R&D subsidies are a common tool of technology policy, but little is known about the effects
they have on the behavior of firms. This paper presents evidence on the effects that R&D …

This paper reports a search for general tendencies among models that look at spillovers in
innovative activities. A number of inferences are detailed that appeared in a wide class of …

Two questions are examined within a model of vertical differentiation. The first is whether
cost-reducing innovations are more likely to be observed in regimes of more intense …

This paper compares Bertrand and Cournot equilibria in a differentiated duopoly with
substitute goods and product R&D. I find that R&D expenditure, prices and firms' net profits …

In this paper, we compare Bertrand and Cournot equilibria in a differentiated duopoly with
linear demand and cost functions. We extend the Singh and Vives (1984) model by allowing …

This paper investigates how the incentives for cost reduction in a differentiated industry
depend upon the degree of product substitutability. When goods are imperfect substitutes …

The amount of cost reduction or effective R&D that results in a symmetric sequential Nash
equilibrium with quadratic payoffs and differentiated goods, is shown to increase with …

This paper studies vertical R&D spillovers between upstream and downstream firms. The
model incorporates two vertically related industries, with horizontal spillovers within each …

This paper demonstrates that the standard conclusions regarding the comparison of Cournot
and Bertrand competition are reversed in a vertically related market with upstream monopoly …
