  2. Continuing the problem above, how much P would be socially optimal based on the Samuelson condition?

  3. What effect do violent movies have on violence? What mechanism drives that effect? What about close football games? What mechanism drives that effect?

  4. What is the difference between systemic violence and pyscho-pharmacological violence and why do those matter in regards to the debate around the prohibition of illegal drugs?

  5. What is CBT and what did we learn about the impacts of CBT based on the pilot projects in Chicago?

  6. Doleac (2015) finds that DNA databases reduce crime substantially. Based on the paper and our classroom discussion, what are at least two ways DNA databases could reduce crime?

  7. List three ways to reduce crime based on Becker’s model

  8. Suppose you used the freedom of information act (FOIA) to request data on traffic stops in Eugene. You find that for men and women the following patterns emerge for















    Search Rate
    Females.235
    Males.382


Your friend working for the daily emerald wants to run a story suggesting that the police are biased against males. Based upon your knowledge and our discussion of statistical discrimination and searches, is this enough evidence to suggest the police are biased against males? Why or why not?

9.Continuing the problem above, what if the hit rate for searches is .571 for females. What is an example of a hit rate for males that would suggest that police are biased against males?

10.Why is it challenging to estimate whether the death penalty reduces crime based on our reading and classroom discussion?

change in violence? Is it statistically significant at the 95 percent level?

b.Of the states listed in the table, which would you most prefer as a control group fora difference-in-difference estimator? Why? What is the key assumption for the difference- indifference estimator to be unbiased?

Continued from Question on previous page)

c.With your answer to part b, calculate the difference-in-difference estimator. Is the difference-in-difference estimate statistically different from zero at the 95 percent level?

 

d.Write down the regression model based which would represent difference-in-difference estimator. What are the values of the coefficients in the regression (derived from the data in the table).

 


  1. Suppose there is a single gang in Eugene responsible for distributing heroin run by Glen Waddell. The (inverse) demand function for heroin is P=1003- 1 𝑄. The cost function for heroin is

10 3*Q+500. Suppose 1 person overdoses for every 20 units of heroin sold.

a.What is the baseline price and quantity of heroin sold in

b.How many people are overdosing in Eugene (you can round if necessary)?

 

c.Suppose the police consider planting a wire. After doing so, the gang will split up with 1 gang run by Caroline Weber and another run by Ben Hansen. They compete as Cournot competitors. Show the reaction function for firm 1 is 1𝑄1 = 5000 − 2 𝑄2. Also find the reaction function for firm 2. What happens to the price and quantity of heroin sold in Eugene? What about the number of overdoses (you can round if necessary)?

d.Given your answer in the part C, what does this tell you about the role of market power in illegal drug markets and drug traffic organizations? In other words, do monopolies increase or decrease social welfare?
