The external returns to education: UK evidence using repeated cross-sections

Augmenting a Mincerian earnings function with industry level data we estimate the external return to schooling for a repeated cross-section of individuals in the UK over the period 1994-2004. For men age 30-49 we find that a one year increase in the industry average level of schooling is associated with an increase in individual wages of 2.6 to 3.9%, around 2 to 3 fifths of the private return to schooling. We illustrate the sensitivity of external return estimates to industry ICT use and union density, and individuals' own level of schooling. (C) 2008 Elsevier B.V. All rights reserved.
