In equilibrium, injections are equal to withdrawals.
Injections refer to the money that flows into an economy, which includes investments, government spending, and exports. Withdrawals, on the other hand, refer to the money that flows out of an economy, which includes savings, taxes, and imports.
When injections are equal to withdrawals, it means that the money flowing into the economy is equal to the money flowing out of the economy. This is known as the equilibrium state, and it is an important concept in macroeconomics.
For example, if an economy is experiencing a surge in exports, this will increase the injections into the economy. However, if there is also a corresponding increase in imports, which is a withdrawal, the injections and withdrawals will balance each other out, and the economy will remain in equilibrium.
To put it simply, in economics, injections refer to the money flowing into an economy, and withdrawals refer to the money flowing out of an economy. In equilibrium, these two must be equal, meaning that the money flowing in is equal to the money flowing out.
