A machine purchased 3 years ago for $140,000 is currently too slow to satisfy increased demand. The machine can be upgraded now for $90,000 or sold to a smaller company for $40,000. The current machine will have an annual operating cost of $85,000 per year and a $30,000 salvage value in 3 years. If upgraded, the presently owned machine will definitely be retained for 3 more years. The replacement, which will serve the company now and for at least 8 years, will cost $223,000. Its salvage value will be $50,000 for years 1 through 5, $20,000 after 6 years, and $10,000 thereafter. It will have an estimated operating cost of $65,000 per year. The company asks you to perform an economic analysis at 15% per year using a 3-year planning horizon. Should the company replace the presently owned machine now, or do it 3 years from now

The risk-free rate is 7% and the expected rate of return on the market portfolio is 11%. a. calculate the required rate of return on a security with a beta of 1.92. (do not round intermediate calculations. enter your answer as a percent rounded to 2 decimal places.) b. if the security is expected to return 15%, is it overpriced or underpriced?

A) plot the m1 and m2 money stock in the us from 1990-2015. (hint: you may use the data tools provided by fred.) (b) plot the nominal interest rate from 1960 to 2014. (hint: you can either use the daily interest rates for selected u.s. treasury, private money market and capital market instruments from or the effective federal funds rate fromfred.) (c) the consumer price index (cpi) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. intuitively, the cpi represents the cost of living or the average price level. plot the cpi from 1960 to 2013.(d) the inflation rate is the yearly percentage change in the average price level. in practice, we usually use the percentage change in the cpi to compute the inflation rate. plot the inflation rate from 1960 to 2013.(e) explain the difference between the ex-ante and ex-post real interest rate. use the fisher equation to compute the ex-post real interest rate. plot the nominal interest rate and the ex-post real interest rate from 1960 to 2013 in the same graph.
