The price of a brand-name laptop is $1,000 in 2018 and $1,100 in 2019. How could this price rise inject a bias into the CPI?     A. If students buy more generic laptops when brand-name laptops experience a rise in price but the BLS ignores this commodity substitution, then the CPI understates inflation.   B. If students buy their laptops online instead of in brick-and-mortar stores but the BLS ignores this outlet substitution, then the CPI understates inflation.
