Problemy konstrukcji syntetycznego wskaźnika dla gospodarki polskiej
Problems Involved in the Development of the Synthetic Business Indicator for the Polish Economy
Languages of publication
This is a concise review of the major methodolical problems related to development of the general indicator of business activity for the Polish economy based on the RIED survey data. The first part of the paper presents the basic assumption underlying the constructionof the RIED's general indicator as well as the formula used in calculating it. In the early stage the synthetic indicator has been compiled from the qualitative data rendered by three surveys covering industry, agriculture and households. By the end of 1993 the formula was extended to include two new surveys launched in construction and trade. The second part discusses the following methodological problems faced in the development of the synthetic indicator for the whole economy: (a) comparison of the two versions of the indicator differing in the input data for industry, (b) comparison of the original and the extended version of the indicator, (c) the concepts of variable weights that could replace the constant weight system now used in complining the synthetic indicator.
