Ana and Shen need to decide which one of them will need to take time off work to complete the rather urgent task of shearing their llamas. Ana is pretty good with a pair of shears; she can shear the llamas in one hour. Shen is somewhat slow; it takes him six hours to shear the llamas. Ana earns $120 per hour as a business consultant, while Shen earns $15 per hour as a lifeguard. Keeping in mind that either Ana or Shen must take time off work to shear the llamas, who has the lowest opportunity cost of completing the task?
A. Ana

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.
