Econometric models are statistical models used in econometrics. An econometric model specifies the statistical relationship that is believed to hold between the various economic quantities pertaining to a particular economic phenomenon. An econometric model can be derived from a deterministic economic model by allowing for uncertainty, or from ...
A basic tool for econometrics is the multiple linear regression model. [8] Econometric theory uses statistical theory and mathematical statistics to evaluate and develop econometric methods. [9] [10] Econometricians try to find estimators that have desirable statistical properties including unbiasedness, efficiency, and consistency.
In particular this can happen when one model also serves as a component of a broader model. For example, the IS model of only the goods market [1]: pp. 250–260 derives the market-clearing (and thus endogenous) level of output depending on the exogenously imposed level of interest rates, since interest rates affect the physical investment ...
For such models, economists often use two-dimensional graphs instead of functions. Qualitative models – although almost all economic models involve some form of mathematical or quantitative analysis, qualitative models are occasionally used. One example is qualitative scenario planning in which possible future events are played out. Another ...
Econometrics may use standard statistical models to study economic questions, but most often they are with observational data, rather than in controlled experiments. [10] In this, the design of observational studies in econometrics is similar to the design of studies in other observational disciplines, such as astronomy, epidemiology, sociology and political science.
Econometric models are used by economists to estimate relationships between large numbers of variables, most importantly to model national economies or the world ...

In econometrics, the seemingly unrelated regressions (SUR) [1]: 306 [2]: 279 [3]: 332 or seemingly unrelated regression equations (SURE) [4] [5]: 2 model, proposed by Arnold Zellner in (1962), is a generalization of a linear regression model that consists of several regression equations, each having its own dependent variable and potentially ...
