Posted by Jedd on 2/13/17 6:06 PM

Giving Choices to Younger Students

Students in grades 4-10 tend to face very different challenges when preparing for their tests. The youngest students are unfamiliar with such a prescribed set of learning goals, so distinct from the kind of open-ended and holistic kind of learning common across public and private elementary schools. For these students, they may never have experienced academic learning as a process of wresting with challenging, new content, particularly so much at once and in such a specialized context.

Marginal Rate of Substitution (MRS), Marginal Utility (MU), and How They Relate

Posted by Emily on 2/3/17 5:52 PM


In this post, I start off explaining the Marginal Rate of Substitution (Sections II-IV). Then, I cover the concept of Marginal Utility (Sections V-VII). In both cases, I start with a story explanation, then give a formal definition, and finally provide some other useful information about the concept. After that, I connect the two concepts (Marginal Utility and Marginal Rate of Substitution) and show how they relate mathematically, first without calculus (Section VIII) and then with calculus (Section IX). Finally, I demonstrate that the Marginal Rate of Substitution has an advantage over Marginal Utility in terms of describing preferences and behavior (Section X), because it is less sensitive to the exact utility function you choose to use.
