Difference-in-Difference
In the beginning of 2001, North Dakota legalized fireworks. Suppose you are interested in
studying the effect of the legalizing of fireworks on the number of house fires in North
Dakota. Unlike North Dakota, South Dakota did not legalize fireworks and continued to ban
them. You decide to use a Difference-in-difference (DID) Model. The numbers of house fires
in each state at the end of 2000 and 2001 are as follows:
Number of house fires in Number of house fires in

Show your working for full credit. (10 points)
b. Can we interpret the change in the outcome for the treatment group between 2000
and 2001 as the causal effect of legalizing fireworks on number of house fires?
Explain your answer. (10 points)

Regression Discontinuity
Birth weight is used as a common sign for a newborn's health. In the United States, if a baby
has a birthweight below 1500 grams, the newborn is classified as having “very low birth
weight". Suppose you want to study the effect of having very low birth weight on the number
of hospital visits made before the baby's first birthday. You decide to use Regression
Discontinuity to answer this question. The graph below shows the RD model:

While laptop usage can help students take lecture notes faster, some argue that the laptops may be a source of distraction for the students. Suppose you are interested in looking at the effect of using laptops in class on the students' final exam scores out of 100. You decide to conduct a randomized control trial where you randomly assign some students at UIC to use a laptop in class and other to not use a laptop in class.

Discuss the advantages and disadvantages of an in-kind subsidy versus a cash grant. Use a graphical illustration to support your arguments. [15] 18. Redistributive expenditure can take the form of direct cash transfers (grants) and/or in-kind subsidies.
