    Relative Purchasing Power Parity is an economic theory which predicts a relationship between the inflation rates of two countries over a specified period and the movement in the exchange rate between their two currencies over the same period.

  3. Linear programming - Wikipedia

    en.wikipedia.org/wiki/Linear_programming

    It is widely used in mathematics and, to a lesser extent, in business, economics, and some engineering problems. There is a close connection between linear programs, eigenequations, John von Neumann's general equilibrium model, and structural equilibrium models (see dual linear program for details).

    where the economic meanings of and are the equilibrium prices of various goods and the equilibrium activity levels of various economic agents, respectively. The von Neumann's equilibrium model can be further extended to the following structural equilibrium model with A {\displaystyle \mathbf {A} } and B {\displaystyle \mathbf {B} } as matrix ...

  5. LP-type problem - Wikipedia

    en.wikipedia.org/wiki/LP-type_problem

    Some geometric optimization problems may be expressed as LP-type problems in which the number of elements in the LP-type formulation is significantly greater than the number of input data values for the optimization problem. As an example, consider a collection of n points in the plane, each moving with constant velocity.

  7. Economic model - Wikipedia

    en.wikipedia.org/wiki/Economic_model

    An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical, framework designed to illustrate complex processes. Frequently, economic models posit structural parameters. [1]
