Bücher der Reihe Evolutionary Economics and Social Complexity Science

This book both summarizes the basic theory of evolutionary games and explains their developing applications, giving special attention to the 2-player, 2-strategy game. Applying the framework of evolutionary games to realistic traffic flows, the book reveals that social dilemma structures lie behind traffic flow.

This book covers various data scientific approaches to analyze the issue of grid integration of renewable energy for which the grid flexibility is the key to cope with its intermittency. It provides readers with the scope to view renewable energy integration as establishing a distributed energy network instead of the traditional centralized energy system. Specifically, quantitative valuation system-wise of the levelized cost of energy, which includes both initial cost and various operational costs, enables readers to optimize energy systems in order to minimize economic cost and environmental impact. It is noted, however, that the high cost of integrating renewable energy on a large scale might slow economic growth considerably. Topics addressed in the book also include statistical comparative study of the relationship between energy and economic growth, a graphical model of determinant factors for foreign direct investment in renewable energy, the coupled oscillator model and unitcommitment model to capture intermittency of renewable energy, and the network model of evolving micro-grids. The book explains desired innovation to reduce the integration cost significantly using innovative technologies such as energy storage with hydrogen production and vehicle-to-grid technology. Illustrated by careful analysis of selected examples of renewable integration using different types of grid flexibility, this volume is indispensable to readers who make policy recommendations to establish the distributed energy network integrated with large-scale renewable energy by disentangling the nexus of energy, environment, and economic growth.

An innovative feature of this book is its econocentric structure, focusing on digital designs. From the outset, econocentrism is assumed to be a core engine of capitalism, like money. The new coronavirus pandemic has changed lifestyles worldwide, which are unlikely ever to return in their original form. This great transformation will change the nature of the socio-economic system itself and will be centered on digital designs. At present, money already is beginning to undergo a major revolution in that sense. Many books dealing with digital designs and innovations have been published, but few if any of them focus on monetary and analytical methods in the way that this present volume does.The book then contains 6 parts: Evolution of money and thinking complexities in the AI era; Goods market and the future of labor market; Computational social approaches to social dilemmas, smart city, cryptocurrencies; Artificial market experiments; The randomness and high frequencies in financial data; Other trading strategy issues and the effects of AI usage. These issues may be indispensable subjects in our age. Study these subject, and have a step forward to the future society!

This is the first book that systematically considers the academic achievements of Japanese institutionalist post-Keynesian economists in the postwar period and argues that we can learn much from their intellectual heritage. Those Japanese economists include the world-renowned figures, Shigeto Tsuru and Hirofumi Uzawa, whose inheritance came from Keynes, Marx, and institutionalism. In the era of globalization after the 1990s, economic inequality and social divide have intensified all over the world. In this situation, the academic achievements of those economists in postwar Japan should be reconsidered for the aim of establishing a new political economy. With this perspective, the book looks at what we can learn from Japanese institutionalist post-Keynesian economists In particular, the essence of research work that each of them developed is identified, focusing on the total image of the economy for contemporary capitalism. Those economists benefited from the diverse legacies of Keynes, Marx, Kalecki and institutionalist economists such as Veblen and Galbraith. When their research is examined systematically, Japanese institutionalist post-Keynesians are commonly characterized as those who developed their institutional analysis of contemporary capitalism with in-depth theoretical and empirical studies, with the aim of establishing their own political economy as the moral science of civil society. These important features provide us with insightful implications for institutional economics in the 21st century.

This book presents the novel approach of analyzing large-sized rectangular-shaped numerical data (so-called big data). The essence of this approach is to grasp the "meaning" of the data instantly, without getting into the details of individual data. Unlike conventional approaches of principal component analysis, randomness tests, and visualization methods, the authors' approach has the benefits of universality and simplicity of data analysis, regardless of data types, structures, or specific field of science. First, mathematical preparation is described. The RMT-PCA and the RMT-test utilize the cross-correlation matrix of time series, C = XXT, where X represents a rectangular matrix of N rows and L columns and XT represents the transverse matrix of X. Because C is symmetric, namely, C = CT, it can be converted to a diagonal matrix of eigenvalues by a similarity transformation SCS-1 = SCST using an orthogonal matrix S. When N is significantly large, the histogram of the eigenvalue distribution can be compared to the theoretical formula derived in the context of the random matrix theory (RMT, in abbreviation). Then the RMT-PCA applied to high-frequency stock prices in Japanese and American markets is dealt with. This approach proves its effectiveness in extracting "trendy" business sectors of the financial market over the prescribed time scale. In this case, X consists of N stock- prices of length L, and the correlation matrix C is an N by N square matrix, whose element at the i-th row and j-th column is the inner product of the price time series of the length L of the i-th stock and the j-th stock of the equal length L. Next, the RMT-test is applied to measure randomness of various random number generators, including algorithmically generated random numbers and physically generated random numbers. The book concludes by demonstrating two applications of the RMT-test: (1) a comparison of hash functions, and (2) stock prediction by means of randomness, including a new index of off-randomness related to market decline.

This is the first book to provide a systematic description of statistical properties of large-scale financial data. Specifically, the power-law and log-normal distributions observed at a given time and their changes using time-reversal symmetry, quasi-time-reversal symmetry, Gibrat's law, and the non-Gibrat's property observed in a short-term period are derived here. The statistical properties observed over a long-term period, such as power-law and exponential growth, are also derived. These subjects have not been thoroughly discussed in the field of economics in the past, and this book is a compilation of the author's series of studies by reconstructing the data analyses published in 15 academic journals with new data. This book provides readers with a theoretical and empirical understanding of how the statistical properties observed in firms' large-scale data are related along the time axis. It is possible to expand this discussion to understand theoretically and empirically how the statistical properties observed among differing large-scale financial data are related. This possibility provides readers with an approach to microfoundations, an important issue that has been studied in economics for many years.

This book presents the fundamentals of evolutionary game theory and applies them to the analysis of epidemics, which is of paramount importance in the aftermath of the worldwide COVID-19 pandemic. The primary objective of this monograph is to deliver a powerful tool to model and analyze the spread of an infectious disease during a pandemic as well as the human decision dynamics. The book employs a variant of the "e;vaccination game,"e; in which a mathematical epidemiological model dovetails with evolutionary game theory. From a social physics standpoint, this book introduces an extended concept of the vaccination game starting from the fundamental issues and touching on the newest practical applications.The book first outlines the fundamental basis of evolutionary game theory, in which a two-player and two-strategy game, the so-called 2 2 game, and a multi-player game are concisely introduced, and the important issue of how social dilemmas are quantified is highlighted. Subsequently, the book discusses various recent applications of the extended concept of the vaccination game so as to quantitatively evaluate provisions other than vaccination, including practical intermediate protective measures such as mask-wearing, efficiency of quarantine compared with that of isolation policies for suppressing epidemics, efficiency of preemptive versus late vaccination, and optimal subsidy policies for vaccination.

This book develops a unified treatment of the income distribution-capital-value problems with respect to actual economies, and then gradually turns to the issues of effective demand and capitalist accumulation fluctuations from both political economy and economic policy perspectives.

This is the first book that comprehensively analyses co-patenting in Japan and the U.S., which directly signifies collaborations between firms and inventors, using the methodology of network science.

This is the first book to provide a systematic description of statistical properties of large-scale financial data.

This book integrates the concept of design into the existing framework of industrial performance, international trade and comparative advantage in trade and industrial phenomena, which increasingly have been affected by design characteristics of tradable goods.

This book presents examples of and the latest simulation studies on artificial societies and populations, highlighting innovative implementations of various models of artificial societies and populations using a new, C++-related simulation tool.

There are few books that systematically discuss Keynes and Knight, although there are remarkable comparisons between Keynes's concept of probability and uncertainty and Knight's distinction between a measurable risk and a non-measurable uncertainty.

This book systematically provides a prospective integrated approach for complexity social science in its view of statistical physics and mathematics, with an impressive collection of the knowledge and expertise of leading researchers from all over the world.

This book examines corporate reform in Japan by focusing on corporate governance and the employment system. Chapter 1 discusses how Japanese corporate governance changed incrementally and cumulatively to rebuild management and restore corporate performance.

This book is devoted to analyzing contemporary capitalism both in Japan and in the world economy by using the theoretical framework of the French regulation theory and by revisiting the theory of civil society in postwar Japan.

and whether socially responsible investment can be a social institution for corporate governance.The book is also addressed to philosophers of social sciences interested in how experimental methods can contribute to developing cognition of human behaviors and be extended to social theories.

Modern Classical Economics and Reality

This book discerns and distinguishes essential features of basic economic theories developed in the 1930s to 1950s, and compares them with theories that have arisen in recent years. Covers the advent of socioeconophysics, and many other contemporary trends.

This book integrates three levels of political-economic analysis: first a comparative institutional analysis of the varieties of capitalism in both Europe and Asia, second a macroeconomic analysis of industrial structural change and economic dynamics of the national economies in Europe and Asia, and then an encompassing analysis of international production linkages and international financial instability which determine the long-term patterns of regional integration in Europe and Asia. The comparison of the European Union and ASEAN delivers some key conditions for a viable long-term regional economic integration to cope with contrasted capitalisms and growth regimes: either pragmatism in the choice of an exchange rate regime, or a form of fiscal federalism. The reader will also find a genuine analysis of the dynamism of the Chinese economy, a study on institutional changes and de-industrialization in Japan, and the increasing international production linkages among China, Japan, Korea, and ASEAN. It is shown how the enlargement of the European Union and the Euro triggered the diverging competitiveness and macroeconomic performances that led to the crisis of a six decades long economic and political process. This book is the result of long lasting Asian-European collaborative research. It is a milestone in the historical and comparative analysis along the régulation theory that aims at understanding the long-run transformations, renewed diversity and interdependence of capitalisms.

This book focuses on how important massive information is and how sensitive outcomes are to information.

He also believed that the reasonable value could be achieved by the evolution of institutions.There is no doubt that Commons's ideas proposed in Institutional Economics such as transactions and collective actions greatly inspired later economists;

This book takes up unique agent-based approaches to solving problems related to stock and their derivative markets. Toward this end, the authors have worked for more than 15 years on the development of an artificial market simulator called U-Mart for use as a research and educational tool. A noteworthy feature of the U-Mart simulator compared to other artificial market simulators is that U-Mart is an ultra-realistic artificial stock and their derivative market simulator. For example, it can simulate "arrowhead," a next-generation trading system used in the Tokyo Stock Exchange and other major markets, as it takes into consideration the institutional design of the entire market. Another interesting feature of the U-Mart simulator is that it permits both human and computer programs to participate simultaneously as traders in the artificial market. In this book, first the details of U-Mart are explained, enabling readers to install and run the simulator on their computers for research and educational purposes. The simulator thus can be used for gaming simulation of the artificial market and even for users as agents to implement their own trading strategies for agent-based simulation (ABS).The book also presents selected research cases using the U-Mart simulator. Here, topics include automated acquisition of trading strategy using artificial intelligence techniques, evaluation of a market maker system to treat thin markets such as those for small and regional businesses, systemic risk analysis of the financial market considering institutional design of the market, and analysis of how humans behave and learn in gaming simulation. New perspectives on artificial market research are provided, and the power, potential, and challenge of ABS are discussed. As explained in this important work, ABS is considered to be an effective tool as the third approach of social science, an alternative to traditional literary and mathematical approaches.

While employing a variety of approaches to address topics such as economic interdependence among democracies and authoritarian states, the development assistance regimes, internal conflicts in developing countries, and cyber security, the whole volume presents a clear overview of challenges and risks the world is facing.

This book presents new theory and empirical studies on the roles of cognitive workload and fatigue on repeated financial decisions.

Recent applications of evolutionary game theory in the merging fields of the mathematical and social sciences are brilliantly portrayed in this book, which highlights social physics and shows how the approach can help to quantitatively model complex human-environmental-social systems.First, readers are introduced to the fundamentals of evolutionary game theory. The two-player, two-strategy game, or the 2 × 2 game, is presented as an archetype to help understand the difficulty of cooperating for survival against defection in common social contexts. Subsequently, the book explains the theoretical background of the multi-player, two-strategy game, which may be more widely applicable than the 2 × 2 game for social dilemmas. The latest applications of 2 × 2 games are also discussed to explore how integrated reciprocity mechanisms can solve social dilemmas.In turn, the book describes two practical areas in which evolutionary game theory has been applied. The first concerns traffic flow analysis. In conventional interpretations, traffic flow can be understood by means of fluid dynamics, in which the flow of vehicles is evaluated as a continuum body. Such a simple idea, however, does not work well in reality, particularly if a driver's decision-making process is considered. Various dilemmas involve complex structures that depend primarily on traffic density, a revelation that should help establish a practical solution for reducing traffic congestion.Second, the book provides keen insights into how powerful evolutionary game theory can be in the context of epidemiology. Both approaches, quasi-analytical and multi-agent simulation, can clarify how an infectious disease such as seasonal influenza spreads across a complex social network, which is significantly affected by the public attitude toward vaccination. A methodology is proposed for the optimum design of a public vaccination policy incorporating subsidies to efficiently increase vaccination coverage while minimizing the social cost.
