What is the marginal utility of a commodity, and the marginal utility of a certain commodity refers

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.

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 together 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 solved 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.

Answer] :d marginal utility refers to the total utility increment obtained for each additional unit of consumption of goods or services.

Utility: The property that all needed goods will bring satisfaction and happiness to consumers is called the utility of goods.

Total utility: Economists refer to the total amount of satisfaction that consumers get from consuming a certain amount of goods in a certain period of time as total utility.

Marginal utility: The utility of a commodity varies with the number of goods. The utility that a consumer increases or decreases by increasing or decreasing the amount of consumption per unit of a good is called marginal utility.

The law of diminishing marginal utility: the marginal utility of commodities gradually decreases with the increase of the quantity of commodities, and this phenomenon is common among all commodities.

The teacher explained in detail, and in school, it was very easy for people to learn.

I am very grateful to Mr. Yu Yingchun for listening to his "English (II)", which was passed at one time, and Mr. Yu's teaching was more vivid and the learning method was very good. I can finally get my graduation certificate this year, thank you for this good platform.
