Outline of Final Research Achievements

The central dogma of the current mainstream economics is to assume optimization of the representative agent such as consumer and firm. Now macroeconomics is regarded just as a discipline obtained by uniformly expanding microeconomics to a macroscopic scale. However, we are so open-minded to accept heterogeneity of economic agents as indicated by looking straight at real macroeconomic phenomena. In this research project, we attempt to reconstruct macroeconomics by adopting ideas and methodologies of statistical physics, that is, foundation of "Macro-econophysics". We always respect empirical results. Needless to say, we have to carefully treat real data in which scientific truths are often masked by noises. The research themes in this project includes: 1) empirical analysis of labor productivity distribution together with modelling, 2) labor productivity of small to medium-sized firms and innovation, and 3) dynamical relationship between deflation/inflation and price indices.
