Resumo(s)
The effects of the Portuguese R&D tax credit (SIFIDE) on R&D investment are assessed using
Nearest Neighbor Matching and Difference-in-Differences. The impact is tested in the year the
program is reintroduced allowing matching in the absence of the instrument. The impact is
measured over almost the universe of corporations but requires the use of Intangible investment
as a proxy for R&D expenditure. The hypothesis of full crowding-out is rejectd. The
specification is repeated at a smaller sample level to contrast the proxy with actual R&D
expenditure and similar results with higher significance are obtained.
