We propose a new method to convert individual daily trajectories into token time series by applying the tokenizer “SentencePiece” to a geographic space divided using the Japan regional grid code “JIS X0,410.” Furthermore, we build a highly ac

We employed the latest version of the world’s largest corporate financial database and identified the following three statistical properties of the physical labor productivity of firms: 1) The probability density function (PDF) of labor productivit

This paper uses census municipal population data for the United States, Italy, and Spain to analyze the statistical properties of their 10-year growth (short-term property). As a result, it was confirmed that the smaller the initial urban population

We analytically derived and confirmed by empirical data the following three relations from the quasi-time-reversal symmetry, Gibrat’s law, and the non-Gibrat’s property observed in the urban population data of France. The first is the relation be

We analytically show that the logarithmic average sales of firms first follow power-law growth and subsequently follow exponential growth, if the growth-rate distributions of the sales obey the extended-Gibrat’s property and Gibrat’s law. Here, t

Financial statements’ big data have the characteristics of “Incompleteness” and “Nonrepresentative”. In this paper, employing the world’s largest commercial database on finance, ORBIS, we first find that the rate of missing data varies de

We directly observed a Cobb–Douglas symmetric plane using the index of surface openness, which is used in geography, and successfully identified it. Based on this observation, we measured the capital shares (capital elasticity) and labor shares (la
