Part 3 Answer the following questions by performing the appropriate calculations: 1. Jimmy is an avid candy connoisseur. Last year, he purchased 75 Snickers bars costing $2 each and 100 Butterfinger bars costing $1 each. This year, he purchased 120 Snickers bars for $1.50 each and 90 Butterfinger bars for $1.75 each. a. Assume that a typical consumer basket includes 50 bars of each type. Compute a consumer price index for each year and determine the percentage change in the index over the two years. b. Calculate Jimmy's nominal spending on candy bars in each year. Does nominal spending increase or decrease? c. Using the first year as the base year, determine Jimmy's real spending on candy bars in each year. Does real spending increase or decrease? d. Calculate the implicit price deflator (defined as nominal spending divided by real spending). How does this deflator compare the CPI calculated in part (a)? Which measurement do you think is more relevant in determining the change in Jimmy's cost of living? 2. In some country, the working-age population is 75,000. There were 10,000 discouraged workers and 8,000 unemployed labourers. What is the labour force of this country? a. Calculate the unemployment rate and the labour-force participation rate. b. Suppose that 2,000 of the unemployed workers decided to give up looking for work. Redo the calculations in part (a) and part (b). c. How did the unemployment rate change from part (b)? Using Okun's law, how would this change in unemployment change GDP? Do you think the prediction of Okun's law is realistic in the situation? 3. A farmer (at no cost) grows a bushel of soybean and sells it to a firm for $1.00. The firm turns the soybean into soysauce and sells it to a chef for $6.00. The chef uses the soysauce to make orange chicken and sells it to a professor for $ The professor eats the orange chicken. Compute: a. the value added by the farmer b. the value added by the firm 10

11 c. the value added by the chef d. the value added by the professor e. the GDP of this simple economy (assuming these are the only goods in the economy) f. Suppose the government imposes a value-added tax of 10% to be imposed on the value added amount at each stage. Compute the total tax revenue collected by the government. 11
