Available in PDF, EPUB and Kindle. Book excerpt: The following work identifies a new source of quantifiable risk in financial applications. Traditional economic and financial theories tend to ignore the limits on information communication and computation with notable exceptions such as Sims(2010). This is in spite of the fact that the science of such limits is well understood. Information and information processing have been treated qualitatively as either perfect or imperfect with little effort to incorporate them in a precise and practical way. Over the years this omission has become even more egregious given the data driven and digitally dominated world in which the vast majority of financial activity takes place. In addition to building new theoretical foundations, practical applications of the theory to problems in finance are suggested in this work. In the first chapter the concept of the economy's information processing efficiency is intuitively introduced. The theory is expanded in Chapter 2 which explores the relationships between the arrival and processing rates of information at financial markets. This analysis is used to demonstrate mathematically how financial flash crashes can occur without large changes in the information arrival process. In chapter 3 the economy's information processing efficiency (R/C) is theoretically and empirically derived from a reformulation of the yield curve. The theory is also intuitively extended to explain in a new way the large-scale declines in the markets typically seen at the end of business cycles. The full evolution of the business cycle is described from the perspective of this new theory and measure in Chapter 4. The new measure is used in Chapter 5 to improve portfolio management over business cycles in conjunction with more traditional methods. The fractal structure of R/C is explored mathematically and explained metaphorically in Chapter 6. In the last chapter the theory elucidates a previously unknown and important connection between the disparate branches of finance and opens many new vistas for future research and real-world applications.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an epistemic framework for dealing with information-knowledge and certainty-uncertainty problems within the space of quality-quantity dualities. It bridges between theoretical concepts of entropy and entropy measurements, proposing the concept and measurement of fuzzy-stochastic entropy that is applicable to all areas of knowing under human cognitive limitations over the epistemological space. The book builds on two previous monographs by the same author concerning theories of info-statics and info-dynamics, to deal with identification and transformation problems respectively. The theoretical framework is developed by using the toolboxes such as those of the principle of opposites, systems of actual-potential polarities and negative-positive dualities, under different cost-benefit time-structures. The category theory and the fuzzy paradigm of thought, under methodological constructionism-reductionism duality, are used in the fuzzy-stochastic and cost-benefit spaces to point to directions of global application in knowing, knowledge and decision-choice actions. Thus, the book is concerned with a general theory of entropy, showing how the fuzzy paradigm of thought is developed to deal with the problems of qualitative-quantitative uncertainties over the fuzzy-stochastic space, which will be applicable to conditions of soft-hard data, fact, evidence and knowledge over the spaces of problem-solution dualities, decision-choice actions in sciences, non-sciences, engineering and planning sciences to abstract acceptable information-knowledge elements.

Available in PDF, EPUB and Kindle. Book excerpt: All economic and financial activity involves the communication of information across space and time. Additionally, communicated and processed information is the only universal fundamental input to all economic and financial production and exchange. Well established laws from physics and information theory determine the evolution of entropy, the limits on information communication and processing, and the growth of additional uncertainty or entropy as those limits are exceeded. Apparent anomalies such as non-constant implied volatilities across strikes and terms to expiration, and the complete structure of the yield curve arise intuitively when information theory is applied to economics and finance. In fact the current methods used by practitioners to model the volatility surface and the yield curve can be viewed as approximations of the richer structures revealed by information theory.

Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes environmental protection and resource use in a comprehensive framework where not only economic but also natural scientific aspects are taken into consideration. The special features of the book are (i) that the authors utilize a natural scientific variable, entropy, to characterize the economic system and the environment, (ii) that environmental protection and resource use are analyzed in combination, and (iii) that a replacement of techniques over time is analyzed. The authors investigate the use of the environment both as a supplier of resources and as a recipient of pollutants with the help of thermodynamic relationships. The book therefore provides a new set of tools for environmentalists and economists.

Book excerpt: This book describes a system of mathematical models and methods that can be used to analyze real economic and managerial decisions and to improve their effectiveness. Application areas include: management of development and operation budgets, assessment and management of economic systems using an energy entropy approach, equation of exchange rates and forecasting foreign exchange operations, evaluation of innovative projects, monitoring of governmental programs, risk management of investment processes, decisions on the allocation of resources, and identification of competitive industrial clusters. The proposed methods and models were tested on the example of Kazakhstan’s economy, but the generated solutions will be useful for applications at other levels and in other countries. Regarding your book "Mathematical Methods and Models in Economics", I am impressed because now it is time when "econometrics" is becoming more appreciated by economists and by schools that are the hosts or employers of modern economists. ... Your presented results really impressed me. John F. Nash, Jr., Princeton University, Nobel Memorial Prize in Economic Sciences The book is within my scope of interest because of its novelty and practicality. First, there is a need for realistic modeling of complex systems, both natural and artificial that conclude computer and economic systems. There has been an ongoing effort in developing models dealing with complexity and incomplete knowledge. Consequently, it is clear to recognize the contribution of Mutanov to encapsulate economic modeling with emphasis on budgeting and innovation. Secondly, the method proposed by Mutanov has been verified by applying to the case of the Republic of Kazakhstan, with her vibrant emerging economy. Thirdly, Chapter 5 of the book is of particular interest for the computer technology community because it deals with innovation. In summary, the book of Mutanov should become one of the outstanding recognized pragmatic guides for dealing with innovative systems. Andrzej Rucinski, University of New Hampshire This book is unique in its theoretical findings and practical applicability. The book is an illuminating study based on an applied mathematical model which uses methods such as linear programming and input-output analysis. Moreover, this work demonstrates the author’s great insight and academic brilliance in the fields of finance, technological innovations and marketing vis-à-vis the market economy. From both theoretical and practical standpoint, this work is indeed a great achievement. Yeon Cheon Oh, President of Seoul National University

This book was released on 2023-06-09 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuzzy sets have experienced multiple expansions since their conception to enhance their capacity to convey complex information. Intuitionistic fuzzy sets, image fuzzy sets, q-rung orthopair fuzzy sets, and neutrosophic sets are a few of these extensions. Researchers and academics have acquired a lot of information about their theories and methods for making decisions. However, only a small number of research findings discuss how neutrosophic sets theory and their extensions (NSTEs) are used in education. The Handbook of Research on the Applications of Neutrosophic Sets Theory and Their Extensions in Education implements fresh scientific approaches to enhance the quality of decisions under neutrosophic environments, particularly within education. Covering key topics such as data modeling, educational technologies, decision making, and learning management systems, this major reference work is ideal for instructional designers, researchers, academicians, scholars, practitioners, instructors, and students.

Available in PDF, EPUB and Kindle. Book excerpt: ÔThis book is an ambitious intellectual enterprise to build a naturalistic foundation for economics, with amazingly vast knowledge of physical, biological, social sciences and philosophy. Readers will discover that approaches and insights emergent in institutional studies, (social)-neuroscience, network theory, ecological economics, bio-culture dualistic evolution, etc. are persuasively placed in a grand unified frame. It is written in a good Hayekian tradition. I recommend this book particularly to young readers who aspire to go beyond a narrowly specified discipline in the age of expanding communicability of knowledge and ideas.Õ Ð Masahiko Aoki, Stanford University, US ÔCarsten Herrmann-PillathÕs new book is an in-depth application of natural philosophy to economics that draws up an entirely new framework for economic analysis. It offers path-breaking insights on the interactions between human economic activity and nature and outlines a convincing solution to the long-standing reductionism controversy. A must-read for everyone interested in the philosophical underpinnings of economics as a science.Õ Ð Ulrich Witt, Max Planck Institute of Economics, Jena, Germany ÔÒBig pictureÓ philosophy of economics drifted into a dull cul-de-sac as it became obsessively focused on falsifiability and rationality. In this book Carsten Herrmann-Pilath pushes the field back onto the open highway by locating economics in the larger frameworks of metaphysics, evolutionary dynamics and information theory. This is large-scale, ambitious synthesis of ideas of the kind we expect from time to time to see devoted to physics and biology. Why should economics merit anything less? But of course this kind of intellectual tapestry must await the appearance of an unusually devoted scholar with special patience and eccentric independence from the pressure for quick returns that characterizes academic life. In the person of Hermann-Pilath this scholar has appeared. No one who wants to examine economics whole and in its richest context should miss his virtuoso performance in this book.Õ Ð Don Ross, University of Cape Town, South Africa and Georgia State University, US ÔHerrmann-PillathÕs work attempts to bring to bear upon the discipline of economics perspectives from other discourses which have been burgeoning recently Ð namely, thermodynamics, evolutionary biology, and semiotics, aiming at a consilience contextualized by economic activity and problems. This marks the work as a contemporary example of natural philosophy, which is now at the doorstep of a revival. The overall perspective is that human economic activity is an aspect of the ecology of the earthÕs surface, viewing it as an evolving physical system mediated through distributed mentality as expressed in technology evolution. Knowledge is taken to be ÔphysicalÕ with a performative function, as in PeirceÕs pragmaticism. Thus, the social meanings of expectations, prices, and credit are found to be rooted in energy flows. The work draws its foundation from Hegel and C.S. Peirce and its immediate guidance from Hayek, Veblen and Georescu-Roegen. The author generates an energetic theory of economic growth, guided by OdumÕs maximum power principle. Economic discourse itself is reworked in the final chapter, in light of the examinations of the previous chapters, naturalizing economics within an extremely powerful contemporary framework.Õ Ð Stanley N. Salthe, Binghamton University, US ÔAn Oscar-winning performance in the Òtheatre of consilience.Ó ItÕs hard to know which to praise first: Carsten Herrmann-PillathÕs humility or his ambition. He says his book Òis not a great intellectual featÓ because he pursues the Òhumble taskÓ of putting together Òthe ideas of others.Ó When he finally gets to economics he tries to Òbe as simple as possibleÓ and to conceive of economics in terms of the basics, at Òundergraduate level, so to say.Ó On the other hand, the scale of his ambition is to rethink the foundations of economics from first principles, while, at the same time, holding a running dialogue between contemporary sciences and classic philosophy. HeÕs much too modest, of course, because Foundations is a major achievement, but his modesty points to what makes it such a powerful treatise: the book is not about his preferences or prejudices; it is a Òscientific approach that aims at establishing truthful propositions about reality.Ó That is much harder to achieve than grand theories or Òcomplicated mathematics,Ó because it amounts to a new modern synthesis of the field Ð an achievement on a par with Julian HuxleyÕs, whose own modern synthesis of evolutionary theories in the 1940s allowed for the explosive growth of the biosciences over the next decades. The structure of the book is simple enough, providing a framework for the Ònaturalistic turnÓ in economics. Starting from material existence, causation and evolution, Herrmann-Pillath takes us through four fundamental concepts Ð individuals, networks, institutions and technology Ð before coming finally to the Òrealm of economics proper,Ó i.e. markets. However, Herrmann-Pillath believes that the Òfoundations of economics cannot be found within economicsÓ but only in dialogue with other sciences, or what he calls the Òtheatre of consilience.Ó ItÕs a theatre in which various characters come and go, where dialogue ebbs and flows, conflicts arise and are resolved, and where individual actions can be seen as concepts as, leading to higher levels of meaning as the plot unfolds. The magic of theatre, of course, is that the point of intelligibility, where the characters, actions and narrative resolve into meaningfulness, is projected out of the drama itself, into the spectator. ThatÕs you, dear reader. So it is with economics as a discipline. Economics is a player in a much larger performance about what constitutes knowledge, and how we know that. It is also a player in the economy it seeks to explain. To understand why money, firms, growth, prices, markets and other staples of economic thought emerge and function the way they do, it is necessary situate the analysis beyond economics (and the economy), and to engage with developments across the human, evolutionary and complexity sciences. This is what Herrmann-Pillath does, analyzing a breathtaking range of illuminating and sometimes challenging work along the way. We are treated to new ideas about the externalized brain, the evolution of knowledge in the Earth System (i.e. not just among humans), the role of signs and performativity in these processes, as well as that of Òenergetic transformations.Ó But Herrmann-Pillath is not satisfied with the ÒmodestÓ task of bringing the best of modern scientific thought to bear on economic concepts and performances; he really does harbor a deeper purpose. The clue is in his apparently quixotic desire to hang on to philosophical insights associated with pre-evolutionary thinkers like Aristotle and Hegel, and his apparently eccentric desire to place the semiotic philosophy of C.S. Pierce at center stage. But the patient observer will see that he is not seeking to change the facts by imposing idealist notions on them after the event. Instead, he is arguing for a change in the way we perform ourselves in the face of these facts. He is looking for a modern-day equivalent of Confucius or Socrates: one who can imagine values and beliefs that Òdefine the human species in a new way.Ó For those who have eyes to see, as the drama unfolds, it may be that we have found such a figure in Carsten Herrmann-Pillath himself, modesty, ambition and all. This is ÒCultural ScienceÓ as it should be done.Õ Ð John Hartley, Curtin University, Australia and Cardiff University, UK
