## How is walrasian demand function derived?

Solution: The Walrasian demands are x1(p, w) = w/p1 and x2(p, w) = 0 for both type of lexicographic preferences. Even though the preferences are discontinuous, the demands are not only continuous but are also very simple.

## What do Hicksian demands show?

Hicksian demand curves show the relationship between the price of a good and the quantity demanded of it assuming that the prices of other goods and our level of utility remain constant.

**How do you derive an uncompensated demand function?**

To get uncompensated demand fix income and prices which fixes the budget line. To get uncompensated demand fix income and prices which fixes the budget line. Get onto highest possible indifference curve. Compensated demand, Hicksian demand, is a demand function that holds utility fixed and minimizes expenditures.

**What is Hicksian approach?**

The Hicksian method, developed by British economist John R. Hicks, reduces hypothetical consumer income in the calculation to determine the impact of the substitution and income effects. In the economy, taxation could be an arbitrary means of reducing consumer income.

### How is the demand equation derived from a demand schedule?

Qd = a – b(P)

- Q = quantity demand.
- a = all factors affecting price other than price (e.g. income, fashion)
- b = slope of the demand curve.
- P = Price of the good.

### How do you find the Hicksian demand from expenditure function?

Hicksian demand is the derivative of the expenditure function. ∇p e(p, v) = h∗(p, v) − 0 since F does not depend on p. Walrasian demand equals the derivative of the indirect utility function multiplied by a “correction term”.

**Is Walrasian and Marshallian demand function same?**

Although Marshallian demand is in the context of partial equilibrium theory, it is sometimes called Walrasian demand as used in general equilibrium theory (named after Léon Walras).

**What is the Hicksian approach?**

#### What is Hicksian compensation?

The Hicksian demand is the solution to the cost minimization problem in which the consumer chooses a bundle of goods to minimize the expenditure subject to a utility-level constraint. The Hicksian demand is also called the compensated demand.

#### What is compensated and uncompensated demand?

Compensated demand, Hicksian demand, is a demand function that holds utility fixed and minimizes expenditures. Uncompensated demand, Marshallian demand, is a demand function that maximizes utility given prices and wealth.

**How does the Hicksian demand function isolate the substitution effect?**

The Hicksian demand function isolates the substitution effect by supposing the consumer is compensated with exactly enough extra income after the price rise to purchase some bundle on the same indifference curve. If the Hicksian demand function is steeper than the Marshallian demand, the good is a normal good; otherwise, the good is inferior.

**Is Hicksian demand more sensitive to price than Marshallian demand?**

Hicksian demand eliminates the (positive) income effect, so that the only remaining effect is the unambiguously negative substitution effect. Thus, Hicksian demand for an inferior good is more sensitive to price that Marshallian demand.

## What happens to demand when the price of an inferior good?

But let’s look at the case of an inferior good. By definition, when the price of an inferior good increases Marshallian demand tends to fall due to the substitution effect, but increase due to the income effect. In other words, there is one negative effect and one positive effect on demand.

## What is the difference between Giffen and Hicksian demand function?

If the good is a Giffen good, the income effect is so strong that the Marshallian quantity demanded rises when the price rises. The Hicksian demand function isolates the substitution effect by supposing the consumer is compensated with exactly enough extra income after the price rise to purchase some bundle on the same indifference curve.
