Discredited and inaccurate.......yet it continues to be used for setting regulated fares, and by companies increasing my bills each year.
Its a bit chicken and egg. Personally, I think faes should be linked to CPI, and wages similarly.
Having personally studied the differences between RPI and CPI, my official (and exclusive to this forum) opinion is that RPI is s**te.
The last period of high inflation was not caused by wages rising. It was caused by a combination of Ukraine, fuel prices and food prices increasing, and the government largesse of the Covid years pumping money into the economy. That is AIUI the general consensus - are there any respected economists/economic publications you can cite who disagree with that?
Entirely correct. Also, food orices rose largely because fuel (energy) prices rose.
What is also correct is that fuel prices are now almost exactly the same in cash terms as they were in 2019, yet CPI index is 25% higher than 1/1/19.
What happens (in very, very broad terms) is that with a price ‘shock’ of fuel, inflation rises, therefore pay rises, but when fuel drops back pay doesn‘t.
