Markaðshverfa

Markaðshverfa, often translated as market distortion, refers to a situation where market forces are prevented from operating freely and efficiently, leading to an suboptimal allocation of resources. This can occur due to various interventions or inherent market characteristics that deviate from the ideal conditions of a perfectly competitive market.

Common causes of markaðshverfa include government regulations such as price controls, subsidies, and trade barriers. Price ceilings, for instance, can create shortages if set below the equilibrium price, while price floors can lead to surpluses. Subsidies, though intended to support certain industries, can artificially lower production costs, leading to overproduction and inefficient resource use. Tariffs and quotas restrict international trade, limiting consumer choice and potentially increasing prices.

Other forms of markaðshverfa arise from market imperfections. Information asymmetry, where one party in a transaction has more or better information than the other, can lead to adverse selection or moral hazard. Externalities, such as pollution from a factory, represent costs or benefits that affect parties not directly involved in the economic transaction, leading to market outcomes that do not reflect the true social cost or benefit. Monopolies and oligopolies, with their market power, can restrict output and charge higher prices than would prevail in a competitive market. These deviations from perfect competition all contribute to a market's inability to achieve its most efficient outcome.
