The Power of Economics

  • Studying economics helps explain everyday phenomena, from customer service quality to environmental protection laws.

Key Concept: Incentives

  • Incentives are rewards or penalties that influence people's choices and behavior.
  • Good incentives can dramatically change outcomes, as seen in historical examples.

Historical Example: Prisoner Transport to Australia

  • British captains were originally paid per prisoner taken on board, not per prisoner delivered alive.
  • High mortality rates continued despite public outrage and regulations promoting humane treatment.
  • Changing the incentive—paying captains for prisoners who arrived alive—increased survival rates to 99%.
