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.

Derk owns 250 shares of stock in Rose Corporation. The remaining 750 shares of Rose are owned as follows: 150 by Derk’s daughter
Mama L [17]

Answer:

720 shares

Explanation:

Given that,

Derk owns = 250 shares of stock in Rose Corporation

750 shares of Rose are owned as follows:

Derk’s daughter owns = 150

Derk’s aunt = 200

Shares in the partnership holding:

= 400 shares × Interest

= 400 shares × 80%

= 320 shares

Therefore,

Number of shares Derk owns in Rose Corporation:

= Own shares + Daughter's shares + Shares in the partnership holding

= 250 + 150 + 320

= 720
