<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...

Innovation is the main engine of growth in an increasing number of economies. Innovation economies are, according to the Quadruple Helix (QH) Innovation Theory, sustained by four pilars – Firms, Academia, Government and Consumers –, all operating in a systemic, interactive environment. We...

We propose a theoretical growth model with which to frame analytically the Quadruple Helix Innovation Theory (QHIT). The aim is to emphasise the investment in innovation transmission mechanisms in terms of economic growth and productivity gains, in one-high-technology sector, by stressing 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...

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...

We propose a new framework to analyse the wage premium behaviour. Building on Acemoglu and Zilibotti (2001), we introduce physical capital and two assumptions: (i) internal costly investment in both capital and R&D; (ii) complementarities between capital goods in production. We find that, for...

Multidisciplinary innovation is the engine of growth of an increasing number of economies. Innovation output depends increasingly on information sharing and cooperation between creative agents. Sharing and cooperation requires the existence of generalised trust. Social capital consists of trust...
