What is the relationship between GDP and CPI(consumer price index)? My thinking is that if the CPI increases, this means that the market basket cost has increased, therefore, the consumer spending has increased. If the consumer spending increases, then GDP increases. However, depending on the consumer preferences, CPI can either underestimate or overestimate the cost of living. So from here, I cannot draw consequences about how CPI affects GDP or vice versa. Can someone please explain this? Is my thinking correct? Can there be any additions to these?

Any help would be appreciated!

Thanks in advance!
