What are the macroexonomic effects of reducing budget deficit? Some evaluations also?
The budget deficit refers to the government spending (for example on the nhs) more than they are receiving in revenue (taxation). These are the components of Fiscal Policy.
The CURRENT ACCOUNT deficit is referring to your exports-imports = net exports.
So to reduce the budget deficit you would decrease government spending and increase taxation. However by doing this it also means that economic growth is reduced and unemployment is increased- as government spending is a component of AD and a injection into National Income whilst taxation is a withdrawal.
Evaluation would include: the size in the change in spending/taxation, other factors eg interest rates, the government objectives eg if they are trying to achieve sustained economic growth then they wouldnt necessarily attempt to reduce the budget deficit but focus on this instead
