When the country’s economy is expanding, AB Investment Company is optimistic and expects a MARR of 15% on new investments. However, in a receding economy the expected return is 8%. Normally a 10% per year return is anticipated. An expanding economy causes the estimates of project life to go down about 20%, and a receding economy causes the life values to increase about 10%.
