some questions that cannot be ansered?

Monopoly  questions that cannot be ansered of natural monopoly (for example, a city usually builds a water network, and if it is more economically, it is not cost-effective, but it is a monopoly of more cost-effective) .

Technological innovation monopoly (this is well explained, such as

 Q, Google, Microsoft, which is a monopolistic company).

Administrative monopoly (this is the worst, for example, by government directives, how many taxi companies can only be limited, how many taxis can only be used to restrict competition)2.

Externalize For example, a person driving on the road does not seem to hinder anyone, but he exhausted the exhaust,

Occupying the public highway, in fact, there is externalize. Especially after the number of people driving.

The externalizes accumulate and become air pollution and traffic jams. This is the negative externalize of driving.

There are also good examples of externalizes. For example, a park in the middle of the city has a beautiful environment and convenient facilities.

The surrounding house prices may rise a little. This is the positive externalize of building a park.difficult to solve in the traditional market economy.

Sometimes it is necessary to ask for legal or administrative instructions. It should be noted that most economists believe that human nature is greedy rather than moral.
