This paper considers a model of endogenous growth with two sectors. It shows that it may be desirable to concentrate research in one sector, and so have unbalanced growth, but that the pressure of competition in research may cause the private sector to spread research too widely, and so have growth that is too balanced. It is also shown that even if private agents concentrate research in one sector, they may do so in the wrong one.
