Takuma Yasui
was a Japanese economist known for his contributions to mathematical economics. In particular, he is recognized as one of the first economists to utilize Lyapunov stability theory for analyzing the stability of economic equilibria. In 1970, he served as president of the Japanese Economic Association The Japanese Economic Association (JEA) is the professional body of Japanese economists. The Japanese Economic Association is the largest, with more than 3,000 members, among academic economic associations in Japan. The Association is also one of ....

Economist
An economist is a professional and practitioner in the social sciences, social science discipline of economics. The individual may also study, develop, and apply theories and concepts from economics and write about economic policy. Within this field there are many sub-fields, ranging from the broad philosophy, philosophical theory, theories to the focused study of minutiae within specific Market (economics), markets, macroeconomics, macroeconomic analysis, microeconomics, microeconomic analysis or financial statement analysis, involving analytical methods and tools such as econometrics, statistics, Computational economics, economics computational models, financial economics, mathematical finance and mathematical economics. Professions Economists work in many fields including academia, government and in the private sector, where they may also "study data and statistics in order to spot trends in economic activity, economic confidence levels, and consumer attitudes. They assess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematical Economics
Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. Often, these applied methods are beyond simple geometry, and may include differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, or other computational methods. Proponents of this approach claim that it allows the formulation of theoretical relationships with rigor, generality, and simplicity. Mathematics allows economists to form meaningful, testable propositions about wide-ranging and complex subjects which could less easily be expressed informally. Further, the language of mathematics allows economists to make specific, positive claims about controversial or contentious subjects that would be impossible without mathematics. Much of economic theory is currently presented in terms of mathematical economic models, a set of stylized and simplified mathematical relationships asserted to clarify ass ...

Lyapunov Stability
Various types of stability may be discussed for the solutions of differential equations or difference equations describing dynamical systems. The most important type is that concerning the stability of solutions near to a point of equilibrium. This may be discussed by the theory of Aleksandr Lyapunov. In simple terms, if the solutions that start out near an equilibrium point x_e stay near x_e forever, then x_e is Lyapunov stable. More strongly, if x_e is Lyapunov stable and all solutions that start out near x_e converge to x_e, then x_e is asymptotically stable. The notion of exponential stability guarantees a minimal rate of decay, i.e., an estimate of how quickly the solutions converge. The idea of Lyapunov stability can be extended to infinite-dimensional manifolds, where it is known as structural stability, which concerns the behavior of different but "nearby" solutions to differential equations. Input-to-state stability (ISS) applies Lyapunov notions to systems with inputs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Equilibrium
In economics, economic equilibrium is a situation in which economic forces such as supply and demand are balanced and in the absence of external influences the ( equilibrium) values of economic variables will not change. For example, in the standard text perfect competition, equilibrium occurs at the point at which quantity demanded and quantity supplied are equal. Market equilibrium in this case is a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers. This price is often called the competitive price or market clearing price and will tend not to change unless demand or supply changes, and quantity is called the "competitive quantity" or market clearing quantity. But the concept of ''equilibrium'' in economics also applies to imperfectly competitive markets, where it takes the form of a Nash equilibrium. Understanding economic equilibriu ...

Japanese Economic Association
The Japanese Economic Association (JEA) is the professional body of Japanese economists. The Japanese Economic Association is the largest, with more than 3,000 members, among academic economic associations in Japan. The Association is also one of the oldest, founded in 1934. The Association was reorganized as the Theoretical Economic Association and the Japanese Econometric Association. These two Associations were reunited as the Japan Association of Economics and Econometrics in 1968. The original name of the Association was restored in 1997. Its current president is Hideshi Itoh. It publishes the '' Japanese Economic Review''. The Association created an official prize, the Nakahara Prize, for the first time in 1995, named after its sponsor Nobuyuki Nakahara. The aim of the prize is honoring and encouraging young (under 45 years) economists to publish internationally-recognised researches. Founding members Founding members of JEA included Yasuma Takada, Ichiro Nakayama, Shin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
