A windfall gain is an unusually high or abundant income, net profit or profit margin, that is sudden, unexpected, or, at times, anticipated.
While they differ from one account to the next, most economists hypothesize that the majority of the gains are saved, due to the Permanent Income Hypothesis.
They can occur due to unforeseen circumstances in a product's market, such as unexpected demand or government regulation.
