Williams Optical Inc. is considering a new lean product cell. The present manufacturing approach produces a product in four separate steps. The production batch sizes are 69 units. The process time for each step is as follows: Process Step 1 6 minutes Process Step 2 8 minutes Process Step 3 5 minutes Process Step 4 4 minutes The time required to move each batch between steps is 18 minutes. In addition, the time to move raw materials to Process Step 1 is also 18 minutes, and the time to move completed units from Process Step 4 to finished goods inventory is 18 minutes. The new lean layout will allow the company to reduce the batch sizes from 69 units to 4 units. The time required to move each batch between steps and the inventory locations will be reduced to 3 minutes. The processing time in each step will stay the same. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the present and proposed production approaches. If required, round percentages to one decimal place. Present Approach Proposed Approach Value-added time 23 min min Non-value-added time min min Total lead time min min Value-added ratio (as a percent) % %

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.

(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.
