Note:  CPI,  and  thus  inflaNon,  depend  on  the  calculaNon  method  used:  

The  table  (start  of  the  lecture)  is  from  Stats  Canada;  CPI  is  calculated  as  average  over  12  months  in  the  calendar  year  

The  inflaNon  calculator  from  Bank  of  Canada  compares  CPIs  from  January/February  of  one  year  to  January/February  of  another

PPP  =  Purchasing  Power  Parity    

CPI  =  price  changes  over  Nme,  PPP  =  price  changes  across  countries  

Compare  salaries  in  Japan  and  Canada  (expressed  in  a  common  currency,  called  InternaNonal  Dollar):  

Example:  salaries            Japan  ...  $  150,000          Canada  ...  $120,000  

Who  makes  more?

Example:  1  kg  of  bananas  (again,  InternaNonal  $)  

     in  Canada  ...  $  0.79        in  Austria  ...  $  0.87  

what  is  $100  in  Canada  equivalent  to  in  Austria,  i.e.,  how  much  do  we  have  to  pay  in  Austria  for  a  thing  that  costs  $100  in  Canada?

Avocado  toast  index  …

The  35-­‐year-­‐old  property  developer  told  the  Australian  ediNon  of  60  Minutes  that  when  he  was  saving  for  his  first  home,  he  “wasn't  buying  smashed  avocado  for  $19  and  four  coffees  at  $4  each”

Dow30  (former  Dow  Jones  Industrial  Average)
