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)...

The long lead time required to add new capacity in the electricity generation industry means that daily demands are necessarily served by capacity already installed. However, in a competitive market, even if the installed capacity was designed to serve the projected demands, frequent surpluses...

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...
