From: Dynamics from open innovation to evolutionary change

H&A model OCE model
Mutation ratio Level of open innovation
Death rate Level of complexity (competition level)
Cost of cooperation [ Firm A = γABPA ]
[ Firm B = γBAPB ]
γAB : Degree of losing monopoly profit of firm A by sharing its technology with firm B
γBA: Degree of losing monopoly profit of firm B by sharing its technology with firm A
PA : Value of technology owned by firm A
PB : Value of technology owned by firm B
Benefit of receiving [ Firm A = αABPB + βAB ]
[ Firm B = αBAPA + βBA ]
αAB : Degree of technology convergence from firm B technology to firm A technology
βAB : Opportunistic benefit of firm A by not investing in and freely using firm B technology
αBA : Degree of convergence from firm A technology to firm B technology
βBA : Opportunistic benefit of firm A by not investing in and freely using firm B technology
