Diffusion and Competition of Innovative Cardiological Technologies

Competition in Matching Technologies∗

We analyze the trade-off between monopoly and competition in matching markets. Intermediaries use prices to sort agents on one side of the market, while, on the other side, they rely solely on an imperfect screening technology. The socially efficient outcome is characterized by an optimal quality provision and an efficient market coverage: matched agents are matched assortatively and all agents...

Innovative reproductive technologies: risks and responsibilities.

In view of the global burden of subfertility, efforts are required to make assisted reproduction more effective, less burdensome and more equally accessible. New reproductive technologies are frequently introduced in clinical practice without a sound evaluation of their efficacy, effectiveness and/or safety. Safety issues in this context refer both to patients (mostly women) undergoing the rele...

Innovative Uses and Emerging Technologies in Endoscopy

Disruptive Technologies and the Emergence of Competition

We formalize the phenomenon of disruptive technologies that initially serve isolated market niches and, as they mature, expand to displace established technologies from mainstream segments. Using a novel model of horizontal and vertical di®erentiation with discrete customer segmentation, we show how the emergence of technology competition depends on numerous factors including the number of ̄rms...

Anticipation in innovative investment under oligopolistic competition

We study firms' optimal investment behavior in a dynamic duopoly framework. Embodied technological progress makes later generations more productive. The resulting model is a differential game combined with a vintage capital goods structure. Since such a framework has not been analyzed before, existing concepts have to be modified. Our numerical analysis first shows that a technological breakthr...
