investment are not available from Central Statistical Office (GUS). However, quarterly

estimates of economic activities are available from some economic institutes.

GDP is disaggregated into five institutional sectors (enterprises, financial

institutions, governments, households and non commercial institutions) and into 15 main

economic sectors. The sectors are disaggregated according to the European Economic

Classification (EKD), which was introduced in 1994. This is a major reason why time series

analyses are either difficult or impossible to conduct.  Since quarterly data are not

generally available, and the number of years available in a consistent time series is so low,

time series regression analysis would be difficult or impossible.  Nevertheless, the current

system of National Accounts of the Polish economy is operated according to United

Nations standards and further progress is expected; for instance, the Central Statistical

Office (CSO) is expected to publish quarterly estimates of GDP, and its aggregates.

Demand Data and Price Indexes

Domestic demand aggregates are also regularly published by GUS in the Statistical

Yearbook. Domestic demand consists of: private consumption, public consumption, and

investment (including changes of inventories). These aggregates are available by

institutional sectors (as described above). Moreover, data on foreign demand (that is, data

on exports and imports) are published, which balance the total GDP.

Nominal and real personal income are published and are disaggregated to several

categories: salaries, social benefits and other transfers, and income from property.

Data

on the disposable income of households are available according to type of household.

Disposal income consists of savings and individual consumption; the last item is

disaggregated to five main expense groups: food, alcohol, non food articles, services and

depreciation (amortization) of dwellings (housing). The last item is defined as estimated

amortization of co operative houses and private houses (so it covers only these parts of

the housing stock). Public consumption includes, among other items, subsidies to housing,

mostly to cover the maintenance costs of the communal housing stock.

Time series analyses require price indexes. All the main price indexes are regularly

published, including the investment price index, production price index, and consumer

price index, as well as the GDP index.  PPI and CPI are calculated according to Laspeyer s

formula.  Most of the indexes are calculated on the basis of monthly surveys and are

available on a monthly basis.
