Research Cycles
This paper examines the dynamics of fundamental research by creating a model in which research allocate their efforts between improving existing fields and inventing new ones. The authors conclude that the research fields experience phases of alternating innovation and exploitation, and at other times experience constant invention until settling into semi-permanent exploitation.
