PUMP PRIMING

The action taken to stimulate an economy, usually during a recessionary period, through government spending, and interest rate and tax reductions. The term "pump priming" is derived from the operation of older pumps; a suction valve had to be primed with water so that the pump would function properly. As with these pumps, pump priming assumes that the economy must be primed to function properly once again. In this regard, government spending is assumed to stimulate private spending, which in turn should lead to economic expansion.
