The paper considers gains from international economic policy coordination when there is uncertainty concerning the functioning of the world economy, but also learning about the “true” model on the part of policymakers. The paper reports estimates of plausible alternative versions of a standard, two-country model. Activist policy (either coordinated or uncoordinated) may produce large welfare losses in the absence of learning, if policymakers believe in the wrong model; hence exogenous money targets and freely flexible exchange rates may be best. However, model learning (from observations on macroeconomic variables) causes coordinated policies to dominate activist uncoordinated policies or exogenous money targets.

We study the use of foreign exchange (FX) intervention as an additional policy instrument in an environment with learning, where agents infer the central bank policy rules from its policy actions. Under full information, a central bank focused on stabilizing output and inflation can achieve better outcomes by using FX intervention as an additional policy tool. Under policy uncertainty, where agents perceive that monetary policy may also have exchange rate stabilization goals, the use of FX intervention entails a trade-off, reducing output volatility while increasing inflation volatility. While having an additional policy tool is always beneficial, we find that the optimal magnitude of intervention is higher in monetary policy regimes with lower uncertainty. These results indicate that the benefits of using FX intervention as an additional stabilization tool are greater in regimes where monetary policy is credibly focused on output and inflation stabilization.

How should firms decide whether and when to invest in new capital equipment, additions to their workforce, or the development of new products? Why have traditional economic models of investment failed to explain the behavior of investment spending in the United States and other countries? In this book, Avinash Dixit and Robert Pindyck provide the first detailed exposition of a new theoretical approach to the capital investment decisions of firms, stressing the irreversibility of most investment decisions, and the ongoing uncertainty of the economic environment in which these decisions are made. In so doing, they answer important questions about investment decisions and the behavior of investment spending. This new approach to investment recognizes the option value of waiting for better (but never complete) information. It exploits an analogy with the theory of options in financial markets, which permits a much richer dynamic framework than was possible with the traditional theory of investment. The authors present the new theory in a clear and systematic way, and consolidate, synthesize, and extend the various strands of research that have come out of the theory. Their book shows the importance of the theory for understanding investment behavior of firms; develops the implications of this theory for industry dynamics and for government policy concerning investment; and shows how the theory can be applied to specific industries and to a wide variety of business problems.

Froyen and Guender have provided a thorough and careful analysis of optimal monetary policy over most of the range of theoretical models that have been used in modern macroeconomics. By providing a comprehensive and clear comparative framework they will help the student of monetary policy understand why there have been conflicting views of what policy makers should do. Central Banking In Optimal Monetary Policy Under Uncertainty, academicians and economists Richard T. Froyen and Alfred V. Guender have collaborated on presenting an informed and informative survey of optimal monetary policy literature arising during the 1970s and 1980s as a ground work for understanding current market and other economic influences on such germane issues as discretion versus commitment, target versus instrument rules, and the delegation of policy making authority within the private and public sectors. With meticulous attention to scholarship and objectivity. . . Optimal Monetary Policy Under Uncertainty is a thoughtful and thought-provoking body of work that is very strongly recommended for professional, academic, corporate and governmental economic reference collections and supplemental reading lists. Midwest Book Review Recently there has been a resurgence of interest in the study of optimal monetary policy under uncertainty. This book provides a thorough survey of the literature that has resulted from this renewed interest. The authors ground recent contributions on the science of monetary policy in the literature of the 1970s, which viewed optimal monetary policy as primarily a question of the best use of information, and studies in the 1980s that gave primacy to time inconsistency problems. This broad focus leads to a better understanding of current issues such as discretion versus commitment, target versus instrument rules, and the merits of delegation of policy authority. Casting a wide net, the authors survey the recent literature on the New Keynesian approach to optimal monetary policy in the context of the earlier literature. They emphasize the relationship between policy decisions and the information set available to the policymaker, a central focus of the earlier literature, obscured in much recent work. Optimal policy questions are considered in open as well as closed economy models and the often confusing terminology in the literature is sorted and clarified. Questions are considered within easily analysed models and the authors clearly show why these models lead to different (or equivalent) policy conclusions. Recent policy issues such as desirability of inflation targeting and the relative merits of target versus instrument rules are covered in detail. Economists in academia and in policymaking organizations who want to learn about recent developments in the area of optimal monetary policy, as well as graduate and advanced undergraduate students in macroeconomic and monetary economics, will find this volume a clear and thorough examination of the topic.

In the last twenty years, several periods of turmoil have shaped the financial and economic system. Many regulatory policies, such as Basel III, have been introduced to overcome further crises and scandals. In addition, monetary policy has experienced a transition from conventional to unconventional frameworks in most industrialized and emerging economies. For instance, turning to hedge and diversification of portfolios, commodities markets have attracted increasing interest. More recently, new forms of money have been introduced, such as virtual money. These changes have influenced governance features at both macro and micro levels. Therefore, calls for ethical and sustainable standards in financial and economic spheres have been growing since 2007.Financial and Economic Systems: Transformations and New Challenges provides readers with insights about future transformations and challenges for financial and economic systems. Prominent contributors focus on different aspects, providing a global overview of crisis implications. The book is split into four main areas: Changes in the Real Sphere, covering issues related to yields, risk, unconventional monetary policy, and macroprudential policy; Financial Markets and Macroeconomics, covering uncertainty in finance and economics; CSR, Sustainability and Ethical Finance, highlighting the emergence of corporate social responsibility; and Digitalization, Blockchain and FinTech and the consequences of these transformations on markets and economic systems.

We analyse the interaction between private agents? uncertainty about inflation target and the central bank's data uncertainty. In our model, private agents update their perceived inflation target and the central bank estimates unobservable economic shocks as well as the perceived inflation target. Under those two uncertainties, the learning process of both private agents and the central bank causes higher order beliefs to become relevant, and this mechanism is capable of generating high persistence and volatility of inflation even though the underlying shocks are purely transitory. We also find that the persistence and volatility become smaller as the inflation target becomes more credible, that is, the private agents' uncertainty about inflation target (and hence the bank's data uncertainty) diminishes.
