Mathematical Models in Economics is a component of Encyclopedia of Mathematical Sciences in which is part of the global Encyclopedia of Life Support Systems (EOLSS), an integrated compendium of twenty one Encyclopedias. This theme is organized into several different topics and introduces the applications of mathematics to economics. Mathematical economics has experienced rapid growth, generating many new academic fields associated with the development of mathematical theory and computer. Mathematics is the backbone of modern economics. It plays a basic role in creating ideas, constructing new theories, and empirically testing ideas and theories. Mathematics is now an integral part of economics. The main advances in modern economics are characterized by applying mathematics to various economic problems. Many of today's profound insights into economic problems could hardly be obtained without the help of mathematics. The concepts of equilibrium versus non-equilibrium, stability versus instability, and steady states versus chaos in the contemporary literature are difficult to explain without mathematics. The theme discusses on modern versions of some classical economic theories, taking account of balancing between significance of economic issues and mathematical techniques. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

The problems of interrelation between human economics and natural environment include scientific, technical, economic, demographic, social, political and other aspects that are studied by scientists of many specialities. One of the important aspects in scientific study of environmental and ecological problems is the development of mathematical and computer tools for rational management of economics and environment. This book introduces a wide range of mathematical models in economics, ecology and environmental sciences to a general mathematical audience with no in-depth experience in this specific area. Areas covered are: controlled economic growth and technological development, world dynamics, environmental impact, resource extraction, air and water pollution propagation, ecological population dynamics and exploitation. A variety of known models are considered, from classical ones (Cobb Douglass production function, Leontief input-output analysis, Solow models of economic dynamics, Verhulst-Pearl and Lotka-Volterra models of population dynamics, and others) to the models of world dynamics and the models of water contamination propagation used after Chemobyl nuclear catastrophe. Special attention is given to modelling of hierarchical regional economic-ecological interaction and technological change in the context of environmental impact.

This second edition, now featuring new material, focuses on the valuation principles that are common to most derivative securities. A wide range of financial derivatives commonly traded in the equity and fixed income markets are analysed, emphasising aspects of pricing, hedging and practical usage. This second edition features additional emphasis on the discussion of Ito calculus and Girsanovs Theorem, and the risk-neutral measure and equivalent martingale pricing approach. A new chapter on credit risk models and pricing of credit derivatives has been added. Up-to-date research results are provided by many useful exercises.

This is Volume 2 of 2, covering Chapters 24 - 34 and the appendices. See www.textbookequity.org/principles-of-economics Excerpt: Principles of Economics is designed for a two-semester principles of economics sequence. The text has been developed to meet the scope and sequence of most introductory courses. At the same time, the book includes a number of innovative features designed to enhance student learning. Instructors can also customize the book, adapting it to the approach that works best in their classroom. The pedagogical choices, chapter arrangements, and learning objective fulfillment were developed and vetted with feedback from educators dedicated to the project. They thoroughly read the material and offered critical and detailed commentary. The outcome is a balanced approach to micro and macro economics, to both Keynesian and classical views, and to the theory and application of economics concepts. Current events are treated in a politically-balanced way as well.

This monograph is devoted to an interesting class of dynamical systems arising in economic dynamics. Dynamical systems theory has been a rapidly growing area of research which has various applications to physics, engineering, biology and economics. In this theory one of the goals is to study the asymptotic behaviour of the trajectories of a dynamical system. A discrete-time dynamical system is described by a space of states and a sequence of transition operators which can be set-valued. Two types of dynamical systems are considered in the literature: autonomous, with a single transition operator which does not depend on time, and non-autonomous, with transition operators depending on time. In the monograph the authors discuss a number of results concerning this model which were obtained by the author in the last fifteen years. They study the existence of trajectories on which consumption tends to infinity, discuss the existence and structure of optimal solutions and analyse allocations of labour resources. The authors introduce an optimality criterion for the trajectories of the model, establish the existence of optimal trajectories and examine their structure. They consider a multi-product extension of the Makarov model and its extension with expenditures required for reallocation of labour resources.

A lot of economic problems can formulated as constrained optimizations and equilibration of their solutions. Various mathematical theories have been supplying economists with indispensable machineries for these problems arising in economic theory. Conversely, mathematicians have been stimulated by various mathematical difficulties raised by economic theories. The series is designed to bring together those mathematicians who were seriously interested in getting new challenging stimuli from economic theories with those economists who are seeking for effective mathematical tools for their researchers.

This is the first part of a two-volume set on Concordian economics, a new paradigm whose core completes the Aristotelian-Aquinian project of economic justice. The book delves into the history of economics and presents Concordian economics as a response to the concerns and shortcomings of mainstream economics. Demand-side economics is represented in the process of consumption—the expenditure of monetary wealth to acquire real wealth and financial wealth of a different nature. In contrast, supply-side economics is represented in the production process, the process of producing real wealth, e.g. tables, chairs and foodstuffs. Institutionalists will also welcome this book because it ties the world of real wealth to that of monetary wealth through the process of distributing the value of ownership of both monetary and real wealth as they are created. The book begins with an introduction to Concordian economics, followed by a discussion of how to restore relevance to the field of economic studies. It also presents a revision of the Keynesian model designed to gradually address the major social, economic, and political causes of discord. Moreover, the author warns against the separation of economics from the world of physical things as well as the world of legal and moral issues. Following a discussion on the measurement of real wealth, econometrics is introduced in accordance with the categories of Concordian economics. Lastly, the book develops a theory of economic justice by defining a set of economic rights and responsibilities that guide economic behavior and policy. This book appeals to scholars and students of economics and related fields, as well as anyone interested in reintegrating economics into the social context.

Economic Theory and Mathematical Economics: Mathematics for Stability and Optimization of Economic Systems provides information pertinent to the stability aspects and optimization methods relevant to various economic systems. This book presents relevant mathematical theorems sufficient to develop important economic systems, including Leontief input–output systems, Keynesian dynamic models, the Ramsey optimal accumulation systems, and von Neumann expanding economic systems. Organized into two parts encompassing nine chapters, this book begins with an overview of useful theorems on matrices, eigenvalue problems, and matrices with dominant diagonals and P-matrices. This text then explores the linear transformations on vector spaces. Other chapters consider the Hawkins–Simon theorem concerning non-negative linear systems. This book discusses as well the dual linear relations and optimization methods applicable to inequality economic systems. The final chapter deals with powerful optimal control method for dynamical systems. This book is a valuable resource for mathematicians, economists, research workers, and graduate students.
