In this study we test the trade Global Engagement hypothesis in which firms more globally engaged – either multinationals or exporters – are more innovative. The test is applied to 4818 Portuguese enterprises´ data for the period 2002-2004 through the use of the fourth Portuguese Community...

In this study we re-evaluate the impact of natural resources on economic growth. The reassessment is based on a growth model where, using panel-data analysis, natural-resource variables (geographically diffused and concentrated) affect the efficiency gains of labour and capital in production. We...

This paper analyzes the mechanisms, other than market size, through which international trade of intermediate goods incorporating state-of-the-art technological knowledge affects accumulation of human capital and wage inequality in the North and South. Under North-South technological diffusion,...

The literature identifies North-South disparities in Total Factor Productivity (TFP), which, in turn, justify the bulk of international income differences. By building a dynamic, general equilibrium model of North-South technological-knowledge diffusion with scale-invariant growth, we extend the...

The explanation of the recent increase in intra-country wage inequality in favour of high-skilled labour has been dominated by two explanations: skill-biased technological change (SBTC) and international trade (IT) liberalization. Since few empirical studies have tried to assess both...

This paper studies the effects of the diffusion of a General Purpose Technology (GPT) that spreads first within the developed North country of its origin, and then to a developing South country. In the developed general equilibrium growth model, each final good can be produced by one of two...

Based on an extended model of endogenous directed technical change and on cross-country data, we identify and quantify the long-run link between: (i) the technology structure (high- vs. low-tech sectors) and the skill structure (high- vs. low-skilled workers), by considering an explicit role for...

We develop a general equilibrium endogenous growth model in which final goods can be produced either in the Non-Observed Economy (NOE) or in the Official Economy (OE). In particular, by solving transitional dynamics numerically towards the unique and stable steady state, we show that, by...

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...
