We investigate the impact of home computer ownership on educational outcomes during adolescence. Using longitudinal survey data from Greece, we focus on the timing of exposure to home computers for children aged 14-18 and find that those without computer access have a 10 percentage point higher probability of dropping out of school compared to those with access. Employing a panel event study framework, we show that years of schooling increase in periods after the exposure to a personal computer at home. Our results suggest that disparities in computer access may affect significantly the human capital development during adolescence.
