Explain what is meant by subjective probability.

Can you please research the internet, and provide a business-related example in which subjective probability assessment would likely be used (be sure to cite your sources)?

Can you also provide an example of when you have personally used subjective probability assessment or how you might use it in the future? Thanks!

Quantitative Methods and Analysis:

Subjective probability refers to an approach that shows the consequences that might occur in case previous beliefs are modified so as to get results for the new data (subjective probability, n.d.). Subjective probability assessment can be used in risk analysis and decision making by identifying the exhaustive and exclusive events that will be used by the management in decision making. Subjective probability assessment in business involves the assessment of uncertain events such as the rise in interest rates. The uncertainties of ...

Solution Summary

Quantitative methods and analysis are examined. The business-related assessment are used for subjective probability.

Quantitative Methods

1) The following table shows nominal GDP and an appropriate price index for a group of selected years. Compute real GDP. Indicate in each calculation whether you are inflating or deflating the nominal GDP data.
Year Nominal GDP, Price Index
1960 $ 527.4 22.19
1968 911.5 26.29
1978 2295.9 48.22
1988 4742.5 80.22
1998 8790.2 103.22

2) Suppose an economy's real GDP is $30,000 in year 1 and $31,200 in year 2. What is the growth rate of its real GDP? Assume that population is 100 in year 1 and 102 in year 2. What is the growth rate of GDP per capita?

3) If the CPI was 110 last year and is 121 this year, what is this year's rate of inflation? What is the "rule of 70"? How long would it take for the price level to double if inflation persisted at (a) 2, (b) 5, and (c) 10 percent per year?

4) A firm has fixed costs of $60 and variable costs as indicated in the table on the following page. Complete the table.
a. Graph total fixed cost, total variable cost, and total cost. Explain how the law of diminishing returns influences the shapes of the variable-cost and total-cost curves.
b. Graph AFC, AVC, ATC, and MC. Explain the derivation and shape of each of these four curves and their relationships to one another. Specifically, explain in nontechnical terms why the MC curve intersects both the AVC and the ATC curves at their minimum points.
c. Explain how the location of each curve graphed in question 7b would be altered if (1) total fixed cost had been $100 rather than $60 and (2) total variable cost had been $10 less at each level of output.

5) ROI analysis using DuPont model.
a. Firm D has net income of $27,900, sales of $930,000, and average total
assets of $465,000. Calculate the firm's margin, turnover, and ROI.
b. Firm E has net income of $75,000, sales of $1,250,000, and ROI of 15%.
Calculate the firm's turnover and average total assets.
c. Firm F has ROI of 12.6%, average total assets of $1,730,159, and turnover
of 1.4. Calculate the firm's sales, margin, and net income.

6) Basic CVP Exercises
Each problem is unrelated to the others.

1. Given: Selling price per unit, $20; total fixed expenses, $5,000; variable expenses per unit, $15.
Find break-even sales in units.
2. Given: Sales, $40,000; variable expenses, $30,000; fixed expenses, $7,500; net income, $2,500.
Find break-even sales in dollars.

3. Given: Selling price per unit, $30; total fixed expenses, $33,000; variable expenses per unit, $14.
Find total sales in units to achieve a profit of $7,000, assuming no change in selling price.

4. Given: Sales, $50,000; variable expenses, $20,000; fixed expenses, $20,000; net income,
$10,000. Assume no change in selling price; find net income if activity volume increases 10%.

5. Given: Selling price per unit, $40; total fixed expenses, $80,000; variable expenses per unit, $30.
Assume that variable expenses are reduced by 20% per unit, and the total fixed expenses are increased
by 10%. Find the sales in units to achieve a profit of $20,000, assuming no change in selling price.
