We consider the issues of endogenous timing and first versus second-mover advantage in differentiated-product Bertrand duopoly with asymmetric linear costs. First, we provide a thorough set of results in the cases where prices are either strategic substitutes and/or complements, dispensing with...

We compare simultaneous versus sequential moves in R&D decisions within an asymmetric R&D/Cournot model with linear demand (for differentiated products), general R&D costs, and spillovers. Simultaneous play and sequential play (with and without a specified leader) can emerge as appropriate...
