Table 10.7 provides some hypothetical data on macroeconomic accounts for three
countries represented by A, B, and C and measured in billions of currency
units. In Table \(10.7,\) private household saving is \(\mathrm{SH}\), tax revenue
is \(\mathrm{T},\) government spending is \(\mathrm{G},\) and investment spending
is I.
$$\begin{array}{l|l|l|l}\hline {} & {\text { A }} & {\text { B }} & {\text { C
}} \\\\\hline \text { SH } & 700 & 500 & 600 \\\\\hline \text { T } & 00 & 500
& 500 \\\\\hline \text { G } & 600 & 350 & 650 \\\\\hline \text { I } & 800 &
400 & 450 \\\\\hline\end{array}$$
a. Calculate the trade balance and the net inflow of foreign saving for each
country.
b. State whether each one has a trade surplus or deficit (or balanced trade).
c. State whether each is a net lender or borrower internationally and explain.
