In Money, Payments, and Liquidity, Guillaume Rocheteau and Ed Nosal provide a comprehensive investigation into the economics of money, liquidity, and payments by explicitly modeling the mechanics of trade and its various frictions (including search, private information, and limited commitment). Adopting the last generation of the New Monetarist framework developed by Ricardo Lagos and Randall Wright, among others, Nosal and Rocheteau provide a dynamic general equilibrium framework to examine the frictions in the economy that make money and liquid assets play a useful role in trade. The second edition has been revised to reflect recent progress in the New Monetarist approach to payments and liquidity. Other chapters have been revised and updated, with new material on credit economies under limited commitment, open-market operations and liquidity traps, and the limited pledge ability of assets under informational frictions.
