Some Complex Dynamics for a Multisectoral Economy

The paper illustrates a novel experimental approach to the dynamics of an observed economy described as a sequence of regime changes, and to compare it with traditional multisectoral dynamics. It focuses on its global dynamic behavior and introduces a corresponding practical notion of structural change. The approach is best suited to qualitative comparisons of system dynamics, across spatially and/or temporally distributed systems (whole economies, regions, sectors). It deploys a computational heuristics, in which system dynamics is computer-simulated for theoretical purposes on the basis of empirically observed data. Some preliminary results of an exercise with Italian data for employment, accumulation and a productivity in tbe last two decades, are reported.
