Comunicação apresentada na International Conference on Economic Modeling and Data Science, EcoMod2021http://hdl.handle.net/10400.5/22523Through the use of numerical and algebraic matrix representations, the economic adjustments of changes in the monetary flows registered in the national accounts as transactions are measured and modelled, benefiting from the underlying network of linkages. Factors of production, industries, products, and institutions are worked together and the generation, distribution, redistribution, use, and accumulation of income, are all identified in detail. In conjunction with the above-mentioned representations, these features enable the capture of the multiplier effects of changes in the monetary flows involved. These effects expand in different ways throughout the underlying general equilibrium economic system. The result can be interpreted as the economic adjustment to these changes, as reflected at the level of the macroeconomic aggregates. A SAM (Social Accounting Matrix)-based approach is proposed in this study which is applied to Portugal in 2017 – in the form of an experimented to study the economic adjustments of changes associated to fiscal policy. This experiment is carried out for the real estate activities that generated 12% of the domestic income and paid 33% of the taxes on production.engNational AccountsSocial Accounting MatrixMultiplier EffectsReal Estate Taxationconference object
