When an increase in income is not associated with a change in the demand of a good.
The price elasticity of supply of Picasso paintings is zero, since no matter how high price rises, no more can ever be produced
No, the elasticity of demand can be positive, negative, or zero. It depends on how the quantity demanded changes in response to a change in price.
The price elasticity of supply is zero when the quantity supplied does not change in response to a change in price. This situation occurs in the case of perfectly inelastic supply, where producers are unable to alter their output regardless of price fluctuations. An example is a unique natural resource or a limited-edition artwork, where supply remains constant despite changes in demand or price.
A good with an income elasticity of demand less than zero is referred to as an "inferior good." This means that as consumer income increases, the demand for these goods decreases, as people tend to replace them with more desirable alternatives. Examples of inferior goods include budget brands or generic products.
The two extreme ranges of price elasticity of demand are Zero and Infinity.

i) "If the demand curve is vertical, elasticity is zero"Price Elasticity of Demand captures the shift in demand for rises in prices in percentage terms. Therefore if a commodity is such that no matter what price the producer charges the consumer has no alternative but to buy it, then for any price the demand for that commodity remains unaltered, maybe an example is a monopolist salt producer. Therefore the demand curve must be vertical, no matter what the price the quantity demanded is same, hence the price elasticity is zero.
Income elasticity of demand(EY):Income elasticity of demand measures the relationship between a change in quantity demanded and a change in income. Income elasticity of demand measures the degree responsiveness or reaction of the demand for a good to a change in the income of the consumer. It is calculated as the ratio of the percentage change in demand to the percentage change in income. In other words, it is defined as the rate of percentage change in quantity demanded resulted from percentage change in consumer's income. For example, if, in response to a 10% increase in income, the demand for a good increased by 20%, the income elasticity of demand would be 20%/10% = 2.Types of Income elasticity:i. Zero Income Elasticity of DemandZero income elasticity of demand is that in which quantity demand for a commodity remains constant to any change in income of the consumer. The value of the zero income elasticity is zero. It can be found in case of neutral goods. Graphically it can be explained asIn the graph, quantity demand is measured in X-axisand income is measured in Y-axis. DD is the demandcurve which is parallel to Y-axis implying that nochange in quantity demanded to any change inconsumer's income. Income is varying from Y1to Y2 and Y2 but quantity demand remain thesame quantity at Q1.ii. Positive Income Elasticity of Demand(EY>0)Positive income elasticity of demand is that in which increase in consumer's income leads to increase in quantity demanded and vice-versa. The numerical value of positive income elasticity is always greater than zero which may be greater than(for luxurious goods) or equal (for normal goods)or less than(for necessity goods) unity i.e. 1. For example, when consumers become reach or increase their income then they spend more on luxurious goods. On the contrary, consumers purchase less quantity of luxurious goods if their income decrease or they become poor. It can be further explained with the help of following figureIn the given figure, DD is the demand curve which is positivelyslopped. This demand curve implies, when consumers incomeincreases from Y1 to Y2 as in figure then consumer demandedmore quantity i.e. increases quantity from Q1 to Q2 accordingto figure.i. Negative Income Elasticity of Demand(EY
Price elasticity of demand= percentage change in demand/percentage cgange in price 2 = % chnge in demand/10 % change in demand= 2*10 % change in demand= 20%
its zero I'll do a bit of the explanation: Price Elasticity of Demand captures the shift in demand for rises in prices in percentage terms. Therefore if a commodity is such that no matter what price the producer charges the consumer has no alternative but to buy it, then for any price the demand for that commodity remains unaltered, maybe an example is a monopolist salt producer. Therefore the demand curve must be vertical, no matter what the price the quantity demanded is same, hence the price elasticity is zero. (dq/dp)(p/q) = 0, because (dq/dp) = 0
