This section introduces the Production Possibilities Frontier as a fundamental tool that demonstrates an economy's production limits, trade-offs, and opportunity costs. It highlights how shifting resources from one good to another results in varying opportunity costs, explains the differences between production efficiency and allocative efficiency, and shows that optimal production occurs where marginal benefit equals marginal cost. Additionally, it explores how economic growth shifts the PPF outward and how comparative advantage leads to gains from trade, all of which are coordinated by market mechanisms, property rights, and the use of money.

a. Draw a graph of Brazil's $P P F$ and explain how your graph illustrates scarcity. b. If Brazil produces 40 barrels of ethanol a day, how much food must it produce to achieve production efficiency? c. Why does Brazil face a trade off on its $P P P$
a. If Brazil increases ethanol production from 40 barrels per day to 54 barrels a day, what is the opportunity cost of the additional ethanol? b. If Brazil increases food production from 2 tons per day to 3 tons per day, what is the opportunity cost of the additional food? c. What is the relationship between your answers to parts (a) and (b)?
Does Brazil face an increasing opportunity cost of ethanol? What feature of Brazil's PPF illustrates increasing opportunity cost?
Define marginal cost and calculate Brazil's marginal cost of producing a ton of food when the quantity produced is 2.5 tons per day.
Define marginal benefit. Explain how it is measured and why the data in the table does not enable you to calculate Brazil's marginal benefit from food.
