Change of assets account

The change in assets account emerged from macroeconomic theory . It contains the items " Household saving ", "Business saving " and " Business investment ". ${\displaystyle S_{H}\ }$ ${\displaystyle S_{U}\ }$ ${\displaystyle I\ }$

Due to the circular axiom , the sum of the savings is equal to the sum of the investments (without state participation). ${\displaystyle S=S_{H}+S_{U}=I\ }$

The change in wealth account is used in macroeconomic theory to represent certain changes in wealth (as the name suggests) through the circular model . Changes in assets based on changes in the value of liabilities and assets are not shown.

In the circular model with state participation, the asset change account also includes the items "State savings (SST)" and "State investments (IST)".
