(1)比较说明传统货币数量说和现代货币数量说的核心内容。
(2)根据凯恩斯学派的观点，货币需求函数为：L(Y，r)=L₁(Y)+L₂(r)=kY+hr，
其中，y为国内生产总值，r为实际利率。
①请问L₁和L₂分别表示何种需求
②以M表示货币供给，设货币需求函数的具体表达式为：L(Y，r)=0.4y-8 000r。当y=1 000亿元，r=2%时，货币供求达到平衡。如果Y提高1%而货币供给不变，请问r要提高几个基本点(BIP)，才能维持货币的供求平衡

Questions from 36 to 40 are based on the following passage:Against this background, the WTO faces several daunting challenges. The first is to continue bringing down tariffs on traded goods. Average penalties have fallen steadily since the GATT’s formation but even the most open economies retain lofty barriers: for instance, America still charges a tariff of 14.6% on import of clothing,five times higher than its average levy.Resistance to tariff cuts is pest in agriculture. According to Tim Josling,a trade expert at Stanford University, tariffs and other barriers on farm goodsaverage a crippling 40% worldwide and create distortions that “destroy huge amounts of value”. A new set of global farm talks is planned to start in 1999. At the least,you might think, these could lock in impressive reforms in Latin America and encourage further watering-down of the European Union’s Common Agricultural Policy.But they will prove difficult: squabbles over agriculture almost sank the Uruguay round.
