Chapter 2: Questions from textbook

Q5. Consider the production and use of single-use, plastic-shopping bags, and examine their flows along all parts of Figure 2.1. Do the same for paper shopping bags.

Q7. Suppose there is a technological change that allows firms to produce goods and services with less pollution. How would this affect the production possibilities curves of Figure 2.2, and where might society choose to locate itself on this curve?

Concept:

What is Fundamental Balance  equation used in Environmental management? Details of this equation.

a. What is this individual’s total willingness to pay at a consumption level of 4 apples?


b. If the price of organic apples is $2.40, how many apples would this person consume?

3. Below are the marginal willingness-to-pay schedules for organic apples for two individuals. Note the MWTP for John to go from 0 to 1 lb. per week is $6.40. Construct the aggregate marginal

willingness-to-pay (the demand) curve for this group of two people.

4. What are the advantages and disadvantages of using willingness to pay as a measure of value? What are some alternatives?

5. Figure 3.10 illustrates the derivation of an industry supply curve under competitive conditions where each firm receives the same price for its output. What is the relationship of this procedure to the equimarginal principle discussed earlier in the chapter?

Additional Questions:

What is production possibilities curve (PPC), shape and location of PPC?

What do mean environmental sustainability?

What is opportunity costs, marginal costs (MC), social costs?


How technological change affect MC curve?

What is Equimarginal Principle?
