We study the product and process innovation choice of firms in which a managerial incentive à la Vickers (1985) is present. Taking a two-stage dynamic game approach, we show that managerial firms are led to over-invest in process innovation, as compared to standard profit-maximising firms,...

We present a two-sector model where oligopolistic firms sell differentiated products. New products are introduced over time through formal R&D activity. Market competition takes place either a la Cournot or a la Bertrand. We show that tougher competition associated wit price-setting behavior...

We illustrate the foundations of the theory of differential games, with particular regard to the definition of information sets and solutions concepts. Then, we provide a survey of several relevant applications of the theory to modelling the behavior of oligopolic firms.

We investigate a differential oligopoly game where firms compete in account Market whose demand function is always downward sloping but can take any degree of curvature. There exist two economically meaningful saddle points, one dictated by demand conditions, the other by the Ramsey rule. In...

We investigate a dynamic oligopoly game with price adjustments. We show that the subgame perfect equilibria are characterised by larger output and lower price levels then the open-loop solution. The individual (and industry) output at the closed-loop equilibrium is larger than its counterpart at...

We illustrate two differential oligopoly games using, respectively, the capital accumulation dynamics à la Nerlove-Arrow, and the capital accumulation dynamics à la Ramsey. We prove that these games benefit from the property that closed-loop memoryless solutions degenerate into open-loop...

We illustrate a differential oligopoly game where firms compete à la Cournot in homogeneous goods in the market phase, and invest in advertising activities aimed at increasing consumers' reservation price. Such investments produce external effects, characterizing the advertising activity as a...

We consider a differentiated oligopoly where firms compete a la Cournot in the market phase, and each firms may invest in advertising activity, to enlarge its market size. Each firm`s advertising effort has positive external effects on the market size of all rivals. We derive the open-loop (and...

We consider a nynamic oligopoly where firms invest to increase product differentiation and an externality effect operates in the R&D activity. We compare the steady state solutions under alternative decision rules, namely, the open-loop and the closed-loop Nash equilibrium. Significant...

We investigate a dynamic oligopoly game where goods are differentiated and prices are sticky. We study the open-loop Nash equilibrium, and show that the latter equilibrium entails a larger level of steady state production as compared to the former; both equilibria entail a larger level of...
