The Theory Of The Firm Under Perfect Competition

This section discusses how firms in a perfect competition market determine the optimal level of production to maximize profits.

Perfect Competition: Defining Features

This section discusses the key features of a perfectly competitive market, highlighting how they lead to price-taking behavior among firms.

Revenue

This section explores how firms in a perfectly competitive market determine their total revenue, average revenue, and marginal revenue, emphasizing the relationship between price, output, and revenue.

Average Revenue And Marginal Revenue

This section explores the concepts of Average Revenue (AR) and Marginal Revenue (MR) within the context of a perfectly competitive market, illustrating their equivalences to market price and their implications on a firm's revenue and profit maximization.

Profit Maximisation

In this section, the conditions under which a firm maximizes its profits in a perfect competition market are outlined, including the importance of price and marginal cost.

Condition 1

This section outlines the profit maximization condition for a firm in perfect competition, emphasizing that profit is maximized when marginal revenue equals marginal cost.

Condition 2

Condition 2 explores the requirement that the marginal cost curve cannot slope downwards at the profit-maximizing output level in a competitive market.

Condition 3

Condition 3 outlines the necessary price relationship for profit maximization in a competitive market, emphasizing the need for price to exceed average costs in both the short and long run.

The Profit Maximisation Problem: Graphical Representation

This section explores the graphical representation of a firm's profit maximisation problem in the context of perfect competition.

Supply Curve Of A Firm

This section explores the concept of a firm's supply curve in a competitive market, detailing how it is derived based on the firm's response to varying prices.

Short Run Supply Curve Of A Firm

This section discusses the derivation of a firm's short-run supply curve in perfect competition, focusing on how firms respond to different market prices.

Long Run Supply Curve Of A Firm

This section discusses how firms determine their long run supply curves based on profit maximization conditions, which include costs and market price dynamics.

The Shut Down Point

The shut down point for a firm is defined where it ceases production due to prices falling below the average variable cost in the short run, and the minimum average cost in the long run.

The Normal Profit And Break-Even Point

Normal profit is the minimum profit needed to keep a firm in business, while the break-even point is where total revenue equals total costs.

Determinants Of A Firm’s Supply Curve

This section describes the key determinants that affect a firm's supply curve, emphasizing technological progress and input prices.

Technological Progress

This section discusses the impact of technological progress on a firm's supply curve, highlighting how innovation can lead to increased production efficiency.

Input Prices

This section discusses how changes in input prices affect a firm's supply curve in a perfectly competitive market.

Market Supply Curve

The market supply curve represents the total quantity of goods that all firms in a market are willing to produce at different price levels.

Price Elasticity Of Supply

This section discusses the concept of price elasticity of supply, which measures how responsive the quantity supplied of a good is to changes in its price.
