Q.Give economic term:
More quantity is demanded due to changes in the factors determining demand other than price.

The economic term is Increase in demand — a rise in quantity demanded caused by favourable changes in non-price determinants, shown by a rightward shift of the demand curve. Answer: Increase in demand.

Why: It is important to separate two situations:

• A change in quantity demanded due to a change in the good's own price (other factors constant) is a movement along the demand curve (extension/contraction). …

The economic term is Decrease in demand — a fall in demand caused by unfavourable changes in factors other than the good's own price, shown by a leftward shift of the demand curve.

A change in the quantity demanded caused only by the good's own price is a movement along the curve (contraction when price rises). But when the good's own price stays constant and demand changes because of other determinants — such as a fall in income, a fall in the price of substitutes, or a change in tastes — the entire demand curve shifts:

| Change | Cause | Curve |

|---|---|---| …
