With the collapse of the Bretton Woods system, any pretense of a connection of the world's currencies to any real commodity has been abandoned. Yet since the 1980s, most central banks have abandoned money-growth targets as practical guidelines for monetary policy as well. How then can pure "fiat" currencies be managed so as to create confidence in the stability of national units of account? Interest and Prices seeks to provide theoretical foundations for a rule-based approach to monetary policy suitable for a world of instant communications and ever more efficient financial markets. In such a world, effective monetary policy requires that central banks construct a conscious and articulate account of what they are doing. Michael Woodford reexamines the foundations of monetary economics, and shows how interest-rate policy can be used to achieve an inflation target in the absence of either commodity backing or control of a monetary aggregate. The book further shows how the tools of modern macroeconomic theory can be used to design an optimal inflation-targeting regime--one that balances stabilization goals with the pursuit of price stability in a way that is grounded in an explicit welfare analysis, and that takes account of the "New Classical" critique of traditional policy evaluation exercises. It thus argues that rule-based policymaking need not mean adherence to a rigid framework unrelated to stabilization objectives for the sake of credibility, while at the same time showing the advantages of rule-based over purely discretionary policymaking.

My original intention in writing this book was to consider evolving mar­ ket systems and Hayekian criteria of efficiency (see von Hayek (1931, 1945) ), and to discover those formal structures which might possibly lie at the base of economic systems capable of evolution. Much work in this field had already been done by others (see, for example, Kirzner (1975) and Nelson/Winter (1982) ), and a consensus seems to have been reached that something like system theory must be the logical point of departure for evolutionary theory in economics. But most of the previous work in this area is purely intuitive, and though there is much talk in it of systems and system theory, a precise definition of the concept of a system in this context is nowhere to be found. I had hoped to be able to sketch a working definition of pricing and production systems in a few pages and then to go on to investigate their performance within the framework of modern stability analysis. It soon became clear, however, that difficult and complex problems arise from the very outset of such an endeavor. If, for example, one speaks of dynamic systems of pricing and production, it should be made clear just how these systems differ from those portrayed in standard price theory and why that theory is inadequate for such analysis.

A deep-dive into the heart of modern financial markets, the authors explore why and how people trade - and the consequences.

First published in 1960, Interest Rates and Asset Prices presents an analysis of the determination of interest rates and asset prices with the help of few simple assumptions. The theory can be regarded either as an alternative to the liquidity preference theory or as an extension of it. Like that theory, it is aggregative and simple, but it is applicable not only to interest rates on government securities but also to yields on real assets. Furthermore, it can be formulated in terms of actually measurable variables, so that it is directly applicable to particular situations. This is demonstrated by a statistical example relating to the average yield on U.S. Government securities in the post- war period. In addition to the main analysis the author discusses the role of financial intermediaries and the structure of interest rates, and there is also a re-examination of the determinants of the transactions demand for money. This is book is an essential read for students of economics.
