Economics paradox

Allais paradox: A change in a possible outcome that is shared by different alternatives affects people's choices among those alternatives, in contradiction with expected utility theory.
The Antitrust Paradox: A book arguing that antitrust enforcement artificially raised prices by protecting inefficient competitors from competition.
Arrow information paradox: To sell information you need to give it away before the sale.
Bertrand paradox: Two players reaching a state of Nash equilibrium both find themselves with no profits gained via exploitation.
Braess's paradox: Adding extra capacity to a network can reduce overall performance.
Deaton paradox: Consumption varies surprisingly smoothly despite sharp variations in income.
Demographic-economic paradox: nations or subpopulations with higher GDP per capita are observed to have fewer children, even though a richer population can support more children.
Downs–Thomson paradox: Increasing road capacity at the expense of investments in public transport can make overall congestion on the road worse.
Easterlin paradox: For countries with income sufficient to meet basic needs, the reported level of happiness does not correlate with national income per person.
Edgeworth paradox: With capacity constraints, there may not be an equilibrium.
European paradox: The perceived failure of European countries to translate scientific advances into marketable innovations.
Gibson's paradox: Why were interest rates and prices correlated?
Giffen paradox: Increasing the price of bread makes poor people eat more of it.
Grossman-Stiglitz paradox: Inability to recoup cost of obtaining market information implies efficient markets cannot exist.
Icarus paradox: Some businesses bring about their own downfall through their own successes.
Jevons paradox: Increases in efficiency lead to even larger increases in demand.
Leontief paradox: Some countries export labor-intensive commodities and import capital-intensive commodities, in contradiction with the Heckscher–Ohlin theorem.
Lerner paradox: The imposition of a tariff on imports may raise the relative world price of that good.
Louboutin paradox: Paradox of luxury goods. The more expensive some commodity is, the less it is used after acquiring.[6]
Lucas paradox: Capital is not flowing from developed countries to developing countries despite the fact that developing countries have lower levels of capital per worker, and therefore higher returns to capital.
Mandeville's paradox: Actions that may be vicious to individuals may benefit society as a whole.
Mayfield's paradox: Keeping everyone out of an information system is impossible, but so is getting everybody in.
Metzler paradox: The imposition of a tariff on imports may reduce the relative internal price of that good.
Paradox of prosperity: Why do generations that significantly improve the economic climate seem to generally rear a successor generation that consumes rather than produces?
Paradox of thrift: If everyone saves more money during times of recession, then aggregate demand will fall and will in turn lower total savings in the population.
Paradox of toil: If everyone tries to work during times of recession, lower wages will reduce prices, leading to more deflationary expectations, leading to further thrift, reducing demand and thereby reducing employment.
Paradox of value, also known as diamond-water paradox: Water is more useful than diamonds, yet is a lot cheaper.
Productivity paradox: (also known as Solow computer paradox): Worker productivity may go down, despite technological improvements.
Scitovsky paradox: Using the Kaldor–Hicks criterion, an allocation A may be more efficient than allocation B, while at the same time B is more efficient than A.
Service recovery paradox: Successfully fixing a problem with a defective product may lead to higher consumer satisfaction than in the case where no problem occurred at all.
St. Petersburg paradox: People will only offer a modest fee for a reward of infinite expected value.
Paradox of plenty: Countries with an abundance of natural resources tend to have less economic growth and worse development outcomes than countries with fewer natural resources.
Throw away paradox: A trader can gain by throwing away some of his/her initial endowment.
Tullock paradox: Bribing politicians costs less than one would expect, considering how much profit it can yield.
