Week 9 Application Assignment (2–3 pages) and Scenarios



Time-Value Formulas and Cost-Benefit Analysis


Scenario 1: Present-Value Calculation

The following simple present value formula shows the effect of discounting on the cost of a public policy. In the formula, the discount rate will be set at
(1 + r)^time
where:
1= a constant
r = a selected interest rate

^time= a period of time, usually a year
The formula is
Cost or Benefit
(1+r)
^time

The calculation occurs like this example of $1,000 over 2 years discounted at 10%:
$1,000 = $1,000 = $1,000 = $826.44
(1+10 percent)²
(1.1)²
1.21
Let's say a city wants to open a recycling center aimed at reducing waste. The total benefits of the program are valued at $1,000,000. Three different discount rates are estimated at 5%, 6%, and 7%. The time period for receiving the benefits of the program is two years.

Scenario 2

In doing the following exercise, please refer to the discussion in the designated pages of Chapter of
Fiscal Administration
on cost benefit and cost-effectiveness analysis. Cost-benefit analysis is a technique that assumes all costs and benefits can have a dollar value attached to them. It is a tool and should not be used as the sole basis for decision making. The result of a calculation is a ratio between costs and benefits. After all other calculations have been made the analysis needs to conclude with the calculation the ratio between costs and benefits. If in the ratio costs exceed benefits the project advice is to not accept the project and to consider accepting the project if benefits exceed costs. Consider the following example from the fictitious Swobodaville to build a Community Windmill Renewable Energy Project. The following has been agreed upon.
1. Land is already owned. The price of a new is windmill is $150,000. A minimum of fifty windmills are needed to achieve desired efficiency compared to the current coal burning method.
2. Staff training costs over three years when considering direct costs including loss of productive hours while in training will be $55,000 for each of the ten specialists to be hired.
3. The annual operating and maintenance costs of the machine in the three-year period will be $35,000 per windmill.
4. The cost of shutting down a portion of the coal plant to achieve the same energy production as the windmills is $1,000,000.
5. There will be a decrease in staff productivity compared to coal burning operations. It was calculated on the average hourly rate of the ten specialized staff of $55 and the number of hours added over the three year-period, 450. Three current coal plant workers who will lose their jobs is three at a wage of $35 per hour.
6. As a widely supported community project with an investment in every aspect of the community’s well being, quality of life expected from reductions in pollution is considered in the cost calculation. The medical center conducted an analysis has concluded that the value of increased life expectancy should be included as a benefit to the community. The quality of life of 5,000 residents is expected to be increased by an average of dollars over three years. The average benefit of a resident (including all men, women and children) over a three year period is estimated to be $1500.
7. The three year savings on other pollution damage to buildings and grounds calculated by the Sierra Club is $7,000,000.
Scenario 1:

• Calculate the present value at each interest rate.


• Note and discuss what happens to the present value at each interest rate.

Scenario 2:

• Calculate the cost-benefit ratio.


• Determine whether the ratio is positive or negative.


• If positive, would you go ahead and replace a portion of
  thecoal-burning operationor the whole operation? Why or why not?
