Using a two-stage model describing the optimal R&D choice of firms operating in an oligopoly market for several substitute goods we predict a convex (U-shaped) relationship between competition and innovation; that is, innovation declines as a function of product market competitiveness up to a...

Very tight generation capacity (‘underinvestment’) in competitive electricity markets is a major concern to policymakers. Employing a model with endogenous capacity, capacity mix, operations and with uncertain demand we show that ‘underinvestment’ is due to the rational (non-abusive)...

This paper assesses the effect of intermittently renewable energy on generation capacity mix and market prices. We consider two generating technologies: (1) conventional fossil-fueled technology such as combined cycle gas turbine (CCGT), and (2) sunshine-dependent renewable technology such as...
