NotesSpeculative bubbles typically cause economic inefficiencies. As they grow they divert economic resources towards unproductive pursuits. They can also price the real users of assets out of the market. For example, a real estate bubble that leads to over-construction and a city filled with empty homes that are simply flipped over and over by investors while residents of the city find homes less and less affordable.---When speculative bubbles burst they can cause financial instability and may require the government to spend or create money to stabilize the system. Bursting bubbles may trigger a recession as they can damage the public's appetite for productive risk taking.
