Economic Concepts, Scarcity, and PPC

The fundamental economic problem, which forces individuals, businesses, and governments to make choices, is:

• The difficulty in defining "needs" versus "wants."

• Rational behaviour leading consumers to always seek maximum satisfaction.

• Limited resources meeting unlimited wants.

• The Production Possibility Curve (PPC) being bowed outward.

You have €20. You choose to purchase new headphones for €19.99 (Option B). Your next best alternative was Option A, going to the cinema with friends (ticket plus snacks costing €10). What is the opportunity cost of choosing the headphones?

• The €19.99 spent on the headphones.

• The cinema trip with friends. (Option A)

• The total value of Option A and Option B combined.

• Any money already saved up for the PS5 game.

Which factor of production refers to the individual skill and risk-taking ability required to organise Land, Labour, and Capital to start or run a business?

• Land

• Labour

• Capital

• Enterprise

"Free" bus travel for residents, paid for using public funds, is still considered an economic good, rather than a free good, because:

• There are never enough bus seats during peak hours, creating scarcity.

• It requires scarce resources to operate and is funded by taxes.

• The government makes the decision on routes, not the market.

• The service involves a choice, and every choice has an opportunity cost.

Any production combination of two goods that falls exactly on the Production Possibility Curve (PPC) indicates:

• The combination is unattainable without new technology.

• Resources are wasted or lying idle.

• Resources are being used efficiently.

• The opportunity cost is constant.

A school tuck shop can produce either Spicy Chicken Sandwiches (X) or Fruit Cups (Y). If the shop currently produces a combination that lies inside its PPC, which statement must be true?

• The shop's resources are being used inefficiently or are idle/wasted.

• The shop is prioritizing profit over fairness.

• The shop needs to acquire new, better equipment to reach that point.

• The shop has achieved constant opportunity cost.

The art lab uses its printing resources to produce either T-Shirts (X) or Posters (Y). They move production from point A (60 T-shirts and 450 Posters) to point B (120 T-shirts and 300 Posters). Assuming points A and B are on the PPC, the opportunity cost of producing the extra 60 T-Shirts is:

• The cost of the new heat press needed to achieve this increase.

• The 120 T-shirts produced at point B.

• 150 posters.

• The wages of the staff printing the items.

The typical Production Possibility Curve (PPC) is bowed outwards (curved away from the origin) because:

• New technology is constantly shifting the curve outward.

• As resources are switched from producing one good to another, they are not equally efficient at producing the new good.

• People are generally irrational when making choices.

• Efficiency means using fewer resources overall.

If Malta’s government invests heavily in staff training and new technology for its industries, resulting in more goods and services being possible across the board, how is this represented on a PPC diagram?

• A movement from an inefficient point to an efficient point along the curve.

• An inward shift of the entire curve (PPC loss).

• The curve becomes a straight line due to constant opportunity cost.

• An outward shift of the entire curve (PPC growth).

The condition of scarcity dictates that choice must be made. This is because choices involve trading off limited resources (like money, time, or land) against:

• Needs, which are limited in quantity.

• Wants, which are unlimited.

• The factors of production.

• Rational behaviour aimed at maximizing profit.
