Bipartite conflict networks with returns to scale technology

•We develop a model of complete bipartite conflict networks with returns to scale technology.•Explain how conflict technology affects the behavior of agents.•Identify two main factors that determine the impact of returns to scale technology on agents’ equilibrium behaviors.•Establish that an inverted U relationship between the returns to scale technology and (individual and total) equilibrium efforts can exist.•Offer a possible explanation for some phenomena observed in real-world conflict networks.
