Pricing is determined based on supply and demand through the interaction of buyers and sellers in the market. When the demand for a product or service increases and the supply remains constant, the price tends to rise as buyers are willing to pay more to secure the limited supply. Conversely, when the supply of a product or service increases and the demand remains constant, the price tends to decrease as sellers compete to attract buyers. Ultimately, the equilibrium price is reached where the quantity demanded equals the quantity supplied, and this is where the market price is determined. **

Demand-oriented pricing strategies, such as price skimming and price discrimination, allow businesses to maximize their profits by setting prices based on customer demand and willingness to pay. This can result in higher margins and increased revenue. However, these strategies may also lead to customer dissatisfaction and backlash if they perceive the pricing as unfair or discriminatory. On the other hand, competition-oriented pricing strategies, such as price matching and penetration pricing, allow businesses to stay competitive in the market and attract customers with lower prices. This can help businesses gain market share and increase their customer base. However, it may also lead to lower profit margins and potential price wars with competitors, ultimately impacting the bottom line. **

In perfect competition, the pricing policy is determined by the market forces of supply and demand. Prices are set at the equilibrium point where the quantity supplied equals the quantity demanded. Firms in perfect competition are price takers, meaning they have no control over the price and must accept the market price. This leads to a situation where all firms in the market charge the same price for their products. **
