(Figure: Production Possibilities and Circular-Flow Diagram) Look at the figure
Production Possibilities and Circular-Flow Diagram. Assume the two figures represent
the same economy. Suppose that in the circular-flow diagram there is a significant
decrease in the amount of labor flowing to the firms that produce coconuts. If all other
variables remain unchanged, this adjustment in the economy would be best represented
in the production possibilities figure by a move from point A toward:
A) point A (no movement).
B) point B (a decrease in coconut production and an increase in fish production).
C) point C (a decrease in coconut production).
D) point D (an outward shift of the entire curve).
Suppose that some firms in a perfectly competitive industry earn negative economic
profits. In the long run, the:
A) short-run industry supply curve will not shift.
B) short-run industry supply curve will shift to the left.
C) number of firms in the industry will not change.
D) number of firms in the industry will increase.
