Net exports equal the government sector balance ($200 billion) plus the private sector balance (–$200 billion). So net exports are zero.

12. © 2013 Pearson Solution The link between the government sector balance and the private sector balance is given by the equation: (X – M) = (S – I) + (NT – G) Rewrite the equation as (NT – G) = (S – I) – (X – M) A cut in G will decrease the left side of the equation. If consumption does not increase, then S will increase. To make the right side of the equation decrease, X must increase. CHECKPOINT 34.1
