It investigates the degree to which there might be both underemployment in the labour market and underinvestment in education. A central insight is that the ex-post participation decision of workers endogeneously generates increasing marginal returns to education. Although equilibrium implies underinvestment in education, optimal policy is not to subsidise education. Instead it is to subsidise labour market participation which we argue might be efficiently targeted as state provided childcare support.eneducationhome productionimperfect competitionhours of work2006-1210.1016/j.euroecorev.2006.12.0042015-12-08
