What principles of economics do you know?

** With the value of the two output value, the material appreciation is the key to the balance of material at the same time.

The so-called principle is that human behavior is to disguise greed for profit.

I don't listen to those shells, I only know the profit theorem first, the sub-theorem later, and then the public welfare theorem

Value**? One of the question marks is mine.

Making money is a theory, losing money is a fallacy, right? There are many times when we can't just vote based on theory.

I don't know the principle, I only know how to do it well, and I also know what ** is.

People are faced with trade-offs, the cost of something is something that is given up in order to get it, and rational people consider marginal quantities.

I know: the cost of something is something that is given up in order to get it. It means that the opportunity cost of a thing is something that is given up in order to get it.

When making any decision, such as whether or not to go to college, the decision-maker should recognize the opportunity cost that comes with every possible choice. ‍‍

The principle of surplus value and the market of desire and the main control of money and the principle of finance!

1: People face equilibrium trade-offs 2: Rational people consider marginal quantities 3: Make everyone's economic situation better.

The cost of something is to get what it gives up. As people face trade-offs, decision-making requires comparing the costs and benefits of alternative courses of action.

The principle of material conversion. From the point of view of physics, matter is indestructible, and matter is nothing but the transformation from one form to another. In the process of transformation, matter may be decomposed into multiple small parts of different forms, and eventually matter is transformed into pure energy, energy is the ultimate form of matter, including people themselves, in this sense, economics is not needed, because no matter what method people take to develop the economy, so that they can get more, maybe in a period of time can produce more than the normal level, but in terms of the balance of the system matter, the resources it consumes are also proportional, and getting more is just converting more.

People cannot create materials and resources out of nothing, and understanding this basic truth can enable us to maintain a relatively sober basic attitude towards economics.

You can't buy things without money, and you can't necessarily buy things if you have money.

I know that the principles of economics are: people face trade-offs; Rational people consider marginal quantities; People will respond to incentives; Make everyone better; ** Sometimes it can improve market results; A country's standard of living depends on its ability to produce goods and services.

1. Principle 1: People face alternating relationships. That is, in order to get something they like, they have to give up another thing; Then the so-called decision-making is to choose between these two things and finally make a trade-off.

2. Principle 2: The cost of a thing is something that is given up in order to get it. Because people are faced with alternate relationships, decisions are made about comparing the costs and benefits of alternative options, and the problem is that the cost of an action is often not easily calculated.

3. Principle 3: Rationally consider marginal quantities. The author argues that many decisions in life are related to making small, incremental adjustments to existing action plans, and these adjustments are known as "marginal changes."

4. Principle 4: People will respond to incentives. People make decisions based on comparisons of costs and benefits, and when costs and benefits change, so do people's decisions and behaviors.

So, people will respond to incentives. This incentive can be either perceived or the result of natural variation.

The Ten Principles of Economics can solve many problems. For example, the principle of trade-offs that people face can help us find balance in many directions.

In terms of revenue distribution, if we spend more money on defense to defend our country from enemy invasion, we will spend less on personal goods that we can spend to improve our domestic standard of living. For example, we have a trade-off between a clean environment and a high income level. Laws that require companies to reduce pollution will increase the cost of producing goods and services.

As a result of the increase in costs, business profits are reduced and wages paid are reduced. So, while pollution control has benefited us in a cleaner environment and the resulting improvements in health, it has come at the cost of fewer revenue for business owners, workers, and consumers. Therefore, we need to coordinate the various objectives to achieve balanced development.

1) People face trade-offs;

2) the cost of something is something that is given up in order to get it;

3) Rational people consider marginal quantities;

4) people will respond to incentives;

5) It can make everyone better;

6) The market is usually a good way to organize economic activity;

7) ** can sometimes improve market results;

8) a country's standard of living depends on its ability to produce goods and services;

9) when too much money is issued, prices rise;

10) Society faces a short-term alternating relationship between inflation and unemployment.

Rational people consider marginal quantities;

A rational person is a person who systematically and purposefully achieves his or her goals as much as possible. Rational people usually make decisions based on marginal benefits and marginal costs!

The independent variable adds one unit of marginal cost, and the amount of increase in the dependent variable is the marginal benefit. Profit is greatest when cost equals benefit.

The market is often a good way to organize economic activity

In the fifties and sixties, it was originally the state that managed all the economic operations, so that the scarce resources of the society could be allocated, commonly known as the era of eating a big pot of rice, everyone's labor was purposeful and regulated, so under such a system, it was easy to produce various problems, such as incomplete thinking, insufficient or too much production, etc., so the country that was once the first planned economy has given up such a system and replaced it with the development of a market economy (when many enterprises and families trade in the market for goods and services, the economy of allocating resources through their decentralized decision-making, usually through their decentralized decision-making).

In life, many phenomena can be explained by economic principles. Take the ten principles of economics as an example:

The first principle is that people face the problem of trade-offs. For example, when it comes to buying fruits, there are now three kinds of fruit available to us, one is an apple, one is a watermelon, and one is a banana, and we can only buy one fruit at a time. So if I buy apples, it means that I have to give up the opportunity to buy watermelons and bananas.

In the same way, if I choose to buy watermelon, I have to give up the opportunity to buy apples and bananas, and if I buy bananas, I have to give up the opportunity to buy watermelons and apples; Horse racing is also a well-known routine of trade-offs and trade-offs to maximize profits.

Principle two, measure the opportunity cost by the value of what is being given up. For example, the choice of going to college involves a large opportunity cost. If we don't go to college, we get a salary, multiplied by 12 times 3, which is one of the opportunity costs that we give up in three years, and we also have to pay a certain amount of tuition fees to go to college, and this tuition, multiplied by three, is the real cost we pay.

Principle 3: Use the comparison of marginal cost and marginal benefit to make a decision. Many decisions in life involve making small incremental adjustments to existing action plans. Economists refer to these adjustments as marginal changes.

In many cases, one can make an optimal decision by considering marginal quantities. For example, the ** of the plane ticket was originally 200 yuan, but due to various factors, the tickets for this flight were not all sold out, and now the captain proposed to sell the ticket at 100 yuan. Is this feasible?

The answer, of course, is yes. If the ticket is sold for 100 yuan**, its marginal cost may be the drink or meal that the passenger drinks or eats on the plane, which is certainly less than 100. But if you don't sell the tickets, you're going to lose a lot of tickets.

Therefore, the trade-off is that the marginal benefit is greater than the marginal cost, and the rational salesperson will dispose of the ticket at a low price, rather than losing their value in vain.

Fourth, consumer preferences and expectations for the future affect consumption choices. Because people make decisions by comparing costs and benefits, when costs or benefits change, people's behavior changes. That is, people will respond to incentives.

For example, when apples are raised, consumers will eat more pears and less apples, because the cost of eating apples is high. For orchard owners, planting and harvesting staff will be increased to increase yields, because the increase in apples can increase profits. In addition, when taxis are low, people may choose to take taxis, but after the price increases, people will choose lower buses.
