Abstract: 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. Using meta-analysis, my thesis 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 thesis 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%.
