Determining Short-Run and Long-Run Equilibrium Using Calculus

A market for a particular good consists of 40 identical firms. The supply function for a single firm is given by the equation q = 2P - 8, where 'q' is the quantity supplied by the firm and 'P' is the market price. What is the market supply function (Q) for this good?

A market consists of two types of firms. There are 10 firms of 'Type A', each with an individual supply function of q_A = P - 5. There are also 20 firms of 'Type B', each with an individual supply function of q_B = 2P - 10. Assuming the market price (P) is high enough for both types of firms to produce a positive quantity, what is the total market supply function (Q)?

A market consists of only two firms, Firm 1 and Firm 2. The quantity supplied by Firm 1 is given by q₁ = P - 8, and the quantity supplied by Firm 2 is given by q₂ = 2P - 20. Which equation represents the market supply function (Q) when the market price (P) is between $8 and$10?

In a competitive market with 50 identical firms, the total market supply is described by the function Q = 100P - 500, where Q is the total quantity supplied and P is the price. What is the supply function (q) for a single, individual firm in this market?

Individual vs. Market Supply Responsiveness

Local Coffee Market Supply Analysis

A market contains two firms. Firm 1 will begin to supply goods only if the price is above $5. Firm 2 will begin to supply goods only if the price is above$10. Both firms have individual supply curves that slope upwards. If the market supply curve is drawn with price (P) on the vertical axis and quantity (Q) on the horizontal axis, which statement best describes its shape?

Deconstructing a Market Supply Function

A market for a specific product consists of only two producers, Firm A and Firm B. Their individual supply schedules, showing the quantity each is willing to supply at different prices, are given below.

Firm A Supply:

Firm B Supply:

Which of the following tables correctly represents the total market supply schedule?

A market for a particular good consists of 40 identical firms. The supply function for a single firm is given by the equation q = 2P - 8, where 'q' is the quantity supplied by the firm and 'P' is the market price. What is the market supply function (Q) for this good?

Deriving Market Supply with Heterogeneous Firms

A competitive market for widgets has 50 identical firms. The total market supply is described by the equation Q = 100P - 500, where Q is the total quantity supplied and P is the price. Assuming all firms have the same supply function, what is the supply equation (q) for a single firm?

Relationship Between Individual and Market Supply Elasticity

A market for a product consists of two firms, Firm 1 and Firm 2. Their individual supply functions are as follows:

• Firm 1: q₁ = P - 10, for any price (P) greater than or equal to $10.
• Firm 2: q₂ = 2P - 40, for any price (P) greater than or equal to $20.

Which of the following equations correctly describes the total market supply function (Q)?

Deriving a Kinked Market Supply Curve

In a market where 20 identical firms are producing a good, the market price must rise by $0.50 to increase the total quantity supplied by 100 units. If 20 more identical firms enter this market, it is true that the market price would now need to rise by$1.00 to achieve the same 100-unit increase in total quantity supplied.

Consider three different markets for the same product, each with different firm compositions. Match each market description to the most likely characteristic of its short-run market supply curve. Assume all individual firms have upward-sloping supply curves.
