The instruments that the government can use to deliver economic policy
There are remarkably few instruments available to the government to influence economic policy within a democracy. Beyond political persuasion, they are:
Tax system design;
Targeted tax yield;
Specific spending objectives;
Total government spending;
International capital controls;
The base level of interest;
Banking regulation, including on lending.
Each of these could be explained in greater detail but in essence they are all the weapons there are in the armoury.
Of microeconomics there is not a hint of a scintilla of an iota of understanding.
