Abstract or Additional Information

Abstract: We model coupled decisions as a stochastic process. Specifically, we consider two particles subject to diffusion. When one of the particles escapes, it influences the other one. As theoretical background, a derivation of the diffusion equation from Ito calculus is resented. The diffusion equation is then solved with boundary conditions suitable for coupled decision making. From this, a probability density for the passage time of the first and second particles is obtained and compared with Monte Carlo simulations.
