Firm-level social returns to education

Do workers benefit from the education of their co-workers? We examine this question first by introducing a model of learning, which argues that educated workers may transfer part of their general skills to uneducated workers, and then by examining detailed matched employer-employee panel data from Portugal. We find evidence of large firm-level social returns (between 14% and 23%), much larger than standard estimates of private returns, and of significant returns accruing to less educated workers but not to their more educated colleagues.
