What do economic models do?
An economic model is a simplified version of reality that allows us to observe, understand, and make predictions about economic behavior. The purpose of a model is to take a complex, real-world situation and pare it down to the essentials.
Can economic theories be tested?
Indeed, in most textbooks at some stage we read that unfortunately economists, unlike physicists, cannot test their theories under controlled conditions, and therefore theory validation must rely on statistical analysis of data collected in the field (econometrics) or intuitive judgement (introspection).
What is a theory definition?
A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts. A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable.
What do you mean by econometrics?
