Pareto originally used the word "optimal" for the concept, but this is somewhat of a misnomer: Pareto's concept more closely aligns with an idea of "efficiency", because it does not identify a single "best" (optimal) outcome. Instead, it only identifies a set of outcomes that might be considered optimal, by at least one person. [4]
In economics, non-convexity refers to violations of the convexity assumptions of elementary economics.Basic economics textbooks concentrate on consumers with convex preferences (that do not prefer extremes to in-between values) and convex budget sets and on producers with convex production sets; for convex models, the predicted economic behavior is well understood.
Microeconomic reform is the implementation of policies that aim to reduce economic distortions via deregulation, and move toward economic efficiency. However, there is no clear theoretical basis for the belief that removing a market distortion will always increase economic efficiency.
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 ...
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 ...
In law and economics, the Coase theorem (/ ˈ k oʊ s /) describes the economic efficiency of an economic allocation or outcome in the presence of externalities.The theorem is significant because, if true, the conclusion is that it is possible for private individuals to make choices that can solve the problem of market externalities.
If Walras's law has been satisfied, the optimal solution of the consumer lies at the point where the budget line and optimal indifference curve intersect, this is called the tangency condition. [3] To find this point, differentiate the utility function with respect to x and y to find the marginal utilities, then divide by the respective prices ...
An optimal decision is a decision that leads to at least as good a known or expected outcome as all other available decision options. It is an important concept in decision theory . In order to compare the different decision outcomes, one commonly assigns a utility value to each of them.
