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.
US Inflation Rate Down To 2.4% In March. Consumer prices in the United States increased 2.4 percent year-on-year in March of 2017, lower than 2.7 percent in February and below market expectations of 2.6 percent. It is the lowest inflation rate in three months due to a slowdown in energy and services cost.
