Macroeconomics From The Bottom Up

This book arose from our conviction that the NNS-DSGE approach to the analysis of aggregate market outcomes is fundamentally flawed. The practice of overcoming the SMD result by recurring to a fictitious RA leads to insurmountable methodological problems and lies at the root of DSGE models’ failure to satisfactorily explain real world features, like exchange rate and banking crises, bubbles and herding in financial markets, swings in the sentiment of consumers and entrepreneurs, asymmetries and persistence in aggregate variables, and so on. At odds with this view, our critique rests on the premise that any modern macroeconomy should be modeled instead as a complex system of heterogeneous interacting individuals, acting adaptively and autonomously according to simple and empirically validated rules of thumb. We call our proposed approach Bottom-up Adaptive Macroeconomics (BAM). The reason why we claim that the contents of this book can be inscribed in the realm of macroeconomics is threefold: i) We are looking for a framework that helps us to think coherently about the interrelationships among two or more markets. In what follows, in particular, three markets will be considered: the markets for goods, labor and loanable funds. In this respect, real time matters: what happens in one market depends on what has happened, on what is happening, or on what will happen in other markets. This implies that intertemporal coordination issues cannot be ignored. ii) Eventually, it’s all about prices and quantities. However, we are mostly interested in aggregate prices and quantities, that is indexes built from the dispersed outcomes of the decentralized transactions of a large population of heterogeneous individuals. Each individual acts purposefully, but she knows anything about the levels of prices and quantities which clear markets in the aggregate. iii) In the hope of being allowed to purport scientific claims, BAM relies on the assumption that individual purposeful behaviours aggregates into regularities. Macro behaviour, however, can depart radically from what the individual units are trying to accomplish. It is in this sense that aggregate outcomes emerge from individual actions and interactions.

How ideas in complexity can be used to develop more effective public policy Complexity science—made possible by modern analytical and computational advances—is changing the way we think about social systems and social theory. Unfortunately, economists' policy models have not kept up and are stuck in either a market fundamentalist or government control narrative. While these standard narratives are useful in some cases, they are damaging in others, directing thinking away from creative, innovative policy solutions. Complexity and the Art of Public Policy outlines a new, more flexible policy narrative, which envisions society as a complex evolving system that is uncontrollable but can be influenced. David Colander and Roland Kupers describe how economists and society became locked into the current policy framework, and lay out fresh alternatives for framing policy questions. Offering original solutions to stubborn problems, the complexity narrative builds on broader philosophical traditions, such as those in the work of John Stuart Mill, to suggest initiatives that the authors call "activist laissez-faire" policies. Colander and Kupers develop innovative bottom-up solutions that, through new institutional structures such as for-benefit corporations, channel individuals’ social instincts into solving societal problems, making profits a tool for change rather than a goal. They argue that a central role for government in this complexity framework is to foster an ecostructure within which diverse forms of social entrepreneurship can emerge and blossom.

This groundbreaking new core textbook encourages students to take a more critical approach to the prevalent assumptions around the subject of macroeconomics, by comparing and contrasting heterodox and orthodox approaches to theory and policy. The first such textbook to develop a heterodox model from the ground up, it is based on the principles of Modern Monetary Theory (MMT) as derived from the theories of Keynes, Kalecki, Veblen, Marx, and Minsky, amongst others. The internationally-respected author team offer appropriate fiscal and monetary policy recommendations, explaining how the poor economic performance of most of the wealthy capitalist countries over recent decades could have been avoided, and delivering a well-reasoned practical and philosophical argument for the heterodox MMT approach being advocated. The book is suitable for both introductory and intermediate courses, offering a thorough overview of the basics and valuable historical context, while covering everything needed for more advanced courses. Issues are explained conceptually, with the more technical, mathematical material in chapter appendices, offering greater flexibility of use.

"The last decade has seen a lively debate in macroeconomics, with an increasing criticism on the model that seemed to be dominant in literature since the end of the 1990's, the Dynamic Stochastic General Equilibrium (DSGE, hereafter) and, consequently, the birth of some new theoretical approaches and methodologies"--

This book offers a practical guide to Agent Based economic modeling, adopting a “learning by doing” approach to help the reader master the fundamental tools needed to create and analyze Agent Based models. After providing them with a basic “toolkit” for Agent Based modeling, it present and discusses didactic models of real financial and economic systems in detail. While stressing the main features and advantages of the bottom-up perspective inherent to this approach, the book also highlights the logic and practical steps that characterize the model building procedure. A detailed description of the underlying codes, developed using R and C, is also provided. In addition, each didactic model is accompanied by exercises and applications designed to promote active learning on the part of the reader. Following the same approach, the book also presents several complementary tools required for the analysis and validation of the models, such as sensitivity experiments, calibration exercises, economic network and statistical distributions analysis. By the end of the book, the reader will have gained a deeper understanding of the Agent Based methodology and be prepared to use the fundamental techniques required to start developing their own economic models. Accordingly, “Economics with Heterogeneous Interacting Agents” will be of particular interest to graduate and postgraduate students, as well as to academic institutions and lecturers interested in including an overview of the AB approach to economic modeling in their courses.

Snowdon and Vane s book is extremely welcome. Indeed the authors examine, compare, and evaluate the evolution of the major rival stories comprising contemporary macroeconomic thought, but they also trace the development and interaction of key events and ideas as they occurred in the last century. Interviews with leading economists, one or two at the end of each chapter, also greatly help to shed light on this complexity. . . In sum, this is book which is very difficult to put down. Alessio Moneta, Journal of the History of Economic Thought It is not difficult to understand why this volume commands high praise from macroeconomic theorists, practitioners and teachers. It contains many interesting features that make it an excellent companion for both students and teachers of tertiary level macroeconomics. . . The authors present the material in a way that conveys to readers that macroeconomics is a living science , continually developing and still open to debate, controversy and competing policy prescriptions. In this respect it is a book that ought to be required reading for all teachers of the subject. It is also a valuable source of background reading for professional economists involved with economic policy making. Economic Outlook and Business Review . . . a wonderful history of macroeconomic thought from Keynes to the present, with an outstanding bibliography. It should be useful to undergraduates and graduate students as well as professional economists. Highly recommended. Steven Pressman, Choice Brian Snowdon and Howard Vane are well-known for their astute understanding of the main macroeconomic schools of thought and their skilled use of interviews with major figures. Here, they deploy a depth of scholarship in explaining the different schools and their key points of departure from one another. This book will be particularly useful to students looking for a clear, non-technical explanation of the main approaches to macroeconomics. Patrick Minford, Cardiff University, UK There are two steps to learning macroeconomics. First, to see it as it is today. Second, to understand how it got there: to understand the right and the wrong turns, the hypotheses that proved false, the insights that proved true, and the interaction of events and ideas. Only then, does one truly understand macroeconomics. This book is about step two. It does a marvellous job of it. The presentation is transparent, the interviews fascinating. You will enjoy, and you will learn. Olivier Blanchard, Massachusetts Institute of Technology, US In 40 years of teaching macroeconomics, there has been just one textbook that I have assigned year after year after year, namely, A Modern Guide to Macroeconomics by Snowdon, Vane and Wynarczyk. That altogether admirable book made clear to students what were, and are, the main intellectual issues in macroeconomics and did so with just enough formal modeling to avoid distortion by over-simplification. That book is now ten years old and the debate in macro has moved on. So there is good reason to welcome Snowdon and Vane back with this superb updated version. Axel Leijonhufvud, University of Trento, Italy This outstanding book avoids the narrow scope of most textbooks and provides an excellent guide to an unusually broad range of ideas. Thomas Mayer, University of California, Davis, US More than a decade after the publication of the critically acclaimed A Modern Guide to Macroeconomics, Brian Snowdon and Howard Vane have produced a worthy successor in the form of Modern Macroeconomics. Thoroughly extended, revised and updated, it will become the indispensable text for students and teachers of macroeconomics in the new millennium. The authors skilfully trace the origins, development and current state of modern macroeconomics from an historical perspective. They do so by thoroughly appraising the central tenets underlying the main competing schools of macroeconomic thought as well as their diverse policy imp
