What are the production costs of a facetoface economics class in the short run? (Production costs - NOT Consumer costs!) Consider the xed costs and the variable costs in the short run. What is the marginal cost of enrolling more students in a single class? What does that say about classroom size (number of students?) Based on your analysis, would a college prefer to have two economics classes with 25 students each, or one class with 40 students? Remember, I am asking about the costs to produce the face-to-face class, not the cost to students
