Future actions:
Facilitate the analysis of the selected services at constant prices:
It is necessary to previously explore and study the different alternatives for the construction of deflators for the Sales indices at current prices.

14. CHILE : Index of Sales of Selected Services
Construction of deflators for the selected services is difficult to approach, in part, because one of the requirements to construct a price index is the identification of products which are homogeneous, permanent in the market and with prices easy to collect. The heterogeneous nature of prices of these activities introduce a complexity sometimes difficult to solve.
Deflators or price indices of services that reflect the changes of their levels of prices are not currently available.

15. CHILE : Index of Sales of Selected Services
Prices of Services related to intermediate consumption are non-existent. Only prices of final consumption derived from the ICP are available; they could be partially used as input of the price indexes of services.
A direct solution could be to use ICP as deflator for all services.
