This paper contributes to the literature on determinants of export diversification by introducing related variety (RV) and unrelated variety (UV) in the analysis in addition to the traditional entropy based measure at three-digit SITC level, overall variety (OV). RV measures variety in...

This paper contributes to the literature on determinants of the export diversification by introducing related variety (RV) and unrelated variety (UV) in the analysis in addition to the traditional entropy based measure at three-digit Standard International Trade Classification (SITC) level,...

Diversity is considered key to research, innovation and growth. However, throughout the literature, the exact meaning of the notion of diversity is often left in the midst. What is more, whilst the relation between diversity and productivity growth by now has been extensively addressed, still...

The role of radical innovations for the economy has received increasing attention by German policy-makers. This paper investigates how (un-)related variety and external linkages influence these innovations in German labour market regions. Evidence is found that related and unrelated knowledge...

This paper investigates the effect of related and unrelated variety on regional growth in West Germany. In particular, we analyze the role of regional absorptive capacity and new business formation for these effects. We find that West German regions benefit from both types of varieties. The...

This article analyses how regional employment growth in Germany is affected by related variety, unrelated variety and the functions a region performs in the production process. Following the related variety literature, we argue that regions benefit from the existence of related activities that...

The paper investigates the effect of spatial agglomeration on firm exit. In particular, the role of specialization and local variety in production is addressed. The extent to which industrial clusters can be actually retained industrial districts is also considered. Empirical evidence is...

This paper analyses the effect of variety and intensity of knowledge on the innovation of regions. Employing data for Swedish functional regions, the paper tests the role of the variety (related and unrelated) and intensity of (1) internal knowledge generated within the region and also (2)...
