Lecture 7- chapter 11- technology, production and costs. Implicit cost- a nonmonetary opportunity cost (ex: forgone salary or economic. 3 key facts: marginal cost (mc), average total cost (atc) and average variable cost (avc) curves are all u shaped, and the marginal cost curve intersects both the avc and atc at their minimum points. If mc is below atc or avc, then they decrease. If mc is above atc or avc, then they increase. If mc= atc or avc, then they are at their minimum points: as output increases afc gets smaller this is because q (quantity) is increasing and. Fixed costs are remaining constant (aka- (cid:862) preadi(cid:374)g o(cid:448)erhead(cid:863)(cid:895: as output increases the difference between atc and avc decreases because the difference between atc/avc is afc (which decreases as output increase, as just mentioned) In the long run all costs are variable- there are no fixed costs in the long run tc=vc.
