The last fifteen or twenty years have been marked by fundamental advances in the sources of complex behavior in micro- and macro-economics, in the practical and methodological implications of such behavior, and in the methods and tools appropriate to cope with them. Much of these developments have been driven by the recognition and acceptance by economists of approaches initiated in other fields - such as non-linear dynamics, statistical physics, network theory, biology, computer science, and the use of computational methods as problem-solving tools - giving rise to important and innovative...

The series "International Symposia in Economic Theory and Econometrics" publishes quality proceedings of conferences and symposia. Since all articles published in these volumes are refereed relative to the standards of the best journals, not all papers presented at the symposia are published in these proceedings volumes. Occasionally these volumes include articles that were not presented at a symposium or conference, but are of high quality and are relevant to the focus of the volume. The topics chosen for these volumes are those of particular research importance at the time of the selection...

The nine papers in this volume are a diverse set of quality contributions to the field in economics that is called political economy. It is important to understand that social scientists hold different interpretations of the term political economy. Most mainstream economists expect a paper in the field to use the same models as are used in neoclassical economics, be it micro or macro. The field of political economy is seen by most economists to be exclusively the purview of their field. However, the political system of a country determines the nature of its economics system. The economy feeds...

The contents of this volume comprise the proceedings of the International Symposia in Economic Theory and Econometrics conference held in 1987 at the IC DEGREEST2 (Innovation, Creativity, and Capital) Institute at the University of Texas at Austin. The essays present fundamental new research on the analysis of complicated outcomes in relatively simple macroeconomic models. The book covers econometric modelling and time series analysis techniques in five parts. Part I focuses on sunspot equilibria, the study of uncertainty generated by nonstochastic economic models. Part II examines the more...

Presents some of the recent developments in nonlinear economic dynamics along with related research from associated fields, including mathematics, statistics, biology, and physics. Specific areas covered in the text include instability in economic theory, nonlinearity in financial markets, tests for nonlinearity and chaos, frequency domain methods, nonlinear business cycles, and nonlinear prediction and forecasting. This volume comprises the tenth in the International Symposia in Economic Theory and Econometrics series under the general editorship of William Barnett. This proceedings volume...

Nonlinear Econometric Modeling in Time Series Analysis presents recent developments in this important area of research. This is the first volume to focus on the more recent literature on nonlinear time series. Specific topics covered with respect to nonlinearity include cointegration tests, risk-related asymmetries, structural breaks and outliers, Bayesian analysis with a threshold, consistency and asymptotic normality, asymptotic inference, and error-correction models.

Commerce, Complexity, and Evolution is a significant contribution to the new paradigm straddling economics, finance, marketing, and management, which acknowledges that commercial systems are evolutionary systems, and must therefore be analyzed using evolutionary tools. Evolutionary systems display complicated behaviors that are to a significant degree generated endogenously, rather than being solely the product of exogenous shocks, hence the conjunction of complexity with evolution. The papers in this volume consider a wide range of systems, from the entire economy at one extreme to the...

The issues associated with population ageing are already assuming prominence in most OECD countries. Many governments are extremely concerned about the likely impact of population ageing upon future government outlays and economic growth. In Australia, for example, there have already been two major government reports that have attempted to quantify the likely implications for government spending of population ageing. These reports have concluded that there will either have to be cuts in current government programs, increases in taxes or some combination of these. The ageing population will...

The contents of this volume comprise the proceedings of the conference, "Equilibrium theory and applications." Some of the recent developments in general equilibrium theory in the perspective of actual and potential applications are presented. The conference was organized in honor of Jacques Dreze on the occasion of his sixtieth birthday. Held at C.O.R.E., it was also the unanimous recognition, stressed by Gerard Debreu in his Address, of his role as "the architect and builder" of the Center for Operations Research and Econometrics. An introductory address by Gerard Debreu comprises Part 1 of...

This collection of papers delivered at the fifth international Symposium in Economic Theory and Econometrics in 1988 is devoted to recent advances in the estimation and testing of models that impose relatively weak restrictions on the stochastic behavior of data. Particularly in highly nonlinear models, empirical results are very sensitive to the choice of the parametric form of the distribution of the observable variables, and often nonparametric and semiparametric models are a preferable alternative. Methods and applications that do not require strong parametric assumptions for their...
