Economics Flashcards
Nominal interest rate:
rate of interest for a given period (usually a year)
Effective Interest Rate:
actual rate of interest, which accounts for the interest amount accumulated over a given period
What is APR?
Annual Percentage Rate ~ the rate of interest that banks state for interest arrangements.
Effective Annual Interest Rate:
the rate that truly represents the interest earned or paid in one year — that is, compounding is considered.
Which part of the period is an annuity paid?
Payments are made at the start of each period rather than the end for an annuity due
Steps when the payment period is equal to the compounding period.
Step 1: Identify the number of compounding periods (M) per year.
Step 2: Compute the effective interest rate per payment period (i).
i = r/M
Step 3: Determine the total number of payment periods (N).
N = M × (number of years)
Steps for when compounding occurs at a different rate than payment.
Step 1: Identify the following parameters:
M = number of compounding periods
K = number of payment periods
C = number of interest periods per payment period
Step 2: Compute the effective interest rate per payment period.
Step 3: Find the total number of payment periods
Step 4: use i and N in the appropriate compounding formula
What does mutually exclusive mean?
A project is excluded if another project is chosen.
What is an independent investment project?
Costs and benefits of one project do not depend on whether another is chosen
You have an investment with complex interest rates (more than one sign change). Which method do you use for recommending the project?

What is the only concern when evaluating a capital investment?

List 6 Cash Outflows:
- Purchase of new equipment
- Investments in working capital
- Manufacturing, operating, and maintenance costs
- Leasing expenses
- Interest and repayment of borrowed amounts
- Income taxes and tax credits
List 5 cash inflows:
- Borrowed funds
