- Suppose that each firm in a competitive industry has the following costs: Totalcost:TC=50+1/2q2 Marginalcost:MC=q where q is an individual firm's quantity produced. The market demand curve for this product is Demand:QD=120−P where P is the price and Q is the total quantity of the good. Currently, there are 9 firms in the market.1. Give the equation for the market supply curve for the short run in which the number of firms is fixed.2. What is the equilibrium price and quantity for this market in the short run?3. In this equilibrium, how much does each firm produce? Calculate each firm's profit or loss. Is there incentive for firms to enter or exit?4. In the long run with free entry and exit, what is the equilibrium price and quantity in this market?5. In this long-run equilibrium, how much does each firm produce? How many firms are in themarket?Each of the 10 firms in a competitive market has a cost function of C=5+ q? The market demand function is Q = 420 -p. Determine the equilibrium price, quantity per firm, and market quantity The equilibrium price is $ (Enter your response as a whole number) The quantity per firm is q=units. (Enter your response as a whole number) The market quantity is Q=units. (Enter your response as a whole number)consider a market with a large number of firms, an upward sloping supply curve S0, and a downward sloping demand curve D0. We will start with the assumption that the market is perfectly competitive; hence, the supply curve S0 is the sum of the marginal cost curves of all the firms. Assume the market is perfectly competitive. Indicate the original competitive equilibrium price P0, equilibrium quantity Q0, the resulting Consumer Surplus CS0, the resulting Producer Surplus PS0, and the “socially optimal” output (the output the Benevolent Dictator would choose) QSO on your graph. Graphically indicate the size of Dead-Weight Loss DWL0 if there is such a loss. Question - Now suppose that scientists discover that this particular product has a significant Positive Externality. The Demand curve is a depiction of marginal private benefit (MPB). However, the existence of the positive externality means that for every given output level, Marginal Social Benefit (MSB) is higher than Marginal…
- Consider the daily market for hot dogs in a small city. Suppose that this market is in long-run competitive equilibrium with many hot dog stands in the city, each one selling the same kind of hot dogs. Therefore, each vendor is a price taker and possesses no market power The following graph shows the demand (D) and supply (S = MC) curves in the market for hot dogs.

If more than one firm choose the same price the demand is divided equally among them. There are no other firms in the market. Two firms have the same constant marginal cost cL and the third one has a higher marginal cost cH : cL < cH . Explain what will be the equilibrium price in this market.
- Initially, all firms in a perfectly competitive market are in long-run equilibrium. Assume that the market demand for the product produced by the firms in the market suddenly rises. Suppose the following graph shows the marginal revenue (MR) and marginal cost (MC) curves of a firm in this market at its initial long-run equilibrium, with an equilibrium price of P₁ and a profit-maximizing quantity of output of Q₁. Show the short-run effect of the increase in market demand on this firm by shifting the marginal revenue curve, the marginal cost curve, or both on the following graph.

Production possibilities frontiers can shift upwards without an increase in resources. The demand for a commodity increase when the price of its substitute increases. The income elasticity of the demand for luxury goods is always positive. Under perfect competition, a firm fix its price where its AR=MR
