Abstract:

Public authorities [central and local] implement a specific fiscal and monetary policy of the state, they have to have a particular information base. Public authorities make short-term, medium-term and long-term decisions. The information base for taking decisions by the public authorities is provided by:

• natural measures
• statistical measures proposed by science
• monetary measures

Considering the need of making decisions in the global economy, statistical offices in the world agreed that the Gross Domestic  Product (GDP) will be such a measure.  GDP is used by governments, politicians, international organizations such as OECD, the World Bank, the International Monetary Fund, financial markets, UN agencies. In practice, we use GDP per capita and GDP real growth rate. Therefore, it is important to know factors affecting the GDP growth rate. It may be done through decomposition of a GDP growth rate which involves a final breakdown of the GDP into a domestic and foreign demand. This paper will evaluate the impact of components of a domestics and foreign demand for Poland over the years 2010-2019 in the quarterly view (39 observations – each observation comprises 6 variables, 234 variables in total).
