In economics, imperfect competition refers to a situation where the characteristics of an economic market do not fulfil all the necessary conditions of a perfectly competitive market. Imperfect competition causes market inefficiencies, resulting in market failure . [ 1 ]
The greater the degree of imperfect competition in the output market, the lower the real wage and hence the more the reduction falls on leisure (i.e. households work more) and less on consumption. Hence the fiscal multiplier is less than one, but increasing in the degree of imperfect competition in the output market. [23]
The second group of explanations focuses on international capital market imperfections, mainly sovereign risk (risk of nationalization) and asymmetric information. Although the expected return on investment might be high in many developing countries, it does not flow there because of the high level of uncertainty associated with those expected ...
In welfare economics, the theory of the second best concerns the situation when one or more optimality conditions cannot be satisfied. [1] The economists Richard Lipsey and Kelvin Lancaster showed in 1956 that if one optimality condition in an economic model cannot be satisfied, it is possible that the next-best solution involves changing other variables away from the values that would ...
In effect, they internalise the market in knowledge within the firm. The theory claims the internalization leads to larger, more multinational enterprises, because knowledge is a public good . [ 4 ] Development of a new technology is concentrated within the firm and the knowledge then transferred to other facilities.
Lucas (1973) [r] proposed a business cycle theory based on rational expectations, imperfect information, and market clearing. While building this model, Lucas attempted to incorporate the empirical fact that there had been a trade-off between inflation and output without ceding that money was non-neutral in the short-run.

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 ...
Capital market shares some of the "imperfections" of the labor market discussed above: long term relationships between banks and borrowers act like the long term employment relationship between an employer and their workers. Like layoffs in the labor market, there is credit rationing in the financial market. Also, a typical loan contract is ...
