The debate on whether COVID-19 vaccine patents are slowing down the pace of vaccination and the recovery from the crisis has brought the optimal design of pharmaceutical patent policy to the fore. In this paper we evaluate patent policy in the US pharmaceutical industry. We estimate the effect...

We construct a model of innovation incorporating R&D externalities, R&D participation, financial market imperfections, and application and allocation of R&D subsidies, estimate it using Finnish R&D project level data and conduct a welfare analysis. The intensive, not the extensive R&D margin is...

This paper studies the welfare effects of R&D subsidies. We develop a model of continuous optimal treatment with outcome heterogeneity where the treatment outcome depends on applicant investment. The model takes into account heterogeneous application costs and identifies the treatment effect on...
