This paper explores the effect of different regional technological profiles on the resilience of regional economies to exogenous shocks. We conduct an empirical examination of the determinants of resilience through panel analyses of UK NUTS III level data for the 2004-2012 period. The results indicate that regions endowed with technologically coherent – and not simply diversified – knowledge bases are better prepared to face an unforeseen downturn and display resilience. Moreover, local economies tend to be more adaptable if they innovate in sectors with the strongest growth opportunities, even though firms’ net entry does not appear to contribute significantly towards resilience.

# 13.02 Related Variety, Unrelated Variety and Technological Breakthroughs: An analysis of U.S. state-level patenting

We investigate how variety affects the innovation output of a region. Borrowing arguments from theories of recombinant innovation, we expect that related variety will enhance innovation as related technologies are more easily recombined into a new technology. However, we also expect that unrelated variety enhances technological breakthroughs, since radical innovation often stems from connecting previously unrelated technologies opening up whole new functionalities and applications. Using patent data for US states in the period 1977-1999 and associated citation data, we find evidence for both hypotheses. Our study thus sheds a new and critical light on the related-variety hypothesis in economic geography.
