34. Within an AD-SRAS model, the simple multiplier can be measured by a. b. the extent of the horizontal shift of the AD curve in response to a change in autonomous expendiune the extent of the vertical shift of the AD curve in response to a change in autonomous expenditure the distance moved along the AD curve in response to a change in autonomous expenditure the distance between initial equilibrium and the new intersection of AD and SEAS in response to a change in autonomous expenditure the ratio of the change in price to the change in autonomous expenditure
