Cartilage lesions of the knee, talus, ankle and hip generate chronic symptoms represented by pain associated to weight bearing, stiffness, locking and swelling of damaged joints that reduce the ability to walk, work and to carry out sports range of motion. Cartilage degeneration reduces the...

We use a dynamic model to study the effects of technology and learning on the long run economic growth rates of a leading and a lagging region. New technologies are developed in the leading region but technological improvements in the lagging region are the result of learning from the leading...

We theoretically study the impact of two innovation policies on economic growth in a region that is creative in the sense of Richard Florida and that uses digital technologies to produce a final consumption good. The use of these digital technologies in our creative region gives rise to...

In this chapter, we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that...

The technological effects of innovative regions on lagging regions' labor markets have not been yet well understood, especially in the urban-rural context. I introduce a theoretical model that yields insight into the interactions between high-technology and lagging regions. While, through...

This paper extends the existing literature on strategic R&D alliances by presenting a model of innovation networks with endogenous absorptive capacity. The networks emerge as a result of bilateral cooperation over time between firms occupying different locations in the knowledge space. Social...

The present paper proposes a new way of thinking regarding the relation between innovation and knowledge using a Physics-borrowed model, trying to prove whether knowledge resources can "flow" (be percolated) in a network or a grid, in order to be transformed in technological innovation. In the...

We develop a growth model that features the endogenous two-tier innovations of information carrier technology and production technology. Information carrier technology promotes production technology innovation and thus economic growth through improving the preservation and dissemination of...
