What are the types of income elasticity of demand?
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
What do we call a good whose income elasticity is less than zero?
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.
Is the elasticity of demand always negative?
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.
Is it always true When demand elasticity is equal to -1 marginal revenue is equal to 0?
Yes, when demand elasticity is equal to -1 (unitary elasticity), marginal revenue is indeed equal to 0. This occurs because, at this point, any change in quantity sold does not affect total revenue; increases or decreases in quantity will offset price changes, resulting in no net change in revenue. Thus, when elasticity is -1, the firm maximizes total revenue, leading to marginal revenue being zero.
Is a vertical demand elastic?
A vertical demand curve represents perfectly inelastic demand, meaning that the quantity demanded does not change regardless of price changes. Consumers will purchase the same amount of the good, regardless of its price, indicating that they have no substitutes or alternatives. In this case, the price elasticity of demand is equal to zero.

What are the 2 extreme situations of price elasticity of demand?
The two extreme ranges of price elasticity of demand are Zero and Infinity.
Is the elasticity of demand always negative?
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.

What do you call a good whose income elasticity is less than zero?
Sticky Goods
When a firm's marginal revenue is zero what can be said about the elasticity of demand for the output of the firm A. Demand is inelastic. B. Demand is elastic. C. Demand is unit elastic.?
Demand is unit elastic.
Is a vertical demand elastic?
A vertical demand curve represents perfectly inelastic demand, meaning that the quantity demanded does not change regardless of price changes. Consumers will purchase the same amount of the good, regardless of its price, indicating that they have no substitutes or alternatives. In this case, the price elasticity of demand is equal to zero.
When a price of a good increased by 2 percent the quantity demanded decreased by 10 percent What is the price elasticity of demand?
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%
If the value of the cross price elasticity of demand between two goods is approximately zero they are considered?

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.
What is demand when the coefficient of price elasticity of demand is zero?
When the coefficient of price elasticity of demand is zero, it indicates that demand is perfectly inelastic. This means that consumers will purchase the same quantity of a good or service regardless of any changes in its price. In such cases, the quantity demanded remains constant, as the good is considered a necessity with no close substitutes. Examples of perfectly inelastic demand often include essential medications or life-saving products.
