Schumpeter's ghost: Is hypercompetition making the best of times shorter?

Article Abstract:

Two large longitudinal samples of firms to discover which industries, if any, exhibit performance that is consonant with Schumpeterian theory and the assertions of hypercompetition are examined. It is found that competitive advantage has become significantly harder to sustain and that the phenomenon is limited neither to high-technology industries nor to manufacturing industries.
