An important policy question is whether research and development (R&D) in new, emerging technologies should be more subsidized than R&D in other more mature technologies. In this paper I analyze if innovation externalities caused by knowledge spillovers from private firms may warrant a...

We analyze how knowledge spillovers influence the optimal timing of R&D policy. Using numerical simulations we find that optimal subsidies to R&D may be rising over time even when the returns to knowledge is decreasing. The optimal time profile of the subsidies is determined by the elasticity of...

The "resource curse" is a potential threat to all countries relying on export income from abundant natural resources such as fossil fuels. The early literature hypothesized that easily accessible natural resources would lead to lack of technological progress. In this article we instead propose...
