    效率工资(Efficiency wage)


    答案:
    解析:
    效率工资理论既是一个微观经济学考点,也是一个宏观经济学考点。当劳动市场面临信息不对称时,雇主可给员工支付高于均衡工资的工资水平来解决彼此存在的信息不对称。另外,效率工资理论被新凯恩斯学派用来解释工资黏性和失业的存在。

    经济学中,效率工资是指雇主为了提高工人生产率而主动支付给雇员的高于市场均衡水平的工资。效率工资理论的基本观点认为,雇主必须把工资作为刺激雇员努力工作的手段。雇员在工作时候的努力程度决定了生产和经营的经济效率,如果员工积极性高,则生产的效率就高,反之亦然;而雇员工作时的努力程度又在很大程度上取决于雇员得到的报酬的高低。如果雇主给雇员支付的工资高于其他企业从事同种工作的雇员的工资水平,雇员就会认为自己的工作是有前途的“好工作”,并为了保持这份好工作而努力工作,这就有利于企业效率的提高。 根据效率工资理论,经济学家们得出结论,雇主除非迫不得已否则不愿意降低员工的工资,因为这不利于刺激工人的生产积极性。不但如此,社会上的工资水平总体上有不断上升的趋势。而且,高工资率还可以刺激产生高效率,效率的提高不可避免地引起对劳动的需求的下降,从而社会上失业的存在就是可以理解的。
