Money, Payments, and Liquidity, second edition


Book Description

A new edition of a book presenting a unified framework for studying the role of money and liquid assets in the economy, revised and updated. 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.




A Search-based Theory of the On-the-run Phenomenon


Book Description

We propose a model in which assets with identical cash flows can trade at different prices. Infinitely-lived agents can establish long positions in a search spot market, or short positions by first borrowing an asset in a search repo market. We show that short-sellers can endogenously concentrate in one asset because of search externalities and the constraint that they must deliver the asset they borrowed. That asset enjoys greater liquidity, measured by search times, and a higher lending fee ("specialness"). Liquidity and specialness translate into price premia that are consistent with no-arbitrage. We derive closed-form solutions for small frictions, and can generate price differentials in line with observed on-the-run premia.




Inflation Expectations


Book Description

Inflation is regarded by the many as a menace that damages business and can only make life worse for households. Keeping it low depends critically on ensuring that firms and workers expect it to be low. So expectations of inflation are a key influence on national economic welfare. This collection pulls together a galaxy of world experts (including Roy Batchelor, Richard Curtin and Staffan Linden) on inflation expectations to debate different aspects of the issues involved. The main focus of the volume is on likely inflation developments. A number of factors have led practitioners and academic observers of monetary policy to place increasing emphasis recently on inflation expectations. One is the spread of inflation targeting, invented in New Zealand over 15 years ago, but now encompassing many important economies including Brazil, Canada, Israel and Great Britain. Even more significantly, the European Central Bank, the Bank of Japan and the United States Federal Bank are the leading members of another group of monetary institutions all considering or implementing moves in the same direction. A second is the large reduction in actual inflation that has been observed in most countries over the past decade or so. These considerations underscore the critical – and largely underrecognized - importance of inflation expectations. They emphasize the importance of the issues, and the great need for a volume that offers a clear, systematic treatment of them. This book, under the steely editorship of Peter Sinclair, should prove very important for policy makers and monetary economists alike.




Economic Dynamics, second edition


Book Description

The second edition of a rigorous and example-driven introduction to topics in economic dynamics that emphasizes techniques for modeling dynamic systems. This text provides an introduction to the modern theory of economic dynamics, with emphasis on mathematical and computational techniques for modeling dynamic systems. Written to be both rigorous and engaging, the book shows how sound understanding of the underlying theory leads to effective algorithms for solving real-world problems. The material makes extensive use of programming examples to illustrate ideas, bringing to life the abstract concepts in the text. Key topics include algorithms and scientific computing, simulation, Markov models, and dynamic programming. Part I introduces fundamentals and part II covers more advanced material. This second edition has been thoroughly updated, drawing on recent research in the field. New for the second edition: “Programming-language agnostic” presentation using pseudocode. New chapter 1 covering conceptual issues concerning Markov chains such as ergodicity and stability. New focus in chapter 2 on algorithms and techniques for program design and high-performance computing. New focus on household problems rather than optimal growth in material on dynamic programming. Solutions to many exercises, code, and other resources available on a supplementary website.




Social Design


Book Description

This book contains invited essays in memory of Leonid Hurwicz spanning a large area of economic, social and other sciences where the implementation or enforcement of institutions and rules requires the design of effective mechanisms. The foundations of these articles are set by social choice concepts; game theory; Nash, Bayesian and Walrasian equilibria; complete and incomplete information. Besides in-depth treatments of well-established parts of mechanism and implementation theory, contributions on novel directions deal, for instance, with a quantum approach to game and decision making under uncertainty; digitalization; and the design of block chain for trading. The outstanding competence and reputation of the authors reflect the appreciation of the fundamental contributions and the lasting admiration of the personality and the work of Leonid Hurwicz.




Financial Soundness Indicators for Financial Sector Stability in Viet Nam


Book Description

Financial soundness indicators (FSIs) are methodological tools that help quantify and qualify the soundness and vulnerabilities of financial systems according to five areas of interests: capital adequacy, asset quality, earnings, liquidity, and sensitivity to market risk. With support from the Investment Climate Facilitation Fund under the Regional Cooperation and Integration Financing Facility, this report describes the development of FSIs for Viet Nam and analyzes the stability and soundness of the Vietnamese banking system by using these indicators. The key challenges to comprehensively implementing reforms and convincingly addressing the root causes of the banking sector problems include (i) assessing banks' recapitalization needs, (ii) revising classification criteria to guide resolution options, (iii) recapitalization and restructuring that may include foreign partnerships, (iv) strengthening the Vietnam Asset Management Company, (v) developing additional options to deal with nonperforming loans, (vi) tightening supervision to ensure a sound lending practice, (vii) revamping the architecture and procedures for crisis management, and (viii) strengthening financial safety nets during the reform process.




Modern Macroeconomics


Book Description

A textbook that approaches modern macroeconomics through its microeconomic foundations, with an emphasis on financial market connections and policy applications. The modern study and analysis of macroeconomics begins by considering how microeconomic units—consumers and firms—make decisions, and then investigates how these choices interact to yield economy-wide outcomes. This innovative textbook takes this “modern” approach, teaching macroeconomics through its microeconomic foundations. It does so by adopting the representative agent paradigm. By modeling the representative consumer and the representative firm, students will learn to describe macroeconomic outcomes and consider the effects of macroeconomic policies. Unique in its coverage of monopolistic competition, financial markets, and the interaction of fiscal and monetary policy, Modern Macroeconomics is suitable for use in intermediate undergraduate, advanced undergraduate, and graduate level courses. The book first introduces the building blocks of macroeconomics, the heart of which is the representative consumer. It goes on to offer a brief history of macroeconomic thought, including supply-side economics, the Phillips curve, and the New Keynesian framework. It then covers two policy applications, monetary policy and the interaction of monetary and fiscal policy; optimal policy analysis for both the flexible price and the rigid price case; long-run steady states, treating the Solow growth framework and the neoclassical growth model; a search-and-matching framework for the analysis of unemployment; and the application of the tools of modern macroeconomics to “open economy,” or international macroeconomics. End-of-chapter problem sets enable students to apply the concepts they have learned. A separate Solutions Manual will be available for students to purchase. Teaching materials, including complete solutions and slides, will be available to qualified instructors.




Alternative Central Bank Credit Policies for Liquidity Provision in a Model of Payments


Book Description

I explore alternative central bank policies for liquidity provision in a model of payments. I use a mechanism design approach so that agents' incentives to default are explicit and contigent on the credit policy designed. In the first policy, the central bank invests in costly enforcement and charges an interest rate to recover costs. I show that the second best solution is not distortionary. In the second policy, the central bank requires collateral. If collateral does not bear an opportunity cost, then the solution is first best. Otherwise, the second best is distortionary because collateral serves as a binding credit constraint.
