The marginal benefit that gained by reducing pollution should be more than marginal cost used to reduce pollution.
Explanation:
In order to reduce the net cost for pollution reduction the marginal benefit should be more than marginal cost. If the marginal benefit is more than marginal cost then it will be good for the society . Marginal benefit reduces when there is increase in consumption , when the marginal cost is more than marginal benefit which means by consuming one extra unit the consumer is not getting the satisfaction.
Answer:
b. aggregate demand shifts right
Explanation:
When the aggregate demand curve shifts right, the quantity of output demanded for a given price level rises. Therefore, a shift of the aggregate demand curve to the right represents an economic expansion.
Answer:
Suppose that the number of students with an allergy to pencil erasers increases, causing more students to switch from pencils to pens in school.
- This will shift the demand curve to the right, increasing the total demand at all price levels.
Moreover, the price of ink, an important input in pen production, has increased considerably.
- This will shift the supply curve to the left, increasing the price of pens at every demand level.
What is sure is that the price of pens will increase. It is likely that the quantity demanded increases, but the extent by which the quantity demanded will increase is unknown.
Answer:
D, a pareto diagram
Explanation:
The pareto diagram was named after the discoverer of the diagram/technique, Vilfredo Pareto. He used the diagram in his study of wealth and poverty in Europe in the 1900s.
The pareto diagram is a bar chart that ranks related events in decreasing other of occurrence. It contains both a bar and line graph. The individual events are recorded by the bar while the total event is recorded by the line graphs.
In the above question, for Clarissa to identify defects, she has to use Pareto diagram which will have the defects represented by the bar and the total production process by the line graph. This helps her to find out the stage in production where the defects started from and how much effect it has onn the production process.
