T

82

F

T

85
Q

13. A tax collected from buyers generates a smaller deadweight loss than a tax collected from sellers.
A

F
Taxes collected from either the buyers or the sellers are equivalent. That is why economists simply use a tax wedge when analyzing a tax and avoid the issue altogether.

5. When a production function gets flatter, the marginal product is increasing.
A

F
Marginal product is the slope of the production function, so marginal product is decreasing when the production function gets flatter.

A

T

94
Q 
#CHT13
7. If the production function for a flrm exhibits diminishing marginal product, the corresponding total-cost curve for the firm will become flatter as the quantity of output expands.
A

F
Diminishing marginal product means that it requires ever greater amounts of an input to produce equal increments of output so total costs rise at an increasing rate.

#CHT13
8. Fixed costs plus variable costs equal total costs.
A

T

96
Q 
#CHT13
9. Average total costs are total costs divided by marginal costs.

103
Q
