I have a dataset of yearly gross investment since 1970 in chained 2010-prices or "Fisher index prices". I want to depreciate each year's investment and add them up, however, reading about Fisher capital it is clear that it cannot simply be added when you have several different components, e.g. investments AND private consumption. Is it ok to add together chained prices over a time period from the same component, i.e. gross investment from 1970 to 2020, and will I get my answer in chained 2010-dollars?
