How are collective (or public)goods often financed?

Question

Quizplus · Accepted Answer

Collective goods are often financed through the taxation system because they are non-excludable and non-rival in consumption. This means that it is difficult to exclude someone from benefiting from the good and one person's consumption does not diminish the availability of the good for others. Therefore, it is difficult to finance such goods through market transactions or voluntary contributions, and the government often steps in to provide funding through taxes.
