This collection brings together important contributions by leading econometricians on (i) parametric approaches to qualitative and sample selection models, (ii) nonparametric and semi-parametric approaches to qualitative and sample selection models, and (iii) nonlinear estimation of cross-sectional and time series models. The advances achieved here can have important bearing on the choice of methods and analytical techniques in applied research.

Commerce, Complexity, and Evolution is a significant contribution to the paradigm - straddling economics, finance, marketing, and management - which acknowledges that commercial systems are evolutionary, and must therefore be analysed using evolutionary tools. Evolutionary systems display complicated behaviours which are to a significant degree generated endogenously, rather than being solely the product of exogenous shocks, hence the conjunction of complexity with evolution. This volume considers a wide range of systems, from the entire economy at one extreme to the behaviour of single markets at the other. The papers are united by methodologies which at their core are evolutionary, though the techniques cover a wide range, from philosophical discourse to differential equations, genetic algorithms, multi-agent simulations and cellular automata. Issues considered include the dynamics of debt-deflation, stock management in a complex environment, interactions between consumers and its effect upon market behaviour, and nonlinear methods to profit from financial market volatility.

New Approaches to Monetary Economics brings together presentations of innovative research in the field of monetary economics. Much of this research develops and applies approaches to modelling financial intermediation, aggregate fluctuations, monetary aggregation and transactions-motivated monetary equilibrium. The contents of this volume comprise the proceedings of the second in a conference series entitled International Symposia in Economic Theory and Econometrics. This conference was held in 1985 at the IC2 Institute at the University of Texas at Austin. The symposia in this series are sponsored by the IC2 Institute and the RGK Foundation. New Approaches to Monetary Economics, edited by Professors William A. Barnett and Kenneth J. Singleton, consists of five parts. Part I examines transactions-motivated monetary holding in general equilibrium; Part II, financial intermediation; Part III, monetary aggregation theory, Part IV, issues in aggregate fluctuation; and Part V, theoretical issues in the foundations of monetary economics and macroeconomics.

This book brings together presentations of some of the fundamental new research that has begun to appear in the areas of dynamic structural modeling, nonlinear structural modeling, time series modeling, nonparametric inference, and chaotic attractor inference. The contents of this volume comprise the proceedings of the third of a conference series entitled International Symposia in Economic Theory and Econometrics. This conference was held at the IC;s2 (Innovation, Creativity and Capital) Institute at the University of Texas at Austin on May 22–23, l986.
