Existing models of R&D are not easily reconciled with four observable aspects of R&D: initial technologies (“ideas”) need to be developed further, only a minority of initial ideas is successfully brought to the market, production and process innovations take place simultaneously (whereby,...

P-p plots contain all the information that is needed for scale-invariant comparisons. Indeed, Empirical Distribution Function (EDF) tests translate sample p-p plots into a single number. In this paper we characterize the set of all distinct p-p plots for two balanced sample of size n absent...

Allowing firms to cooperate in their R&D is an industrial policy which has received much attention in recent economics literature. Many of these contributions are based on the seminal analysis of d?Aspremont and Jacquemin [1988]. We provide a general version of their model which encompasses...

We propose a quantification of the p-p plot that assigns equal weight to all distances between the respective distributions: the surface between the p-p plot and the diagonal. This surface is labelled the Harmonic Weighted Mass (HWM) index. We introduce the diagonal-deviation (d-d) plot that...

Recent laboratory experiments support the popular view that the introduction of corporate leniency programs has significantly decreased cartel activity. The design of these repeated game experiments however is such that engaging in illegal price discussions is the only way for subjects to avoid...

We consider the efficiency of Cournot and Bertrand equilibria in a duopoly with substitutable goods where firms invest in process R&D. Under Cournot competition firms always invest more in R&D than under Bertrand competition. More importantly, Cournot competition yields lower prices than...
