This clearly written volume provides an accessible examination of the nature of disequilibrium models. Srivastava and Rao contend that existing software packages can be easily used to implement some of the relatively simple methods. This study furnishes a substantial grounding in the economics and econometrics of the disequilibrium models by reviewing the Walrasian general equilibrium theory and by comparing the two genuine alternative frameworks for analyzing economic phenomena. Srivastava and Rao demonstrate that while both frameworks share a common set of basic assumptions about the behavior of the economic decision making units, they differ in their assumptions about the ability of the markets to attain equilibrium within a single trading period and whether trading can take place out of equilibrium.
The first two chapters provide background, divide the existing methods of… Read More

Recent advances in establishing the nature and scope of estimators in econometrics have shed more light on the importance of instrumental variables. In this book, the authors argue that such methods may be regarded as a strong organizing principle for a wide variety of estimation and hypothesis testing problems in econometrics and statistics. In support of this claim they present and develop the methodology of instrumental variables in its most general and explanatory form. They show, for instance, that techniques commonly used to handle simultaneity and related problems can be reduced to one of two generic variables of instrumental variables estimators, allowing them to explore further the conditions under which different proposed estimators are efficient.

2000 purple & gray hardcover in like new condition; slight wear to covers, no marks inside. US media mail for shipping. A pioneering look at the fundamental role of logic in optimization and constraint satisfactionWhile recent efforts to combine optimization and constraint satisfaction have received considerable attention, little has been said about using logic in optimization as the key to unifying the two fields. Logic-Based Methods for Optimization develops for the first time a comprehensive conceptual framework for integrating optimization and constraint satisfaction, then goes a step further and shows how extending logical inference to optimization allows for more powerful as well as flexible modeling and solution techniques. Designed to be easily accessible to industry professionals and academics in both operations research and artificial intelligence, the book provides a wealth of examples as well as elegant techniques and modeling frameworks ready for implementation. Timely, original, and… Read More

1974 blue hardcover in very good+ condition, some wear to covers, stamp on 1st page, no marks inside. US media mail for shipping. To tailor time series models to a particular physical problem and to follow the working of various techniques for processing and analyzing data, one must understand the basic theory of spectral (frequency domain) analysis of time series. This classic book provides an introduction to the techniques and theories of spectral analysis of time series. In a discursive style, and with minimal dependence on mathematics, the book presents the geometric structure of spectral analysis. This approach makes possible useful, intuitive interpretations of important time series parameters and provides a unified framework for an otherwise scattered collection of seemingly isolated results.The books strength lies in its applicability to the needs of readers from many disciplines with varying backgrounds in mathematics. It provides a solid foundation in spectral analysis for fields that… Read More
