They both will increase (or decrease).
Inferior goodA good for which an INCREASE(decrease) in consumer income will lead to a DECREASE(increase) in demand for that good.Normal GoodA good for which an INCREASE(decrease) in consumer income will lead to a INCREASE(decrease) in demand for that good.
Income effect
If consumer income increases, demand will increase. If income decreases, there is less money to spend, so demand for products that are not necessary will decrease. Consumer tastes influence what products are in demand. This can change over time, so a product that is in high demand may become a low demand product and visa versa.
Income effect-change in the amount that consumers will buy because their income changed.substitution effect-change in the amount that consumers will buy because they purchase goods instead.substitution effect the change in demand for a good when the relative price between a good and its substitute changes. income effect the change in demand for a good when the income of the consumer change.
chnage in consumer's equilbrium due to change in income of the consumer..known as income effect.

An increase in income tends to shift the demand curve for a good or service:For a normal good, the curve will shift to the right, indicating an increase in the demand at the same price.For an inferior good, the curve will tend to shift to the left, indicating a decrease in demand at the same price.
Demand shifters include consumer income, number of consumer (population), consumer taste and preferences, and expectations: future prices of complements and substitutes and future income.
A good that decreases in demand when consumer income rises; having a negative Income increases will thus affect the consumption of these goods.
decompose total effect of price increase for an inferior good and giffen into substitution and income effect, in each case derive both the ordinary and compensated demand curve
When an increase in income is not associated with a change in the demand of a good.
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
A psychological phenomenon whereby people do something primarily because other people are doing it, regardless of their own beliefs, which they may ignore or override. The bandwagon effect has wide implications, but is commonly seen in politics and consumer behavior is BANDWAGON effect where as Situation where the demand for a product by a high income segment varies inversely with its demand by the lower income segment.is SNOB EFFECT
