Economists Kenneth Chay and Michael Greenstone found that in the two years following the passage of the Clean Air Act of 1970, t

he sharp reduction in air pollution also led to a decline in infant deaths. Although this and other studies provide compelling evidence of the link between pollution and infant health, it is not clear that reductions from the much lower levels of ambient pollution today would have the same effect. Which of the following reasons could explain this?
A) The cost of pollution abatement today is much higher than it was in the 1970s. Thus, it would be far more costly to achieve the same level of benefit today as the benefit achieved in 1970.
B) When levels of pollution are high, the marginal benefit of reducing pollution also is high. It follows therefore that the benefit of reducing air pollution in 1970 would be much higher than the benefit from a proportional reduction in air pollution today when the level of pollution is much lower.
C) Today, the level of pollution is much higher. Therefore, it will take a much larger reduction in air pollution to reap benefits similar to those in 1970.
D) When levels of pollution are high, the marginal benefit of reducing pollution is low. Therefore, it was necessary to significantly reduce air pollution in 1970 before benefits could be realized. Today, when the level of pollution is much lower, such drastic measures are unnecessary.

Answer: B) When levels of pollution are high, the marginal benefit of reducing pollution also is high. It follows therefore that the benefit of reducing air pollution in 1970 would be much higher than the benefit from a proportional reduction in air pollution today when the level of pollution is much lower.

Explanation:

Marginal benefits follow a returns to scale model which means that overtime, the benefits received per additional unit of output is less than the benefit before it.

In the context of pollution, there was much more pollution in 1970 so reducing pollution gave a high marginal benefit. As the air became cleaner however and pollution dropped, the benefit began decreasing because there was less pollution to clean and benefit from.

Adam is a traveling salesperson for Peter Petri Plumbing Supply Corp. Adam has express authority to solicit orders from customer
Juliette [100K]

Answer:

Explanation:

Liability of Petri:

On all the purchases, if payment is made within 30days from delivery, Petri gave the authority of a 5% discount to Adam. Upon extension of credit to customers,  no terms were given to Adam.

In the case under consideration, Adam explicitly gave a false representation of his authority to get more sales on his account and thus, Petri is NOT accountable to John on his terms with Adam.

Liability of John:

Being a customer to Petri, John has to discover the detailed terms on discount and other payment terms with Petri when he called Petri. John is also accountable to make clarifications whether Adam has the authority to give a 10% discount and making payment in three installments.

In the case under consideration, John has failed to find the exact details on whether Adam has the authority to give a 10% discount. Thus, he is accountable to make the payment of $9500 in 30days.

Alik [6]

Answer:

All answers are correct except Money Supply

Explanation:

Fiscal policy affects aggregate demand through government spending and taxes. Government may increase taxes to increase revenue or discourage the consumption of a product. On the flipside, they may reduce taxes to stimulate spending, redistribute income, increase aggregate demand among other objectives.

Trade policy is a fiscal policy as government can use it to control aggregate demand by placing embargo on the importation of certain products to reduce the demand of such products in the local economy.
