Is There Really an Inverted U-shaped Relation Between Competition and R&D?
() and Andreas Poldahl
Abstract: We test whether predictions of the Aghion and Howitt
(2004) model are supported by firm level data. In particular, we analyze if
there is an inverted U-shaped relation between competition and R&D. Results
show that the inverted U-shaped relation is supported by the Herfindahl
index but not by the price cost margin. Using the Herfindahl index results
suggest that breaking up monopolies increases R&D while further increases
in competition most likely leads to reduced R&D. Comparing different
estimators, we find that time-series based estimators typically result in
less clear-cut results, probably driven by a lack of time series variation
in measures of competition.
