Hirofumi Uzawa
was a Japanese economist. Biography Uzawa was born on July 21, 1928 in Yonago, Tottori to a farming family. He attended the Tokyo First Middle School (currently the Hibiya High School ) and the First Higher School, Japan (now the University of Tokyo's College of Arts and Sciences faculty). He graduated from the Mathematics Department of the University of Tokyo in 1951; he was a special research student from 1951 to 1953. At that time, he discovered the true nature of economics in the words of John Ruskin, “There is no wealth, but life.” which was quoted in the foreword to by Hajime Kawakami, and decided to study economics. A paper on decentralized economic planning written by him caught the eye of Kenneth Arrow at the Stanford University, he went to study Economics at Stanford University in 1956 with Fulbright fellowship, and became a research assistant, then assistant professor in 1956, then assistant professor at the University of California, Berkeley in 1960, and ...

Kenneth Arrow
Kenneth Joseph Arrow (23 August 1921 – 21 February 2017) was an American economist, mathematician, writer, and political theorist. He was the joint winner of the Nobel Memorial Prize in Economic Sciences with John Hicks in 1972. In economics, he was a major figure in post-World War II neo-classical economic theory. Many of his former graduate students have gone on to win the Nobel Memorial Prize themselves. His most significant works are his contributions to social choice theory, notably "Arrow's impossibility theorem", and his work on general equilibrium analysis. He has also provided foundational work in many other areas of economics, including endogenous growth theory and the economics of information. Education and early career Arrow was born on 23 August 1921, in New York City. Arrow's mother, Lilian (Greenberg), was from Iași, Romania, and his father, Harry Arrow, was from nearby Podu Iloaiei. The Arrow family were Romanian Jews. His family was very supportive of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order Of Culture
The is a Japanese order, established on February 11, 1937. The order has one class only, and may be awarded to men and women for contributions to Japan's art, literature, science, technology, or anything related to culture in general; recipients of the order also receive an annuity for life. The order is conferred by the Emperor of Japan in person on Culture Day (November 3) each year. It is considered equivalent to the highest rank (Grand Cordon) of the Order of the Rising Sun, the Order of the Sacred Treasure, and the Order of the Precious Crown. The only orders that Japanese emperors bestow on recipients by their own hands are the Collar of the Supreme Order of the Chrysanthemum, the Grand Cordon of each order, and the Order of Culture. The badge of the order, which is in gold with white enamel, is in the form of a Tachibana orange blossom; the central disc bears three crescent-shaped jades ('' magatama''). The badge is suspended on a gold and enamel wreath of mandarin or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uzawa Condition
In macroeconomics, the Inada conditions, named after Japanese economist Ken-Ichi Inada, are assumptions about the shape of a function, usually applied to a production function or a utility function. When the production function of a neoclassical growth model satisfies the Inada conditions, then it guarantees the stability of an economic growth path. The conditions as such had been introduced by Hirofumi Uzawa. Statement Given a continuously differentiable function f \colon X \to Y, where X = \left\ and Y = \left\, the conditions are: #the value of the function f(\mathbf) at \mathbf = \mathbf is 0: f(\mathbf)=0 #the function is concave on X, i.e. the Hessian matrix \mathbf_ = \left( \frac \right) needs to be negative-semidefinite. Economically this implies that the marginal returns for input x_ are positive, i.e. \partial f(\mathbf)/\partial x_>0, but decreasing, i.e. \partial^ f(\mathbf)/ \partial x_^<0 #the |
Uzawa Iteration
In numerical mathematics, the Uzawa iteration is an algorithm for solving saddle point problems. It is named after Hirofumi Uzawa and was originally introduced in the context of concave programming. Basic idea We consider a saddle point problem of the form : \begin A & B\\ B^* & \end \begin x_1\\ x_2 \end = \begin b_1\\ b_2 \end, where A is a symmetric positive-definite matrix. Multiplying the first row by B^* A^ and subtracting from the second row yields the upper-triangular system : \begin A & B\\ & -S \end \begin x_1\\ x_2 \end = \begin b_1\\ b_2 - B^* A^ b_1 \end, where S := B^* A^ B denotes the Schur complement. Since S is symmetric positive-definite, we can apply standard iterative methods like the gradient descent method or the conjugate gradient method to : S x_2 = B^* A^ b_1 - b_2 in order to compute x_2. The vector x_1 can be reconstructed by solving : A x_1 = b_1 - B x_2. \, It is possible to update x_1 alongside x_2 during the iteration f ...

Uzawa–Lucas Model
The Uzawa–Lucas model is an economic model that explains long-term economic growth as consequence of human capital accumulation. Developed by Robert Lucas, Jr., building upon initial contributions by Hirofumi Uzawa, it extends the AK model by a two-sector setup, in which physical and human capital are produced by different technologies. The Uzawa–Lucas model is part of endogenous growth theory. Background Lucas approaches in a series of papers published in the 1970s were a challenge to the classic principles of Keynesian economics when he suggested an amassed version of microeconomics models and then emphasized on human capital accumulation. In his 1988 dissertation, using Ramsey framework and Cobb–Douglas production function Lucas gave more attention to formal education rather than learning-by-doing Learning by doing refers to a theory of education. This theory has been expounded by American philosopher John Dewey and Latinamerican pedagogue Paulo Freire. It's a ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
