 Nov 30 revised Visualization tools for game theory: Game trees added 989 characters in body Nov 30 answered Visualization tools for game theory: Game trees Nov 23 comment Short Run Total Cost function Question You're right, this production function does not make much sense because $F(K = 0,L) < 0$ for $L < 1$. You can have an additional constraint that at least one unit of labor must be hired i.e. $L\geq 1$ to get away with this problem. Nov 19 comment How to show that the estimator is consistent? The next step is to infer that what you have is not a consistent estimator. The reason is $\frac{U_3-U_2}{X_3-X_2}$ does not vary with the sample size and will always have the same variance. Nov 15 comment How can I prove that the following estimator is biased? For convex function $g$, $\mathbb{E}(g(X)) \geq g(\mathbb{E}(X))$. If $g$ is strictly convex then inequality is strict: $\mathbb{E}(g(X)) > g(\mathbb{E}(X))$. Nov 15 comment How can I prove that the following estimator is biased?

"Convex" indifference curves does not imply quasiconcave utility function. Consider $u = -xy$, $u$ has convex ICs but it is not quasiconcave. Nov 4 answered Does quasi-concave utility function imply convex indifference curve? Nov 1 answered How is the utility function with constant relative risk-aversion obtained? Nov 1 awarded Announcer Oct 30 comment Why is the nature of graph of utility function different from indifference curve? You can refer to qr.ae/TWvVSr for answer.
