Technology spillovers from high-productivity countries in the North al
low low-productivity countries in the South to improve productivity in
high-tech sectors relatively easy. However, the South's share in worl
d goods markets for high-tech products is relatively low, which reduce
s opportunities for learning by doing. Our simple Ricardian endogenous
growth model shows how the balance between toughness of competition i
n trade and the strength of North-South spillovers determines whether
productivity levels diverge, partially converge or fully converge in t
he long run. If convergence prevails, the North is confronted with dec
lining employment in high-tech sectors. Temporary (trade) policy measu
res can turn a diverging economy into a converging one.
