Weegy: A natural monopoly by contrast is a condition on the cost-technology of an industry whereby it is most efficient (involving the lowest long-run average cost) for production to be concentrated in a single form. [ In some cases, this gives the largest supplier in an industry, often the first supplier in a market, an overwhelming cost advantage over other actual and potential competitors. This tends to be the case in industries where capital costs predominate, creating economies of scale that are large in relation to the size of the market, and hence high barriers to entry; examples include public utilities such as water services and electricity. It is very expensive to build transmission networks (water/gas pipelines, electricity and telephone lines); therefore, it is unlikely that a potential competitor would be willing to make the capital investment needed to even enter the monopolist's market. ] User: What is Nationalism?
