What is the relationship between marginal revenue (MR) and the demand curve (is MR greater, equal, or less than the demand curve)?arrow_forwardyou've been learning about what makes a market perfectly competitive, how a firm in a perfectly competitive market makes profit-maximizing decisions, and how a perfectly competitive market moves towards equilibirium. But how applicable is this to real life? For this discussion, try to think of a market (for a product or service) that is perfectly competitive or very close to it. What characteristics of the market make it like perfect competition? Are there factors that keep it from being perfectly competitive? If so, what are they? How close do you think the firms in this market are to perfectly competitive firms in choosing equilibrium price and quantity?arrow_forward
