If we repeat the same analysis for the second function, we see that it could be concave and therefore it could be quasiconcave. The sublevel and the superlevel sets of quartile x are convex seeproblem 2. This is readily shown by induction from the definition of convex set. This defines a convex set. EEa Homework 2 solutions. In general, f p is not quasiconvex.
Therefore, f is convex and quasiconvex. It is quasiconvex and quasiconcave i. Website Designing by digiverti. Homework Solutions, 1, 2, 3. In other words, concavity models the effect of satiation.
