Natural Monopolies/Competition/Neoclassics: For neoclassical theory, the prerequisite for perfect competition is that goods and factors can in principle (...) be divided. This is not a problem for homogeneous goods, e.g. salt, but it is impossible for e.g. machines.
If the objects under consideration become even larger, such as railway lines or motorways, there is usually only one (regional) supplier that is efficient. Then one speaks of "natural monopolies".
In order to prevent exploitation of the other side, the state can set prices for the natural monopolist.
Problem: However, since the marginal costs (below the average costs) are due to the subadditivity of the total costs, the monopolist suffers a deficit. See Subadditivity/Baumol._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
