  2. Multiplier (economics) - Wikipedia

    en.wikipedia.org/wiki/Multiplier_(economics)

    In macroeconomics, a multiplier is a factor of proportionality that measures how much an endogenous variable changes in response to a change in some exogenous variable. For example, suppose variable x changes by k units, which causes another variable y to change by M × k units.

  3. Optimality model - Wikipedia

    en.wikipedia.org/wiki/Optimality_model

    To determine the optimum time spent on a behavior, one can make a graph showing how benefits and costs change with behavior. Optimality is defined as the point where the difference between benefits and costs for a behavior is maximized, which can be done by graphing the benefits and costs on the y-axis and a measure of the behavior on the x-axis.

    The R programming language can be used for creating Wikipedia graphs. The Google Chart API allows a variety of graphs to be created. Livegap Charts creates line, bar, spider, polar-area and pie charts, and can export them as images without needing to download any tools. Veusz is a free scientific graphing tool that can produce 2D and 3D plots ...

    Also called resource cost advantage. The ability of a party (whether an individual, firm, or country) to produce a greater quantity of a good, product, or service than competitors using the same amount of resources. absorption The total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves ...

  6. Biological network - Wikipedia

    en.wikipedia.org/wiki/Biological_network

    In biology, pairwise interactions have historically been the focus of intense study. With the recent advances in network science , it has become possible to scale up pairwise interactions to include individuals of many species involved in many sets of interactions to understand the structure and function of larger ecological networks . [ 27 ]

  7. Power graph analysis - Wikipedia

    en.wikipedia.org/wiki/Power_graph_analysis

    In computational biology, power graph analysis is a method for the analysis and representation of complex networks. Power graph analysis is the computation, analysis and visual representation of a power graph from a graph . Power graph analysis can be thought of as a lossless compression algorithm for graphs. [1]

  8. Lucas critique - Wikipedia

    en.wikipedia.org/wiki/Lucas_critique

    It tells economists, primarily, how not to do economic analyses. The Lucas critique suggests that if we want to predict the effect of a policy experiment, we should model the "deep parameters" (relating to preferences , technology , and resource constraints ) that are assumed to govern individual behavior: so-called " microfoundations ."

  9. Economic region of production - Wikipedia

    en.wikipedia.org/wiki/Economic_region_of_production

    In economics and microeconomics, the economic region of production is an offshoot of the theory of production function with two variables. It is a cost-oriented theory which defines the region in which the optimal factor combination will lie. [1] It serves as a map of the region of optimal production.
