The term „liquidity trap" was suggested by Keynes (1936) as a situation in which monetary policy is unable to stimulate an economy through increasing money supply or lowering interest rates. Liquidity traps typically occur when deflation is expected.

will fail to provide a stimulative effect to the economy............
