The productivity paradox
نویسنده
چکیده
The impact of ICT (information and communication technology) on economic performance has been the subject of academic research for several decades, and despite the remarkable and significant innovation in computer technology, usage, and investments, only a small growth in productivity was observed. This observations has been coined the productivity paradox. Usingmeta-analysis, my paper answers the following two questions related to the productivity paradox: What is the true effect of the ICT investment on the productivity? and Is there a publication bias among the results in empirical literature? The paper starts with an overvivew of productivity related literature, continues with the description of meta-analytical methods used in economics for publication bias detection and estimation of genuine effects and then uses them in the empirical part. The empirical part is based on a collection of more then 800 estimates of IT payoff effects from almost 70 studies written in the last 20 years. The meta-analysis reveals the presence of publication bias and estimates the ICT elasticity to be only 0.3%. JEL Classification JEL C83, O12, O32, D24

In this paper, we revisit the “IT Productivity Paradox,” which refers to the inconclusive relationship between IT investment and performance improvement found in empirical studies. We argue that the cause of the “IT Productivity Paradox” is more than empirical measurement difficulties.

The information systems “productivity paradox” has become an important catalyst for research within the IS field. This study examines how the paradox has impacted IS research through a content analysis of 150 articles published between 1996 and 2006 that cite Brynjolfsson and Hitt’s seminal productivity paradox paper (e.g., Brynjolfsson and Hitt 1996). The results show that the original paradox...
