• The subject of economics (VWL) is an economic activity in an economy as well as its international ties with other economies with regard to the movement of goods and money. 
  • Interactions between the decision-makers involved (state, private households, companies) are examined and explained. Economics, therefore, examines fundamental economic relationships and regularities in a society, both in terms of individual economic and macroeconomic units (microeconomics and macroeconomics).
