Main directions of the tax policy in a balanced economy

In article the known mathematical model of the balanced open economy is studied, relations between absolute and relative values of the main macroeconomic indicators are analyzed: between the planned (predicted) size of gross domestic product; public expenditures, investments, consumption, tax burden, balance of payments of the country and their norms, public efficiency, discount rate of the Central Bank of the country, rate of the economic growth of the balanced open economy, inflation. The author theoretically proved the possibility of the achievement of the maximally possible public efficiency of public expenditures, investments and taxes in a perfectly tuned open balanced economy. The offered model can always result ideally (“zero losses” of public efficiency of public expenditures and investments) in the highest possible rate of the economic growth that allows to prove, in turn, scientifically the main directions of the corresponding macroeconomic (financial, tax and budgetary) policy.
