Productivity and Innovation


Research profile

The focal goal of the "Productivity and Innovation" research area is the empirical understanding of the input and output drivers of firm performance by means of the analysis of sectoral and micro-datasets from the official statistics. A particular focus lies on the assessment of comparable datasets developed within international research consortia including, for example, on small and medium enterprises (SME) and intangible capital.

Methodologically, our empirical analysis is based on parametric and non-parametric productivity decompositions and efficiency analysis as well as the structural estimation of production functions. These techniques are, in particular, applied to the study of efficiency and productivity growth in research and knowledge intensive services. Efficiency analysis’ is specifically used to investigate performance of utilities in network industries within the Leibniz Project on the "Efficiency of Municipal Infrastructures".

A major driver of productivity growth is innovation. The main focus of this research area lies on the study of the effectiveness of different policy tools aiming at fostering innovation as well as the growth and performance of firms, industries and geographical regions. Of particular interest are those policies and innovations that help reducing the input of natural resources as well as the environmental burden of economic activities. Therefore, we put a particular emphasis on the study of the economic impact of a greening of the economy. Productivity enhancing agglomeration effects can be reached through the exploitation of firms’ economies of scale and scope as well as regional knowledge spillovers. Hence, geographical structures play a crucial role for the performance and competitiveness of an economy. Therefore, one of the focuses of our research in this field lies in the identification and analysis of geographical specialization-clusters in Germany and Europe.
