The economic crisis is also a crisis for economic theory. Most analyses of the evolution of the crisis invoke three themes, contagion, networks and trust, yet none of these play a major role in standard macroeconomic models. What is needed is a theory in which these aspects are central. The direct interaction between individuals, firms and banks does not simply produce imperfections in the functioning of the economy but is the very basis of the functioning of a modern economy. This book suggests a way of analysing the economy which takes this point of view. The economy should be considered as a complex adaptive system in which the agents constantly react to, influence and are influenced by, ...
An exploration of how approaches that draw on evolutionary theory and complexity science can advance our understanding of economics. Two widely heralded yet contested approaches to economics have emerged in recent years: one emphasizes evolutionary theory in terms of individuals and institutions; the other views economies as complex adaptive systems. In this book, leading scholars examine these two bodies of theory, exploring their possible impact on economics. Relevant concepts from evolutionary theory drawn on by the contributors include the distinction between proximate and ultimate causation, multilevel selection, cultural change as an evolutionary process, and human psychology as a prod...
This volume documents in a unique manner the momentum the institutionalist, evolutionary research agenda has regained over the past two decades. The thought-provoking contributions come from prominent authors with a rather heterogeneous theoretical background. Nonetheless, they all convene in elaborating on issues that have always been at the core of the institutionalist agenda and show how these issues relate to cutting edge research in modern economics. Ulrich Witt, Max Planck Institute of Economics, Jena, Germany This excellent EAEPE Reader brings together a range of perspectives on the role of institutions in economics. It is very well structured, with parts on microeconomics, macroecono...
The General Equilibrium Model, developed over the last century and now referred to as the Arrow-Debreu Model, provides the basis for the great majority of modern economic models. A thorough familiarity with its structure is indispensable for every serious economist. Elements of General Equilibrium Analysis provides a clear and precise explanation of various aspects of the model, each of which is analysed by a leading authority in the field, including Gerard Debreu, Timothy Kehoe, Herbert Scarf, Jean-Jacques Herings, Thorsten Hens, Peter Hammond, Werner Hildenbrand and Alan Kirman. This book provides a concise account of basic concepts together with an analysis of recent developments and is aimed at final year undergraduate and graduate students, and at all economists interested in an authoritative account of the foundations of modern history.
“In some ways, the e?ect of achieving understanding is to reverse completely our initial attitude of mind. For everyone starts (as we have said) by being perplexed by some fact or other: for instance... the fact that the diagonal of a square is incommensurable with the side. Anyone who has not yet seen why the side and the diagonal have no common unit regards this as quite extra- dinary. But one ends up in the opposite frame of mind... for nothing would so much ?abbergast a mathematician as if the diagonal and side of a square were to become commensurable”. [Aristotele] This is the ?rst volume of a new series entitled “New Economic Windows”. Each volume in the series will, we hope, p...
Advanced Textbooks in Economics, Volume 6: Introduction to Equilibrium Analysis: Variations on Themes by Edgeworth and Walras focuses on the approaches developed and instituted by Edgeworth and Walras in the study of equilibrium analysis. The book first underscores exchange economies, core of a game, and large economies. Discussions focus on economies with a continuum of agents, Walras equilibrium, prices and demand, balancedness, and commodity space. The manuscript then ponders on limit theorems for the core and existence of competitive equilibria. Topics include equilibria without convexity of preferences, existence of equilibria for economies with convex preferences, individual demand, emergence of prices, asymptotic equal treatment for most, uniform boundedness of core allocations, and limit theorems for type and replica economies. The publication examines continuous, upper, and lower hemi-continuous correspondences, fixed point theorems, and separation of convex sets. The book is a vital source of data for economists and researchers interested in equilibrium analysis.
seventeen contributions reflecting the many diverse approaches in the field todayThese seventeen contributions take up the most recent research in game theory, reflecting the many diverse approaches in the field today. They are classified in five general tactical categories - prediction, explanation, investigation, description, and prescription - and wit in these along applied and theoretical divisions. The introduction clearly lays out this framework.
Pack your cutlass and blunderbuss--it's time to go a-pirating! The Invisible Hook takes readers inside the wily world of late seventeenth- and early eighteenth-century pirates. With swashbuckling irreverence and devilish wit, Peter Leeson uncovers the hidden economics behind pirates' notorious, entertaining, and sometimes downright shocking behavior. Why did pirates fly flags of Skull & Bones? Why did they create a "pirate code"? Were pirates really ferocious madmen? And what made them so successful? The Invisible Hook uses economics to examine these and other infamous aspects of piracy. Leeson argues that the pirate customs we know and love resulted from pirates responding rationally to pre...
Assembles three different strands of long memory analysis: statistical literature on the properties of, and tests for, LRD processes; mathematical literature on the stochastic processes involved; and models from economic theory providing plausible micro foundations for the occurrence of long memory in economics.
