Each point on the curve shows potential total output for the economy, which is the maximum feasible output of one good, given a feasible output quantity of the other good. Macroeconomics is ‘non-experimental’: like, e.g., history, macro-economics cannot conduct controlled scienti fic experiments (people would complain about such experiments, and with a good reason) and focuses on pure observation. Advanced Placement Macroeconomics (also known as AP Macroeconomics, AP Macro, APMa, or simply Macro) is an Advanced Placement macroeconomics course for high school students culminating in an exam offered by the College Board..
