Is water an inferior good?

What are the determinants of income elasticity of demand?

The four factors that affect price elasticity of demand are (1) availability of substitutes, (2) if the good is a luxury or a necessity, (3) the proportion of income spent on the good, and (4) how much time has elapsed since the time the price changed. If income elasticity is positive, the good is normal.

What is an inferior good example?

These are two categories that are opposites of one another so it is completely impossible to be both at once. … That is, when the consumers’ incomes rise, demand for these goods falls and when consumers’ incomes fall, demand for these goods rises.

Is 0.5 elastic or inelastic?

On the other hand, if the quantity bought increases by 25% and the price decreases by 50%, the price elasticity is (25%) / (-50%) = -0.5. Price elasticity of demand is usually a negative figure, as this shows that as demand goes up, the price goes down. And as demand goes down, the price goes up.
