Consider Stackelberg competition where the incumbent monopolist is the first mover. The symmetric reaction of the other firms to the investment of 32 Blundell et al. (1999). 32 1. Competition, Leadership and Entry the leader is still governed by their equilibrium first order condition z = (1 − z)n−2 (1−zL )V , where now zL is the investment of the leader, which is known at the time of the choice of the other firms. The above rule cannot be solved analytically, but it shows again that the investment of the outsider firms must be decreasing in the investment of the leader, ∂z/∂zL < 0: the higher the latter, the smaller the probability that no one innovates and therefore the expected gain from the investment of the followers is reduced.

It may be that the same innovator just keeps it secret and exploits its leadership on the market until an imitator replaces it. In both ways the expected gain from an innovation is what drives firms to invest in R&D. In this framework we can also study alternative market structures depending on the timing of moves and on the entry conditions. Consider a simple contest between firms to obtain a drastic innovation which has an expected value V ∈ (0, 1) for the winner and generates no gains for the losers.

2 Increasing Marginal Costs and Product Differentiation The example adopted until now was extremely simple and stylized. Perfectly homogenous goods and marginal costs of production that are always constant are quite unrealistic features for many sectors. Most traditional markets are characterized by more complex shapes of the cost function and by substantial differentiation between products. Consider the market for cars. Companies like GM, Ford, Toyota, Nissan, VW, Porsche, Renault or FIAT offer many different models, sometimes under different brands (for instance Alfa Romeo, Lancia, Maserati and Ferrari for FIAT), and always in multiple versions by engine size, color, varieties of optional tools, and so on: each product appeals to a different class of customers and is sold at a different price.
