The work on experimental statistics involves research on the implementation of the KLEMS productivity accounts in Poland. The decomposition of economic growth in the KLEMS accounts for Poland was done in the form of gross value added decomposition. The KLEMS accounts provide the basic macroeconomic information by PKD 2007 (NACE 2) groupings on the economy, and they are an important tool helping the economic growth researcher. The economic growth decomposition allows to determine its sources, and therefore indirectly interpret its causes. It can form a basis for numerous analyses and studies of economic growth and for international comparisons with other countries performing these accounts. The publication includes: KLEMS accounts methodology for the Polish economy and KLEMS tables for the Polish economy.
