The City of San Antonio is considering various options for providing water in its 50year plan, including desalting. One brackish aquifer is expected to yield desalted water that will generate revenue of $4.1 million per year for the first 4 years, after which less production will decrease revenue by 10% per year each year. If the aquifer will be totally depleted in 23 years, what is the present worth of the desalting option revenue at an interest rate of 8% per year?

To address the Covid Virus situation, government has implemented restrictions that have

prevented many from working. Modeling this as a decrease in the labor supply, present an

predicted to impact the employment level, nominal wage level, real wage level, output level, price

level, and real interest rate level.
