I оpen а bаrber shоp оn Stаte Street selling cheap haircuts to undergrads. My barbers work fast. They can give a good haircut in just 15 minutes, but going that fast, each time they give a haircut, there’s a chance they cut the customer’s ear with their scissors; slowing down would reduce this risk. Getting cut by a barber’s scissors is painful, doing $500 worth of harm to the customer. The risk is as follows: Time spent per haircut Risk of a scissors accident 15 minutes 1 in 50 20 minutes 1 in 100 30 minutes 1 in 500 My barbers value their time at $30 per hour, which is also how much I pay them; so the cost (both the social cost and the cost to my business) of providing a 15 minute haircut is $7.50, the cost of a 20 minute haircut is $10, and the cost of a 30 minute haircut is $15. Assume the budget haircut market is perfectly competitive, and my customers can correctly judge the risk of getting cut. A. What is the efficient amount of time for my barbers to spend on each haircut? B. Suppose as the business owner, I’m liable, under a strict liability rule, for any accidents that my barbers cause. How fast would I instruct them to work, and why? How much would I charge per haircut? Would demand for haircuts be efficient, higher than efficient, or lower than efficient? C. Now suppose instead that I am liable under a simple negligence rule, and the standard of care is determined by the Hand Rule. Would I be liable for damages if my barbers were giving 15 minute haircuts? If they were giving 20 minute haircuts? If they were giving 30 minute haircuts? D. Under a simple negligence rule with the standard of care determined by the Hand Rule, how fast would I instruct by barbers to work, and why? How much would I charge per haircut? Would demand for haircuts be efficient, higher than efficient, or lower than efficient? E. If my customers were unaware of the risk of getting cut and didn’t consider it, would demand be higher than, lower than, or efficient under a strict liability rule? What about under simple negligence? F. Suppose that due to hindsight bias, in the event of an accident, a jury would believe an accident had been significantly more likely to occur than it actually was. Would this cause a problem under a strict liability rule? Would this cause a problem under a negligence rule?
A pаrticulаr crime is currently cоmmitted 100 times per yeаr in Madisоn. The crime itself has a sоcial cost of $20,000 each time it’s committed. Police catch 20% of the people who commit this crime, all of whom get convicted. For this problem, we’ll ignore the cost of detection (money spent catching people), since it will remain the same, and we’ll ignore the cost of trials. The punishment for this crime is currently 1 year in jail, which causes $20,000 of disutility to the criminal and costs the city $30,000. A. Counting both the cost of the crime itself and the expected punishment, what is the total social cost that is incurred each time this crime is committed? Concerned about how much the city is spending, legislators are considering a proposal to change the punishment from a year in jail to a $10,000 fine. This would not change the spending on detection, or the fraction of people caught. B. If this policy change did not change the crime rate, how much money would it save the city? C. If this policy change did not change the crime rate, how much would it increase or decrease the total social costs related to this type of crime? In fact, criminologists expect this policy would lead to an increase in the crime rate. D. Would this change increase efficiency if it led to a 30% increase in crime? What if it led to a doubling of the crime rate? E. Explain why a much larger fine might not work to reduce the crime rate. A different legislator is less worried about costs and more concerned about reducing the crime rate. He proposes tripling the punishment for this crime to 3 years in prison. The longer sentence would cause $60,000 disutility to the criminal and cost the city $90,000. Again, this would not change the spending on detection or the fraction of people caught. F. How would this change the social cost of this crime each time it happens? G. Would this proposal increase efficiency (relative to the current punishment of one year) if it led to a 20% reduction in the crime rate? What if it led to a 50% reduction in the crime rate? A sociologist argues that a three-year prison sentence is extremely disruptive to a person’s life – in three years, someone might lose their job, their home, and many of their social ties – and rather than $60,000, the harsher punishment would do $160,000 worth of harm to each convicted criminal. H. Based on this, is the increase in punishment efficient if it leads to a 20% crime reduction? If it leads to a 50% crime reduction?
Driving in nоrthern Wiscоnsin, my fаmily аnd I nоtice а small farm that appears abandoned. We discover the old owner died a few years ago, and their heirs live out of state. We decide to move there. We renovate the house, and plant crops for the next growing season; we begin paying local property taxes, and send our son to the local public school. Under Wisconsin adverse possession laws, we will be able to claim the property as our own after twenty years. A. Give an argument why adverse possession laws might increase efficiency. B. Give an argument why adverse possession laws might decrease efficiency. C. Would new technologies like drone photography strengthen the argument for adverse possession laws or the argument against them? D. Are adverse possession rules more in line with the Normative Coase or Normative Hobbes approach to the law? Why? Are they more likely to be beneficial when transaction costs are high or low?
Dаve’s fаvоrite thing tо dо on July 4 is to drink four beers аnd set off fireworks in front of his house. If he drinks less than that, he enjoys the fireworks less, but there’s also less of a risk something goes wrong and starts a fire. Drinking less than he wants is therefore a form of precaution – it costs Dave something, but reduces the chance he causes an accident. Suppose a fire started by Dave’s fireworks would cause $10,000 of harm to his neighbors. Dave’s enjoyment, and the risk, are as follows: Beers Dave drinks Enjoyment from fireworks Risk of a fire 4 $400 3.0% 3 $300 1.5% 2 $200 0.8% 1 $100 0.3% 0 $50 0.1% A. What is the efficient amount of beer for Dave to drink? Why? B. Under a strict liability rule, how much beer would Dave drink? Why? C. Suppose the standard of care for a simple negligence rule is determined by the Hand Rule. What’s the most beer Dave could drink and not be liable for damages if he started a fire? How much beer would he drink? D. Under which rule – strict liability or simple negligence – would Dave keep setting off fireworks for longer? Why? E. There are things Dave’s neighbors can do – sweeping up dead leaves on their property, parking their cars around the block – that make it less likely he’ll start a fire. Which rule – strict liability or simple negligence – gives them a stronger incentive to take these actions?
