Essays In The Face Of Uncertainies

The compendium of papers in this volume focuses on aspects of economic uncertainty, financial instabilities and asset bubbles.Economic uncertainty is modeled in continuous time using the mathematical techniques of stochastic calculus. A detailed treatment of important topics is provided, including the existence and uniqueness of asymptotic economic growth, the modeling of inflation and interest rates, the decomposition of inflation and its volatility, and the extension of the quantity theory of money to allow for randomness.The reader is also introduced to the methods of chaotic dynamics, and this methodology is applied to asset pricing, the European equity markets, and the multi-fractality in foreign currency markets.Since the techniques of stochastic calculus and chaotic dynamics do not readily accommodate the presence of stochastic bubbles, several papers discuss in depth the presence of financial bubbles in asset prices, and econometric work is performed to link such bubbles to monetary policy.Finally, since bubbles often burst rather than deflate slowly, the last section of the book studies the crash of October 1987 as well as other crashes of national equity markets due to the Persian gulf crisis.

Professor Dreze is a highly respected mathematical economist and econometrician. This book brings together some of his major contributions to the economic theory of decision making under uncertainty, and also several essays. These include an important essay on 'Decision theory under moral hazard and state dependent preferences' that significantly extends modern theory, and which provides rigorous foundations for subsequent chapters. Topics covered within the theory include decision theory, market allocation and prices, consumer decisions, theory of the firm, labour contracts, and public decisions.

Originally published in 1968, these ten essays by one of Europe’s leading sociological theorists deal with important issues on the borderline between sociology and social philosophy and demonstrate the author’s deep insight into history and political analysis. The author maintains that the structures of power in which the political process takes place not only originate change and give it direction, but also produce the fertile conflicts that give expression to the fundamental uncertainty of human existence. Through an examination of various concepts inherent in this dynamic process – power, resistance, conflict, change, freedom, uncertainty – a coherent theory of society emerges.

This volume honors Emanuel T. Weiler, the founder and first dean of Purdue University's School of Management and of the Krannert Graduate School of Management. Beginning in the mid-1950s, Weiler created a unique academic environment within which innovative and lasting contributions were made to both the teaching and content of economics and management. Members of the original economics faculty recruited by Weiler as well as several of their students wrote this collection of essays. All but one of the papers were prepared expressly for the volume and have not been published previously. The essays cover diverse areas which evolved from Weiler's leadership. The work has four major topical divisions (Economic Theory, Applied Economics, Macroeconomics, and Economics Education) plus a section of four memoirs.

This important new book introduces, analyzes and takes forward a post-Keynesian theory of the firm. It makes a vital contribution to the conceptualisation of uncertainty that is consistent with the methodological presuppositions of Post Keynesian economics. The author attempts to make a positive contribution to the development of Post Keynesian economics by refuting allegations of incoherence, detailing some of the salient implications of a transmutable conception of economic processes and then starting to explore what this means for how Post Keynesians conceptualise uncertainty. The book argues that the Post Keynesian distinctive view of time, understood as a non-deterministic open systems process, is a core and defining characteristic which is linked to its theoretical discussion of money and the principle of effective demand. Covering areas such as the coherence of Post Keynesianism, the future of Post Keynesian economics and Keynesian methodological debates, this book is useful reading for all Post Keynesian scholars with a strong interest in economic methodology and the philosophical underpinnings of economics.

These three elegant essays develop principles central to the understanding of the diverse ways in which imperfect information affects the distribution of resources, incentives, and the evaluation of economic policy. The first concerns the special role that information plays in the allocation process when it is possible to improve accuracy through private investment. The common practice of hiring "experts" whose information is presumably much better than their clients' is analyzed. Issues of cooperative behavior when potential group members possess diverse pieces of information are addressed. Emphasis is placed on the adaptation of the "core" concept from game theory to the resource allocation model with differential information. The second essay deals with the extent to which agents can influence the random events they face. This is known as moral hazard, and in its presence there is a potential inefficiency in the economic system. Two special models are studied: the role of moral hazard in a monetary economy, and the role of an outside adjudicatory agency that has the power to enforce fines and compensation. The final essay discusses the problem of certainty equivalence in economic policy. Conditions under which a full stochastic optimization can be calculated by solving a related, much simpler "certainty equivalence" problem are developed. The reduction in the complexity of calculation involved is very great compared with the potential loss of efficiency.

“[A] landmark book . . . Solnit illustrates how the uprisings that begin on the streets can upend the status quo and topple authoritarian regimes” (Vice). A book as powerful and influential as Rebecca Solnit’s Men Explain Things to Me, her Hope in the Dark was written to counter the despair of activists at a moment when they were focused on their losses and had turned their back to the victories behind them—and the unimaginable changes soon to come. In it, she makes a radical case for hope as a commitment to act in a world whose future remains uncertain and unknowable. Drawing on her decades of activism and a wide reading of environmental, cultural, and political history, Solnit argues that radicals have a long, neglected history of transformative victories, that the positive consequences of our acts are not always immediately seen, directly knowable, or even measurable, and that pessimism and despair rest on an unwarranted confidence about what is going to happen next. Now, with a moving new introduction explaining how the book came about and a new afterword that helps teach us how to hope and act in our unnerving world, she brings a new illumination to the darkness of our times in an unforgettable new edition of this classic book. “One of the best books of the 21st century.” —The Guardian “No writer has better understood the mix of fear and possibility, peril and exuberance that’s marked this new millennium.” —Bill McKibben, New York Times–bestselling author of Falter “An elegant reminder that activist victories are easily forgotten, and that they often come in extremely unexpected, roundabout ways.” —The New Yorker
