Explanation:

A hypothesis is a proposed explanation, based on the evidence that is at hand, for a set of observations and looking for further investigations. A hypothesis in an economic model works under the same premise that a hypothesis in a scientific investigation. The hypothesis may be correct or incorrect, therefore it should be tested before it can accepted only if the results show that the hypothesis explains all the obtained explanations. Regarding economic model hypothesis, usually they deal with causal relationships between an observed phenomena and the origin of it.
