  In this work we use a proven model to study a dynamic duopolistic competition
between an old and a new technology which, through improved technical
performance - e.g. data transmission capacity - fight in order to conquer
market share. The process whereby an old technology fights a new one off
through own improvements has been named 'sailing-ship effect'. In the
simulations proposed, intentional improvements of both the old and the new
technology are affected by the values of three key parameters: one
scientific-technological, one purely technological and the third purely
economic. The interaction between these components gives rise to different
outcomes in terms of prevalence of one technology over the other.
