This paper explores the structural determinants of high-growth firm shares in Austrian regions. The regional level of analysis
allows one to uncover regularities that are not detectable in firm-level studies. It is found that lower mobility barriers,
firm exits and technological opportunities, measured by digitalization intensities, and, to a lesser extent, agglomeration
effects are associated with a larger share of high-growth firms. The results suggest that comparisons of shares of high-growth
firm across countries and regions should consider differences in the industrial structures together with the often-emphasized
differences in policies and regulations.
This paper examines how product relatedness and the breadth of technological search affect the path-dependent development
of export specialisations across countries documented in prior research. The results of the econometric analysis in this paper
show that broader technological search in an industry has a positive impact on the development of comparative advantages in
the product lines it exports. The interplay between product relatedness and the scope of technological search has a two-edged
character. On the one hand, broader technological search supports adjustments and consolidations of the export baskets on
the extensive margin. This contributes to weaken path-dependency. On the other hand, it fosters the competitiveness of products
that are related to current export specialisations, and thereby promotes path-dependency on the intensive margin of trade.
These results differ across countries with different levels of technological capabilities.
