Look again at Solved Problem \(29.3,\) where the saving and investment equation
\(S=I+N X\) is derived. In deriving this equation, we assumed that national
income was equal to \(Y\). But \(Y\) only includes income earned by households. In
the modern U.S. economy, households receive substantial transfer payments-such
as Social Security payments and unemployment insurance paymentsfrom the
government. Suppose that we define national income as being equal to \(Y+T R,\)
where \(T R\) equals government transfer payments, and we also define government
spending as being equal to \(G+T R\). Show that after making these adjustments,
we end up with the same saving and investment equation.
