关于总需求曲线斜率问题的进一步探讨

Study of the Slope of the Aggregate Demand Curve

总需求曲线的斜率反映的是价格水平的变动对均衡支出的影响,斜率的大小决定了宏观经济政策效果的大小。基于数学推导、图形分析以及理论推导三个维度分别探讨了IS曲线斜率、LM曲线斜率对总需求曲线斜率的影响。研究结论认为:第一,h、k与AD曲线斜率呈正相关,d、β与AD曲线斜率呈负相关;第二,IS曲线斜率与AD曲线斜率呈正相关;第三,在一定条件下LM曲线斜率与AD曲线斜率呈负相关。

The slope of the aggregate demand curve reflects the changes in the price level of expenditure affects the equilibrium slope, which determines the effect of macro - economic policy size. Based on the mathematical derivation, the three dimensions of graphical analysis , we tried to study the IS effect of LM curve slope, slope of the curve on the slope of aggregate demand curve. It is concluded that the relation between h, k and the slope of the AD curve is positive correlation. IS curve and the slope of the AD curve was positively negative correlation. Under certain conditions, the relation between the slope of LM curve and the slope of the AD curve was negative.
