Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What characterizes a short-run production function?

Answer: At least one input is fixed. Constraints prevent changing all production factors.

Flashcard 2: Find the MPL when total output rises from 50 to 60 as labor increases from 5 to 6.

Answer: $10$. Change in output ($10$) divided by change in labor ($1$).

Flashcard 3: State the significance of the production possibilities frontier in relation to production functions.

Answer: It demonstrates maximum output possibilities. Connects production theory to macroeconomic concepts.

Flashcard 4: What is the typical shape of a total product curve initially?

Answer: Increasing at an increasing rate, then at a decreasing rate. Reflects diminishing marginal returns after initial gains.
