A fractional perspective to the bond graph modelling of world economies

摘要: Inspired in dynamic systems theory and Brewer’s contributions to apply it economics, this paper establishes a bond graph model. Two main variables, set of inter-connectivities based on nodes links (bonds) fractional order dynamical perspective, prove be good macro-economic representation countries’ potential performance nowadays globalization. The estimations time series for 50 countries throughout the last decades confirm accuracy model importance scale economic performance.
