In this paper, we set out the Japanese Economic Model (JEM), a large-scale macroeconomic model of the Japanese economy. Although the JEM is a theoretical model designed with a view to overcoming the Lucas (1976) critique of traditional large-scale macroeconomic models, it can also be used for both projection and simulation analysis. This is achieved by embedding a mechanism within which "short-run dynamics," basically captured by a vector autoregression model, eventually converge to a "short-run equilibrium," which is defined using a dynamic general equilibrium-type model.
