Calculation of marginal utility, how to calculate marginal utility?

The marginal utility is calculated as follows:

Marginal utility = main business income - main business cost - period expenses - main business tax and surcharge = main business income - main business cost - sales expenses - financial expenses - management expenses - main business tax and surcharge.

Profit before tax = sales revenue of the product Cost of sales of the product Amortized sales tax and additional amortized period expenses.

Product sales revenue = domestic sales revenue + export sales revenue.

The cost of goods sold refers to the cost of sales corresponding to the revenue from the sale of the product.

Amortized sales tax and surcharge = main business tax and surcharge apportionment ratio (apportioned according to sales).

Amortized period expenses = Total period expenses of the enterprise Amortization ratio (apportioned according to sales).

Apportionment ratio (%) = sales of the product 100% of the sales of all products produced by the enterprise (including the product).

The marginal utility of money refers to the increase in the total consumer utility caused by the increase of 1 unit of currency, that is, the increase in the quantity of goods that can be purchased by 1 unit of currency, and the degree of satisfaction brought to consumers. To put it simply, it is a change in currency that leads to a change in the quantity of goods, which in turn causes a change in the degree of consumer satisfaction. Marginal Utility of Money = Increment of Utility Increment of Money.

Such as the total utility function.

tu(q) = f(q), marginal utility.

is mu=dtu(q) dq, that is, the partial derivative of the total utility function to the quantity q of the commodity.

If tu=pq, then mu=p

mu/p(1)=mu/p(2)

Calculate the marginal utility according to this formula.

It is calculated using the principle of marginal utility.

For example, suppose that the utility function of a consumer is u=q, where q is the consumer's consumption and m is the income, find the consumer's demand function.

First of all, recall the general utility function: the general utility function is u=f(x1,x2), which is about two goods, and the solution is based on the consumer equilibrium: mu1 p1=mu2 p2.

In this problem, the utility function has only one commodity and income m, and income m can be regarded as another commodity, i.e., commodity 2, according to the marginal utility of mu1 p1 = m, where the marginal utility of money income m is .

So: mu1 p1 = 1).

And u=q, find the first-order partial derivative of m for u, i.e., =3 (2) and then find the first-order partial derivative of q for u, i.e., mu1= (3) substitute (2) (3) into equation (1), and sort out q=36p 2<>

The first derivative of the utility function is obtained by substituting the specific value.

The formula for calculating marginal utility is as follows: marginal utility = main business income - main business cost - period expenses - main business tax and surcharge = main business income - main business cost - sales expenses - financial expenses - management expenses - main business tax and surcharge, or marginal utility = main business income - main business cost - sales expenses - financial expenses - management expenses - main business taxes and surcharges.

Marginal utility refers to the degree of satisfaction that increases for each unit of increase in the consumption of a certain good, expressed in mu. The meaning of marginal is extra increment.

In a certain period of time, with the continuous increase in the quantity of a certain commodity consumed, the total utility obtained by consumers from it is increasing, but increasing at a decreasing rate, that is, the marginal utility is decreasing; When the consumption of goods reaches a certain level, the total utility reaches the maximum, the marginal utility is 0, and if the consumption continues to increase, the total utility will not increase, but will gradually decrease, and the marginal utility becomes negative.

Total utility divided by the amount consumed.

Marginal utility refers to the new efficiency brought about by consumers adding one unit of goods or services within a certain period of time, that is, the increase in total utility. In economics, utility refers to the ability of a commodity to satisfy a person's desires, or in other words, utility refers to the degree of satisfaction that consumers feel when they consume a commodity.

The law of diminishing marginal utility: in a certain period of time, under the condition that the consumption quantity of other commodities remains unchanged, with the increase of consumers' consumption of a certain commodity, the increment of utility obtained by consumers from each consumption unit of the continuous increase of the commodity, that is, the marginal utility is decreasing.

Know how total utility is calculated as marginal utility: total utility is equal to the sum of all marginal utilities up to that amount.

If the marginal utility is greater than 0, the total utility increases; If the marginal utility is less than 0, the total utility decreases; The marginal utility is equal to 0 and the total utility is maximum.

Meaning of Utility: The degree to which a consumer owns or consumes a good or service to satisfy a desire is known as the utility of a good or service. The utility of a good or service depends on the subjective psychological evaluation of consumers, which is determined by the intensity of consumers' desires.

The meaning of total utility: refers to the total satisfaction obtained by consumers in the consumption of a certain number of certain goods, and the level of total utility depends on the consumption level of the individual consumer, that is, the more goods consumed by consumers and the more labor consumed, the higher the total utility will be.

The meaning of marginal utility: refers to the degree of satisfaction that increases by each unit of the consumption of a certain item, expressed in mu.

Law of diminishing marginal utility.

The content is: in a certain period of time, under the condition that the consumption quantity of other goods remains unchanged, as the consumer's consumption of a certain commodity increases, the utility increment that the consumer gets from each consumption unit of the commodity that continues to increase, that is, the marginal utility is decreasing.

Difference Between Total Utility and Marginal Utility: Marginal utility is a function of total utility.

, and the total utility is the integral of the marginal utility function, and the marginal utility of a given consumption can be expressed by the slope of the total utility curve at that consumption; The total utility of the concomitant plexus of consumption can be expressed by its marginal utility curve and the area surrounded by the two axes. The total utility curve increases at a decreasing rate, concave to the transverse axis, and has a positive slope; The marginal utility curve decreases at a decreasing rate, convex to the transverse axis, and has a negative slope; When the marginal utility is positive, the total utility is in an increasing state; When the marginal utility is 0, the total utility reaches the optimal state; When the marginal utility is negative, the total utility is in a state of decreasing.

The sum of the utility for each unit of good or service consumed by a consumer in a given period of time depends on the total amount of goods consumed.

The marginal utility is calculated as follows:

Marginal utility = main business income - main business cost - period expenses - main business tax and surcharge = main business income - main business cost - sales expenses - financial expenses - management expenses - main business tax and surcharge.

Profit before tax = sales revenue of the product Cost of sales of the product Amortized sales tax and additional amortized period expenses.

Product sales revenue = domestic sales revenue + export sales revenue.

The cost of goods sold refers to the cost of sales corresponding to the revenue from the sale of the product.

Amortized sales tax and surcharge = main business tax and surcharge apportionment ratio (apportioned according to sales).

Amortized period expenses = Total period expenses of the enterprise Amortization ratio (apportioned according to sales).

Apportionment ratio (%) = sales of the product 100% of the sales of all products produced by the enterprise (including the product).

Marginal utility = main business income - main business cost - period expenses - main business tax and surcharge.

The marginal utility is calculated as follows:

Marginal utility = main business income - main business cost - period expenses - main business tax and surcharge = main business income - main business cost - sales expenses - financial expenses - management expenses - main business tax and surcharge.

Political economy has existed as an independent discipline for more than 200 years, but people's understanding of it has always been divided. The reason for this is that the academic community has not clearly understood the basic concept of "value". The value of philosophy and the value of economics are two very different concepts.

The value of economics is measured in money, and money is the measure of value. The value of philosophy is subjective evaluation and has nothing to do with money.

In the process of studying political economy, the "labor theory of value", "utility theory of value" and "marginal utility theory" confuse the value of economics with the value of philosophy, which is far-fetched and self-deceptive, and leads the study of political economy astray. Therefore, we must clarify the relationship between labor, utility, margin, and value, and get to the root of the problem.

In fact, labor determines the value of the product's output (output), not the value of the product (**). That is, the more labor invested, the more output value of the product; The more labor put in, the higher the value of the product. The value of the product is determined by the cost, and the cost is composed of the value of the five factors of production (labor, technology, resources, capital, and system), and the value of these five factors of production jointly determines the value of the product, and the value of labor is only one of them.

Wang's Political Economy redefines some basic concepts and makes major breakthroughs on many key issues. He founded the "Social Productivity Theory", which laid a solid theoretical foundation for the in-depth study of political economy. The "law of value identity" was discovered, that is, the value of production factors is equal to the value of products, which fundamentally solves the logical problem of formation and change.

Through qualitative analysis, quantitative analysis and causal analysis, the essence and law of political and economic activities are revealed.
