Short description

Labour productivity growth is one of the main contributors to an economy's competitiveness and rising prosperity. The following publications focus on the impact of intangible capital investment on labour productivity growth.

Ongoing Research Projects: GLOBALINTO

GLOBALINTO will provide new measures of intangible assets at the firm level, filling an important gap in measurement which has restricted statistical production, micro-based analysis and evidence-based policymaking. GLOBALINTO will analyse the various potential explanations of the productivity puzzle, both at micro and macro levels. PD Dr. Roth leads Macro Work Package 6 (WP6) and with his team, he is involved in the realization of the work results D6.1, D6.2, D6.6, and D6.7. Furthermore, they are also working on D2.1, D5.11 and D7.4. 
The main objective of WP6 is to use EU wide industry-level data to explore the relationship between intangible inputs & productivity and innovativeness performance. In D6.1, the relationship between intangible and labor productivity growth will be investigated using the newly created D6.2 database. D6.2 decodes the value chains of innovations using the ‘World Input-Output Database’ (WIOD) from Eurostat and the input-output data from Eurostat. Furthermore, the data on intangible assets in Europe will be formulated in web form. D6.6 analyses the productivity of economic sectors in all EU countries and develops policy plans on how financial support and other incentives such as tax breaks or exemptions can be linked to financing bottlenecks. D6.7 develops empirical results from the analysis of novel data and existing intangible assets (Horizon2020, SPINTAN data, INTAN-Invest Research Collaboration). 
In work D2.1, PD Dr. Roth develops key concepts for intangible assets and measurements of company productivity based on Work Package 1. D2.1 deals with different approaches to conceptualization and measurement taking into account the differences in the data infrastructure in the EU countries. In addition, D5.11 contains a scientific article on the relationship between intangible capital investment and labor productivity growth in Germany between 2007 and 2017. D7.4 analyses the role of supply-side and demand-side policies in fostering productivity growth and the relationship between the rule of law and corporate intangible investment. This assessment will form the basis for identifying the need for policy action.
