We posit that incumbents ally with entrants following a core-knowledge discontinuity when the appropriability regime is strong. When the appropriability regime is weak, incumbents are more likely to acquire entrants. We submit that the additional consideration of complementary-asset discontinuities reveals a more integrated theoretical model of competition and cooperation between incumbents and entrants. In particular, incumbents tend to cooperate among themselves following complementary-asset discontinuities, although we highlight theoretical nuances due to different appropriability regimes. We provide falsifiable propositions, and introduce contingencies such as firm-level heterogeneity and time dynamics. 收起
