Term | Definition |
---|---|
perfectly competitive | lack of market share (no 1 firm has control over price in market); standardized product (don't know where your good came from); close to free entry/exit (easy for a firm to leave/join market; ex= agriculture) |
profits | profits = (P*Q) - TC; firms choose Q to maximize profits; can't change price bc it's a perfectly competitive market and you can't do that |
marginal revenue (MR); profit-maximizing principle of marginal analysis | MR = (change in total revenue) / (change in quantity); choose to increase/decrease Q based on if MR ≥ MC for 1 more; MR = price in a perfectly competitive market |
MR curve for perfect competition | MR=P; whatever firm sells good at is market price because you can't change the price; therefore MR=P |
