Assessment design
Multiple-choice: select the single best answer; distractors represent common
conceptual confusions.
Essay: responses should define the concept, explain the mechanism, and use a
relevant example where appropriate.
Numerical or policy applications: show assumptions and intermediate reasoning
when calculations are involved.

B. People alter behavior when rewards, penalties, or relative prices change.
C. Voluntary exchange can make both parties better off by allowing specialization.

B. People alter behavior when rewards, penalties, or relative prices change.
C. Voluntary exchange can make both parties better off by allowing specialization.
