This paper develops a theoretical model to analyze the firms' incentives to preannounce their new products. We consider a two-period model where a single firm controls the market with one product in the first period and a new and better product is introduced in the second period, either by the...

In this paper we analyse the set of scalar algebraic Riccati equations (ARE) that play an important role in finding feedback Nash equilibria of the scalar N-player linear-quadratic differential game. We show that in general there exist maximal 2N-1 solutions of the (ARE) that give rise to a Nash...
