What is so special about banks that their demise often triggers government intervention? In this paper we develop a simple model where, even ignoring interconnectedness issues, the failure of a bank causes a larger welfare loss than the failure of other institutions. The reason is that agents in...

This paper investigates whether the quantity theory of money is still alive. We demonstrate three insights. First, for countries with low inflation, the raw relationship between average inflation and the growth rate of money is tenuous at best. Second, the fit markedly improves, when correcting...

We study the role of fiscal policy in a complete markets model where the only friction is the nonpledgeability of human capital. We show that the competitive equilibrium is constrained inefficient, leading to too little risky investment. We also show that fiscal policy following a large negative...

Colonial Americans complained that gold and silver coins (specie) were chronically scarce. These coins could be acquired only through importation. Given unrestricted trade in specie, market arbitrage should have eliminated chronic scarcity. A model of efficient barter and local inside money is...

Despite advances in transactions technologies, paper currency still constitutes a notable percentage of the money supply in most countries. For example, it constitutes roughly 10% of the US Federal Reserve's main monetary aggregate, M2. Yet, it has important drawbacks. First, it can help...

We demonstrate that a rapid expansion in the supply of mortgages driven by disintermediation explains a large fraction of recent U.S. house price appreciation and subsequent mortgage defaults. We identify the effect of shifts in the supply of mortgage credit by exploiting within-county variation...

We present a model that characterizes the relationship between optimal dynamic cash management and the choice of the means of payment. The novel feature of the model is the sequential nature of the payments choice: in each instant the agent can choose to pay with either cash or credit. This...

An examination of U.S. banking history shows that economically efficient private bank money requires that information-revealing securities markets for bank liabilities be closed. That is, banks are optimally opaque, which is why they are regulated and examined. I show this by examining the...
