Banks are vulnerable to self-fulfilling panics because their liabilities (such as demand deposits and certificates of deposit) are short term and unconditional, and their assets (such as mortgages and business loans) are long term and illiquid. To prevent wider financial fallout from such...

Banks are prone to panic-induced runs due to their traditional structure of short-term, unconditional liabilities and long-term, illiquid assets. To avoid systemic crises caused by such panics, governments tend to bail out failing banks. Traditional banking systems thus impose external costs....

In this paper we argue that if monetary policy has insufficient deflation, private agents have incentives to set up alternative payment systems like fractionally backed bank deposits, which pay interest on the means of payment. In a competitive environment with free entry, these alternative...

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...

We develop a model in which, in order to provide managerial incentives, it is optimal to have costly bankruptcy. If benevolent governments can commit to their policies, it is optimal not to interfere with private contracts. Such policies are time inconsistent in the sense that, without...

Innovative activities have public good characteristics in the sense that the cost of producing the innovation is high compared to the cost of producing subsequent units. Moreover, knowledge of how to produce subsequent units is widely known once the innovation has occurred and is, therefore,...

The desirability of fiscal constraints in monetary unions depends critically on whether the monetary authority can commit to follow its policies. If it can commit, then debt constraints can only impose costs. If it cannot commit, then fiscal policy has a free-rider problem, and debt constraints...

The central puzzle in international business cycles is that fluctuations in real exchange rates are volatile and persistent. We quantity the popular story for real exchange rate fluctuations: they are generated by monetary shocks interacting with sticky goods prices. If prices are held fixed for...

We propose a definition of involuntary unemployment which differs from that traditionally used in implicit labor contract theory. We say that a worker is involuntarily unemployed if the marginal wage implied by the optimal contract exceeds the marginal rate of substitution between leisure and...

We propose a definition of time consistent policy for infinite horizon economies with competitive private agents. Allocations and policies are defined as functions of the history of past policies. A sustainable equilibrium is a sequence of history-contingent policies and allocations that satisfy...
