  2. Market failure - Wikipedia

    en.wikipedia.org/wiki/Market_failure

    Different economists have different views about what events are the sources of market failure. Mainstream economic analysis widely accepts that a market failure (relative to Pareto efficiency) can occur for three main reasons: if the market is "monopolised" or a small group of businesses hold significant market power, if production of the good or service results in an externality (external ...

  3. Complete market - Wikipedia

    en.wikipedia.org/wiki/Complete_market

    Here, goods are state-contingent; that is, a good includes the time and state of the world in which it is consumed. For instance, an umbrella tomorrow if it rains is a distinct good from an umbrella tomorrow if it is clear. The study of complete markets is central to state-preference theory.

    Used cars market: due to presence of fundamental asymmetrical information between seller and buyer the market equilibrium is not efficient—in the language of economists it is a market failure. Around the 1970s the study of market failures came into focus with the study of information asymmetry. In particular, three authors emerged from this ...

    en.wikipedia.org/wiki/Imperfect_competition

    The goods produced are circulated in only one market, and no other company intends to enter the market. The two companies have a lot of control over market prices. [ 11 ] It is a particular case of oligopoly, so it can be said that it is an intermediate situation between monopoly and perfect competition economy.

    Information asymmetry occurs in situations where some parties have more information regarding an issue than others. It is considered a major cause of market failure. [56] The contribution of information asymmetry to market failure arises from the fact that it impairs with the free hand which is expected to guide how modern markets work.

    How goods shall be produced: The fundamental problem of how goods shall be produced is largely hinged on the least-cost method of production to be adopted as gainfully peculiar to the economically decided goods and services to be produced. On a broad note, the possible production method includes labor-intensive and capital-intensive methods.

    Non-satiation: While non-satiation is a very weak assumption, there exist two primary cases in which it fails to hold. Firstly, if preferences have a satiation point (e.g. Central Banks who target inflation have a satiation point at the inflation rate that they target). Secondly, if goods can only be purchased in discrete chunks, this ...

    en.wikipedia.org/wiki/Production–possibility...

    Market failure (such as imperfect competition or externalities) and some institutions of social decision-making (such as government and tradition) may lead to the wrong combination of goods being produced (hence the wrong mix of resources being allocated between producing the two goods) compared to what consumers would prefer, given what is ...
