Instead of the rather inefficient barter system where , for example , a pig might be exchanged for three suits and a pair of shoes , in a monetary economy the values of all goods and services are monetised and transacted in a currency 在一个实行货币制度的经济体系里,我们不再以物易物,例如可能用一头猪来交换3套西装及一双皮鞋这种极之不便的制度,而是将所有货品与服务的价值或价格货币化,并以有关货币进行交易。
