We suggest a family bargaining model where human capital investment decisio
ns are made non-cooperatively in a first stage, while day-to-day allocation
of time is determined later through Nash bargaining, but with non-cooperat
ive behaviour as the fall-back. One finding is that overinvestment in educa
tion may be even more of a problem in such a semi-cooperative model than in
a fully non-cooperative one. Even though both the semi-cooperative model a
nd the fully non-cooperative model predict overinvestment in education, pol
icy conclusions that follow from the two models are distinctly different.
