Final answer:
The national saving and investment identity is the identity that shows the value of net exports equal to net capital outflow.
Step-by-step explanation:
The identity that shows the value of net exports equal to net capital outflow is called the national saving and investment identity. This identity is based on the relationship that the total quantity of financial capital supplied from all sources must equal the total quantity of financial capital demanded from all sources. In other words, the amount of money flowing into a country through exports should be equal to the amount of money leaving the country through investments.
