Quasistatically varying log-normal distribution in the middle scale region of Japanese land prices

Atushi Ishikawa

Employing data on the assessed value of land in 1974--2007 Japan, we exhibit a quasistatically varying log-normal distribution in the middle scale region. In the derivation, a Non-…

The log-normal distribution from Non-Gibrat's law in the middle scale region of profits

Atushi Ishikawa

Employing profits data of Japanese firms in 2003--2005, we kinematically exhibit the static log-normal distribution in the middle scale region. In the derivation, a Non-Gibrat's la…

The uniqueness of company size distribution function from tent-shaped growth rate distribution

Atushi Ishikawa

We report the proof that the extension of Gibrat's law in the middle scale region is unique and the probability distribution function (pdf) is also uniquely derived from the extend…

The uniqueness of the profits distribution function in the middle scale region

Atushi Ishikawa

We report the proof that the expression of extended Gibrat's law is unique and the probability distribution function (pdf) is also uniquely derived from the law of detailed balance…

Dynamical change of Pareto index in Japanese land prices

Atushi Ishikawa

We investigate the dynamical behavior in the large scale region of non-equilibrium systems, by employing data on the assessed value of land in 1983 -- 2006 Japan. In the system we…

Annual change of Pareto index dynamically deduced from the law of detailed quasi-balance

Atushi Ishikawa

Employing data on the assessed value of land in 1983 -- 2005 Japan, we investigate the dynamical behavior in the high scale region of non-equilibrium systems. From the detailed qua…
