This book sheds new light on the general equilibrium theory of Léon Walras (1834–1910) from a historical perspective. Walras's construction of general equilibrium theory marked the dawn of modern economics, and the theory was greatly developed in the 20th century. However, Walras's own intentions and ideas behind the theory are still not fully understood.This book aims to clarify the intellectual background of Walras's economics by delving into his original writings, which have not received much attention until now. Part 1 of the book reconsiders the relationship between Walras and his predecessors, Adam Smith (1723–1790), Jean-Baptiste Say (1767–1832), and Achylle Nicolas Isnard (1749–1803), who are believed to have had a decisive influence on Walras's general equilibrium theory. In Part 2, the book explores Walras's views on the labor market, entrepreneurship, and non-selfish human nature, including concepts like sympathy, which have been overlooked in his general equilibrium theory and subsequently misunderstood to this day. Walras's economic thought is one of the foundational sources of modern economics. An accurate and in-depth understanding of it will provide a new perspective on the problems faced by modern economics and open future possibilities for economics as a social science. This book offers new insights not only to researchers and students of the history of economics but also to all those interested in the origins of modern economics.

This is the first book that uses the Harris – Todaro (H-T) model to study contemporary economic issues in developing countries, with a particular focus on China. The zenith of research utilizing this model occurred in the 1990s, primarily addressing the impact of economic policies during labor migration on wages and employment across various sectors, international trade, urban unemployment rates, and social welfare. After nearly four decades, research in this area gradually faded from the spotlight. Post-2010, however, there has been a resurgence in H-T model studies. Scholars have begun using this model to explore contemporary issues, revealing unprecedented insights and showcasing its robust applicability and vitality. The book features 13 papers authored by contributors since 2018, each utilizing the H-T model and published in various academic journals. It delves into pivotal issues of contemporary economic development in developing countries like China, including dual agricultural economy, producer services, foreign direct investment, agricultural pollution, migrant workers'remittances, and agricultural human capital investment. The book constructs general equilibrium models by integrating these topics with the H-T model, providing a framework to assess the impact of economic policies. Methodologically, it goes beyond conventional approaches by introducing constant elasticity of substitution functions and other methods to precisely express contemporary economic problems. Numerical simulations to examine the impact of economic policies are also used. Beyond presenting solutions to the current economic problems in developing countries, this book provides academic references for economic theory researchers.

Begrijp de essentie van de speltheorie (ook bekend als strategische gedragstheorie en interactieve beslissingstheorie) in slechts 50 minuten met dit praktische en beknopte boek. De speltheorie bestudeert de gevolgen van strategische interactie (namelijk onderhandeling, concurrentie en wederzijdse bijstand) tussen verschillende'spelers'die elk hun eigen doelen nastreven. Het toont duidelijk de onderlinge afhankelijkheid aan van bedrijven, landen en individuen en helpt ons de machtsverhoudingen in onderhandelingen te begrijpen, waardoor het waardevolle toepassingen heeft in de economie, conflictanalyse en besluitvorming. Dit boek biedt u een handige inleiding tot de complexiteit van sociale interacties en de praktische toepassingen van de speltheorie in een reeks domeinen. U leert niet alleen hoe u strategieën kunt toepassen in uw interacties met anderen, maar u behandelt ook een aantal voorbeelden, zoals het klassieke probleem van het dilemma van de gevangene, komt meer te weten over de tekortkomingen van het instrument, waaronder de relatieve moeilijkheid om het toe te passen op reële situaties, en leert over verwante modellen, zoals gezelschapsspellen en oneindige spellen. Over speltheorie : De oorsprong van de speltheorie gaat terug tot de Renaissance, toen de eerste analyses van strategiespellen verschenen, hoewel er geen formele theorie bestond tot de 19e en 20e eeuw. De theorie bestudeert sociale interactie en wil bewijzen dat individuen, bedrijven en landen onderling afhankelijk zijn. Bijgevolg is de gunstigste stap voor alle betrokkenen het vinden van een evenwicht dat alle partijen past. Hoewel samenwerking misschien niet de gemakkelijkste zaak van de wereld is, is de beste manier om met de noodzaak tot samenwerking om te gaan, deze te begrijpen en niet te bestrijden. In dit boek ontdekt u hoe de speltheorie u kan helpen, leert u hoe u deze kunt toepassen op verschillende gebieden, en gebruikt u uw resultaten om een passende strategie uit te werken. Een duidelijke uitleg van de voordelen en mogelijke nadelen van de methode, een bespreking van een praktische casus en een inleiding tot verwante modellen geven u de instrumenten die u nodig hebt om uw aanpak op uw situatie af te stemmen.

This book shows how such a computational process functions, how great is its power and versatility, since it is possible to show how discoveries are made. In 1759, A. Smith realized that there must exist an additional powerful control mechanism behind Great Britain's authority and government, explaining the extraordinary successes of Great Britain. He called this the Invisible Hand. Despite having used this term only 3 times, the idea evokes extreme scientific and political emotions to this day. If we apply a molecular model of computation, such as in in Adleman's DNA computer, a computational model for the Invisible Hand can be built to show how it affects a society. It is a spontaneous, unconscious, distributed, noncontinuous computational process on the platform of minds of, e.g., people or ants. Knowing this mechanism, a future self-steering and self-optimization system for AI robot teams can be proposed, e.g., for construction sites and rescue operations.

Revised and updated for the 2nd edition, this textbook provides an analysis and investigation of the most essential areas of environmental economic theory and policy, including international environmental problems. The approach is based on standard theoretical tools, in particular equilibrium analysis, and aims to demonstrate how economic principles can help to understand environmental issues and guide policymakers. Current topics including climate change, overfishing and integrated approaches to environmental policies are carefully analyzed in this framework, and a multitude of practical examples from various parts of the world is presented. Addressing undergraduate and graduate students, this book is a must read for everybody interested in a better understanding of environmental economics.

The new edition of a widely used introduction to game theory and its applications, with a focus on economics, business, and politics.This widely used introduction to game theory is rigorous but accessible, unique in its balance between the theoretical and the practical, with examples and applications following almost every theory-driven chapter. In recent years, game theory has become an important methodological tool for all fields of social sciences, biology and computer science. This second edition of Strategies and Games not only takes into account new game theoretical concepts and applications such as bargaining and matching, it also provides an array of chapters on game theory applied to the political arena. New examples, case studies, and applications relevant to a wide range of behavioral disciplines are now included. The authors map out alternate pathways through the book for instructors in economics, business, and political science. The book contains four parts: strategic form games, extensive form games, asymmetric information games, and cooperative games and matching. Theoretical topics include dominance solutions, Nash equilibrium, Condorcet paradox, backward induction, subgame perfection, repeated and dynamic games, Bayes-Nash equilibrium, mechanism design, auction theory, signaling, the Shapley value, and stable matchings. Applications and case studies include OPEC, voting, poison pills, Treasury auctions, trade agreements, pork-barrel spending, climate change, bargaining and audience costs, markets for lemons, and school choice. Each chapter includes concept checks and tallies end-of-chapter problems. An appendix offers a thorough discussion of single-agent decision theory, which underpins game theory.

For all its elaborate theories and models, economics always reduces to comparisons. Should we build A rather than B? Will I be better off if I eat D rather than C? How much will it cost me to produce F instead of E? At root, the ultimate goal of economics is simple: assessing the alternatives and finding the best possible outcome. This basic mathematical concept underlies all introductions to the field of economics, yet as advanced students progress through the discipline, they often lose track of this foundational idea when presented with real-world complications and uncertainty. In Competitive Agents in Certain and Uncertain Markets, Robert G. Chambers develops an integrated analytic framework for treating consumer, producer, and market equilibrium analyses as special cases of a generic optimization problem. He builds on lessons learned by all beginning students of economics to show how basic concepts can still be applied even in complex and highly uncertain conditions. Drawing from optimization theory, Chambers demonstrates how the same unified mathematical framework applies to both stochastic and non-stochastic decision settings. The book borrows from both convex and variational analysis and gives special emphasis to differentiability, conjugacy theory, and Fenchel's Duality Theorem. Throughout, Chambers includes practical examples, problems, and exercises to make abstract material accessible. Bringing together essential theoretical tools for understanding decision-making under uncertainty, Competitive Agents in Certain and Uncertain Markets provides a unified framework for analyzing a broad range of microeconomic decisions. This book will be an invaluable resource for advanced graduate students and scholars of microeconomic theory.

Understanding Economic Equilibrium reveals how all markets fit together, and how we as individuals fit into that bigger picture.Economic agents all over the world are trying to maximize their returns given their efforts, resources, and opportunities. They come together in markets that ultimately allocate goods and services among many competing interests. We can readily see how individual markets behave; it's more difficult, but exponentially more important, to recognize the general equilibrium across all markets. Disturbances in one market have implications for others.These interrelationships are particularly important to understand when policy changes are being considered where actions in one market will impose changes on other markets, and not always in obvious or pleasant ways. Understanding Economic Equilibrium reveals how all markets fit together, and how we as individuals fit into that bigger picture.

Synthesising Marx's, Keynes's and Schumpeter's theories on wage-price dynamics, effective demand, real innovations and financial markets into a coherent whole, this book goes significantly beyond a consideration of their work in isolation. It focuses on exploring and analysing Goodwin's integrated Marx-Keynes-Schumpeter system (MKS), approaching this from a historical perspective.Chapters start from Harrod's and Kaldor's work, reconsidering prominent demand- and supply-side approaches to Keynesian macro-dynamics, supplemented by Goodwin's distributive cycle. The book presents a baseline MKS-type model, considering the rigorous treatment of uncertainty, opinion dynamics, the movement from flexicurity to social capitalism and democracy, and a high-order MKS macro-model.The exploration of the MKS model from a historical basis will make this a useful book for macroeconomics and history of economics scholars and students. It will also be helpful for those looking at macrodynamics in more depth.

Esta obra se centra en el análisis de la microeconomía del equilibrio general, la cual involucre varios agentes y mercados, que permiten ampliar las consideraciones de la economía, como un todo, incluso la demanda y la oferta individuales y agregadas, para varios mercados, de manera simultánea. El texto busca acercarse a los estudiantes de pregrado en Economía de una manera diferente, no solo desde la teoría sino por medio de las aplicaciones matemáticas, que incentiven el estudio y la investigación de los diferentes mercados, tan importantes para la sociedad actual, no solo en la provisión de bienes y servicios y desde la noción del equilibrio, sino en la reducción de las brechas del conocimiento existentes en temas considerados “enigmáticos”.

This book addresses major issues such as a growing world energy demand, environmental degradation due to anthropogenic greenhouse gas (GHG) emission, and risk management of disastrous events such as pandemics, abnormal climate, and earthquakes. Using cutting-edge analytical tools, particularly computable general equilibrium (CGE) modelling, the analyses are focused on a very wide range of policy-relevant economic questions for the Asia-Pacific region, especially for Japan, China, India, Vietnam, and smaller nations, including Brunei, Timor Leste, and Fiji. The first part considers (a) the effects of climate change on agriculture sectors, energy policies, and future GHG emission trends, (b) adaptation to climate changes in energy policy and its impacts on the economies, and (c) risk management of catastrophic events such as global pandemics. The second part examines (a) energy environmental issues, (b) economic impacts of natural disaster and depopulation, and (c) effects of informatics development on risk management, using CGE modelling and other methods in regional science fields. Contributors are internationally active leading CGE modellers and environmental economists. The book should be greatly beneficial for scholars and graduate students as well as policy makers who are interested in the economic effects and management of risks relating to climate change and disastrous events.

In Monetary and Fiscal Policy Through a DSGE Lens, Harold L. Cole develops and extends versions of a classic quantitative model of economic growth to take on a wide range of topics in monetary and fiscal policy. Bridging the gap between current undergraduate and graduate texts in the field, this comprehensive book covers the basic elements of advanced macroeconomics and equips readers to understand the debate on key policy questions. By using the simple DSGE, or dynamic stochastic general equilibrium, framework to build a series of quantitative models, the book combines a gradual introduction to advanced analytic methods with computer programming and quantitative policy analysis. In a clear discussion of the sophisticated interaction between theory and data, Cole explains how to gauge how well a model captures key elements in the data and how to reverse engineer a model to data. The book covers costs of inflation, optimal monetary policy, the impact of labor and capital taxes, and optimal fiscal policy. It systematically discusses technical material including the new Keynesian liquidity shock models, standard analytic methods, such as Lagrangian methods, and computational methods using Matlab and Python. With a strong computational emphasis, the volume teaches how to program up and solve systems of non-linear equations and develop models to study the macroeconomy. Knowing how to deeply understand and analyze models and develop computational code to evaluate the implications of those models is essential for students of macroeconomics. This book connects the standard undergraduate material to the elaborate models of advanced graduate courses with systematic and logical coverage of the basics of advanced modern macroeconomics.

This book provides a comprehensive introduction to general equilibrium theory, covering the standard topics as well as the developments of the theory over the past fifty years. This ensures that the reader gains a thorough account of what has been established both in pure theory and in applications.In addition to the basic topics, this book elaborates on fields which are relevant but not mentioned frequently in this context. The material covered includes international trade, growth, finance and implementation, and it offers a broader view than what is usual in texts on general equilibrium theory. This book would make for suitable reading for undergraduate and graduate courses in macroeconomics.

The birth and death of firms is one of the main features of the business cycle. Yet mainstream DGSE macroeconomic models mostly ignore this phenomenon, thereby excluding any potential impact of economic policy on the probability of the birth and death of firms. Those DGSE models that do allow for this phenomenon do so at the cost of drastic simplifications, which effectively rule out causal links between the strategic interaction of industrial firms and the macroeconomy. This innovative new book develops a bottom-up, agent-based framework that shows how strategic interactions at the level of oligopolistic firms, and even at the level of individuals, affect entire industrial sectors and the equilibrium of the macroeconomy. It will appeal to academic researchers and graduate students working in computational economics, agent-based modelling and econophysics, as well as mainstream economists interested in learning more about alternatives to DGSE models in macroeconomics.

It is impossible to understand modern economics without knowledge of the basic tools of gametheory and mechanism design. This book provides a graduate-level introduction to the economic modeling of strategic behavior. The goal is to teach Economics doctoral students the tools of game theory and mechanism design that all economists should know.

This book is for people who want to understand modern trade theory, particularly the Melitz model. It lays out Melitz theory from first principles and relates it to earlier theories of Armington and Krugman. For trade theory specialists, the book produces some significant conclusions. It identifies conditions under which Krugman and Melitz models produce essentially the same results for the welfare effects of trade liberalization as those obtained from Armington, and conditions under which this is not true. These findings will be of interest to academics and policy advisors who need to understand critiques of Armington by proponents of Krugman and Melitz.For computable general equilibrium (CGE) modelers, the book shows how Melitz-style CGE models can be calibrated, solved and interpreted. A major practical contribution of the book is to show how large-scale Armington models such as GTAP can be converted to Melitz by the addition of a small number of equations and minimal alteration of the original Armington model.The book describes computational experience in solving Melitz CGE models using GEMPACK software. This experience will be of interest to researchers currently attempting to solve Melitz-based CGE models. Almost all previous Melitz studies have used GAMS software. Authors of these studies have reported computational difficulties. These difficulties did not occur in this book's GEMPACK-based computations. The book concludes that: (a) CGE modelers can embrace Melitz while retaining their Armington-based models as powerful interpretive devices; and (b) via GEMPACK, large-scale CGE models incorporating Melitz specifications can be solved with no more difficulty than similar-dimensioned Armington models.

This book attempts to elucidate the views of Keynes's General Theory as far as equilibrium, expectations and information are concerned, and compares them with those of modern classical economists of the Chicago and Ricardian persuasion.

This book discusses mathematical models for various applications in economics, with a focus on non-linear dynamics. Based on the author's over 50 years of active work in the field, the book has been inspired by models from the period between 1920 and 1950. Following a brief introduction to economics for mathematicians and other modelers, it assembles a repository of useful specific functions for global dynamic modeling. Furthermore, twelve “research stubs” – outlined research agendas that have not yet been fully worked on – are suggested for further study and could even be expanded to entire research projects. The book is a valuable resource, particularly for young scientists who are skilled in mathematical and computational techniques and are looking for applications in economics.

This book mainly addresses the general equilibrium asset pricing method in two aspects: option pricing and variance risk premium. First, volatility smile and smirk is the famous puzzle in option pricing. Different from no arbitrage method, this book applies the general equilibrium approach in explaining the puzzle. In the presence of jump, investors impose more weights on the jump risk than the volatility risk, and as a result, investors require more jump risk premium which generates a pronounced volatility smirk. Second, based on the general equilibrium framework, this book proposes variance risk premium and empirically tests its predictive power for international stock market returns.

This essential volume reflects the continuing and enduring utility of general equilibrium as a framework of analyses. It attempts to reiterate that understanding broad and holistic consequence of economic events and policies go beyond partial equilibrium perspective. Cutting across areas of research, general equilibrium perspectives in terms of small-scale GE models following the theory and perspectives of Ronald Jones can help readers develop informed judgement regarding critical policies. These include but are not limited to several areas of specific interest - the interaction of financial factors with international trade and implications for the'real sectors'of the economy, the impact of labour market reforms on the unorganised sectors in developing and transition countries, the non-uniform effects of inflation and deflation on internal and external factor flows, and the sought-after relation between foreign investment and skill accumulation.

This title, first published in 1984, considers a temporary monetary equilibrium theory under certainty in a differentiable framework. Using the techniques of differential topology the author investigates the structure of the set of temporary monetary equilibria. Temporary Monetary Equilibrium Theory: A Differentiable Approach will be of interest to students of monetary economics.

The concept of equilibrium is fundamental to economic theory, according to which, it exists when supply and demand are balanced. Equilibrium Models in Economics critically examines the major problematic assumptions employed to build equilibrium models. It gives particular attention to the assumptions used to characterize learning, knowledge and expectations. Lawrence Boland here explores whether equilibrium models can provide a realistic explanation of economic events and objects such as prices, market demands and market supplies. He traces how the different perspectives on equilibrium models represented by such creators as Kenneth Arrow, Robert Clower, and George Richardson influenced subsequent developments in economics. A key debate is about the comparative importance of whether equilibrium refers to a state of an actual economy or a property of a formal mathematical model. Another is the extent that the distinction between a model's exogenous vs. endogenous variables involves causality. Also explored are more recent efforts provided by behavioral, evolutionary, and complexity economics-whether they might change how economics is practiced in the future and how they could. Equilibrium Models in Economics is a trenchant exploration of how the discipline has grappled with attempts to understand and explain the way information, knowledge, and the expectations of actors participating in the economy influence outcomes and behavior. It presents a realistic, workable theory of knowledge and learning, simulating how decision makers and other actors operate in fast-changing equilibrium conditions.

This book addresses the gaps in undergraduate teaching of partial equilibrium analysis, providing a general equilibrium viewpoint to illustrate the assumptions underlying partial equilibrium welfare analysis. It remains unexplained, at least at the level of general economics teaching, in what sense partial equilibrium analysis is indeed a part of general equilibrium analysis. Partial equilibrium welfare analysis isolates a market for a single commodity from the rest of the economy, presuming that other things remain equal, and measures gains and losses by means of consumer surplus. This is a money metric that is supposed to be summable across individuals, recommending policy that maximizes the social surplus. But what justifies such apparently uni-dimensional practise? Within a general equilibrium framework, the assumption of no income effect is presented as the key condition, and substantive general equilibrium situations in which the condition emerges are presented. The analysis is extended to the case of uncertainty, in which the practice adopts aggregate expected consumer surplus, and scrutinizes when such practice is justified. Finally, the book illustrates partial equilibrium as an institutional artifact, meaning that institutional constraint induces individuals to behave as if they are in partial equilibrium. This volume forms an important contribution to the literature by researching why this disparity persists and the implications for economics education.

This is a new kind of textbook in microeconomic theory. In place of the usual concentration on partial equilibrium analysis and discussion of a standard series of topics, the authors seek to introduce the student from the start to the general equilibrium approach to microeconomics, in the form of the two-sector model. This model is then applied to a variety of subjects in different special fields of economic analysis: welfare economics, international trade, public finance and income distribution. This book represents a very different approach to the teaching of micro-economic theory than normally followed, and one that will be of greater long-run value to the serious student of economics. In place of the usual textbook development of the subject as traditionally conceived through topics of increasing complexity and analytical difficulty, using partial equilibrium techniques of analysis, the book concentrates on the exposition and application of a more logically integrated set of tools that have been found of greater use in the analysis of problems arising not only in traditional micro-economics but also in a number of fields of economics that have customarily been hived off into separate specialized advanced courses. General Equilibrium Analysis starts with the description of the two-sector model and how these two sectors are built based on the individual micro-units in which they made up of and how they fit into the concept of the circular flow of income. Subsequent chapters deal with the evaluation of changes in factor endowment, demand preferences and technical progress by means of the model; and the theory of government, which includes both the theory of government expenditure, or public goods, and the theory of government tax and/or subsidy programmes-changes in budgetary scale, tax substitution and expenditure substitution. The model is then extended to an open economy-the so-called'two by two by two'--to consider both the normative effect of inte

The financial crisis of 2007 and the following recession present a major challenge to macroeconomic theory. The same holds true for exceptionally low interest rates during the recent years and for the puzzle that super-expansive monetary policies failed to produce high inflation. Approaches that focus on steady states, rational expectations, and individuals planning over infinite horizons, are not suitable for analysing such abnormal situations. A Study in Monetary Macroeconomics refines and improves mainstream approaches to resolve these puzzles and to contribute to a better understanding of monetary and fiscal policies. Using a rich institutional structure that includes features such as credit money, external finance, borrowing constraints, net worth, real estate and commercial banks, this timely study reduces rationality requirements to cope with its complex setting. It starts with a simple baseline model, deriving results from mathematical reasoning and simulations whilst adhering to the method of dynamic general equilibrium (DGE) with optimizing agents and fully specified models. Highly topical, A Study in Monetary Macroeconomics uses a unified theoretical framework to demonstrate that a DGE approach makes it possible to develop clean models that work outside steady states and are appropriate for answering macroeconomic questions of actual interest.

This title, first published in 1984, is a contribution to applied international trade theory. The author explores the specification and estimation of a multisector general equilibrium model of the open economy. The model is formulated with the aim of assessing empirically the effects of three key policy variables on trade flows, domestic prices, and the trade balance. The policy variables with which the author is concerned are the rate of growth of the stock of domestic credit, commercial policy, as represented by tariffs, and, finally, the exchange rate. This title will be of interest to students of economics.

This study, first published in 1979, continues by examining the question of whether a competitive economy can efficiently allocate a stock of non-renewable natural resources through time. Long-run analyses of competitive economies with such resources have concluded that, without perfect foresight or a complete set of future markets extending infinitely far into the future, there is no economic mechanism to guarantee that the initial price is set so that the economy converges to the socially desirable path of balanced growth. This title will be of interest to students of environmental and natural resource economics.

Europe's and Latin America's social and economic stagnation is a direct result of the unresolved phenomena of the financialization crisis that broke in 2008 in developed countries. Editors Noemi Levy and Etelberto Ortiz analyze the limitations of economic growth and development under capitalist economic organizations where financial capital is dominant as well as explore alternate economic policies.This book argues that institutional settings based on the international monetary market, the global production organization, and the international commerce arraignments need to be redesigned to improve countries'economic growth, job opportunities, and salaries. In order for economic disequilibria to be reduced among regions, countries, and social classes, economic surplus appropriation must be regulated. Divided into four distinct thematic sections, the chapters discuss how income distribution must be re-evaluated in order to halt the economic crisis of developing countries in Europe and Latin America and to boost a new cycle of economic growth and development.This critical discussion will be of value to economic scholars and researchers, policy makers wishing to learn more about the limitations of economic growth, as well as journalists specializing in economic issues.Contributors include: A.

The authors present a new formal framework for finding the long-run competitive market equilibrium through short-run equilibria by exploiting the operating policies and plant valuations. This “short-run approach” develops ideas of Boiteux and Koopmans. Applied to the peak-load pricing of electricity generated by thermal, hydro and pumped-storage plants, it gives a sound and practical method of valuing the fixed assets—in this case, the river flows and the geological sites suitable for reservoirs. Its main mathematical basis is the producer's short-run profit maximization programme and its dual; their solutions have relatively simple forms that can greatly ease the fixed-point problem of solving for the general equilibrium. Since the optimal values (profit and cost functions) are usually nondifferentiable—this is so when there are joint costs of production such as capacity constraints—nonsmooth calculus is employed to resolve long-standing discrepancies between textbook theory andindustrial reality by giving subdifferential extensions of basic results of microeconomics, including the Wong-Viner Envelope Theorem.

This book aims to explore stability in an international financial system using disequilibrium theory. It examines historical cases of both instability and stability and reviews price-disequilibrium theory to construct a theoretical model for a stable international financial system. In the modern knowledge economy in a global world, financial socio-technical systems still continue to be central to global commerce. Moreover, technological advances in computer and communications have changed both the knowledge economy and the financial system. While globalization and technology have made international finance more powerful and important to knowledge economies, they have also increased the volatility, instability, and fraudulent use of international finance. The international world has not experienced a long-term, stable financial system after 1913. International financial systems have been periodically unstable, triggering financial crises and resultant economicdepressions in different nations. Yet the global economy cannot develop properly without a stable international system, which distributes wealth to economically productive activities. How then can a stable and modern international-financial-system be constructed? In this provocative volume, the authors applies the cross-disciplinary analysis of societal dynamics to important economic writers to derive a new approach to the problem of stabilizing international financial systems.

Andreu Mas-Colell revolutionized our understanding of competitive markets, price formation, and the behavior of market participants. General Equilibrium and Game Theory offers readers a compendium of his most important scholarly contributions, gathering in a single volume the groundbreaking papers that have solidified his standing as one of the preeminent economic theorists of our time.Built upon the foundations of neoclassical economics, Mas-Colell's work is distinguished by a mathematical and analytical elegance that brings theory closer to real-world situations. He overturns the standard assumption of general equilibrium theory—that markets are perfectly competitive and their participants are perfectly rational—and concludes that neither the law of supply and demand nor the existence of equilibrium prices depends on the rationality of agents. Similarly, Mas-Colell (working with Sergiu Hart) challenges classical game theory's reliance on rational behavior, demonstrating that adaptation and learning shape the dynamics of repeated games.Addressing central questions of finance, trade, industrial organization, and welfare economics, Mas-Colell shows the surprising power and versatility of differentiability and linear-space mathematical techniques, and he emphasizes the fruitfulness of cooperative game-theory approaches, such as Shapley value theory and the Bargaining Set, for understanding competition and distribution. General Equilibrium and Game Theory is a signal contribution to economic theory and an invaluable resource for anyone wishing to study the craft of a master of economic modeling.

The economic theory of general equilibrium underpins the most important models used in economic theory in general and in its more specialized areas such as macroeconomics, international trade, environmental economics, growth theory, and developmental economics. In Foundations of the Theory of General Equilibrium, leading academic scholar, Yves Balasko offers a good introduction to the economic theory of general equilibrium and makes use of various mathematical tools as intuitive and easy as possible. The second half of the book addresses properties of the general equilibrium model that are still at the frontier of current research. These properties deal with the characterization of economies with a unique equilibrium and, more generally, with the relationships between the number of equilibria and the fundamentals of an economy.

This book offers an introductory step-by-step course in Dynamic Stochastic General Equilibrium (DSGE) modelling. Modern macroeconomic analysis is increasingly concerned with the construction, calibration and/or estimation and simulation of DSGE models. The book is intended for graduate students as an introductory course to DSGE modelling and for those economists who would like a hands-on approach to learning the basics of modern dynamic macroeconomic modelling. The book starts with the simplest canonical neoclassical DSGE model and then gradually extends the basic framework incorporating a variety of additional features, such as consumption habit formation, investment adjustment cost, investment-specific technological change, taxes, public capital, household production, non-ricardian agents, monopolistic competition, etc. The book includes Dynare codes for the models developed that can be downloaded from the book's homepage. The second edition is identical to the first with the exception of a revised appendix to Chapter 2. The revised appendix can be downloaded free of charge in the accompanying downloads section.

Policies affecting resource allocation across tradable sectors and those affecting the incentives to produce tradable activities are key determinants of macroeconomic balance and growth. Computable general equilibrium models have made significant contributions to both types of policies. With advancements in computing power and software, these models have become easy to implement and are now widespread. The question then is when and how to formulate them to avoid the ‘black box'syndrome.This book seeks to address these issues through carefully selected essays that analyse how to model general equilibrium linkages in a single economy, across developing and developed economies, and across both micro and macro policies. Micro policies examined include tariffs quotas and VERs, the choice of taxes to maximize government revenue, migration and remittances, and the political economy of tariff setting. Applications on macro policies cover capital inflows, real exchange rate determination, and the modeling of the effects of adjustment policies on income distribution.The book provides insights on the development of a family of models for diverse policy choices, focusing on the ways to model the following: links between tradable and non-tradable activities, labor markets, and portfolio choices given limited capital mobility. Selected essays are all inspired by specific policy problems, including the adaptation to external shocks (i.e. oil), consequences of capital inflows, determinants of migration and associated remittances, the productivity of foreign aid, and rent-seeking activities under trade regimes with non-price trade restrictions. Examples in this book lay out the theoretical foundations, alongside a variety of applications, to help formulate coherent and transparent models for policy analysis. Archetype economies are extensively used to show how differences in economic structure influence the effects of policies. Graduate students and policy analysts interested in modeling will find this a useful compendium of studies.

First Published in 1994. Nicholas Kaldor was born in Hungary in 1908 and died as Baron Kaldor of Newnham in the City of Cambridge, England, in 1986. The years between revealed no hint of scandal or psychological problems that might make Kaldor the subject of a novel. His life was, instead, a straight line of growth and achievement, of intellectual enjoyment and strong values. Kaldor's struggles were intellectual-namely, his efforts to comprehend the economics of the real world, to fit this understanding into economic theory, and to convince his fellow citizens and economists of the accuracy of his perceptions. Kaldor forces us to ponder what the relationship between economic theory and practice should be.

Questo è il terzo tomo di una trilogia: I. Differenziazione, non linearità, equilibrio (2006); II. Stati psichici e costanti dell'azione (2013). In questo terzo tomo si procede all'applicazione della teoria delle derivazioni, alla ricerca delle variabili dell'azione. Come per gli altri due tomi, si parte sempre dal testo paretiano, estendendone esempi ed osservazioni tratti soprattutto dalla contemporaneità. Uno sguardo da vicino, dunque, anche in questo tomo. Stampa quotidiana, periodica, libri e osservazioni dirette sono stati fonti inesauribili per l'individuazione delle derivazioni. Il risultato è che dalle migliaia di esempi selezionati ne sono stati estratti circa quattrocentocinquanta, divenuti parte integrante di questo volume. Come per il precedente, ognuno potrà sostituire un qualsiasi esempio con un altro di apparente segno opposto, non muta il risultato: la potenza delle derivazioni staccatesi dalle pulsioni (residui) è tale da «portare opposte dottrine allo stesso punto»; poiché, in realtà, non le azioni o i fatti concreti sono stati classificati e discussi, ma i loro elementi (sentimenti o stati psichici), i quali permettono di completare una teoria sociologica della mente.

En estos apuntes de clase se explica de manera detallada cómo se determina la demanda agregada (DA) en una economía cerrada, utilizando como marco conceptual la teoría keynesiana y el modelo IS-LM, elaborado por John Hicks en 1937 y Alvin Hansen. Es una interpretación de los conceptos desarrollados en los textos de macroeconomía, explicados de una manera sencilla; mediante la interpretación y construcción paso a paso de fórmulas, se busca que los alumnos de macroeconomía comprendan el funcionamiento de las políticas fiscal y monetaria, y sus efectos en la producción y renta. En la interpretación se utilizó simultáneamente el análisis gráfico, el matemático y el teórico. Inicialmente se presentan unas generalidades que sirven de sustento teórico; en el capítulo dos se estudia el mercado de bienes y servicios sin la influencia de la tasa de interés, y se hace hincapié en los principales agregados macroeconómicos de consumo, ahorro, inversión, ahorro y gasto público, y la influencia que tiene la política fiscal en la economía. En el capítulo tres se encuentra el equilibrio en el mercado de bienes y servicios teniendo en cuenta las tasas de interés, lo que deriva en la construcción de la IS. A continuación dentro de este mismo capítulo se trabaja el mercado de activos, se halla el equilibrio en el mercado monetario o curva LM y se estudia la influencia de la política monetaria. Lo anterior permite paso seguido encontrar simultáneamente el equilibrio en los mercados de bienes y monetario, y finalmente derivar la curva DA.
