1.A labor market contains coal mines A and B, which are identical except that mine A has put inplace a policy providing safety masks worn by miners that reduces the risk of dust inhalationinjuries for workers in mine A. Imagine mine A now closes down and the workers from mine Aare hired by mine B. What changes, if any, might you predict in the job risk and pay of thepersons who previously worked in mine A but now work in mine B. How might your answerchange if the safety device was an explosion detection system for the mine?a.A self-driving car company releases a high-quality study proving that its new model can reduceyour risk of death in an automobile accident over the life of the car from 2 in 10,000 to 1 in10,000, a claim no other self-driving care company can make. However, the new model costs$10,000 more than other cars to make. What would you expect to happen to the price of thiscompany's stock following this announcement?b.

1. A wood manufacturer must decide whether to merge with a larger company to make more investments. If they merge and it is a good sales year, there will be a $910,000 profit; if they merge and it is a poor sales year, there will be a deficit of $ 330,000. If they do not merge and it is a good sales year there will be a $525,000 profit; if they do not merge and it is a poor sales year there will be a $97,000 profit. If the probability of a good sales year is 0.26 and the probability of a poor sales year is 0.76, would merging with the larger company maximize the expected profit?
Kentville, a community of 10,000 people, resides next to a krypton mine, and there is a concern that the emission from the krypton smelter have resulted in adverse effects. Specifically, Kryptonosis seems to have killed 12 of Kentville’s inhabitants last year. A neighboring community, Lanesburg, has 25,000 inhabitants and is far enough from the smelter to not be affected by the emission. In Lanesburg, only three people last year died of Kryptonosis. Given that the number of deaths in Kentville and their causes last year were: Heart attack=7 Accidents=4 Kryptonosis=12 Other=6 What is the risk of dying of Kryptonosis in Kentville relative to non-contaminated locality?What is the risk of dying of Kryptonosis in Kentville relative to deaths due to other causes? How many times the chance of dying of Kryptonosis compared to dying of accidents ? How many times the chance of dying of Kryptonosis compared to Other causes?
