We investigate a firm's incentives to conceal an intermediate research discovery in order to influence its rival's choice of strategy in an innovation race. To study this, we introduce an innovation game where two firms dynamically allocate their resources between two distinct research and...

The Moment-SOS hierarchy initially introduced in optimization in 2000, is based on the theory of the K-moment problem and its dual counterpart, polynomials that are positive on K. It turns out that this methodology can be also applied to solve problems with positivity constraints “f(x) larger than...
