Using the Slatsky equation of price movements, why does the law of demand always hold?

The basic form of the Slatsky equation:

Let x(p,w) be the Walrthian demand, and u * be the level of effect that the consumer achieves under the premise of **p and income w, then.

The Slatsky equation shows that the total effect (te) of the change on consumption is equal to the sum of the substitution effect (se) and the income effect (i.e.).

Economic significance: The role of the Slutsky equation is that it can decompose how much of the change in the demand for a commodity caused by the change in the demand for the commodity is caused by the substitution effect, and how much is caused by the income effect.

You're asking this question, and I'm guessing you're reading Van Ryan's Microeconomics.

The letters in this question are really not easy to type, and there are too many superscripts and subscripts. Because it's an abstract problem, it's really hard to explain without letters. In fact, if you don't read the book carefully, you look at the expressions of the substitution effect and the income effect respectively, their subtractions and subtractions, and you will find that the subtractions of the substitution effect and the subtractions of the income effect are the same.

This is a purely mathematical method, in order to make the increment change in the same direction.

Slutsky's equation is an identity where the total change in demand is equal to the substitution effect plus the income effect.

The income effect and the substitution effect are introduced to explain the shape of the demand curve, and the relative magnitude of the two is to explain whether the demand curve slopes to the lower right or the upper right (the demand curve for Giffen goods). In the study of factor markets, the backward curve of labor demand is also studied by using the two.

This is where the substitution effect and the income effect are most useful.

The Slertzky substitution effect and the Hicks substitution effect, which can produce both calculation and short-answer questions, are hot topics in the exam.

For example, to explain that the labor supply curve is curved backwards, in terms of the solution, it saves a lot of time.

The substitution effect refers to the change in the quantity of demand or the destruction caused by the change of the level of consumer satisfaction when the level of consumer satisfaction remains the same. The substitution effect is when wages increase and people replace leisure with work. This is because the price of leisure is high when wages increase.

For example, when the hourly wage is 5 yuan, the income of one hour of leisure will be reduced by 5 yuan, and when the hourly wage is 10 yuan, the income of the remaining letter will be reduced by 10 yuan for one hour of leisure. At this time, people will reduce their leisure and work more. Therefore, the substitution effect causes the supply of labor to increase as wages rise.

Income effect: refers to the change in the real income level caused by the change in the ** of the commodity, and then the change in the demand for the commodity caused by the change in the real income level. It indicates a change in the level of utility of the consumer.

This question is not simple at all, and it is only in intermediate microeconomics that the calculation of specific substitution effects and income effects will be involved. The Slatsky equation is required. The Slatsky equation is an identity where the total change in demand is equal to the substitution effect plus the income effect.

Definition of curves and equations. The coordinates of the point on the curve satisfy the equation of the curve.
