37 Внешние Эффекты Производство Price Quantity Bought and Sold Cпрос частная ценность Предложение (частные издержки) £5 100 MSC + MPC £12 Издержки загрязнения £7 80 Socially efficient output is where MSC = MSB оптимум

38 Market Failure External benefits by products of production and decision making that raise the welfare of a third party
