Explain and graphically illustrate how an improvement in technology could decrease the total cost
of production.

See Learning Unit 3, and pages 54-55 of the prescribed textbook.
• Technology refers to the productive capabilities of the methods and machines that are
employed in the production process.
• In the Environmental Economics, technologically change plays a significant role because of
its capability of providing ways to produce goods and services with fewer environmental side
effects.
• Furthermore, technologically change provides better ways of handling the quantities of
production residuals that remain.
• In a simple cost model, the technical change shifts the marginal cost curve downward. This
enables the firm to determine how much total production will be reduced because of
technological change.
• The technological progress makes it possible to produce a given increase in output at a
lower marginal cost, as it reduces total production cost.
• total annual cost of producing q* is equal to area b. Thus, the reduction in total cost made
possible by the technologically change is equal to area a.
