Overview

This lecture introduces the study of economics, focusing on the concept of incentives and how understanding economics changes how you view the world.

The Power of Economics

  • Economics influences how we understand everyday life and major social issues.
  • The field examines how people make choices and how they should make choices under scarcity.
  • Learning economics helps make informed decisions in areas like careers, parenting, and education.

The Importance of Incentives

  • Incentives explain why service varies between businesses, such as restaurants versus cable companies.
  • Sometimes, regulations meant to protect can have the opposite effect if incentives are misaligned.
  • Companies may support costly regulations if it benefits them against competition.

The Sea Captain Example

  • In 1787, British prisoners shipped to Australia faced inhumane conditions due to payment incentives.
  • Appeals to emotion and regulation failed to improve prisoner survival rates.
  • Paying captains for prisoners delivered alive changed incentives, increasing survival rates to 99%.
