  2. Stratified sampling - Wikipedia

    en.wikipedia.org/wiki/Stratified_sampling

    Optimum allocation (or disproportionate allocation) – The sampling fraction of each stratum is proportionate to both the proportion (as above) and the standard deviation of the distribution of the variable. Larger samples are taken in the strata with the greatest variability to generate the least possible overall sampling variance.

  3. Contract curve - Wikipedia

    en.wikipedia.org/wiki/Contract_curve

    In the case of two goods and two individuals, the contract curve can be found as follows. Here refers to the final amount of good 2 allocated to person 1, etc., and refer to the final levels of utility experienced by person 1 and person 2 respectively, refers to the level of utility that person 2 would receive from the initial allocation without trading at all, and and refer to the fixed total ...

  4. Pareto efficiency - Wikipedia

    en.wikipedia.org/wiki/Pareto_efficiency

    An allocation of indivisible items is fractionally Pareto-efficient (fPE or fPO) if it is not Pareto-dominated even by an allocation in which some items are split between agents. This is in contrast to standard Pareto efficiency, which only considers domination by feasible (discrete) allocations.

  5. Resource allocation - Wikipedia

    en.wikipedia.org/wiki/Resource_allocation

    In economics, the field of public finance deals with three broad areas: macroeconomic stabilization, the distribution of income and wealth, and the allocation of resources. . Much of the study of the allocation of resources is devoted to finding the conditions under which particular mechanisms of resource allocation lead to Pareto efficient outcomes, in which no party's situation can be ...

  6. Allocative efficiency - Wikipedia

    en.wikipedia.org/wiki/Allocative_efficiency

    Allocation efficiency occurs when there is an optimal distribution of goods and services, considering consumer's preference. When the price equals marginal cost of production, the allocation efficiency is at the output level. This is because the optimal distribution is achieved when the marginal utility of good equals the marginal cost.

  7. Linear programming - Wikipedia

    en.wikipedia.org/wiki/Linear_programming

    The optimum of the linear cost function is where the red line intersects the polygon. The red line is a level set of the cost function, and the arrow indicates the direction in which we are optimizing. A closed feasible region of a problem with three variables is a convex polyhedron.

  8. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    Selecting these n h optimally can be done in various ways, using (for example) Neyman's optimal allocation. There are many reasons to use stratified sampling: [7] to decrease variances of sample estimates, to use partly non-random methods, or to study strata individually. A useful, partly non-random method would be to sample individuals where ...

  9. Pareto front - Wikipedia

    en.wikipedia.org/wiki/Pareto_front

    A significant aspect of the Pareto frontier in economics is that, at a Pareto-efficient allocation, the marginal rate of substitution is the same for all consumers. [5] A formal statement can be derived by considering a system with m consumers and n goods, and a utility function of each consumer as = where = (,, …,) is the vector of goods, both for all i.
