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. They discuss such topics as cashless economies; the properties of an asset that make it suitable to be used as a medium of exchange; the optimal monetary policy and the cost of inflation; the coexistence of money and credit; and the relationships among liquidity, asset prices, monetary policy; and the different measures of liquidity in over-the-counter markets.
The second edition has been revised to reflect recent progress in the New Monetarist approach to payments and liquidity. Rocheteau and Nosal have added three new chapters: on unemployment and payments, on asset price dynamics and bubbles, and on crashes and recoveries in over-the-counter markets. The chapter on the role of money has been entirely rewritten, adopting a mechanism design approach. 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 pledgeability of assets under informational frictions.
The recent downturn in economies worldwide have put monetary policies in a new spotlight. In addition to their investigations of new tools, models, and assumptions, they look carefully at recent evidence on subjects as varied as price-setting, inflation persistence, the private sector's formation of inflation expectations, and the monetary policy transmission mechanism. They also reexamine standard presumptions about the rationality of asset markets and other fundamentals. Stopping short of advocating conclusions about the ideal conduct of policy, the authors focus instead on analytical methods and the changing interactions among the ingredients and properties that inform monetary models. The influences between economic performance and monetary policy regimes can be both grand and muted, and this volume clarifies the present state of this continually evolving relationship.Presents extensive coverage of monetary policy theories with an eye toward questions raised by the recent financial crisis Explores the policies and practices used in formulating and transmitting monetary policiesQuestions fiscal-monetary connnections and encourages new thinking about the business cycle itself Observes changes in the formulation of monetary policies over the last 25 years
The principal concern of this book is to set out the elements that enter into problems of analyzing inflation. This detailed, readable review of contemporary theory on the problems of inflation fills an important gap in the literature on macro-economics that: 1) assesses the implications of inflationary processes for economic policy; 2) synthesizes a general framework within which to illustrate inflationary processes; 3) reconciles the approaches of "demand inflation" and "cost inflation"; and 4) analyzes the determination and behavior of the general price level in an exchange economy.
The first part of the book reviews neo-classical and "Keynesian" type models of the closed macro-economy, analyzes determination of the general price level, and introduces a restatement of conventional employment theory with emphasis on the general price level.
The second part considers the problems of price and wage determinations and the demand for money in more detail, synthesizing the analyses into a model of the macro-economy and discussing the implications of this model and the preceding analysis for economic policy. Describing alternative approaches to the theory of inflation, each of which has resulted in partial theories, the book avoids fragmentary explanations by setting the entire discussion in the context of a macro-economic general equilibrium framework.
