1. UNECE Workshop on Consumer Price Indices Session 8: OOH-Turkish Experiences Presentation by Cengiz Erdoğan, TurkStat October 10-13 Istanbul, Turkey

2. OOH-Turkish Experiences A durable good is therefore defined as one which may be used repeatedly or continuously over a period of more than a year, assuming a normal or average rate of physical usage. A consumer durable is a good that may be used for purposes of consumption repeatedly or continuously over a period of a year or more.

3. OOH-Turkish Experiences There are 3 main methods for dealing with the durability problem:  Ignore the problem of distributing the initial cost of the durable over the useful life of the good and allocate the entire charge to the period of purchase. This is known as the acquisitions approach and it is the present approach used by Consumer Price Index statisticians for all durables with the exception of housing.

4. OOH-Turkish Experiences  The rental equivalence or leasing equivalence approach. In this approach, a period price is imputed for the durable which is equal to the rental price or leasing price of an equivalent consumer durable for the same period of time.  The user cost approach. In this approach, the initial purchase cost of the durable is decomposed into two parts: one part which reflects an estimated cost of using the services of the durable for the period and another part, which is regarded as an investment, which must earn some exogenous rate of return.

5. OOH-Turkish Experiences The net acquisition approach is the change in the price of newly purchased owner occupied dwellings, weighted by the net purchases of the reference population. This is an asset based measure, and therefore comes close to (preferred) measure of inflation as a change in the value of money, though the change in the price of the stock of existing houses rather than just of net purchases would in some respects be even better. It is, moreover, consistent with the treatment of other durables.

7. Turkey has an experience of rental equivalence approach. This approach is used in 1994 Based CPI. In the 1994 Based CPI, the rate of OOH was % 77,1 while the rented houses rate was %22,9. In the field work, data collectors were trying to find rented houses which have the similar specifications with Owner’s houses in that area Currently, OOH cost is not covered

8. Main Difficulties in OOH-Turkish Experiences Turkey has big rural areas where people have their own houses. The main difficulty is to find rented houses to impute OOH. The weight given to rent (actual rent + imputed) is bigger than the actual rent payment.
