所谓货币流通速度V是指实际GNP与实际货币持有量的比率,V=Y/(M/P)。请利用等式(14-4)推导货币流通速度的表达
所谓货币流通速度V是指实际GNP与实际货币持有量的比率,V=Y/(M/P)。请利用等式(14-4)推导货币流通速度的表达式,并解释货币流通速度是如何随R和Y的变化而变动的。(提示:产出变化对v的影响取决于相对于实际产出的货币总需求弹性,经济学家认为该弹性小于1。)货币流通速度与汇率之间存在什么联系?
The velocity of money,V,is defined as the ratio of real GNP to real money holdings,V=Y/(M/P)in this chapter's notation.Use equation(14-4)to derive an expression for velocity and explain how velocity varies with changes in R and in Y.(Hint:The effect of output changes on V depends on the elasticity of aggregate money demand with respect to real output,which economists believe to be less than unity.)What is the relationship between velocity and the exchange rate?
