Shiller sees possible return of housing bubble

Once the excess housing inventory now on the market has been sold, Yale economist Robert Shiller says another housing bubble is possible. Shiller, co-creator of the Case-Shiller Index, which measures housing prices nationwide, said people are speculative enough about buying real estate that a bubble could happen. Boston is one housing market where such a bubble might take place, because the city’s property market has not fallen as drastically as other cities’ housing markets.
