<title>Abstract</title> We develop a R&D-based growth model with productive public expenditure in order to frame the Quadruple Helix (QH) innovation concept, based on four helices: <italic>Academia & Technological Infrastructures</italic>, <italic>Firms</italic>, <italic>Government</italic> and <italic>Civil Society</italic>. Our motivation stems from acknowledgment that the...

Multidisciplinary innovation is the main engine of growth for an increasing number of economies. Innovation requires the participation of and interaction between all economic agents. It also requires public spending on education, research and infrastructures. Our main goal is to emphasize the...

We analyse the skill premium and the growth rate in an innovator-imitator general equilibrium growth model assuming (i) internal costly investment in both physical capital and R&D, (ii) complementarities between intermediate goods in production and (iii) technological-knowledge diffusion. We...

The theoretical richness and variety of the new growth literature can make it difficult to capture the essence of growth models. With this paper, we wish to provide one possible integrating view of the nature of the growth generating processes. Revisiting the models that constitute the core of...

We propose a new framework to analyse the relationship between the relative high-skilled labour endowment, the skill premium and economic growth. Building on Acemoglu and Zilibotti (2001), we introduce physical capital; internal costly investment in both capital and R&D; and complementarities...
