Given the relationship between Balance of Payments and National Income, for a given level of “I” and “(T – G)”, “S” must be increased to increase BCA. For a given level “S” and “(T – G)”, “I” must be reduced to increase BCA. For a given level of “(S – I)”, “(T – G)” must be reduced to reduce the BCA deficit. Will tariff and non-tariff barriers have impact on BCA deficit?
