When the money market is drawn with the value of money on the vertical axis, an increase in the price level causes a

a. shift to the right of the money demand curve.
b. shift to the left of the money demand curve.
c. movement to the left along the money demand curve.
d. movement to the right along the money demand curve.

Answer is D, but why? What's the difference between a shift versus a movement? What concepts need to be understood in order to arrive at this answer? Please explain.

Answer:-

According to the above question when the money market is drawn with the value of money on the vertical axis, an increase in the price level causes a movement to the right along the demand curve because movement along the demand curve will occur when the price of the good changes and the quantity demanded changes with accordance to the original and exact demand relationship and it is to the right because there is an increase in the level of price which will definitely cause a movement to the right side of the demand curve, if there would be a decrease in the price then the movement to the left along the demand curve could happen, but in the given question there is increase in the price.

It could be better understood with a curve:-

Difference between a Shift versus a Movement are:-

SHIFT:-

  • A shift in the demand curve changes when a good's quantity demanded changes even though the price remains constant and same.
  • There is a change in quantity demanded due to some other factors causing the curve to shift to a particular side.
  • Price is non-determinant.
  • It indicates a change in demand.
  • Demand curve will shift rightwards of leftwards.

Movement:-

  • A Movement in demand curve is when the commodity faces both change in price and quantity demanded, causing a curve to move in specific direction.
  • There is a change along the curve.
  • The determinant is price.
  • There is a change in quantity demanded.
  • The Demand curve will move upward or downward.

Curve of A Shift in Demand Curve-

Curve Of Movement along the Demand Curve-

That's all to understand about a shift and movement along the demand curve.
