Statistical Indicators of Stock Assessed as a Percentage of GDP, and Consequences of Abusing the Logic of Statistical Thinking

The macroeconomic indicators concern both the flows that are not fully or partially compensated over a time interval, which can be cumulated or integrated, and the stocks or funds identified in a particular moment. These indicators are addressed either as free real and nominal indicators, or as bound or non-autonomous financial indicators. Statistical and economic problems are methodologically distinguished by the need for connection (free real indicators are updated through the time bound indicators, while free nominal macroeconomic indicators are characterized by a certain autonomy in relation to real free indicators), and also by turning flows into stocks and stocks into flows. This paper details three distinct solutions for the transformation of stocks to flow, solutions of different degrees of generalization: economic, statistical and physical, and all of which are detailed below using debt and budget examples.
