Cover Story: Investment in R&D has increased significantly in recent years in high-tech industries. In this work, we study how to optimally allocate resources to R&D via a framework based on a dual risk model. In a dual risk model the costs are continuous in time, while the gains happen in discretely random times, analogous to the nature of R&D. As investing in R&D increases, so do the running costs and the frequency of resulting gains. Our framework targets the problem by finding a strategy that minimizes the probability of ruin. We identify cases where investment in R&D significantly decreases the probability of ruin. View this paper
