We analyze agents' decisions to act as producers or intermediaries using equilibrium search theory. Extending previous analyses in various ways, we ask when intermediation emerges and study its efficiency. In one version of the framework, meant to resemble retail, middlemen hold goods, which...

Are financial intermediaries-in particular, banks-inherently unstable or fragile, and if so, why? We address this question theoretically by analyzing whether model economies with financial intermediation are more prone than those without it to multiple, cyclic, or stochastic equilibria. We...

This paper revisits the no-recall assumption in job search models with take-it-or-leave-it offers. Workers who can recall previously encountered potential employers in order to engage them in Bertrand bidding have a distinct advantage over workers without such attachments. Firms account for this...

We study the use of asset-backed money in a neoclassical growth model with illiquid capital. A mechanism is delegated control of productive capi- tal and issues claims against the revenue it earns. These claims constitute a form of asset-backed money. The mechanism determines (i) the number of...

In the United Kingdom, money demand deviates from the convex relationship suggested by monetary theory. Limited commitment of borrowers via banks can explain this observation. Our finding is based on a microfounded monetary model, where a money market provides insurance against idiosyncratic...

In response to the financial crisis of 2007/08, all major central banks decreased interest rates to historically low levels and created large excess reserves. Central bankers and academics currently discuss how to implement monetary policy, going forward. We find that paying interest on reserves...

The fact that money, banking, and financial markets interact in important ways seems self-evident. The theoretical nature of this interaction, however, has not been fully explored. To this end, we integrate the Diamond (1997) model of banking and financial markets with the Lagos and Wright...

Major central banks remunerate reserves at negative interest rates and it is increasingly likely that they will keep rates negative for many more years. To study the long run implications of negative rates, we construct a dynamic general equilibrium model with commercial banks funding investment...

In the 1990s, the empirical relation between money demand and interest rates began to fall apart. We analyze to what extent improved access to money markets can explain this break-down. For this purpose, we construct a microfounded monetary model with a money market, which provides insurance...

We extend the analysis of the interbank market model of Gale and Yorulmazer (2013) by studying a larger set of trading mechanisms. A trading mechanism, which allows for randomized trading, restores efficiency. In contrast to Gale and Yorulmazer, we find that fire-sale asset prices are efficient...
