An approximate dynamic programming approach to solving dynamic oligopoly models (2012, methodology): “Doraszelski (2003) among others have applied the latter method for dynamic games with a low dimensional continuous state space.”
1 Moving Beyond Schumpeter: Management Research on the Determinants of Technological Innovation (2008, background): “…models that take the uncertainty and cumulativeness of innovation into account (Doraszelski, 2003; Harris & Vickers, 1985; Reinganum, 1983, 1985) assume that the players know who they are competing with and in some cases (Doraszelski, 2003), how much the competitors are investing in innovation.”
The Role of Cooperation in Responsible AI Development (2019, background): “Dasgupta and Stiglitz (1980) argue that monopolist companies will attempt to outspend their rivals on R&D to prevent a duopoly, while Doraszelski (2003) shows that there are conditions in which companies that are behind will invest to catch up.”
