Why do people engage in health deteriorating activities?
Individuals are maximising their utility function, these behaviours may be addictive
What is time preference?
People value present utility more than future utility. The present value of utility is discounted.
How do governments try to change behaviours that decrease health and how effective are they?
Offering incentives: difficult for addictive habits
Taxation: moved to inelastic demand, large revenue earner, poor at reducing consumption, also increases crime
Prohibition: smoking ban in public places
Encourage substitutes: no direct subs, expensive
