Recent studies analyse the dynamic of administered prices. However, the concept of administered
prices is not clearly defined in economic literature, and a common approach is missing. This
paper gives a brief description of the reasons for administered prices. Moreover, it focuses on the
difference between administered and regulated prices. Two relevant and unsolved cases are analysed:
telecommunication network industries and the rental market. A particular emphasis is addressed to
the regulatory frameworks within these sectors. It is investigated whether they do affect price behaviours.
In conclusion, the paper provides guidelines to identify the impact of the regulatory framework
on consumer price indices.
