Ask a question about economics, ask a few questions about economics, and help explain why

Exclusivity means that when a consumer pays for a product or service, others cannot enjoy the benefits of that product or service. Competitiveness refers to the fact that an increase in consumers leads to an increase in production costs.

It's that you use it, and others can't use it. When A buys a piece of chocolate, he gets the right to consume it, and no one else can consume the same piece of chocolate.

Rival refers to the increase in the cost of production caused by the increase of consumers, and the cost of production will increase for each additional piece or private good provided, so competitiveness is a characteristic of private goods.

TV: That's not right upstairs. Television broadcasting is exclusive because you pay for your home TV set. There is no competition because several share a signaling network.

I explain it to you in colloquial language.

Exclusivity means that the consumption of the product can exclude other people from consuming the goods.

Competitiveness means that the consumption of one more person requires a cost.

Television broadcasting, cable is exclusive, if you don't have a cable device, you can't watch it, you can be excluded. But the Radio and Television Department has exclusivity. There is no competition, which means that you will not increase the cost of TV broadcasting.

24,a "Inelasticity of the wage rate for workers" indicates that the labor force of workers **** or decline has little impact on the demand for labor, that is, even if wages fall more, factories will not hire more workers because of the decline in wage costs, because the demand for workers will not change much. So, wages go down, and no more workers are recruited, and the total wage goes down

25, C in layman's terms, that is, the change in demand is not as large as the change in **, and the sharp decline in ** only makes the sales increase slightly, that is, the demand is inelastic to **.

I hope my easy-to-understand answer can help you, with a 99% accuracy rate

24 Option D: The inelasticity of the demand for workers indicates that even if wages fall more, factories will not hire more workers because of the decline in wage costs, because the demand for workers will not change much.

However, the magnitude of the change in wages and the elasticity of demand are not specifically given, so it is impossible to determine whether total wages will increase or decrease.

25 Option C**Elasticity of demand = change in demand **Change amplitude = 1% 10% = **Decrease of 10% causes an increase in expenditure of 1% It can be understood as a rise in demand of 1% The elasticity calculated here is less than 1 so it is inelastic.

Elastic: that is, the absolute value of the elasticity coefficient is greater than 1, when the change of this type of commodity **, the demand caused by the ** is larger, if the ** change is 1%, then the demand change will exceed 1%. That is, the impact on demand is obvious.

Unit elasticity: that is, the absolute value of the elasticity coefficient is due to 1, and the change of this type of commodity ** will cause the demand to change in the opposite direction to the same degree. A 1% change would result in a 1% increase.

Lack of elasticity: The absolute value of the elasticity coefficient is less than 1**Volatility has less impact on demand. **1% change, less than 1% change in demand

24 out of A (inelastic).

25 Choice A (** change, which caused a greater change in demand, led to a 1% increase in total expenditure, which is elastic).

Debt itself is not wealth, but a spatial concept of disparity in a particular environment or a particular society. In this sense, money is not wealth, it is just a way to represent wealth, which also requires a specific environment.

There are two problems in the story itself, one is whether it is possible to borrow money or whether credit can represent money; Second, in this specific environment, the generation of debt is a cycle, and if it is not circular, then the debt cannot be paid.

You can follow up on what exactly you want to ask.

The shopkeeper didn't get the woman's 1,000 yuan, that is, the shopkeeper lost 1,000 yuan.

The shopkeeper could have gotten the $1,000.

In fact, there is no debt, because everyone owes one debt, and there happens to be another debt of the same value in the hands of another person, and these happen to be a cycle. Even if the traveler doesn't show up, they can still pay off their debts, provided they both know each other. For example, A, B, C, D, E, A, 1000 B, B, C, 1000 ...

E owes A 1000. A took E's 1000 to offset B's, B used it to offset C's, and finally returned it to E's own hands, so it is equivalent to E having no expenditure and no income.

A simple circular equilibrium relationship, commonly known as a "triangular debt".

It's equivalent to you owe me 100 yuan, I owe him 100 yuan, he owes you 100 yuan, and then he uses the 100 yuan I owe him to offset the 100 yuan he owes you, which is equivalent to the three of us owe money written off.

I don't know how many companies have been brought down by this triangular debt.

1. All individuals feel that the demand for drug-based drugs is very elastic (ordinary people will not use it, as long as a specific group of people will use the commodity, the use of the commodity by this specific group of people will not decrease with the fluctuation of the commodity), and the demand for computers is very elastic (when the computer is the first to be the most elastic, people will reduce the purchase of the product accordingly, and when the first person declines, how can many people buy it, and the computer is not a necessity). Therefore, when the quantity increases with technological progress, the equilibrium of drugs does not change as much as the change of computers. In terms of quantity, the number of computers will be greatly improved, and the number of drugs will not change.

Consumers' total spending on medicines has also not changed much.

The elasticity of demand is 0, and the demand curve is a perpendicular line.

The seller is taxed at 7 yuan, and the supply curve is shifted upward by 7 units, because the demand line is vertical, and the equilibrium** also rises by 7 yuan.

If the elasticity of demand is greater than 0, it is less than infinity. The demand curve slopes downward, the supply line shifts upwards by 7 units, and the equilibrium** rises by less than 7

If the elasticity is infinite, the demand line is horizontal, and the equilibrium** remains unchanged.
