What mechanisms drive the group size evolution of social conversations? How does schisming take place in dynamically-changing conversations? Are there any universal driving mechanisms taking place?

This analytical foundation resulted in an unprecedented ex‐ plosion in the design and production of synthetic chemicals during and post-World War II.

We study how network externalities affect research and development (Rinvestments by a non−cooperative duopoly that offers compatible products. We find that multiple RDequilibria may arise when network externalities are non linear in the number of consumers. The lowest RDequilibrium corresponds to the case where network externalities are absent. However, even in the presence of network externali...
