Question
Consider a fictional price index, the College Student Price Index (CSPI), based on a typical college student’s annual purchases. Suppose the following table shows information on the market basket for the CSPI and the prices of each of the goods in 2017, 2018, and 2019.
The cost of each item in the basket and the total cost of the basket are shown for 2017.
Perform these same calculations for 2018 and 2019, and enter the results in the following table.

Part 1.
(I) Year 2018:
Cost of notebooks = 8 x 2 = 16
Cost of calculator = 1 x 104 = 104
Cost of large coffee = 150 x 2 = 300
Cost of energy drinks = 40 x 4 = 160
Cost of textbooks = 10 x 85 = 850
Total cost = 16 + 104 + 300 + 160 + 850 = 1,430
(II) Year 2019:
Cost of notebooks = 8 x 4 = 32
Cost of calculator = 1 x 134 = 134
Cost of large coffee = 150 x 2 = 300
Cost of energy drinks = 40 x 5 = 200
Cost of textbooks = 10 x 105 = 1,050
Total cost = 32 + 134 + 300 + 200 + 1,050 = 1,716

He that can earn Ten Shillings a Day by his Labour, and goes abroad, or sits idle one half of that Day, tho' he spends but Sixpence during his Diversion or Idleness, ought not to reckon That the only Expence; he has really spent or rather thrown away besides."

Assume the price of housing rises by 4%, the price of education falls by 10%, and prices remain constant for all other goods. Based on the information given, we can definitely say Select one: a.because the price of education fell by more than the price of housing rose, the consumer price index (CPI) must have decreased. b.the CPI is higher than in the previous year. c.if consumers get a 4% pay raise, they are worse off in terms of their real income compared to inflation as measured the CPI. d.because housing is a luxury (as is education), consumers are certainly no worse off in terms of their real wages as measured by the CPI. e.the CPI is unchanged from the previous year.arrow_forwardExplain the impact of higher corn prices on consumers.
