1. Calculating inflation using a simple price index Consider an imaginary price index, the Undergraduate Price Index (UPI), created to represent the annual purchases made by a typical undergradute. The following table contains information on the market basket for the UPI and the price of each good in 2020, 2021, and 2022. The cost of each good in the basket as well as the basket's total cost are given for 2020. Perform these same calculations for 2021 and 2022, and enter the results in the following table Streaming services Iced coffees Textbooks Notebooks Energy drinks Total cost Price index Quantity in Basket 1 150 10 8 40 Suppose this price Index uses 2020 as the base year 2020 Price (Dollars) 64 2 80 2 3 Between 2020 and 2021, the UPI increased by Cost (Dollars) 64 300 800 16 120 1.300 100 Price (Dollars) 104 2 85 2 4 2021 In the last row of the cable, calculate and enter the value of the UPI for the remaining years Cost (Dollars) Price Cost (Dollars) (Dollars) 134 2 105 4 5 2022…

1. The index number representing the price level changes from 110 to 115 in 2019, and then from 115 to 120 in 2020. Since the index number increases by 5 this year, is five the inflation rate each year? Is the inflation rate the same each year?. NOTE: Explain and support the answer with calculations. 2. The total price of purchasing a basket of goods over four years is; year 1 - P940 year 2 - P970 year 3 - P1,000 year 4 - P1,070 Calculate two price indicates, one using year 1 as the base year (set equal to 100) and the other using the year 4 as the base year (set equal to 100). NOTE: Explain and support the answer with calculations.

2. Calculating and categorizing inflation This table indicates the historical level of the Consumer Price Index (CPI) for the United States for 1921, 1922, and 1923. Complete the table by (1) selecting the inflation rates for 1922 and 1923, and (2) indicating for each year whether there has been inflation, deflation, or hyperinflation. Year CPI Inflation Rate Change in Price Level 1921 17.9 — — 1922 16.8           1923 17.1             What rates of inflation for 1924 would be consistent with disinflation between 1923 and 1924? Check all that apply. 11.8%   1.7%   1.6%   51.8%     What rates of inflation for 1924 would be consistent with hyperinflation? Check all that apply. 120.0%   100.0%   15.0%   -1.8%

8. Inflation-induced tax distortions Shen receives a portion of his income from his holdings of interest-bearing U.S. government bonds. The bonds offer a real interest rate of 4% per year. The nominal interest rate on the bonds adjusts automatically to account for the inflation rate. The government taxes nominal interest income at a rate of 20%. The following table shows two scenarios: a low-inflation scenario and a high- inflation scenario. Given the real interest rate of 4% per year, find the nominal interest rate on Shen's bonds, the after-tax nominal interest rate, and the after-tax real interest rate under each inflation scenario. Inflation Rate Real Interest Rate Nominal Interest Rate After-Tax Nominal Interest Rate After-Tax Real Interest Rate (Percent) (Percent) (Percent) (Percent) (Percent) 1.5 4.0 8.0 4.0 Compared with higher inflation rates, a lower inflation rate will the after-tax real interest rate when the government taxes nominal interest income. This tends to Y saving,…
