Housing bubble

A housing bubble (or a housing price bubble) is one of several types of asset price bubbles which periodically occur in the market. The basic concept of a housing bubble is the same as for other asset bubbles, consisting of two main phases. First there is a period where house prices increase dramatically, driven more and more by speculation. In the second phase, house prices fall dramatically. Housing bubbles tend to be among the asset bubbles with the largest effect on the real economy, because they are credit-fueled, because a large number of households participate and not just investors, and because the wealth effect from housing tends to be larger than for other types of financial assets.
