Technology Innovation and Market Turbulence: A Dotcom Example,” Working

This paper explains market turbulence, such as the recent dotcom boom/bust cycle, as equilibrium industry dynamics triggered by technology innovation.

Systematic empirical evidence from retail and banking industries supports the theoretical findings
