The labor productivity effects of portability and connectivity of information and communication technology (ICT) are studied with Finnish firm-level data. It is found that a computer with only processing and storage capabilities boosts labor productivity by 9% (corresponding to 5% output elasticity), portability by 32%, wireline connectivity by 14%, and wireless connectivity by 6%. The findings are in line with previous literature and comparisons to ICT costs suggest that firms equate marginal costs and returns. Although increasing ICT penetration can no longer be a major source of productivity growth in developed economies, the relatively new characteristics studied can.
