Answer:
Required return 10.27%
Dividend yield 5.77%
Expected capital gains yield 4.5%
Explanation:
Calculation for required return using this formula
A. R = (D1 / P0) + g
Let plug in the formula
Required return = ($2.30 / $39.85) + .045
Required return = .1027*100
Required return= 10.27%
Therefore Required return is 10.27%
Calculation for dividend yield using this formula
Dividend yield = D1 / P0
Let plug in the formula
Dividend yield = $2.30 / $39.85
Dividend yield = .0577*100
Dividend yield = 5.77%
Therefore Dividend yield is 5.77%
Calculation for the expected capital gains yield
Using this formula
Expected capital gains yield=Required return-Dividend yield
Let plug in the formula
Expected capital gains yield=10.27%-5.77%
Expected capital gains yield=4.5%
Therefore Expected capital gains yield is 4.5%
Answer: D. All of the above
Explanation: The three options listed could explain why the productivity of labor increased with a reduction in the quantity of labor hired. The law of diminishing returns states that as more and more inputs of production are added, a time comes in when additional inputs causes no corresponding increase in productivity. At points like this a reduction in the input added would restore productivity.
Reducing the amount of labor obviously is a labour saving technical change. Changes in organizational innovation can also result in changes in productivity.
Answer:
The correct answer is: an increase; fall; substitutes; decrease; complements; increase.
Explanation:
Technological improvement has lowered the cost of producing cell phone batteries. This reduction in the cost of production will cause the price of cell phone batteries to decline. Since batteries are used as inputs in the cell phone. The reduction in the price of inputs means that the cost of production would decrease. The firms will be able to supply more at the same cost. The supply, as a result, will increase. The supply curve will shift to the right. The price of cell phones will decline.
Cell phones and landlines are substitutes. They can be used in place of each other. A decrease in the price of cell phones would cause the demand for landlines to decrease as the consumers will prefer a cheaper substitute.
The cell phones and applications, however, are use complements. They are used together. So when the price of cell phones decrease and its demand increase, the demand for cell phone applications will increase as well.
