New technologies are becoming omnipresent in many economic applications, from competitiveness and productivity to market power. Understanding their interactions with internationalization is critical to gain insight into economic growth, but an organic and unified approach to the study of these types of assets is currently lacking in the literature, firstly in terms of a precise definition and secondly with regard to the consequences on the economy. In this project, we contribute to the literature by studying the impact of intangible assets and internationalization on productivity, competitiveness, market power and the labour market. First, we will precisely classify intangible assets, drawing on contributions from multiple data and approaches. Secondly, we will study their impact on a wide variety of macroeconomic variables and phenomena, both empirically and analytically.
