- Income Effects depend on the income elasticity of demand for each good limit you buy. If one of the goods you buy has a negative income elasticity, that is, it is an inferior good, what must be true of the income elasticity of the other good you buy?Recent research confirms that the demand for cigarettes is not only inelastic, but it also indicates that smokers with incomes in the lower half of all incomes respond to a given price increase by reducing their purchases by amounts that are more than four times as large as the purchase reductions made by smokers in the upper half of all incomes. How can the income and substitution effects of a price change help explain this finding?The Law of Demand states that as the price of a good increases, ceteris penbus, the The relationship that exists between these two variables can be described as decreases. This can be shown graphically with demand curve or numericaly in a table using a 0

During December 2019 Faisal sold 10,000 shawarmas at a price of PKR 600/shawarma. In January 2020 one of Faisal’s competitors, Mr. Rauf, reduced the price of a similar kind of shawarma from PKR 650 to PKR 550 and Faisal could sell only 8,000 shawarmas. Using arc method, compute and interpret the relevant elasticity of demand between Faisal and his competitor’s shawarmas.
- For normal goodsA) the substitution effect of a price decrease will decrease the quantity of the good demanded while theincome effect of a price decrease will increase the quantity of the good demanded.B) the substitution and income effects of a price decrease will both increase the quantity of the gooddemanded.C) the substitution and income effects of a price decrease will both decrease the quantity of the gooddemanded.D) the substitution effect of a price decrease will increase the quantity of the good demanded while theincome effect of a price decrease will decrease the quantity of the good demanded.When you consider both of the effects on the slope of the pricing function (-t/H) from a household having higher income, what can we say about how income will affect the slope? O It will make the slope steeper It will make the slope flatter O It will not affect the slope O We don't know how it will affect the slope without more informationLaw of equi marginal utility is an important law of cardinal utility analysis. Explain this law with the help of its assumptions. Also explain the mechanism that how the total utility will be maximum at a point when the marginal utilities of both the goods become equal. Furthermore, there is a relationship between total and marginal utilities where they both pass through different stages when the consumer continues his or her consumption regularly. Describe this case briefly
