  • Benefits more than the individual, e.g., increases productivity and reduces crime rates in society.

Demerit Goods

  • Generate negative externalities, which are costs to third parties who are not involved in the consumption.
• Example: Cigarettes
  • Harmful health impacts on people around smokers.

Externalities

• Definition: A benefit or cost incurred by a third party who is not involved in a transaction.
• Positive Externality Example: A pleasant smell from a bakery that you enjoy without buying or producing anything.
• Negative Externality Example: Health risks from secondhand smoke.

Consumption Patterns

• Merit Goods:
  • Often under-consumed due to lack of awareness about their full value.
  • Example: Education is not fully valued, leading to lower consumption than would be beneficial.
• Demerit Goods:
  • Often over-consumed due to underestimation of harm.
  • Example: Cigarettes are consumed more than advisable, despite negative spillover effects.

Conclusion

• Understanding of externalities and merit/demerit goods can explain consumption behaviors.
