They differ from natural, financial and labour resources. Economists call them social welfare. It means that information and knowledge do not decrease while being used. When a person aquires some knowledge, it does not mean that another person’s ability to aquire the same quantity of knowledge is decreased. Besides, information and knowledge do not decrease according to the number of people using them. Information and knowledge represent the basis for solving some tasks. Accordingly, increases the number of people engaged in intellectual work. Information and knowledge represent both the basis and the result of their work.
