Collision, Plasticity, and the Creation of Possibilities

Abstract

This paper discusses a model where mutation occurs in the population due to "collision", such as immigration, the introduction of new technology, and environmental changes. The proportion of mutations in the population is determined by a parameter called "plasticity", and the population goes to a long-run equilibrium through Darwinian adjustment after the collision. This paper shows that having plasticity can be better than maintaining the existing convention in the long-run equilibrium even when the existing convention is more successful than the average mutation.
