Volume 1: Consumer Price Indices

Cyprus

Official title

Consumer Price Index.

Scope

The index is computed monthly and covers all private households in urban and rural areas.

Official base

1992 = 100.

Source of weights

The weights and selected items were derived from a household expenditure survey conducted during the period December 1990 - November 1991 covering a random sample of households residing in the Government Controlled Area. Urban and rural households of all classes irrespective of income were represented in the survey. All 3.400 households constituting 1,7 percent of total households were enumerated, 2.261 in urban and 1.139 in rural areas. Households of foreign diplomats and people living in institutions such as hospitals, old aged homes etc. were excluded from the sample. The time lag between survey period and the base period was not considered important and the weights have not been adjusted in any way.

Household consumption expenditure

The consumption expenditure used for deriving the weights corresponds to the SNA classification of household final consumption expenditure with the following amendments: (a) expenditure on lottery, gambling, horse race betting etc. was not included for the calculation of the weights, and (b) expenditure on motor vehicle circulation licences and driving licences was included for the calculation of weights.

Goods from own production were valued at wholesale prices and included in expenditure. For own-dwelling occupiers, an imputed rent was estimated and used in calculating the weights. Durable goods credit purchases were considered as normal purchases and the full price of the items was taken into account.

Second-hand purchases were also taken into account at the price bought. Trade-in of used goods and in part payment for new ones were only considered in the case of cars for which only the net difference between the used car and the new purchase was used in calculating expenditure on cars.

Contributions to social insurance and pension funds were excluded from the expenditure used for derivating the weights. Insurance associated with specific consumer goods was included. Expenditure on health care was included only if paid directly by a member of the household. Income taxes and other direct taxes, life insurance payments and other transfers of money to other households were also excluded. However, purchases of gifts given to other households were included. :SAMP. The criteria for selecting an item for price collection were: its availability on the retail market, its share in total expenditure and quality, unit of measurement, variety and other specifications being available. The weights of items not priced were distributed proportionately among similar items that are priced.

As no point-of-purchase survey was carried out, the outlets where price data are obtained were selected empirically so as to include a representative sample of stores from which the index population make their purchases. The outlets selected were restricted to the three largest towns, namely Nicosia, Limassol and Larnaca. :meth. Prices for each type of item are obtained from two outlets in each town by trained enumerators from the Department of Statistics and Research.

The price collection frequency varies according to the item. Prices for fresh fruit and vegetables are collected once a week (every Thursday) from the municipal market, while for other commodities prices are obtained once a month (on the Thursday closest to the 15th of the month). For price controlled items (such as fuel, electricity, telephone, water etc.) data are obtained from invoices issued by the organisations concerned.

The prices refer to actual prices paid, thus discounts and sales are taken into account. Second hand purchases are not priced. Black market prices and credit terms are not taken into consideration. Import prices are reflected in the respective retail prices. Trade in of used goods for part payment for a new item is disregarded, only the new item is priced.

Housing

Rent quotations are obtained monthly from 300 dwellings, through mail questionnaires and by personal visits for those not replying by post. The sample of 300 dwellings covered by the rent data was randomly selected from Nicosia (148), Limassol (102) and Larnaca (50). The number of dwellings selected in each town was based on the population distribution. The sample selection was restricted to urban dwellings with a monthly rent of 35 - 200 Cyprus pounds as determined in the household expenditure survey. This group represented 88 per cent of all rented urban dwellings.

The rent index is computed as follows: first, the current rent per dwelling for each town is divided by the coresponding average rent at the base period (1992=100). Then the sum of the price relatives is divided by the number of dwellings in each town. These are then averaged for the 3 towns using the same weights as for all other items in the Indes (i.e. Nicosia 5, Limassol 3, Larnaca 2).

Owner-occupied houses were taken into account in calculating the overall rent weight by estimating an imputed rent. In computing the rent index, only the rents actually paid are taken into account; the imputed rents are disregarded on the assumption that their evolution is similar to that of rent actually paid.

Specification of varieties

The specification of items to be prices are given in terms of brand, make, size, unit and quality. These specifications are not systematically predetermined but are based on what is available in the retail market.

Substitution, quality change, etc.

If quality changes take place, the relevant items are substituted for so that the price relative remains unchanged. New products are only introduced when a revision of the weights takes place, about once every five years. The disappearance of a given quality from the market is dealt with by substituting another similar product available on the market and the price relative is left unchanged. If the quality of the substitute product is not directly comparable with that of the previous product, an adjustment for quality is made.

A substitution is made by linking the prices of the new and old items, by taking a theoretical base price for the substitute item. For this, it is necessary to obtain prices for both the current and previous months.

Seasonal items

Last recorded price of the seasonal items such as heaters, summer and winter clothing and footwear, flowers etc, is repeated in the months these items are not available. For fruit and vegetable indices, the total weights are kept constant each month but the variety of items and respective weights vary from month to month, depending on their availability.

Computation

The index is computed according to the Laspeyres formula as a weighted arithmetic average with fixed base, using weights corresponding to the base period.

The index is directly computed at the national level. A weighted average price is computed for the three towns using weights, Nicosia 5, Limassol 3 and Larnaca 2, which approximately reflect their respective populations. The price relative is calculated by dividing the average price of the current period by the average price of the preceding period.
