 the production set has shrunk. the marginal cost of producing the good measured on the Y-axis has fallen. the marginal cost of producing the good measured on the Y-axis has increased. the marginal cost of producing the good measured on the X-axis has fallen.

Question 9

Starting from a pure exchange equilibrium, an increase in the demand for a commodity will result in:

\$320
\$160
\$380
\$240

 \$20 \$35 \$25 \$45

Question 18

Which of the following is a possible explanation for the fall in prices after an industry is monopolized by combining a group of competitors?

 A monopolist faces a downward sloping demand curve. Hence, output expansion leads to lower prices. . A monopolist may reduce prices to make it difficult for other firms to compete. A monopolist can increase profits by reducing price when its cost of production declines due to increased size of the new firm. The fall in price is less than the decline in cost.
