These episodes look like bubbles that gradually inflate and then suddenly burst. We show that such bubbles can form in a Zeira-Rob type of model in which demand size is uncertain. Two conditions are sufficient for this to happen: A declining hazard rate in the prior distribution over market size and a positively sloped supply of capital to the industry. For the period 1971-2001 we fit the model to the Telecom sector.}, }
