To reduce cooling electricity consumption in an industrial plant, it is proposed to install an absorption refrigeration system running on solar energy. The absorption system costs $300,000 and the operating and maintenance expenses are $8000 per year. It is estimated that this absorption system will save $27,500 per year from the electricity they save. The lifetime of the system is expected to be 20 years with an average annual inflation-adjusted interest rate of 4 percent. The system will have no salvage value after 20 years of its lifetime. Would you support this project from an economic point of view? How would you evaluate this project if the inflation-adjusted interest rate is 2 percent?
Factors that increase costs and prices—especially for materials and manufacturing costs sensitive to market, technology, and labor availability—can be considered separately using the real interest rate, i, the inflation rate, f, and additional increases that grow at a geometric rate, g (commonly due to maintenance and repair cost increases as machinery ages). The future amount is calculated based on a current estimate by using the relation: F = P(1 + i)n (1 + f )n (1 + g)n = P[(1 + i) (1 + f ) (1 + g)]n The current cost to manufacture an electronic subcomponent is $145,000 per year. Provided the average annual rates for i, f, and g are 8%, 4%, and 3%, respectively, determine the equivalent future cost (a) in 3 years, and (b) in 8 years.
Texas Governor Rick Perry promised to put hundreds of cameras on the Texas-Mexico border and broadcast the video over the Web so that anyone, anywhere could become a border patroller, helping root out border crime and illegal crossings. As part of that project, Texas secured a federal grant for $3 million that paid for 200 mobile cameras in strategic high-traffic areas. If the 200 cameras are considered to be equivalent to 20 border patrol agents, each with an annual salary of $75,000, what is the rate of return over a 3-year project period?

To save for retirement, you will invest $1,200 a month in a stock account in real dollars and $545 a month in a bond account in real dollars. The effective annual return of the stock account is expected to be 11 percent and the bond account will earn 7 percent. When you retire, you will combine your money into an account with an effective annual return of 8 percent. The inflation rate over this period is expected to be an effective annual rate of 4 percent. a.
