Introduction to the macroeconomic dynamics: special issues on money, credit, and liquidity
We motivate and provide an overview to New Monetarist Economics. We then briefly describe the individual contributions to the Macroeconomics Dynamics special issues on money, credit and liquidity.

Diamond-Dybvig and Beyond: On the Instability of Banking
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 consider several formalizations: insurance-based banking, models with reputational considerations, those with fixed costs and delegated investment, and those where bank liabilities serve as payment instruments. Importantly for the issue at hand, in each case banking arrangements arise endogenously. ...

General equilibrium with nonconvexities, sunspots, and money
We study general equilibrium with nonconvexities. In these economies there exist sunspot equilibria without the usual assumptions needed in convex economies, and they have good welfare properties. Moreover, in these equilibria, agents act as if they have quasi-linear utility. Hence wealth effects vanish. We use this to construct a new model of monetary exchange. As in Lagos-Wright, trade occurs in both centralized and decentralized markets, but while that model requires quasilinearity, we have general preferences. Given our specification looks much like the textbook Arrow-Debreu model, we ...

The 2007 Summer Workshop on Money, Banking and Payments: an overview
The 2007 Summer Workshop on Money, Banking, Payments and Finance met at the Federal Reserve Bank of Cleveland this summer, as we have over the past several years. The following document summarizes and ties together the contributions presented at the workshop this year.

A discussion of Cooley and Hansen's \\"welfare costs of moderate inflations.\\"
This is a note on the analysis of inflation and taxation in Cooley and Hansen?s cash-in-advance economy described in their paper ?The Welfare Costs of Moderate Inflations.? Basic issues concerning the costs and consequences of inflation are considered, their results are assessed, and some directions for extensions are suggested.

More on money as a medium of exchange
We extend the analysis of Kiyotaki and Wright, who study an economy in which the different commodities that serve as media of exchange are determined endogenously. Kiyotaki and Wright consider only symmetric, steady-state, pure-strategy equilibria, and find that for some parameter values no such equilibria exist. We consider mixed-strategy equilibria and dynamic equilibria. We prove that a steady-state equilibrium exists for all parameter values and that the number of steady-state equilibria is generically finite. We also show, however, that there may be a continuum of dynamic equilibria. ...

Liquidity and asset market dynamics
We study economies with an essential role for liquid assets in transactions. The model can generate multiple stationary equilibria, across which asset prices, market participation, capitalization, output and welfare are positively related. It can also generate a variety of nonstationary equilibria, even when fundamentals are deterministic and time invariant, including periodic, chaotic, and stochastic (sunspot) equilibria with recurrent market crashes. Some equilibria have asset price trajectories that resemble bubbles growing and bursting. We also analyze endogenous private and public ...

The business cycle and the life cycle
The paper documents how cyclical fluctuations in market work vary over the life cycle and then assesses the predictions of a life-cycle version of the growth model for those observations. The analysis yields a simple but striking finding. The main discrepancy between the model and that data lies in the inability of the model to account for fluctuations in hours for individuals in the first half of their life cycle. The predictions for those in the latter half of the life cycle are quite close to the data.
