PROBLEM SET $4$

Data

$\backslash$table$[[$DI$,$C$,$S$,$I,C $+$ I,G$,$C$+$I$+$G$,$XN$,$TE$],[0,50,0,50,,50,,50,],[100,100,50,50,,50,,50,],[200,150,,50,,50,,50,],[300,200,,50,,50,,50,],[400,250,,50,,50,,50,],[500,300,,50,,50,,50,]]$

DI $-$ disposable income, C $-$ Consumption, S $-$ Savings, I $-$ Investment, G $-$ Government Expenditure, $xN-$ Net exports, and TE $-$ Total Equilibrium. Please note that TE is also referred to as GDP or Income. So TE or Y $=$ C $+$ I $+$ G $+$ XN$.$ Therefore if Disposable income $($DI$)$ is $$0$ and consumption, $($C$)$ is $$50,$ how much is your saving $($S$)$

Calculate $S-C_{+}I{C}_{+}I+G,C_{+}I+G+xN$ for each level of disposable income.

Calculate equilibrium using all sectors $($TE$).$

What would the new equilibrium be if $"$ I $"$ was increased to $100$ instead of $50?...$ What would this mean to the economy?PPP
