Superstatistics of Labour Productivity in Manufacturing and Nonmanufacturing Sectors PDF Icon
(Published in Special Issue Reconstructing Macroeconomics)


Labour productivity distribution (dispersion) is studied within the framework of statistical physics and the result is compared with the outcome of the empirical analysis. Superstatistics is presented as a natural theoretical framework for the productivity distribution. The demand index κ is proposed within this framework as a new business index. Productivity analysis is made on the Japanese data covering small-to-medium to large firms from 1996 to 2006 and the power-law for both firms and workers is established. The demand index κ is evaluated in the manufacturing sector. A new discovery is reported for the nonmanufacturing (service) sector, which calls for an expansion of the superstatistics framework to include the negative temperature range.
