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).
The life-process model of addiction is the view that addiction is not a disease but rather a habitual response and a source of gratification and security that can be understood only in the context of social relationships and experiences. This model of addiction is in opposition to the disease model of addiction.
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 ...
Psychology was seen as unreliable to many of these economists as it was a new field, not regarded as sufficiently scientific. [9] Though a number of scholars expressed concern towards the positivism within economics, models of study dependent on psychological insights became rare. [9]
In economics, psychology, and other social sciences, regression analysis is typically used deductively to test hypotheses, but a kitchen sink regression does not follow this norm. Instead, the analyst throws " everything but the kitchen sink " into the regression in hopes of finding some statistical pattern.
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]
Psychophysiological economics differs from behavioral economics by focusing on direct measures of physiological change and observational data, in addition to attitudinal measurement. Psychophysiological economics also differs from functional magnetic resonance imaging , which is typically applied exclusively to the study of brain activity.
The economic lot scheduling problem (ELSP) is a problem in operations management and inventory theory that has been studied by many researchers for more than 50 years. The term was first used in 1958 by professor Jack D. Rogers of Berkeley, [1] who extended the economic order quantity model to the case where there are several products to be produced on the same machine, so that one must decide ...
