JiMi Boo correct. I'd say oblate spheriod too, which is also the shape of the earth because the earth is slightly flatter at the poles than a true sphere. Skittles are much flatter at the poles/face side.
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.
For this purpose, it raises the bank rates, sells securities in the open market, raises the reserve ratio, and adopts a number of selective credit control measures, such as raising margin requirements and regulating consumer credit. Monetary policy may not be effective in controlling inflation, if inflation is due to cost-push factors. Monetary policy can only be helpful in controlling inflation due to demand-pull factors. (b) Demonetisation of Currency: However, one of the monetary measures is to demonetise currency of higher denominations.
