The slides and answers for today's quiz are up. The grades will be up soon. I'll send another email when the Week 4 overview is up.
Next week, we'll study the individual firm's cost-minimization problem, which is very similar to the consumer's problem. We'll derive a cost function — how much it costs to produce q units — and use it to re-examine the Supply curve.
The midterm next Friday will (probably) have four long numerical/graphical questions and several shorter questions. I'll give more details later. Have a good weekend,
