The Relationship Between Competition and Incumbent’s Innovation



A static model is developed to analyse the incumbent’s innovation strategy under monopoly and duopoly. A number of potential objectives for the incumbent are modelled here, including the maximization of revenue, profit, and welfare (which are common among the network industries). Its marginal cost depends upon investment in new technologies and processes. The incumbent chooses its price and its level of investment in innovation. The incumbent’s elasticity of demand under both market structures and the incumbent’s market share under duopoly determine which market structure creates more incentives to innovate. For certain values of these variables, duopoly provides more incentives to innovate than monopoly. As expected, the incentives to innovate increase when the incumbent places greater weight on social welfare.
