Innovation and Local Labour Markets: A Panel Analysis of France, Germany and the UK
This paper considers the effect of innovation, measured by patent applications, on regional employment and earnings in the UK, France and Germany. I use a panel estimation strategy to model the feedback effects between patenting and graduate employment as well as their joint effect at the NUTS2 regional level. Isolating the variation of graduate employment induced by innovation shocks, I estimate the direct effect of innovation on earnings and non-graduate employment, as well as the indirect effect through an increase in graduate employment. The results confirm a positive feedback effect between patenting and graduate employment. However, the effects on non-graduate employment are highly variable by country.

Labour shares and industry concentration: A regional analysis of Great Britain
Falling labour shares are a concern for economists in many developed and emerging economies around the world. This trend has been linked to growing industry concentration, as growing market power allows firms to charge mark-ups over marginal cost. I show that both of these trends also characterise the economy in Great Britain over the last two decades. Moreover, businesses that are dominant in their industry are predominantly located in London and the South East, as well as other urban areas. I estimate that the labour share would be around 1 percentage point higher in 2014, had industry concentration not increased since 2002 The difference is larger in urban than in predominantly rural areas.
