Thanks for your reply. There is still a point unclear to me. As far as I know Net private savings should be equal to S - I that is the remaining savings after deducting investment while in the equation you define it as S + I - C. Could you clarify this point?

Given they have grouped private investments and savings together I interpreted investments as say buying bonds or a long term deposit which is another form of saving essentially!

This would imply that you define net private savings as (S + I) - C wirh (S+ I) some sort of "broad" definition of savings (savings + bonds and long term deposit) while in the literature i've found a different definition, that is net privare savings = S - I with no reference to consumption. Still, what is the right definition of net private savings?

<p>I have found the following equations:</p>
<p>Exports - Imports = Private Consumption - Private investments and savings + Taxes - Government Expenses = Net private savings + Net public deficit.</p>
<p>While I could understand the equation:</p>
<p>Exports - Imports = Net private savings + Net public deficit</p>
<p>I don't understand how the first equality sign could hold.
Could someone explain it?

# Net exports equation

(Asked by: username_0 on 2024-07-30)

I have found the following equations:

Exports - Imports = Private Consumption - Private investments and savings + Taxes - Government Expenses = Net private savings + Net public deficit.

While I could understand the equation:

Exports - Imports = Net private savings + Net public deficit

I don't understand how the first equality sign could hold.
Could someone explain it?
Many thanks in advance

The two equations are essentially identical, **but I believe two of the terms are around the wrong way**.

The expression after the first equality is trying to break net private savings and the net public deficit into its constituent parts.

Net private savings should be = *private investment and savings* - *private consumption*

Net public deficit is = *Taxes* - *Government Expenses*

In the top equation, *Private Consumption* and *Private investments and savings* need to be swapped around. Then the equality should hold.

Noting that net public deficit is negative if there is a deficit and positive if there is a surplus.
