Price-output determination in perfect competition can be explained through the following steps:

1. In perfect competition, there are many buyers and sellers in the market, and all firms produce identical products.

2. Each firm in perfect competition is a price taker, meaning they have no control over the market price. They can only adjust their output level based on the prevailing market price.

3. The market demand and supply curves determine the equilibrium price and quantity in perfect competition. The market demand curve represents the aggregate demand for the product, while the market supply curve represents the aggregate supply.

4. At the equilibrium price, the quantity demanded by buyers equals the quantity supplied by sellers. This is the point where the market is in balance.

5. If the market price is above the equilibrium price, there will be excess supply, leading to a downward pressure on prices. Firms will reduce their output to match the lower demand, and the market will eventually reach the equilibrium.

6. Conversely, if the market price is below the equilibrium price, there will be excess demand, leading to an upward pressure on prices. Firms will increase their output to meet the higher demand, and the market will eventually reach the equilibrium.

7. In perfect competition, firms can freely enter or exit the market in the long run. If firms are making profits, new firms will enter the market, increasing the supply and driving down prices. If firms are incurring losses, some firms may exit the market, reducing the supply and driving up prices.

8. As a result of this process, in the long run, firms in perfect competition will earn normal profits, where total revenue equals total cost. This occurs when the market price equals the average cost of production.

Overall, price-output determination in perfect competition is driven by the interaction of market demand and supply forces, with firms adjusting their output levels to match the prevailing market price.
