compensation systems? Would such systems conflict with the goals of society? This paper considers a theoretical framework of how banks structure job contracts with their employees to explore three points: the structure of a socially optimal compensation system; the structure of a compensation system that is privately optimal, given the reality of government-guaranteed bank debt; and policy interventions that can lead from the second structure to the first. Analysis reveals a potential policy option: providing proper incentives to banks by ...

The Hammer and the Scalpel: On the Economics of Indiscriminate versus Targeted Isolation Policies during Pandemics
We develop a simple dynamic economic model of epidemic transmission designed to be consistent with widely used SIR biological models of the transmission of epidemics, while incorporating economic benefits and costs as well. Our main finding is that targeted testing and isolation policies deliver large welfare gains relative to optimal policies when these tools are not used. Specifically, we find that when testing and isolation are not used, optimal policy delivers a welfare gain equivalent to a 0.6% permanent increase in consumption relative to no intervention. The welfare gain arises because ...

Public trust and government betrayal
This paper presents a simple model of government reputation which captures two characteristics of policy outcomes in less developed countries: governments which betray public trust do so erratically, and, after a betrayal, public trust is regained only gradually.

On the Ethics of Redistribution
Analysts of optimal policy often advocate for redistributive policies within developed economies using a behind-the-veil-of-ignorance criterion. Such analyses almost invariably ignore the effects of these policies on the well-being of people in poor countries. We argue that this approach is fundamentally misguided because it violates the criterion itself.

A recursive formulation for repeated agency with history dependence
There is now an extensive literature regarding the efficient design of incentive mechanisms in dynamic environments. In this literature, there are no exogenous links across time periods because either privately observed shocks are assumed time independent or past private actions have no influence on the realizations of current variables. The absence of exogenous links across time periods ensures that preferences over continuation contracts are common knowledge, making the definition of incentive compatible contracts at a point in time a simple matter. In this paper, we present general ...
