Abstract
We create a mathematical model with a system of nonlinear ordinary differential equations to study how safe social casino gambling is for elderly women. Older women develop gambling problems significantly faster than their male counterparts, which is a typical characteristic of electronic machine gambling. We study dynamics of the system through stability analysis and numerical simulations. We find that an exposure to a casino involves a significant risk; casino gambling is present in an endemic state; problem casino gambling among the elderly women is decreasing in the long run; the model is most sensitive to the initial exposure.
