to all those people saying tht its puble expenditure then why did the question say
gross investment??? shouldnt it include the public expenditure also>/
atleast part of it.
and in real life u cant have NO exports thats not very convincing .
It doesnt need to be, Examiner *censored* was just testing our theoretical knowledge, weather we knew what closed economy is, I didnt even read the question, about the person who is willing to pay back the debt, It is higher salary, If the price of the goods increase, say chocolates or chips, (because it never said anything about ESSENTIAL goods, we take it as general price increase), he will spend less, the only logical answer is Higher salary, as more money means he has more disposable income to spend.
