The acknowledged importance of innovation and the increasingly decisive role played by the service sector make innovation an issue of major relevance to the economy. Using a sample of 6593 companies that answered the Community Innovation Survey 2008, we assessed the determinants of innovation of...

We present a unified graphical framework accounting for the nature and impact of spillover effects. The dynamics of the learning process with a specific spillover transfer mechanism can be illustrated by recurring to this four-quadrant picture. In particular, a whole cycle of technological...

Within a debatable framework of ‘natural replication’ of well-succeeded cases such as the Silicon Valley, Route 128, OECD countries have been implementing policy measures directed to the stimulation of the development of regional clusters composed by Technology-Intensive Firms (TIF) around...

The importance of promoting innovation has been elevated up to a status of official standard since the Lisbon European Summit in 2000. Here research and development (R&D) was singled out as an essential element of the foundation on which innovation could be built. R&D has been a growing area of...

Existing illustrations of the learning phenomenon either stress the relationship between flows and stocks, neglecting the chronological time variable, or the speed of knowledge accumulation along time, neglecting the nature of the underlying learning process. In this paper we present a graphical...

In the past Portugal managed to grow at a significant rate, but the pace has getting slower and slower from decade to decade, until becoming practically stagnant in the first decade of the 21st century. This stumpy growth together with the current debt crisis has fed the rhetoric of structural...

This paper deals with the relationship between innovation and economic growth in the context of developed world. After examining the correlation between economic growth and R&D (research and development) intensity, and given that the impact of R&D on economic growth is mediated by the rate of...

Given that science and technology are inductors of economic development, the emergence of a knowledge-based economy creates an overlay of communications and expectations that have led to institutional restructuring based on innovative capacities. While the literature tends to concentrate on...

It is widely recognized that scientific research has a dramatic impact on economies since it is crucial to foster technological knowledge. Today’s migratory movements and concentration of highly educated population and population with high scientific potential in developed countries play an...

We examine the behavior of the skill premium in a two-country general equilibrium growth model assuming (i) technological-knowledge diffusion; (ii) internal costly investment in both physical capital and R&D; and (iii) complementarities between intermediate goods in production. We find that these...
