Rent seeking in the context of "Cronyism"

The infant industry argument is an economic rationale for trade protectionism. The core of the argument is that nascent industries often do not have the economies of scale that their older competitors from other countries may have, and thus need to be protected until they can attain similar economies of scale. The logic underpinning the argument is that trade protectionism is costly in the short run but leads to long-term benefits.

Infant industry protection is controversial as a policy recommendation. As with the other economic rationales for protectionism, it is often abused by rent seeking interests. In addition, countries that put up trade barriers to imports often face retaliatory barriers to their exports, potentially hurting the same industries that infant industry protection is intended to help. Even when infant industry protection is well-intentioned, it is difficult for governments to know which industries they should protect; infant industries may never grow up relative to adult foreign competitors.

In neoclassical economics, a market distortion is any event in which a market reaches a market clearing price for an item that is substantially different from the price that a market would achieve while operating under conditions of perfect competition and state enforcement of legal contracts and the ownership of private property. In other words, a distortion is "any departure from the ideal of perfect competition that therefore interferes with economic agents maximizing social welfare when they maximize their own". A proportional wage-income tax, for instance, is distortionary, whereas a lump-sum tax is not. In a competitive equilibrium, a proportional wage income tax discourages work.

In perfect competition with no externalities, there is zero distortion at market equilibrium of supply and demand where price equals marginal cost for each firm and product. More generally, a measure of distortion is the deviation between the market price of a good and its marginal social cost, that is, the difference between the marginal rate of substitution in consumption and the marginal rate of transformation in production. Such a deviation may result from government regulation, monopoly tariffs and import quotas, which in theory may give rise to rent seeking. Other sources of distortions are uncorrected externalities, different tax rates on goods or income, inflation, and incomplete information. Each of these may lead to a net loss in social surplus. Market distortions are events, decisions, or interventions taken by governments, companies, or other agents, often in order to influence the market. They are often the response on market failures, i.e., circumstances that prevent perfect competition and achieving an optimal equilibrium in the market.
