This paper studies programme synergy effects in the additionality of research and development (R&D) subsidy output. Using the inverse probability weighted regression adjustment estimator on data from nine programmes for direct public support of business R&D in the Czech Republic, we find that output additionality effects are weakly skewed toward firms participating in multiple programmes, but that the benefits tend to be rather short-lived. Both cross-sectional interaction effects of participating in multiple programmes at the same time and intertemporal learning effects of participating in programmes repeatedly are initially positive but largely fizzle out after few years. These findings caution governments against fragmenting the innovation policy mix into too many similar programmes and rather consider providing firms with comprehensive one stop shop interventions. The interaction effects between R&D subsidy programmes also increase the complexity of programme evaluation.
