We introduce a generalization of convexity called projective-convexity (or P-convexity) which extends models for consumer preference and consumer budgeting. We prove a separation theorem for projectively-convex sets, establish a duality theorem for projectively-concave technologies, and briefly analyse extremal properties of projectively-concave functions.
