In this paper, we specify a theoretical dynamic oligopoly model with regard to asymmetric firms. We then estimate a structural dynamic model of demand and pricing relations for the semiconductor industry. Using quarterly firm-level output and cost data as well as industry prices from 1974 to...

Literature on environment and endogenous growth suggests that sustainable growth critically depends on technological innovations. In this paper, technological progress takes the form of an expansion in the variety of inputs. In a first scenario, a closed economy is endowed with a renewable...

To address how systems of computational agents, working alone, in teams, or with humans, can cooperate to solve problems and advance technology more autonomously than the current generation of remotely controlled unmanned systems, it is increasingly clear that a revolution in computing...
