A helix (pl: helixes or helices) is a type of smooth space curve, i.e. a curve in three-dimensional space. It has the property that the tangent line at any point makes a constant angle with a fixed line called the axis. Examples of helices are coil springs and the handrails of spiral staircases.
What is a 'Tight Monetary Policy'. Tight monetary policy is a course of action undertaken by the Federal Reserve to constrict spending in an economy that is seen to be growing too quickly or to curb inflation when it is rising too fast.
Monetary policy is the control of money supply by the central bank (so in Britain it is the Bank of England and in the US it's the Federal Reserve). Inflation can be caused because aggregate demand exceeds aggregate supply therefore by reducing consumer spending and investment it can alleviate inflation.
