Rubber:
Initial investment: $159,000
Annual cost: $36,000
Annual revenue: $101,000
Salvage value: $12,000
Useful life: 10 years
Using the cotermination assumptions, a study period of 6 years, and a MARR of 9%, what is the present worth of the rubber
alternative? Assume that the rubber alternative's equipment has a market value of $18,000 at the end of Year 6.
Richard has just opened a new restaurant. Not being good at
deserts, he has contracted with Carla to provide pies. Carla’s costs are $10 per
pie, and she sells the pies to Richard for $25 each. Richard resells them for $50,
and he incurs no costs other than the $25 he pays Carla. Assume Carla’s costs go
up to $30 per pie. If courts always award expectation damages, which of the
following statements is most likely to be true?

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

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.

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.
