I agree such a study could be interesting, although anecdotally I presume (ignoring inflation) there are more shifts in expenditures vs flat out increases. Ten years ago, someone paying for a landline, cable subscription, and iTunes song downloads is probably paying for a mobile plan, one or more video streaming services, and probably one music streaming service. Presumably the gig economy has also caused shifts. I track all my expenses. Last year, I paid ~$9,200 over the course of the year for my auto payment, auto insurance, and parking fees alone, not counting gasoline or maintenance. This year, I’ve spent < $600 on transportation because I now only walk or use Uber and Lyft. Remember though - at least in the US, outside of the large cities, there’s still that population that lives in small towns. I have family in Kansas, Oklahoma, and Tennessee. For people in those specific towns, you don’t see Uber very much because everyone has a vehicle. There is no 1 hour Prime Now delivery. The gig economy is less impactful than a place such as Seattle or San Diego.
