Characterizing the Evolution of the EU-US R&D Intensity Gap Using Data from Top R&D Performers (March 23). 2012 TRPC. Available at SSRN.



In this paper we look at the evolution of the R&D intensity gap between the EU and its major competitors using data from the Industrial Scoreboard covering the period 2002-2010. We focus on R&D intensity as it is normally recognized as an important determinant of the competitiveness of economic regions and we assess whether the gaps relative to major competitors arise from differences in industrial composition (structural component) or differences within sectors (intrinsic component). This is important from a policy perspective since the task of modifying the industrial structure is a much harder one. The paper is divided in two parts.

In the first part of the paper we first present the evolution of the R&D intensity gap between the EU and its major competitors (US, Japan, BRIC, Asian Tigers) and then we look more closely at the role and evolution of the structural and intrinsic component for each pair-wise comparison, by looking at four basic macro-sectors defined in term of their R&D intensity.

In the second part of our work we concentrate on the EU-US R&D intensity gap and, by applying firm level analysis, we test whether the results obtained by the statistical decomposition of aggregate R&D intensity are confirmed. The evidence provided by this exercise is especially important because it allows us to perform a comparison where the ceteris paribus condition is more likely to be satisfied. In particular we test whether there is evidence of across-sector variability in R&D intensity and whether, within sectors, EU and US firms are performing differently. To do this we have to control for various factors such as size, cyclical effects, common macroeconomic shocks and company’s age. Age is important for at least two reasons. First, young companies might have more problems in finding access to funds necessary in order to invest in R&D. Second, young companies might have to be especially aggressive in terms of innovation if they want to enter and succeed in markets where incumbents already exist. More generally, company age is important because it takes time to build, test and eventually change a given business model and there is plenty of evidence that young firms are those exhibiting the highest dynamism. Therefore, our aim here is also to document the age profile for R&D intensity and to verify whether the R&D intensity gap between EU and non-EU companies is related to age of the firm. Finally we check if R&D intensity is affected by the abundance of internal funds (as captured by the profit/sales ratio), if this relationship changes with the age of the company and if the latter shows across-regional variation.

Our results indicate that there is evidence of strong across-sector variation and some evidence of within-sectors-across-region variation, which –however- is not always in favour of the US. This allows us to conclude that firm level analysis confirms the results from the aggregate analysis. Moreover we find that R&D intensity tends to decrease as firm size increases (as measured by the number of employees), that the age profile for R&D intensity behaves very differently in the two regions and that young and middle age companies in the EU exhibit a much higher reactivity to lagged profits-to-sales ratio, when compared to their US counterpart. We believe that this is an indication that the conditions for accessibility and cost of funds differ significantly across the two regions.
