Computer Code for "Research among Copycats: R&D, Spillovers, and Feedback Strategies"

In the accompanying folders we provide programme code that can be used to replicate the results in our article "Research among Copycats: R&D, Spillovers, and Feedback Strategies". There are two groups of programmes: i) Fortran code to compute the feedback Nash equilibrium value function and the corresponding drift vector field; ii) Matlab code to compute all derivative results and plots. Also attached is a document with welfare simulations that supplements Section 4 (Welfare Effects of Spillovers) of our article.
