The net trade balance is measured as the total value of exported goods and services minus the total value of imported products.
A trade surplus means that X>M – therefore aggregate demand (AD) will increase.
A trade deficit means that M>X – therefore AD will fall. There is a net leakage from the circular flow of income.
If X=M, then the trade balance is zero, external trade will have a neutral effect on AD.
