Revised (140 words): The lecture mainly discusses dynamic pricing, which refers to how the price changes depending on various factors. The first factor that affects dynamic pricing is the availability of goods. For instance, if an airline has limited seat availability on a specific day and time, consumers are more willing to pay for the seats due to scarcity. Consequently, the company can raise the price and earn more profit. Another factor influencing dynamic pricing is competition among sellers offering similar products. For example, when purchasing a book online, customers can compare prices across different stores. By monitoring competitors' prices and adjusting their own accordingly, businesses can attract more customers and increase sales. Overall, dynamic pricing is a strategy that allows companies to maximize profits by considering factors such as product availability and market competition.
