Compare absolute advantage vs comparative advantage for two producers, find the mutually beneficial terms of trade, and measure each producer's gains from trade.
Classify any country into one of the five demographic transition model stages from its crude birth and death rates, and see the data point plotted on the classic DTM diagram.
Apply the money multiplier formula to any deposit and reserve ratio, then see deposit expansion round by round in a stack of bank T-accounts.
Draw a production possibilities frontier from your own numbers, classify any point as efficient, inefficient, or unattainable, and compute the opportunity cost step by step.
Apply the tax multiplier formula and the spending multiplier formula to any MPC or MPS, and see the rounds-of-spending waterfall converge to the total change in GDP.
