This paper endogenizes technology and human capital formation in the M
ESEM model that was developed by van Sinderen (Economic Modelling, 199
3, 13, 285-300). Tax allowances for private R & D expenditures and pub
lic expenditures on both education and R & D are effective instruments
to stimulate economic growth. Simulations with respect to market clea
ring, the importance of supply-side elements and key parameters (such
as the magnitude of spillovers and substitution elasticities) reveal t
hat tax allowances for private R & D are the most robust instrument to
increase economic growth through the accumulation of knowledge, Contr
ary to other studies that find that technology policies typically redu
ce employment, we find that overall employment rises.
