Visualizações: 1291Resumo
The mobile phone devices industry, whose structure is an oligopolistic technological frontier, suffered a structural change in the 2000s, with firms once leaders giving way to emerging ones. This study’s hypothesis is that this chance happened due to different innovation strategies adopted by the firms. The objective is to analyze innovation strategies’ influence on business performance of the industry’s firms in general, with Apple, Nokia and Samsung cases in particular – considered representative firms of the industry for the period. The methodology used was the game theory, comparatively analyzing two games with Nash-Bayesian equilibrium. The results show that, in the face of an aggressive strategy of innovation by products of the first firm (Apple), there is a worse outcome for the company that competes by innovations by product (Nokia) than by markets (Samsung). It is concluded that companies should pay attention to their innovative strategies to remain operative in dynamic markets.
