Sharing the risk of settlement failure
Two policies toward payments-system risk are common, but superficially appear to be contradictory. One policy is to restrict the exposure to risk generated by one participant to other participants who are, by one measure or another, directly concerned with the risky participant. The other policy is to provide a ?safety net,? typically provided by government and funded by taxes collected from all participants and even from non-participants, to share losses due to ?systemic risk.? In this paper, we provide a model in which both of these policies can be constituents of an economically efficient ...

Thoughts on the Fed's role in the payment system
This essay concerns how the Federal Reserve?s role as a payment services provider can best be aligned with its broad mission to foster the integrity, efficiency, and accessibility of the U.S. payments system. A recommended strategy involves specialization in providing services where the central bank has a comparative advantage?notably, services directly related to providing a comprehensive, secure system of accounts for interbank settlement and potentially some additional services justified by economies of scope. If markets for other payment services evolve as expected, the recommended ...

Will the new $100 bill decrease counterfeiting?
A current U.S. policy is to introduce a new style of currency that is harder to counterfeit, but not immediately to withdraw from circulation all of the old-style currency. This policy is analyzed in a random-matching model of money, and its potential to decrease counterfeiting in the long run is shown. For various parameters of the model, three types of equilibria are found to occur. In only one does counterfeiting continue at its initial high level. In the other two, both genuine and counterfeit old-style money go out of circulation - immediately in one and gradually in the other. There are ...

Electronic bill presentment and payment--is it just a click away?
This article addresses the following questions about electronic presentment and payment (EBPP) in the business-to-consumer marketplace: Why aren't electronically presented bills always paid electronically? And, if EBPP does aid in the migration to fully electronic end-to-end payment, what are the barriers to its adoption.

Can a \\"credit crunch\\" be efficient?
Two observations have sometimes been viewed as evidence that the equilibrium allocations of intermediated credit markets are inefficient. First, low-income households' marginal propensity to consume is close to unity. Second, even high-income households seem to face nonprice constraints during recessions. This paper presents a model that possesses both of these features. (A recession is modeled as an economy in which the equilibrium level of investment is at its lowest possible level.) However, contrary to the conventional view, the equilibrium of this model is ex ante efficient. The model ...

Implementing efficient allocations in a model of financial intermediation
In a finite-trader version of the Diamond-Dybvig (1983) model, the symmetric, ex-ante efficient allocation is implementable by a direct mechanism (i.e., each trader announces the type of his own ex-post preference) in which truthful revelation is the strictly dominant strategy for each trader. When the model is modified by formalizing the sequential-service constraint (cf. Wallace, 1988), the truth-telling equilibrium implements the symmetric, ex-ante efficient allocation with respect to iterated elimination of strictly dominated strategies.

On the emergence of parliamentary government: the role of private information
The way many dictators have been deposed in the 20th century resembles the way a parliamentary form of government emerged in 13th-century England. This medieval example is worth examining because the features that led to its political reform are particularly clear. Despite what many think, that reform cannot be understood simply as a shift in military power from ruler to subjects. Rather, understanding the reform requires understanding that the English king had recently acquired private information crucial to his subjects. Such private information became important after England lost Normandy ...

Money as a mechanism in a Bewley economy
We study what features an economic environment might possess, such that it would be Pareto efficient for the exchange of goods in that environment to be conducted on spot markets where those goods trade for money. We prove a conjecture that is essentially due to Bewley [1980,1983]. Monetary spot trading is nearly efficient when there is only a single perishable good (or a composite commodity) at each date and state of the world; random shocks are idiosyncratic, privately observed, and temporary; markets are competitive; and the agents are very patient. This result is a fairly close analogue, ...
