Dynamic R&D Investment (with Mordecai Kurz and Kenneth Judd)

Summary

We study a dynamic investment game in which firms are differentiated by their R&D stocks and therefore productivities. When investing in R&D, firms face "success-breeds-success" probabilities, where accumulated successes improve their subsequent investment productivity. The government may seek to restrain firms' growth and create a more level playing field. We characterize the optimal policy under uncertainty.
